Recent sediment studies refute Glen Canyon Dam hypothesis Recent sediment studies refute Glen Canyon Dam hypothesis
Recent studies of sedimentology hydrology, and geomorphology indicate that releases from Glen Canyon Dam are continuing to erode sandbars and beaches in the Colorado River in Grand Canyon National Park, despite attempts to restore these resources. The current strategy for dam operations is based on the hypothesis that sand supplied by tributaries of the Colorado River downstream from the...

Subsurface controls on historical subsidence rates and associated wetland loss in southcentral Louisiana Subsurface controls on historical subsidence rates and associated wetland loss in southcentral Louisiana
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. Other researchers have...

Latest Quaternary stratigraphic framework of the Mississippi River delta region Latest Quaternary stratigraphic framework of the Mississippi River delta region
Previous researchers separated the uppermost Quaternary stratigraphy of the Mississippi River delta region into two major lithofacies. The stratigraphically lower of these, "substratum," primarily consists of coarse-grained sediment deposited within lowstand-incised stream valleys. Relatively finer-grained "topstratum" overlies substratum; above interfluves, topstratum directly overlies...

Sand resources, regional geology, and coastal processes for shoreline restoration: case study of Barataria shoreline, Louisiana Sand resources, regional geology, and coastal processes for shoreline restoration: case study of Barataria shoreline, Louisiana
The Louisiana barrier shoreline of Barataria Basin, which lies within the western Mississippi River delta, has undergone significant retreat during the past 100 years. The most practical restoration method to rebuild these shorelines is sand nourishment. Seismic and sonar interpretations verified with geologic samples (vibracores and borings) indicate that there are nine sand targets...

11 things a geologist thinks an engineer should know about carbonate beaches 11 things a geologist thinks an engineer should know about carbonate beaches
This is a review of the geological aspects of carbonate beaches that a geologist thinks may be useful for an engineer. Classical geologic problems of carbonate beaches, for example how ancient examples are recognized in rock sequences, are of little interest to engineers. Geologists not involved in engineering problems may find it difficult to know what an engineer should understand...

Design and performance of a horizontal mooring for upper-ocean research Design and performance of a horizontal mooring for upper-ocean research
This paper describes the design and performance of a two-dimensional moored array for sampling horizontal variability in the upper ocean. The mooring was deployed in Massachusetts Bay in a water depth of 84 m for the purpose of measuring the horizontal structure of internal waves. The mooring was instrumented with three acoustic current meters (ACMs) spaced along a 170-m horizontal cable...

Sediment-hosted contaminants and distribution patterns in the Mississippi and Atchafalaya River Deltas Sediment-hosted contaminants and distribution patterns in the Mississippi and Atchafalaya River Deltas
The Mississippi and Atchafalaya Rivers transport very large amounts of bedload and suspended sediments to the deltaic and coastal environments of the northern Gulf of Mexico. Absorbed onto these sediments are contaminants that may be detrimental to the environment. To adequately assess the impact of these contaminants it is first necessary to develop an understanding of sediment...
