Book excerpt: The diversion of fresh water and sediments from the Mississippi River to the Atchafalaya River is developing a new delta on the south-central Louisiana coast. The building of this new wetland area has prompted scientific interest in predicting delta evolution. This study reports the analytical prediction of future delta growth based on the theory of turbulent jets that issue from river outlets and discharge into quiescent bays. An integrated form of the hydrodynamics equations of flow continuity and momentum balance, coupled with the advection-diffusion mass transport equation, have been formulated into a two-dimensional spatial domain. Closed-form analytical solutions are obtained with the aid of similarity functions for the velocity and sediment concentration profiles. A numerical procedure for estimating the area and volume of deposition of the delta sediments is presented. The results show that the deposited sediment forms a saddle-shaped bottom. Rapid accumulatin of suspended sediment near the river outlet and an abrupt decline of sediment deposition away from the outlet observed. It is concluded that the riverine inflow has a insignificant influence of sediment deposition within a short longitudinal distance, and that beyond that distance the riverine inflow is insignificant. The analytical predictions are compared with the predictions made by other statistical and generic approaches; an agreement is found. A sensitivity analysis is performed to assess the relative imporatance of various parameters in the river-bay-delta system. (Author).

Book excerpt: The development of two freshwater deltas in Atchafalaya Bay is providing new subaerial land is south-central Louisiana in an area traditionally subjected to coastal retreat. From the engineering and scientific standpoints, it is important to know at what rate and by what mechanisms the deltas in Atchafalaya Bay will continue to grow. Utilizing maps, charts, aerial photographs, and published and unpublished literature, growth patterns in 10 similar deltas and subdeltas were examined as a means of projecting the rate of growth and configuration of subaerial land in Atchafalaya Bay to the year 2030.

This book was released on 1984 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: This report describes data collected for use in development and verification of numerical and physical models employed to predict the evolution of the Atchafalaya Bay Delta. Stemming from a data collection program in this area during 1980 through 1983, this report presents representative results. To make the data accessible for use by others and to provide a permanent record of the instrumentation and techniques is the purpose of this report in the series. Data collected were: tidal elevation, velocity-conductivity-temperature, and suspended sediment. (FR).
