AbstractThe water logging or even flood always occurs on Srikoyo road in every rainy season. The condition emerges because of the imbalance between the number of rainwater catchment area and the rapid increase of residential areas. Besides, the drainage channels along the road of Srikoyo are not sufficient enough to hold rainwater well. The process of evaluation is done by applying the method of hydrological analysis to determine the maximum discharge modeling used for evaluating the capacity of the existing drainage channels. The output of the hydrology analysis calculation comes up in rainfall intensity which is required as the data input for SWMM modeling. SWMM modeling is used in this evaluation since it is a model of rainfall-runoff simulation which is used for simulating both quantity and quality of the surface runoff of urban areas. The result of the evaluation using the software SWMM suggests that there are several number of water logging during the return period of 1, 2, 5, and 10 years. There are 3 areas encounter flood in the return period of 1 year, 10 areas in the return period of 2 years, 18 areas in the return period of 5 years, and 19 areas in the return period of 10 years.Keywords: SWMM, Flooding, Drainage, Evaluation AbstrakPada musim penghujan Jalan Srikoyo selalu tergenangi air. Terjadinya genangan di Jalan Srikoyo diakibatkan oleh area resapan air hujan tidak seimbang dengan pesatnya wilayah pemukiman. Selain itu, saluran drainase di sepanjang ruas Jalan Srikoyo kurang memadai dan tidak dapat berfungsi dengan baik untuk menampung air hujan. Dengan adanya permasalahan ini dilakukan proses evaluasi, evaluasi ini dilakukan dengan menggunakan metode analisis hidrologi untuk menentukan debit pemodelan maksimal yang digunakan untuk mengevaluasi kapasitas saluran drainase yang ada. Dimana output perhitungan analisis hidrologi berupa intensitas hujan yang diperlukan sebagai data inputan untuk pemodelan SWMM. SWMM digunakan dalam evaluasi ini dikarenakan SWMM merupakan model simulasi hujan-aliran (rainfall-runoff) yang digunakan untuk mensimulasikan kuantitas maupun kualitas limpasan permukaan dari daerah perkotaan.

Drainage Channels

A good road drainage system is needed to ensure that road user activities are not disrupted due to rain puddles. The cause of inundation that occurs is land use change, there is no drainage channel, the channel is not well connected, the channel is closed due to widening of the road without considering drainage channels. Given this, research needs to be carried out on the condition of the existing drainage system as a material consideration for evaluating its feasibility and planning a drainage system that is able to overcome the inundation that occurs. Writing this final project refers to primary data and secondary data that already exist. The rainfall data came from the Climatology and Geophysics Meteorological Agency, Balai Besar Region II, Bogor Regency, which is the Darmaga huajn rainfall measurement station and the PUPR Binamarga Office of Bogor Regency. Meanwhile, to find out the dimensions of the existing drainage channels obtained by conducting surveys and direct observation to the field. Data analysis which was carried out was hydrological and hydraulics analysis. Hydrological analysis includes the analysis of rainfall frequency, determining the repeat period, calculating the concentration time, analyzing the rainfall intensity, and calculating the flow flow plan. Based on the results of hydrological analyzes, the hydraulics analysis is then performed, such as calculating the plan channel profile and calculating the height of the planned channel guard. From all of these analyzes, the results of the drainage study on the Cigombong KM 16 - KM 23 highway were carried out, that is, the entire capacity of the existing canals was not able to accommodate the planned flow discharge for a return period of 2 years 5 years 50 years. In addition, the results of the analyzes that have been carried out show that the rain that occurs during a certain period of time and a certain return period greatly affects the planned drainage channel profile and is due to the large amount of garbage in the channel which affects the reservoirs in the drainage that often occur frequently

Pelambuan is a sub-district in West Banjarmasin, Banjarmasin City, South Kalimantan Province. Part of the Pelambuan area is still a slum area because there is no drainage, garbage problems, sanitation, etc. So it needs awareness and the role of community members to love the environment and live healthily. Thus, the residents must be given an understanding of the integrated environmental drainage system (ecodrain) in residential areas to maintain and create a healthy environment. In principle, ecodrain is a program to restore and improve the quality of urban drainage flow from pollution caused by garbage or wastewater due to the indiscipline of urban residents who throw garbage or wastewater into channels or rivers that cross urban areas. Handling of drainage, which is carried out in an integrated manner by handling waste and wastewater with an environmentally sound concept (ecodrain), can be carried out in the following ways: installation and operation of waste filters, application of proper waste management with the 3R approach (Reduce, Reuse & Recycle) community-based, community-based sanitation improvement (Sanimas), river water quality restoration through bioremediation, construction of rainwater catchment wells to reduce the volume of rainwater runoff that will flow into drainage channels and rivers.

