| dc.description.abstract | Urban flash flood is a result of storm water increase which is a usually the result of urban land allotment changes done with development projects. The present work is to identify individual data layers that affect stormwater generation,then make changes and incorporate such changes to the existing data. This tool further provides graphical representation of stormwater changes and then allows incorporation of a detention pit. The determination of pit size is dynamic and the graphical comparisons show the influence of detention. The tool allows tooptimize the pit size to compensate the storm runoff increment due to land modifications. This GIS enabled land management tool with on-screen capability was tested for user-friendliness, accuracy, efficiency and use by non-technical land managers. | en_US |
