Description:
Abstract: Watershed boundaries with a miminum size of 35 sq km.
Purpose:
This data set was derived at the World Resources Institute for input to the Reefs at Risk sedimentation and pollution from watershed based sources threat analysis. Agriculture, though important to economic development and food security, is a source of increased sediment, nutrient, and pesticide runoff. Threats from sedimentation and pollution from inland sources were modeled for over 3,000 watersheds discharging into the Caribbean. The indicators developed by the Reefs at Risk in the Caribbean project enable detailed comparative analyses of threats on many scales. The Reefs at Risk indicators are a simplification of human activities and complex natural processes.

Process_Description:
For the Reefs at Risk analysis, watershed boundaries were developed for the region using a modified DEM (USGS HYDRO1K, 2000) for the entire caribbean region and US National Aeronautics and Space Agency (NASA), Shuttle Radar Topography Mission (SRTM), 2003 (90 m resolution for the eastern caribbean). At WRI the DEM was "filled" and rivers and lakes were "burned" as to improve the accuracy of the watersheds. Rivers are based on HYDRO1k rivers. This resulted in a data set of more than 2,700 watersheds with a minimum size of 35 km2.
