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.

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

<p class="1Body">The study is aimed at examining the vulnerability of some residential neighbourhoods in Calabar to the menace of flooding with a view to determining residential areas of high, medium and low flood risk. Two hypotheses were formulated such as: there is no significant relationship between the magnitude of flood, and the vulnerability of residential neighbourhoods and the elements-at-risk to flood in residential neighbourhoods in Calabar do not vary significantly according to the topography of the area. The major primary data were obtained from the metric measurement of the coverage of flood and the assessment of the numerical value of the residential buildings considered vulnerable to flood within the areas measured. Secondary data were also obtained from the collection of both published and unpublished materials and data on flooded buildings and displaced persons were also obtained from the State Emergency Management Agency (SEMA), Calabar. The data were analyzed using descriptive statistics and hypotheses tested using the regression coefficient of the least square method and scatter grams for prediction. The results of the hypotheses were found to be significant as the magnitude of flood determined the vulnerability of some residential neighbourhoods. Vulnerability was found to be higher in low lying residential neighbourhoods. The study, however, recommends among others, planned and autonomous adaptation responses, flood plain zoning to urban agriculture, landscaping and recreational uses. Proper channelization of Calabar urban drainage system, stringent flood control legislation, and development control measures should be enforced so as to discourage people from building on or near flood-prone areas of Calabar.</p>

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. Dari evaluasi menggunakan software SWMM, pada kala ulang 1 tahun didapatkan 3 node lokasi banjir, kala ulang 2 tahun didapatkan 10 node lokasi banjir, kala ulang 5 tahun didapatkan 18 node lokasi banjir dan kala ulang 10 tahun didapatkan 19 node lokasi banjir.Kata kunci: SWMM, Banjir, Drainase, Evaluasi

Liquefaction is a condition of continuous soil mass deformation at residual stress due to increasing pore water pressure that results in effective stress reduced. This study was conducted to identify the potential hazards of liquefaction in the Jondul Rawang area in Padang City. This study is to observe the soil contour and characteristics. Primary data obtained by observing the soil contour, soil characteristics, and the form of buildings, etc. Whilst, secondary data obtained from the related documents as supporting data. The results concluded that the Jondul Rawang area is potentially liquefaction area where the soil contours and characteristics could be classified as peat soil and lied in the swamps. Furthermore, if the rainfall intensity increase then flooding occurred. Then as consequences, there were many residential houses and other buildings around the area turning into tilted and drowned due to the degradation of soil bearing capacity. Therefore, requiring disaster management efforts against the threat of liquefaction in that area, both in terms of the drainage system due to flooding and overall repairs for the sewerage could work well.

The City

Cimahi is one of the cities which participated in the Accelerated Habitat Sanitation Development Program in 2011 due to its poor sanitation conditions. The city experienced high flooding in 2018 as observed in the 36.4 hectares or approximately 0.76% of the total area affected even though its drainage system was discovered to be covering 89.87% in 2015. There are also several reports of displacement of residents and significant financial loss in the city due to flooding in the past decade and this means urgent attention needs to be provided to improve the condition of the city. Therefore, this study was conducted to calculate the level of risk from the drainage sector in each urban village of Cimahi City. This involves using scores ranging from 1 – 4, with a score of 1 indicating very low risk while 4 represents very high risk based on exposure factors such as percentage of inundation area, sanitation risk index (IRS) score, and the opinions of local government as well as impact factors such as population, population density, poverty rate, and urban/rural function. The research made use of both primary and secondary data with the primary data obtained through interviews with the population in the study area and local government representatives while secondary data were obtained from different institutions. The results showed 7 out of the 16 urban villages in Cimahi City are in Risk Category 1, 5 in Category 2, 1 in Category 3, and the remaining 2 in Category 4. This information with the risk category map for each village is expected to be used by the local government of Cimahi to analyze the flood-related problems better and create more effective solutions.

Saint Martin’s island is one of the unique coral islands and popular tourist destinations in Bangladesh due to its location and favourable environmental condition. The present study has been taken to know the present and past land use pattern, and to explore the existing drainage system and wastes management of Saint Martin’s island in Bangladesh. To achieve the goals of the study, both primary and secondary data have been collected and incorporated. Primary data have been collected through field observation, questionnaire survey, and focus group discussion (FGD). Total 200 questionnaires have been conducted by random sampling during summer and winter season in the year of 2015. Secondary data were also collected from various official records and related researchers’ publications and articles. It is observed from the study that land use pattern of Saint Martin’s island has already been changed and still changing randomly due to increase of inhabitants, settlers and tourists. Most of the agricultural land and vacant lands are going to turn into the hotels, resorts and other human settlements. There is no structural drainage system in this Island. Moreover, most of the wastes are going to be produced by the tourists, fishermen, hotels and restaurants. The present study suggested taking necessary initiate through solving the waste mismanagement problem and proper drainage system for this unique coral island.
