The Atchafalaya River Delta. Report 6. Interim Summary Report of Growth Predictions.
Abstract
The Atchafalaya River delta in Louisiana has grown dramatically. The importance of land growth for the Louisiana coast and concern for its possible impacts has led the Corps of Engineers to conduct an investigation to predict how the delta will evolve over the next 50 years and how that growth will affect flood control and navigation in the area. The investigation approach uses several analytical and numerical techniques applied separately to arrive at independent predictions of delta growth. The approach is arranged so as to provide results from increasingly sophisticated techniques over a period of 5 years; results of an extrapolation of past behavior, a generic analysis of similar deltas' growth patterns, and a quasi-two-dimensional model have been completed thus far. They show that the delta will expand to about 19 square miles by 1990 and 60 square miles by 2030. Flood stages at Morgan City and Calumet will increase by at least 0.5 to 1.0 ft by 2030. All results are very sensitive to the amount of subsidence that will occur.