Tarakan City experiences problems with standing water during the rainy season, especially in the west Tarakan sub-district which is the center of Tarakan. This puddle not only submerged settlements and offices but also shops and access roads that caused considerable economic losses. An evaluation was carried out by using the Storm Water Management Model (SWMM). SWMM is a rainfall-runoff simulation model used for simulating the quantity and quality of surface runoff from urban areas. Based on the evaluation using SWMM software, the drainage system in Tarakan, especially in Jalan Mulwarman has several inundated channels, namely channels 2, 3, 4, 5, 6, 7, 11, 12, 13, 14. This is influenced by the dimensions of the drainage channel that cannot accommodate existing water runoff and sediment thickness that covers the drainage channels so that the capacity is reduced, if it rains it will cause puddles at several points in Tarakan City. In order to deal with these puddles, it is necessary to change the dimensions of the channel and routinely dredge sediments that cover the drainage channels.

<p>Mediterranean coastal areas have been cultivated for long time. Wetlands areas situated near to the coast have been drainaged by using drainage channels. Heavy metals can be transferred from soils to the channels under agricultural management practices, especially under flood and furrow irrigation (the most important in the area studied). Anthropogenic inputs, including excessive use of agrochemicals and manure, in agricultural soils contribute to an increase of the content of some toxic heavy metals [1].</p><p>The agricultural area situated in the South of the province of Alicante has an important drainage system (avoiding to be a coastal wetland), which more than a thousand kilometers that allow the cultivation on calcareous soils (mainly Fluvisols).

Water samples were taking along the channels in three to ten points of each channel, depending on the length, and metals were analyzed following standard methods [2]. At the same time, the land cover has been analyzed by using the last data from National Aerial Orthophotography Plan (available from the National Center of Geographical Information, Spain).</p><p>The most important result obtained was that the presence of Cd in the waters was under the limit of detection of 0.1 μg/L. This result reflected the absence of pollution sources of this metal from soils to these drainage channels.</p><p>Moreover, in the case of Cr, the values obtained were even below the reference values ​​for drinking water [3]. However, the major concentrations of this metal were between 6 to μg/L in only 4 channels. Ni, whose concentrations were lower than those for Cr, has values under 7 μg/L. Heavy metal pollution, at least in the elements analyzed, does not seem to be a serious problem in terms of the quality of these waters.</p><p>Although many land cover changes have occurred, most of the soils are dedicated to agriculture.

The existing drainage system of roads proposed to manage the quantity of runoff from the road only, while the quality remains uncontrolled. In fact the pollutants and waste originated from the road surface contains hazardous substances. Sustainable drainage system (SUDS) concept offers various structures to solve both quantity and quality problems of surface runoff from roads. One of the potential drainage structure is filter drain or infiltration trench develope along the right side and left side of road. It could be developed by retrofitting the existing drainage channel of the road. The objective of this paper proposes the design model of road drainage based on the concept of a sustainable urban drainage system. The model consists of U-ditch channel, reservoir, an infiltration well. The bottom of U-ditch channel completed with a number of holes to make it porous. The channel filled with aggregate to filter the runoff from the road before flow down into the reservoir beneath. The water is then discharged to infiltration well. The model was developed based on rainfall data and other physical characteristics in Ambarawa City, Semarang Regency, Central Java.The channel dimensions and the depth of aggregate filter were designed base on runoff volume. The relationship among rainfall, runoff volume, area ratio, and drainage dimension are obtained. The results concept of sustainable road drainage is obtained in addressing the quality and quantity of rainwater.

Flooded Areas

Flooding of Municipal areas is a frequent environmental occurrence in Rivers State that occurs when rainfall runoff meets land surfaces with low water absorbing capacity or when it overwhelms drainage channels. In order to assess the flood situation in the study area, an integrated method which involves Field-measurement, Geographic information system (GIS), Laboratory analysis of soil samples and topographic studies were employed. Digital Elevation Model of the study area reveals that the flooded areas are situated in areas with elevations lower than its surrounding, thereby acting as a natural basin to retain flood waters after rainfall. Four holes were drilled to depth of 3m to obtain soil samples at 1 m sampling interval, from which laboratory analysis was carried out to determine some geotechnical parameters such as soil’s particle size, specific gravity, bulk density, porosity, moisture content, permeability and hydraulic conductivity. Results from the analysis show that permeability, hydraulic conductivity and porosity diminishes with respect to depth. The soil in the flooded areas have high fines content (silt and clay), high bulk density which increase with depth and a specific gravity that is typical of organic rich soils that contain sand mixed with a considerable amount of fines. At Nkpolu, mean permeability rates of 0.003cm/sec, 0.009cm/sec and 0.033cm/sec were obtained at 1, 2 and 3m respectively. At Eneka, mean permeability rates of 0.011cm/sec, 0.018cm/sec and 0.014cm/sec were obtained at 1, 2 and 3m respectively, while at Rukpokwu, mean Permeability rates of 0.021cm/sec was obtained at 1m, while 0.006cm/sec was obtained at 2 and 3m respectively. The Mean hydraulic conductivity for the locations under study is of the order of 10-4ft/day. This study has shown that the flooded areas are located in low lying urban areas which act as basins, therefore, the top soil is crusted with highly compacted soil horizons beneath. With high and frequent rainfall in the region which generates a lot of runoff, in addition to poor drainage system, flooding of the study area occurs frequently. Therefore, construction and maintenance of efficient drainage channels for an effective solution to urban pluvial flooding in the study area are thereby recommended.

