Floods in Jakarta showed that the Ciliwung watershed and surrounding areas in critical condition. More than 50 % of land cover Ciliwung watershed is residential. Planting trees in residential areas have been insufficient to infiltrate as much water into the ground. Infiltration well is one possibility for absorbing water in residential areas. The purpose of this study was to determine the variation in the level of water absorption Ciliwung watershed and surrounding areas. The method used is overlaying analysis of the factors that determine the rate of water infiltration with geographic information system. Each of these factors gave weights and scores to obtained variations Ciliwung water infiltration rate. The results showed that the regions with the highest levels found in the upper catchment area and the city of Bogor, middle absorbtion water area was in Bogor Regency, low water absorption areas in Depok , South Jakarta , and East Jakarta . While in North Jakarta, Central Jakarta and West Jakarta the water absortion is very low level due to the shallow ground water level and very low soil permeability. Map variations in water absorption can be used as a material consideration for determining the locations of recharge wells effectively.

Porosity And Permeability

During rapid urbanization, it is necessary to increase soil permeability and soil porosity for reducing urban runoff and waterlogging risk. Woody plants are known to increase soil porosity and preferential flow in soil via living roots growth and dead roots decay. However, the primary results of dead woody plant roots on soil porosity and permeability have been discussed based only on the hypotheses or assumptions of different researchers. In this study, living and dead roots (decayed under natural conditions for more than 5 years) of Gansu poplar trees (Populus gansuensis) were selected. They were selected to compare the influence between living and dead roots on water infiltration rate and soil porosity in a cylindrical container (diameter = 20 cm, height = 66 cm) under laboratory conditions. Results indicated that the steady-state water fluxes at the bottom of the containers without roots (control), with living roots, and with dead roots were 54.75 ± 0.80, 61.31 ± 0.61, and 55.97 ± 0.59 cm d−1, respectively. Both living roots and dead roots increased the water infiltration rates in soil and also increased the water storage capacity of soil. The water storage capacities of soil without roots, with living roots, and with dead roots were 0.279, 0.317, and 0.322 cm3 cm−3, respectively. The results from SEM indicated that smaller pores (30–50 μm) were in living roots and larger pores (100–1000 μm) were in dead roots. The soil permeability was increased by living roots possibly due to the larger channels generated on the surface of the roots; however, water absorbed into the dead roots resulted in greater water storage capacity.

The development of the city is very fast. Various socio-economic activities grow in line with the development of various human needs. The need for land to accommodate these various activities is difficult to avoid, so the city seems to be competing to build and consume the existing land. This condition has an impact on decreasing water absorption, thus threatening various disasters such as floods, the destruction of biodiversity, and drought, of course, the scarcity of clean water. Facing this phenomenon, the research examines the extent to which land use changes affect the level of water infiltration by calculating changes in the conservation index. This study takes the case in Arjawinangun Sub District. The selection of this location is solely due to the availability of data and the spatial plan that is currently being prepared whether it can become one of the parameters for changes in land use in the future.

The need to settle is a basic need of people that must be fulfilled. The weakness of law enforcement and public awareness on the spatial planning implicate the emergence of settlement areas in various locations that are less suitable for its allocation. The settlements in Semarang are growing very fast and tending to be unfocused. The increase of built area especially in residential areas indicates reduced of green open space and the catchment area. This phenomenon begins to appear in the outskirts of Semarang. This study aims to examine the development of settlements that occurred during the period of 10 years in the outskirts of the city of Semarang. It includes 10 districts, further, this study used descriptive quantitative and spatial analysis. The results showed that the completeness of the factor is the most influential factor on the development of settlements. Settlements tend to develop regularly with a regular pattern. The residential development areas also occur in the catchment area and in locations that are not suitable for allotment, so that limitation efforts should be made on the development of settlements. There are still some locations that are possible for the construction of settlements in the outskirts of Semarang. The government needs to follow up this issue by providing information to the community, so that the development of settlement is in accordance with the direction of urban development

Models of digital elevation (DEMs), which provide elevation information for the ground surface of the catchment, are core components of computer-based analyzes for drainage basins. Many production methods are available, including contour interpolation, DGPS (Differential Global Positioning System) interpolation, and digital photogrammetry techniques. However, data on the precision and often contradictory nature of these three techniques are sparse. This study aims at identifying some of the contributing factors and comparing the accuracy of various approaches quantitatively. Changes in land coverage break ecosystem cycles, which may directly affect land ability to sustain human activity resulting in long-term trends of decline and inter-annual variability. It can be monitored at a spatial level of detail to enable the study of human-induced changes. Remote sensing techniques (RS) and geographical information system (GIS) methods have been used to extract the spatial and temporal changes of urban land use in the city of Al-Kut. The land sat satellite images taken in periods encompassing 1997, 2007, and 2017 are used. As a result, the city has lost a large part of its urban specificity and gained randomness and disorder in most of its residential neighborhoods, which was especially exacerbated after the change in the governing system in 2003. The results show an increase of 314% and 219% in industrial and residential areas, respectively, whereas agricultural land and open spaces have decreased by 66 % and 32%. The data analysis reveals a diagnostic relationship between land-use conversion and socio-economic drivers. This research sheds light on the total area changes of the Al-Kut city before and after 2003. It highlights the significant destruction of the city life, which was established over almost three centuries.

