Processes Controlling the Retreat of the Isles Dernieres, A Louisiana Barrier-Island Chain
The Isles Dernieres is a low-lying, transgressive barrier-island chain situated about 150 km west of the modern Mississippi delta. Much of the Isles Dernieres consists of highly dissected...

Implications of Accelerated Sea-Level Rise on Louisiana Coastal Environments
Natural and human-induced processes have combined to produce high rates of relative sea-level rise and coastal land loss in Louisiana. This paper presents historical trends in sea-level...

Response of Lagoons to Sea Level Change
Relative sea level change and sediment accumulation rates are compared for 21 lagoons on the U.S. Atlantic and Gulf coasts to determine their accretionary status. The lagoons reviewed...

Effects of Sea Level Rise on the Mississippi River Delta Plain
Geologic studies of the Mississippi River delta plain and continental shelf reveal the occurrence of several relative sea level stillstands during the last stages of the Holocene transgression....

Residual Currents—The Variability of an Inlet Sediment Trapping Mechanism

Seacliff Retreat and Coarse Sediment Yields in Southern California
Seacliffs are erosional slopes. They form when a receding shoreline impinges on coastal terraces, hills, or mountains. Wave-caused erosion at the base of a seacliff controls its long-term...

Influence of Water-Level Variation on the Performance of Great Lakes Beach Nourishments
In an effort to evaluate the influence of Great Lakes water level change on beach nourishment profile adjustment, an extensive ten year monitoring study was conducted in southern Lake...

Integrated Photogrammetric and Geophysical Monitoring of Shoreline Instability in Littoral Cells in the Pacific Northwest, USA
Several factors have recently focused on the attention of government agencies, academic researchers, and the general public on coastal erosion and beach resource management in the Pacific...

Water Table Lysimeter Data Interpretation
Lysimeters were used to estimate seasonal water use of wet meadows and phreatophytes in northern Utah, southeast Idaho and southwest Wyoming (1983-1990). Twelve water table lysimeters...

Lysimeters Versus Buffer Areas Et and Agronomic Comparisons
Evapotranspiration (Et) from lysimeters may not represent Et of undisturbed, surrounding sites because of factors related to water, soils, plants, and even animal life. Et and agronomic...

Lysimeters to Study Soil Water Movement and Crop Water Use Under High Water Table Conditions
A system of 6 drainage lysimeters was constructed to conduct studies of water use and water movement in 3 different soils influenced by high water tables. The lysimeters were equipped...

Drainage Lysimeters for High Water Table Citrus Studies
Forty drainage lysimeters were installed in 1988 to conduct water quality and consumptive use studies for citrus. The lysimeters were designed to simulate the high water table conditions...

Herbicides in Streams: Midwestern United States
Results from a 2-year study of 149 streams geographically distributed across the corn-producing region of 10 midwestern States show that detectable concentrations of herbicides persist...

Multi-Purpose Subsurface Drainage System for the Town of Saguache
The town of Saguache, Colorado had a high water table during the irrigation season that caused numerous problems within the town and resulted in high infiltration rates to the sewer system...

Sensitivity Analysis of a Ground-Water-Flow Model
A sensitivity analysis was performed on 18 hydrological factors affecting steady-state groundwater flow in the Upper Floridan aquifer near Albany, southwestern Georgia. Computations were...

Groundwater Management in the Main Aquifer of High Aswaan Dam
The High Aswaan Dam reservoir replenishes a groundwater aquifer which extends on both sides of the dam lake with variable thickness. The groundwater of this aquifer is used to irrigate...

Design of a Self-Regulating Flap Gate
The objective of the research reported here is to improve the design of a flap gate whose function is to maintain a constant upstream water level over a wide range of flow rates. The self-regulating...

Determination of Vertical Leakage for Nile Valley
The determination of vertical groundwater leakage is particularly important for irrigated agriculture where adequate drainage is required to prevent high water tables and related problems...

Reliability Analysis in Estimating Turbulent Wind Force on Offshore Structures
This paper presents the results of a reliability analysis carried out to estimate low frequency turbulent wind drag force (including extreme values) acting on a floating offshore structure....

Upgrading Hydraulic Infrastructure for Level One Redundancy
In the current paper a methodology is presented for upgrading any single source water distribution system in order to provide a level one system redundancy at a minimum cost. A level one...
