Spatial Hydrological Analysis on storm water harvesting investigation for sustainable water resources management strategy

Abstract The water issue has become a frontier of public debate globally due to awareness sustainable development. Nigeria's resources are under serious threat from inadequate catchment management that includes widespread pollution indiscriminate waste disposal. Stormwater is now recognized as valuable resource rather than nuisance, especially in large urban centers. Growing demand for exerted pressure on groundwater via dug well and boreholes scattered virtually every dwelling Nigeria. This challenge motivated this investigation the feasibility harvesting stormwater purposes supplementing supply flash flood management. study aims at quantification harvestable identification potential capturing sites using Spatial Hydrological Analysis GIS model Synthetic Hydrograph. result indicated total 24-hr rainfall 161.3 Mm 3 three available eight depressions identified. volume good incentive incorporate storm overall
