Abstract
Applying GIS to Identify Effluent-Dominated Waters in California
Track: Water Resources
Author(s): Jonathan Pickus, William Samuels
This paper describes a GIS-based approach for identifying and characterizing the effluent-dominated waters (EDW) of California on a State-wide basis. This system integrates the geospatial and hydrographic characteristics of the NHD, PCS, NWIS, ERF1, IFD, and STORET databases into a single architecture and systematically evaluates the hydrology within each hydrologic unit (HUC). The system is designed to give State and federal resource managers a tool with which to isolate those streams where State-wide water quality standards and designated uses may be applied differently from streams where the predominant flow is from natural sources.
