What is Hydrologic Modeling?
Another name for hydrologic modeling is spatial hydrology, which is “the study of the earth’s waters and the transport of their constituents using the spatial data structures and functions of a geographic information system (Maidment, 1996 paragraph 2)”. New technology has opened the doors for various modeling techniques that can be used to advance our understandings of water resources assessment and management. Geographic Information Systems (GIS) has become a useful tool for integrating the spatial properties of water movement through the landscape. GIS is a “fundamental set of automated ideas and concepts rooted in over 2500 years of exploration and geographic research (Dobson, 1995) and designed to provide answers to questions based on mapped data, (DeMers, 1997, p.3)”. Integrating GIS with hydrologic models is now a popular method that allows performance evaluations of multi-objective water management strategies.
