13. ABSTRACT (Maximum 200 words)
Hydrologic models are currently used to understand the economic and ecological imacts of hydrologic processes. A new
hydrologic model entitled Object-GAWSER was designed using an object-oriented platform to provide new insights into
watershed hydrology. Object-GAWSER is a temperature index model that simulates upland watershed hydrology. Object-
GAWSER is different from other hydrologic models in that each one of its components can be easily studied to understand
its sensitivity to various inputs. First, this report will show how Object-GAWSER can be used to simulate the hydrologic
behavior of forested, agricultural, and suburban watersheds. Second, this report will describe how Object-GAWSER was
designed.
