GIS and Water Resources Modeling: State-of-the-Art

Uzair M. Shamsi
1999 Journal of Water Management Modeling  
This chapter presents an overvie\v ofthe latest GIS and water resources modeling integration approaches and software. The objective of integration is to estimate physical input parameters of the computer models used in water resources modeling. The chapter presents the watershed GIS database development proce-dun~s and methods of integrating GIS and modeling. GIS and Modeling Integration Rapidly developing computer technology has continued to improve the modeling necessary for water resources

Each paran1eter can be digitized fi·om maps, aerial photographs, or satellite images and stored in "layers" on a computer. Each layer can then be easily combined for input into a hydrologic modeL The use of GIS, as aside benefit, provides water resources managers with an easily updated database for other planning activities not directly related to water resources (Jostenski, 1988) . Effective water resources management requires the linking of specialized computer modeling to the GIS. At present, GIS primarily offers front-end or back-end applications to existing hydrologic models. Front-end applications Shamsi, U.M. 1999. "GIS and Water Resources Modeling: State-of-the-Art."