Housing Complex

The area of the campus of Institut Teknologi Sepuluh Nopember (ITS) and its housing complex are usually inundated during heavy rain. It is because the slope of the land in the campus generally flat. Moreover, it is because some of the drainage channels contain sediment that reduce the optimum capacity of the channels. Hence, an evaluation of the drainage system of ITS needs to be conducted.  The steps of doing this evaluation are (i) identification of the existing problems, (ii) collection of primary and secondary data, (iii)  literature review, (iv) calculation of capacity of the existing channels, (v) calculation of runoff, and (vi) analysis of the existing retention ponds. The primary data includes flow direction, the slope of channels, dimension of channels, and thickness of sediment in the channels. The secondary data comprises of rainfall intensity, Master Plan of ITS, and land-use. The calculation includes engineering design, bill of quantity (BOQ), and budget. A standard operation procedure for maintenance of drainage system to make the channels optimum is also suggested. From the analysis, it is shown that the maximum daily rainfalls are 136.09 mm/day for 5 year-rainfall return period and 159.19 mm/day for 10 year-rainfall return period. The cause of inundation in ITS is there are some channels which are not connected to each other. As a result, the drainage water cannot flow easily to receiving water body (river). Another cause of inundation is the slope of some channels that does not properly made. The inundation of some roads is because there are no street inlets such that the water could not flow to the side channels. It can be concluded that (i) it needs some addition of secondary channels and box culvert in some areas, (ii) the slope of some channels need to be rearranged, (iii) 288 street inlets must be constructed along the planning area.

A <em>community garden</em> (CG) can generally be defined as a piece of land gardened collectively by a group of people that grow their produce on shared lots that have been divided into smaller plots. Some gardens are grown collectively, are divided into different plots for individual and family use; CGs are usually located in urban or peri-urban areas. As a growing portion of the urban open space network, CGs are contributing to land preservation, access to open space, and sustainable re-use of vacant land. They promote healthy communities and provide food security for many. In this context, the object of the study are the <em>municipal community gardens</em> (MCGs), a specific typology of CGs provided for land-use planning legislation and practice as an <em>urban service</em> with social function, made available to the community by the municipalities and assigned to be cultivated to citizens (usually seniors/retired people). In particular, the study aimed: i) to evaluate the presence of MCGs in the <em>città metropolitana di Milano</em> (the former province of Milano); and ii) to define criteria for new MCGs settlement, using existing geo-database and geographical information system to make it replicable in other settings. For the first topic the 133 municipalities of the former province of Milano (excluded the city of Milano) were analysed. Only 59 municipalities had presence of MCGs. The average area per capita of MCGs is 0.68 sq.m/inhab. (if we exclude Rodano, an outlier with 35 sq.m/inhab.). An overlay with land use map has permitted to define the relationships between the MCGs and their surrounding territory. The major part of MCGs are included in urban or suburban areas. For the second goal, the land area to be allocated for new MCGs was assessed for each municipality, comparing area of existing MCGs and a <em>minimum required area</em> (calculated on the basis of the inhabitants number). Finally a method was proposed to locate the new MCGs areas. Criteria used to identify suitable areas for new MCGs were: proximity to the road network inside residential areas, suitable land use, not high land capability. In this way it has been defined for each municipality the number of MCGs to be realized and their area, and located the potentially suitable sites. Choosing between the identified suitable areas, the new MCGs were homogeneously located on the territory of each municipality in order to ensure adequate coverage of residential areas; the degree of coverage has been verified through a <em>service area</em> analysis. The proposed method seems to be useful for the MCGs settlement at metropolitan/provincial level.

Urban Flood

In recent decades, Malaysia has become one of the world’s most urbanized nations, causing severe flash flooding. Urbanization should meet the population’s needs by increasing the development of paved areas, which has significantly changed the catchment’s hydrological and hydraulic characteristics. Therefore, the frequency of flash flooding in Malaysia’s urban areas has grown year after year. Numerous techniques have been used, including the statistical approach, modeling, and storm design methods, in flood simulation. This research integrated hydrology and hydraulic models to simulate the urban flood events in the Aur River catchment. The primary objective is to determine water level and forecast peak flow based on hydrological assessment in the drainage system using XPSWMM software. The rainfall data for 60 min was used for this study in the hydrological analysis by obtaining an intensity-duration-frequency curve and peak flow value (Q peak). XPSWMM is used to simulate the response of a catchment to rainfall events in which runoff, water depth profile, and outflow hydrograph are obtained. Peak runoff is also obtained from the modified rational method for validation purposes. The proposed method was verified by comparing the result with the standard method. This is essential to identify flash flooding, which can lead to efficient flood mitigation planning and management in the urban catchment. The increase in residential areas results in the alteration of time of concentration, water quantity, and flow rate. Thus, to mitigate present and future problems, the effects of urbanization on water resources and flood should be analyzed.
