I. Introduction
This document describes the theory and calibration of the Columbia River Salmon Passage model (CRiSP.1). The model tracks the downstream migration and survival of juvenile salmon through the tributaries and dams of the Columbia and Snake Rivers to the estuary.
CRiSP.1 describes in detail the movement and survival of individual stocks of natural and hatchery-spawned juvenile salmonids through hundreds of miles of river and hydrosystem. Constructed from basic principles of fish ecology and river operation, CRiSP.1 provides a synthesis of current knowledge on how the Columbia/Snake river hydroelectric system interacts with the juvenile salmonid populations of the system. Biologists, managers and others interested in the river system can use this interactive tool to evaluate the effects of river operations on smolt survival. The model is used to predict the realtime in-season water quality and fish passage conditions through the Columbia and Snake River system. This information is provided on the web at www.cbr.washington.edu/crisprt/index.html.
There are two modes that CRiSP.1 can use: a Scenario Mode that illustrates the interactions of model variables, and a Monte Carlo Mode, which is stochastic, providing measures of variability and uncertainty in predicted passage survival. Between any two points in the river system, estimates of probability distributions for smolt survival and travel time can be determined for any stock.
The model's hydrological and ecological parameters and the hydrosystem and fish operations are calibrated from information available between 1954 and 1999. For additional information, also see the website www.cbr.washington.edu/crisp/crisp.html.
CRiSP.1 has advanced programming features including:
- graphical interface to access and change model variables and equations
- flexible data structure that allows expansion of the model while assuring backwards compatibility with earlier versions
- configurability to a different river without reprogramming
- online help system.
The model runs on Win32 operating systems (Windows95/98/NT/2000) and on Sun SPARCstations under the Solaris2 and X Windows graphical interfaces.
CRiSP.1 was developed at the University of Washington's School of Aquatic and Fishery Sciences under a contract from the Environment, Fish and Wildlife (formerly Fish and Wildlife Division), Bonneville Power Administration.
