BRIEF DESCRIPTION OF DATA 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.
