II. Theory and Calibration
II.1 - Model Computation Diagram

The CRiSP.1 model calculates changes in fish numbers as fish move through tributaries, reservoirs, and dams. This can be diagrammed in terms of a computational tree (Fig. 3). Shaded boxes represent fish entering the system and passing dams and reservoirs on a daily basis. Unshaded square boxes represent calculations for travel time and survival of fish through the system. Rounded boxes represent input data to the calculation modules.
