Objective:

Based on investigations and research in the past 5 years, climatologists believe that multidecadal periods of warming and cooling of the North Atlantic Ocean’s surface waters ultimately affect precipitation patterns across much of the United States. Since river flows are largely rainfall dependent, variation in rainfall should result in variations in river flow to coastal areas, as well. Flow increases in the northern part of Florida and flow decreases in peninsular Florida are consistent with the Atlantic Multidecadal Oscillation (AMO) and the reported relationship with rainfall. These relationships extend not only to rivers in Florida but to the entire southeastern United States, both Atlantic and Gulf coastal rivers. Although spatially explicit data layers commonly used in hydrologic models are readily available, accessibility of meteorological data with adequate spatial and temporal coverage remains a challenge. The ability to predict streamflow accurately with a model, for example, can be strongly impacted by the input data. The goal of this study is to determine sensitivity of the SWAT (Soil and Water Assessment Tool) model to the use of measured, local versus simulated meteorological data for a given resolution of soils, land-use (LU), and Digital Elevation Models (DEMs) required by the model.
