The Demonstration and Validation of a Linked Watershed Riverine Modeling System for DOD Installations-Calleguas, California; Resource Conservation and Climate Change Projects, RC-201302, Version 2.00
Abstract
The objective of this project is to demonstrate and validate a linked watershed and riverine modeling system for the Calleguas Creek Watershed. The system helps land managers assess outcomes resulting from military activities; the system also supports installation sustainability through informed watershed management of water, water quality, contaminants, and land-use impacts. The modeling system was developed and enhanced from existing watershed and riverine models. Hydrological Simulation Program-Fortran (HSPF) was used to compute water flow, soil erosion/sedimentation, nutrients, and contaminant loadings, whereas the Hydrologic Engineering Centers-River Analysis System (HEC-RAS) was used to evaluate instream water quality and aquatic ecosystem responses from watersheds both within and outside an installation. HSPF simulates, for extended periods of time, the hydrologic, and associated water quality, processes on pervious and impervious land surfaces and in streams and well-mixed impoundments. Benefits can be derived from the ability of the linked modeling system to determine contaminant loads entering and leaving the installation. In certain locations, this information can be used to identify to what extent the installation is responsible for the impaired waters. In cases where mitigation is necessary, the system will help land managers better assess which scenarios will provide the most environmental benefits for the least financial cost.
