A STOCHASTIC-MODEL OF RIVER WATER-QUALITY - APPLICATION TO SALINITY IN THE COLORADO RIVER

This research combines mass transport theory with stochastic methods t o derive a stochastic, variable flow, surface water quality model for water quality policy analysis. Steady-state flow assumptions and a ser ies of differential equations reduce the information and number of equ ations required to completely specify the model. The newly developed h ydrology model is applied to river salinity in the Colorado Basin to e valuate the effectiveness of alternative salt load reduction strategie s in water quality management. Model results are used to illustrate th e influence of salt load reduction, stochastic river flows, and water conservation on river water quality.
