Abstract
Description
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 HECHMS
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.
