CALIBRATION

Abstract

This appendix describes the methods and major assumptions used to calibrate the hydrologic inflows, agricultural return flows, and agricultural water demands in CALVIN for the Central Valley. Results of the calibration are presented. The objective of calibration is to integrate surface and groundwater hydrologies developed for DWRSIM and CVGSM and reconcile inconsistent assumptions in these two separate hydrologies, as well as reconcile agricultural water demand assumptions with water deliveries in the CVPIA-PEIS (USBR 1997). This is a physical calibration of the mass of water in the Central Valley’s interconnected surface and groundwater system.
