A one-dimensional dynamic mathematical model was developed for computer solution of estuarine dispersion problems. The math model was based on the 1-dimensional mass transfer equation for the longitudinal distribution of a substance in a variable area estuary. Finite-difference approximations of the mass transfer equation were used to develop the numerical model. The 1st problem considered was the distribution of organic wastes in the Corpus Christi Harbor Channel. The goal of this study was to determine the effect of waste discharges on the organic loading in the Harbor Channel. Model results showed that wastes are adequately degraded in the channel and do not accumulate to excessive levels. These results were compared with field data obtained from sampling runs in the Harbor Channel. Design of a surface aeration system for Vince Bayou was the 2nd application of the math model. The results of this work showed that dispersion and dilution would greatly affect the oxygen transfer efficiency of a surface aeration system. Another conclusion was that tidal flows would have little influence on the efficiency of a surface aeration system operating on the Houston Ship Channel. The 1-dimensional dynamic mathematical model may be used effectively to solve such dispersion problems as considered here
