Progress Summary:

During this reporting period, we conducted research on non-point source pollution modeling. This includes a pilot study in a small watershed and an extended study considering the entire Pensacola estuarine watershed. The aim was to simulate the generation and transport of pollutants in overland flow to waterways (and finally the receiving basin) by using the Agricultural Non-point Source Pollution Model (AGNPS). The pilot study was undertaken for a complete sub-basin (610 km² in size) within the Pensacola estuarine watershed. This model has three major output products: runoff, erosion, and total nitrogen . We validated the model with real measurements dated on September 25, 2002. We also tested the model performance at four different levels of spatial resolution, namely, 45 m, 60 m, 75 m, 90 m, and 105 m. This part of work has been very computationally intensive (30 m does not work; program crashed). We also considered different rainfall conditions—return periods (5, 10, 50 years). The pilot work was quite successful. Starting from late 2005, we have been extending the geographic dimension of non-point source pollution modeling into the entire Pensacola estuarine drainage area while considering several different watershed management scenarios. We also investigate the scale impacts upon non-point pollution modeling through the simulations undertaken at different levels of spatial resolution. This involves the use of a land cover transition model being loosely coupled with the AGNPS . We reported our preliminary work on non-point source pollution at the 102nd Annual Meeting of the Association of American Geographers on March 11, 2006, Chicago.

The special International Journal of Remote Sensing (IJRS) edition (see below) highlights the remote sensing and GIS research primarily conducted by investigators from the U.S. Environmental Protection Agency (EPA) Estuarine and Great Lakes (EaGLe) Research Program. Investigators from four major EaGLe centers and EPA headquarter have contributed to this issue. All papers collected in this issue were peer-reviewed using the established procedures and criteria by IJRS. IJRS is a leading international journal in remote sensing.
