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.
