"The objective [of this report] is to produce an inventory of those important ecological along the lower Mississippi River on which siting of major industrial facilities and land clearing operations could have an impact."

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.

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.

Abstract: The report summarizes progress on geologic and hydrologic research related to the disposal of radioactive wastes. The research is described according to whether it is related most directly to (1) high-level and transuranic wastes; (2) low-level wastes, or (3) uranium mill tailings. Included is research applicable to the identification and geohydrologic characterization of waste-disposal sites, to investigations of specific sites where wastes have been stored, and to studies of regions or environments where waste-disposal sites might be located. A significant part of the activity is concerned with techniques and methods for characterizing disposal sites and studies of geologic and hydrologic processes related to the transport and (or) retention of waste radionuclides.
