ABSTRACT
Geographic
Information Systems (GIS) have been recognized as a powerful means to
integrate and analyze data from various sources in the context of
comprehensive watershed management. Hydrologic modeling plays a crucial
role, and there is much to gain in incorporating these modeling
capabilities in GIS. Interfacing between these models and GIS may be a
very efficient way of overcoming the difficulties and getting very good
results in terms of engineering practice. In this paper, GIS-aided
watershed modeling is applied in a watershed in northwest China. The
GIS is interfaced with a watershed modeling program, HSPF, to
facilitate data storage, management and display; derivation of model
input parameters; and effective presentation of results. Through
interfacing programs and other GIS programs, a database is queried to
derive model input parameters, and to visually present results in maps.
We simulated a rainfall process in the Shiyang River Basin in northwest
China. Results for current conditions and practices show that HSPF can
be used successfully in similar inland watersheds.
