CHAPTER 5

THE COLORADO RIVER BASIN MODEL

5.1 Introduction

The Colorado River Basin Model was constructed using the sub-

models developed in Chapters 2 through 4 as its major elements. The

completed model is of a form that can be used in simulation studies

in the manner outlined in Section 1.3. Each operation and relation-

ship is coded for use on a digital computer, operations being modular-

ized as subroutines for efficiency of computation and to facilitate

modification.

Submodels corresponding to streamflow generation, stream salinity

generation, and reservoir modeling have been validated as described

in Chapters 2, 3, and 4 respectively to insure reproduction of the

major characteristics of the actual river system. Validation of the

complete basin model was performed to ensure that the mass balance of

water and total dissolved salts would be maintained over the portion

of the river system modeled.

The conceptual structure of the river basin model is presented

in Section 5.2. Validation of the river basin model is discussed

in Section 5.3, and a summary of program inputs is included in Section
