From abstract: Prototype tests were conducted to comprehensively evaluate the performance of the 84-ft-lift Bay Springs Lock. The evaluation included analysis of the operating characteristics and hydraulic efficiency of the lock as well as a comparison of the physical and analytical model results with the prototype.

From abstract: The Jackson gas field, in Hinds and Rankin Counties, Miss., is in the eastern Gulf Coastal Plain, about 160 miles north of New Orleans and 40 miles, east of the Mississippi River at Vicksburg. The gas is produced from a Cretaceous chalk from 2,088 to 2,236 feet below sea level. Overlying the chalk is the regular sequence of Tertiary rocks found in Mississippi. On the crest of the anticline in the city of Jackson the Cockfield formation of the Claiborne group is exposed, surrounded by the Jackson formation. Some Forest Hill sand of the Vicksburg group is exposed in the northwestern part of the area described. Overlapping these formations are Pliocene and Pleistocene terrace and alluvial deposits, and the entire area is covered by a blanket of less of varying thickness.

This Final Synthesis Report summarizes a four-year program to characterize and monitor carbonate mounds on the Mississippi/Alabama outer continental shelf.

From abstract: This report evaluates "four dam-break flood-wave models [...] by using three field data sets and selected criteria of desirable features." It includes maps, graphs, and tables.

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.

From introduction: A large amount of information is available on the aquifers of Mississippi. Reports resulting from various areal studies have described the ground-water resources of the areas concerned, but no reports dealing specifically with statewide occurrence of individual aquifer systems have been prepared previously. A series of "aquifer atlases" was deemed the most effective way to point out the character, the potential, and the extent of development of the aquifers and thereby provide water managers with data needed for efficient utilization of available resources. This report on Miocene aquifer system is the first in the series.

From introduction: This report shows changes in water levels and water-level altitudes in an area where large quantities of ground water are withdrawn for irrigating rice and other crops, aquaculture, and industrial use.

From purpose and scope: The purpose of this study are to derive base flow estimates for representative parts of the Cretaceous and Tertiary clastic outcrop area as an aid in estimating recharge to the sand aquifers; to use base flow relations to estimate aquifer hydraulic parameters; and to relate the lithology of the aquifer to the streamflow duration curves.

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 purpose and scope: This report describes geohydrologic conditions in the Mississippi salt-dome basin in the area of the Cypress Creek and Richton salt domes. It incorporates data from the area characterization investigations in Mississippi and provides a foundation of technical information for subsequent, more detailed hydrologic investigations.

From introduction: This report shows the altitude of ground-water levels and changes in water-levels in the Delta where large quantities of ground water are withdrawn for irrigating rice and other crops, aquaculture and industrial use.

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.

From introduction: In this study on raw material sources of uranium the Southern Interstate Nuclear Board has catalogued all known occurrences of uranium and some references to thorium in a 17-state area (P1. 1). These occurrences have been evaluated as potential sources of uranium by the State Geological Surveys and the consultant group of SINB. Favorability guides have been applied to the known occurrences and recommendations have been made for future action by the states involved, federal agencies, or by industry. State recommendations are included in state-by-state summaries. The state reports were written either by personnel of the State Geological Surveys or were abstracted from State geological survey data by members of the consultant group...The purpose of this study was to compile information on and systematically assess uranium and other radioactive occurrences in the region. The SINB undertook the project because of its statutory, interstate capability as an extension of government in each of the 17 states, an arrangement that lends itself effectively to this cooperative undertaking.

Ground-water and surface-water samples collected in the vicinity of Tatum salt dome, Mississippi, a U.S. Atomic Energy Commission project test site, has been analyzed by the U.S. Geological Survey as part of the evaluation program after the Salmon Event. Samples were collected from wells of all types of construction and at distances of 1 to 5 miles from the dome.
