      Two regional releveling profiles and six tide gauges provide a basis for evaluating recent rates of delta plain subsidence in southcentral Louisiana. Analyses of these records demonstrate close correlations among highest historical rates of subsidence, rapid wetland losses, large volume hydrocarbon production, and probable reactivation of deep subsurface faults.   The disastrous combination of rising sea level and subsidence of the Mississippi Delta on which it is built suggest that it will succumb at some point in the future.

      A river delta is a landform created by deposition of sediment that is carried by a river as the flow leaves its mouth and enters slower-moving or stagnant water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or (more rarely) another river that cannot carry away the supplied size and shape of a delta is controlled by the balance between watershed. Deltas have a fairly flat section called a delta plain that is above water. The river cuts many small channels through the delta plain. These channels are called distributaries. New sections of delta build up at the mouths of the distributaries. The rest of the delta is under water. There is a steeply sloping delta front that faces the lake or.

      significant area of northern Mississippi was contained in this investigation, including the Mississippi Delta region, the preeminent agricultural area in the state. The study involved the sampling of 14 wells pumping from the shallow MRVA, widely used for irrigation and fish culture in the Delta, or various deeper Tertiary aquifers that provide.   There have been five main distributary systems of the Mississippi Delta in the past 5, years [Coleman, ]. Today, the Mississippi River distributary system splits into .
