Flow Direction from Land Surface - Parker and Ipswich Watersheds - ASCII Raster File

This datalayer is a gridded flow direction (i.e. river network) of the watersheds draining to Plum Island Sound. The resolution is 120 m x 120 m. This layer gives the direction of each cell to the next downstream grid cell. The gridded river network is used to explore scientific questions regarding the role of different land uses in defining nutrient loading, and the role of river systems in controlling exports to the coastal zone. Provide the flow direction of materials from source areas on land to downstream aquatic systems for general mapping and display, nutrient loading and routing analysis, and aquatic ecosystem modeling.
