| dc.description.abstract | The flood hydrograph estimation in a
catchment is a significant parameter for water
resources and conservation of water. Recently, the
Geographic Information System (GIS) has become
an efficient tool obtaining the watershed’s
physiographical and hydrological parameters.
This work presents a sensitivity analysis used
as test for the comparison between hydrological
studies prepared using the common practice
(watershed parameters calculated by hand) and
the GIS integration as a newer practice in the
water resources industry in tropical regions. The
GIS model used was ESRI ArcMap, the ArcHydro
tools and HEC-GeoHMS extensions, to determine
the hydrologic parameters used in HEC-HMS
model.
The investigation have proven that the use of
GIS and the hydrologic tools improve the
calculations of the Area and Curve Number
parameters; in the case of the Lag time many
factors influences the formula selection including
the analyst expertise and historical equation
selection.
