Regional to local coarse to fine scale global change impact study on flow

Stream flows are essential for maintaining healthy aquatic ecosystems and for supporting human water supply needs. Integrated modeling approaches assessing the impact of changes in climate, land use, and water withdrawals on stream flows and the subsequent impact of changes in flow regime on aquatic biota at multiple spatial scales are necessary to insure an adequate supply of water for humans and healthy river ecosystems. We compared streamflow predictions from a regional-scale hydrological model to those of several fine-scale SW models under a range of hypothetical climate change scenarios to determine the range of predicted streamflow responses to fixed climate perturbations.This spreadsheet contains the results of a study investigating the sensitivity of predicted discharge to changes in precipitation and temperature inputs for a coarse scale (WaSSI) and three fine scale (HSPF, SWAT, WaterFALL) hydrologic models at a single site (02347500, FLINT RIVER AT US 19, NEAR CARSONVILLE, GA) from 1981 to 1999. The objective of this study was to demonstrate the feasibility of using regional and local scale models to identify unique areas of concern and understand fine scale hydrologic dynamics under climate change. Descriptions of the models and results of the study are detailed in the final report.