In the present article the assumption that the design of the soil-like artificial body in zero-moment of existence determines the dynamics and trajectory of soilforming process was tasted. It was shown that an important aspect of the experiment is the search criteria that you can perform evaluation of the functional properties of the generated structures depending on their organization. The study of the water infiltration dynamics from the soil surface is highlyinformative non-destructive testing for evaluating the properties of the soil body. Studies showed that technosols as artificial creation have fundamental differences between the natural soils for which the classic Philip equitation was proposed. Technosoils are porous, but heterogeneous formations. The process of filtering in technosols is not laminar, periods of smooth water infiltration is outbreak by disastrous water absorption. To simulate this process it was showed that the better results may be obtained due to originally modified Philip equitation. Specific constant C describes the dynamics of the infiltration process the early stages of the experiment and is a specific indicator for technosols. In natural soils this constant is zero. The sorptivity of the pedozems was reveled to be depended from the underlying layer. Organic components contribute to the formation of aggregate most of which is water resistant. Such for- mations smooth density variation of clay soil resulting from swelling and shrinkage processes that can maintain stable structure of the pore space. As a result, the soil after phytomeliorative rotation gets such features as reduced infiltration rate, but increased level of filtration. The artificial mixture of clay has significant waterproof properties, which ultimately can lead to complete discontinuance of water absorption by technosols. Waterproof properties of soil may increase the risk of water erosion of technosols. For technosoils structural change of the pore space state are inherent in contact with water because hydrolabile units of their structure. Accordingly, during the infiltration process there are significant changes in the course of the rate of filtration of water.

Environmental problems in Jakarta, especially flooding problem, is strongly influenced by the condition of eight watersheds that flow into Jakarta Bay, namely Bekasi, Cisadane, Angke Pesanggrahan, Ciliwung, Krukut, Cakung, Buaran and Sunter. The center-periphery relationship between Jakarta and surrounding areas triggered significant land use changes in the watershed, especially in the upstream area. This study aims to analyze land use changes in eight watersheds that flow into Jakarta Bay in 2000, 2009 and 2017 as well as their effect on the distribution of the criticality level of the catchment area, using Geographic Information System (GIS) refers to Planning Procedures for Forest and Land Rehabilitation Engineering Watershed. The criticality map of the catchment area was created by overlay and scoring slope infiltration map, soil infiltration map and rainfall infiltration map. The results showed that there was a significant increase in built-up area of 14,33% in 2000-2009 and 10,42% in 2009-2017. In contrast, the area of dry land farming decreased significantly by 12,99% in 2000-2009 and 5.96% in 2009-2017. Based on the criticality analysis of the catchment area, land use changes in study area, mainly due to urban growth, has a significant effect on the criticality level of the catchment area.

Snatch theft incidents are on the rise in Malaysia especially in the cities. It tends to happen in cities because there is a possibility to commit it and both crime and urban are often associated with each other. The aim of this paper is to find out whether the building with two or more levels in urban area contributes to the snatch theft incidents. The present study has been taken up to detect the hotspots of snatch theft in Selangor, Malaysia. The crime data were obtained by requesting and analysing the index crime statistical data from the Royal Malaysian Police (RMP). This study made use of the Geographical Information System (GIS) where its 3D modelling function to construct, assess and analyse the area with high snatch theft cases. The crime reports of 2010 until 2015 were geocoded and the crime maps were prepared in ArcGIS 10.2. It was found that the hotspot area is a mix-used development area which consists mainly of commercial and residential areas of more than two-level buildings.

Abstract The aim of the study is to find the relationship between the land surface temperature and air temperature and to determine the hot spots in the urban area of Bucharest, the capital of Romania. The analysis was based on images from both moderate-resolution imaging spectroradiometer (MODIS), located on both Terra and Aqua platforms, as well as on data recorded by the four automatic weather stations existing in the endowment of The National Air Quality Monitoring Network, from the summer of 2017. Correlation coefficients between land surface temperature and air temperature were higher at night (0.8-0.87) and slightly lower during the day (0.71-0.77). After the validation of satellite data with in-situ temperature measurements, the hot spots in the metropolitan area of Bucharest were identified using Getis-Ord spatial statistics analysis. It has been achieved that the “very hot” areas are grouped in the center of the city and along the main traffic streets and dense residential areas. During the day the "very hot spots” represent 33.2% of the city's surface, and during the night 31.6%. The area where the mentioned spots persist, falls into the "very hot spot" category both day and night, it represents 27.1% of the city’s surface and it is mainly represented by the city center.
