Relationships between factors i.e. lineament, slope, groundwater depth, precipitation/runoff, recording of urban stormwater, land use/land cover, soil texture, and drainage density, were weighted based on their response to the presence of groundwater. High to low weights respectively showed greater or lower impact on groundwater potential. The integration of these factors with their potential weights was calculated by weighted overlay analysis in a GIS environment to determine potential groundwater zones. Surface runoff and infiltration rate are greatly dependent on the slope or gradient, which is also an important factor in the suitability of groundwater recharge, i.e. a higher slope would produce more runoff higher and less recharge. The slope in the study area ranged from 1 to 37%, according to the IMSD guidelines (NRSA, 1995), classified into 5 classes, i.e. 0 to 1.00% (near level), 1.01 at 4.00% (very gentle slope), 4.01 to 8.00% (gentle slope), 8.01-16.00% (steep) and >16% (moderately steep).

Get the original essay The slope class with a higher value is assigned a lower rank due to relatively high runoff, while the slope class with a higher value is assigned a lower rank due to relatively high runoff, while the slope class with a higher value is assigned a lower rank due to relatively high runoff, while the class having a lower value is assigned a higher rank due to a flat surface (Jhariya et al. 2016). Another contribution to evaluate the recharge property can be made by a detailed morphometric analysis of the drainage network. The density of the drainage network influences the recharge and movement of groundwater as well as the occurrence of major or minor lineaments, faults, fractures, joints, and also provides pathways for the movement of groundwater and is very important hydraulically because it is an important indicator of water. percolation rate (Kumar et al. 2007) Edet et al. 1998; Shaban et al. 2006). The denser the drainage network, the lower the recharge rate. The extraction and analysis of the drainage network was prepared using topographic maps, field data and satellite images. Drainage densities were calculated in each of the grid squares according to Murthy (Murthy 2000): Drainage density = LWS/AWS (3) Where, LWS = total length of streams in the watershed and AWS = area of the watershed. Thus, the drainage density map obtained reveals a density value ranging from 0 to 51.5 km/km2, reclassified into five categories namely < 2.00 km/km2 as very low, 2.01-10.00 km /km2 as low, 10.01-20.00 km/km2 as moderate. , 20.01-30.00 km/km2 as high drainage density and 30.01-51.5 km/km2 as very high drainage density. From a recharge perspective, more weight was assigned to regions with very low drainage densities, whereas low drainage densities indicate a high frequency of permeable surface streams of the area comparable to the drainage density high, i.e. impermeable ground surface/rock formation. Regarding groundwater occurrences, higher drainage density is linked to less water infiltration into the soil and produces higher runoff. The water table was collected from the Chittagong Water Supply and Sewerage Authority (CWASA), the static water level was obtained by subtracting the water depth elevation of different tube wells in 2016 and the map of groundwater depth was prepared. Then, the depth of..
