Description: Technical Note
Purpose: The purpose of this document is to provide guidance on the use of two computer-based calibration functionalities recently developed for the Gridded Surface Subsurface Hydrologic Analysis (GSSHA) model. These new capabilities enable the incorporation of soft data, or prior information (i.e., extra observations which pertain directly to the estimable parameters, primarily in attempts to stabilize the calibration process). These new calibration methods are not only efficient (measured in terms of forward-model, call-run requirements) but also effective in that they result in physically acceptable models usable for subsequent prediction. This document describes how to use these new functionalities to calibrate a GSSHA model as well as benefits that can be derived in the process.
