Purpose and Scope: The principal objective of this project was to measure the backwater and discharge distribution for multiple bridges. These data have been used to determine if the methods developed by Schneider and others (1976) for single-opening highway crossings could be applied to multiple bridges. In addition, the method developed by Tracey and Carter (1955) and Cragwall (1958) was modified to use the procedure proposed by Schneider and others (1976) to calculate friction losses in the approach reach. This modified procedure was then also tested.

From abstract: This report is the third in a series of reports describing the regional geohydrology of the northern Louisiana salt-dome basin. The Wilcox-Carrizo and Sparta aquifers are the principal Tertiary aquifers of regional extent in the basin. The Wilcox-Carrizo aquifer is not affected by regional water-level declines, as no large pumping centers have been developed. Water-level fluctuations in wells are mostly seasonal. As shown by the hydrographs of seven wells, the seasonal fluctuations are generally less than 10 feet annually. Therefore, the potentiometric surface of the Wilcox-Carrizo aquifer in northwestern Louisiana is shown by contours using data collected from 1960-80.

From abstract: This report, which describes the hydraulic characteristics of the Wilcox-Carrizo aquifer, is the fourth in a series of reports describing the regional geohydrology of the northern Louisiana salt-dome basin.

From purpose and scope: The purposes of the investigation were to develop from available information (1) a description of the regional aquifer system serving as a public supply in the Capital Area Ground Water Conservation Commission district, the Florida Parishes of southwestern Mississippi; and (2) to discuss potential alternative sources of freshwater.

Abstract: "A geologic reconnaissance map was prepared in the area of Vacherie Dome at a scale of 1:24,000. To do this, the available data were compiled, resistivity surveys were conducted, and reconnaissance field mapping took place. Then all the information was consolidated for the map preparation."
