Long-Term Shoreline Change of the Chandeleur Islands Barrier System, Louisiana: 1855 to 1989
The Chandeleur Islands are the largest barrier island system along the Mississippi River delta plain, and are characterized by low-profile, washover-dominated barriers that are rapidly...

Louisiana Cheniers: Clues to Mississippi Delta History
The cheniers of southern Louisiana have map differences, deeding differences, and granulometric differences that distinguish them from swash-built beach ridges and from dune ridges. Instead,...

Weaver Bottoms Backwater Rehabilitation
Navigation channel dredge material was used to construct closure structures and islands in lower pool 5 on the Upper Mississippi River in 1986. Primary objectives included aquatic habitat...

Bed Sediments Size Changes, Atchafalaya River
During low flows of 1989 and 1991, we collected bed sediment samples from the thalwegs of the Mississippi River from Cairo, Illinois, to Head of Passes and along the Atchafalaya River...

Bank Stability Analyses Versus Field Observations
The concept and process of stream bank stabilization design through the development and use of limiting stability curves for the comparison of existing bank height/angle combinations to...

Design and Performance of Emergency Spillway Channel Erosion Protection—Grenada Lake Dam, Grenada, Mississippi
Grenada Lake Dam located on the Yalobusha River in northeast Mississippi is part of the Mississippi River and Tributaries comprehensive plan for flood control. The 13,000-ft-long earthfill-type...

Turbulent Velocity Flutuations in Natural Rivers
The longitudinal and transverse components of flow velocity, as well as the normal and tangential stresses, must be expected to fluctuate with time and space when flow at a high Reynolds...

Sediment Transport Assessment in the Old River Control Area of the Lower Mississippi River (USA)

Management of a Continental Shelf Ecosystem
The ecological system of the Mississippi-Alabama continental shelf is highly diverse and productive and contains unique natural features worth preserving. This system is intimately bound...

Consolidation Settlement Potential in South Louisiana
Primary consolidation is an important cause of wetland loss in active and recently abandoned deltaic plains in south Louisiana. Argillaceous and organic facies are most subject to reduction...

Historical Shoreline Position Change for the Mainland Beach in Harrison County, Mississippi
Historical shoreline position change (1851/52 to 1986) associated with the mainland beach in Harrison County, Mississippi, are controlled by engineering activities associated with beach...

Federal Levee Effects on Flood Heights Near St. Louis
A physical model of the Middle Mississippi River was used to perform quantitative analyses of Federal levee effects on flood heights. Contrary to some opinions of the general public, these...

Priority Problems of the Barataria-Terrebonne Estuarine Complex
The Barataria-Terrebonne Estuarine Complex encompasses an area of approximately 3600 square miles within the Mississippi deltaic plain, and consists of system of water bodies and wetlands...

Effects of Agricultural Drainage on Water Quality in the Lower Mississippi Valley and Gulf Coastal Region
Sediment and nutrient (N, P, K) losses were measured from research plots with surface drainage only and from plots with both surface and subsurface drainage for all or part of the decade,...

A Semi-Discrete Element Approach to the River Ice Breakup and Jamming Process
A semi-discrete element approach was developed to simulate the whole river ice breakup and jamming process. In this approach, ice mass is treated as discrete elements, and the movement...

Seismic Rehabilitation of Sardis Dam
Extensive subsurface investigation of the embankment dam revealed the existence of a weak layer of silt and soft clay in the original topstratum clay underlaying the upstream shell of...

Scour Analysis for Bridges over Missouri and Mississippi Rivers
Engineering services are being provided for three bridge crossings, two over the Missouri River and the other over the Mississippi River. Scour consideration for the bridged waterways...

Characteristics of Waves and Drawdown Generated by Barge Traffic on the Upper Mississippi River System

Sediment Concentration Changes Caused by Barge Tows

ET from Shallow Groundwater Maintained by Controlled-Drainage/Subirrigation System
Soil-water management by maintaining a shallow groundwater level (watertable) via a dual purpose subdrainage-subirrigation system, is becoming popular in humid regions of the United States...
