Shoreline Erosion at Mad Island Marsh Preserve, Matagorda County, Texas
… of Texas (TNC) is concerned with the amount of shoreline erosion taking place at its Mad Island Marsh Preserve (MIMP), located in Matagorda Bay, Texas. The MIMP is a 7,100 acre nature preserve that borders the Gulf Intracoastal Waterway and is eroded by waves generated by barge traffic. TNC is …

A quantitative analysis of shoreline erosion processes, Lake Sakakawea, North Dakota
<p> Shoreline erosion is a problem at Lake Sakakawea and Lake Audubon, North Dakota. Land is lost, water quality is adversely affected, and reservoir storage capacity is decreased. </p><p> Instrumentation of the eastern shores of both lakes began in 1983 to quantify bank erosion by process (e.g., …

Modeling Cle Elum Reservoir Shoreline Erosion: GIS Analysis to Support Cultural and Environmental Resource Management, Yakima Basin, Washington
… this study was to examine areas prone to further shoreline erosion to inform resource management. This research included the use of airphotos and fieldwork to identify erosional shorelines. Erosion was verified in the field using a video survey as well as indicators such as shoreline slope, …

Patterns and Associations of Shoreline Erosion and Developed Land Use Change in the Lower Meghna Estuary of Bangladesh
… economic resources due to the hazards of coastal erosion. Scientific research has indicated that 70% of the planet's sandy coastal environment is being impacted by coastal erosion. Due to the different characteristics of the lands in the coastal zone versus other areas, it is important to …

“We Look to the Water”: Coastal Erosion and the Transformation of shíshálh Cultural Landscapes
Rising sea levels, storm surges, and shoreline erosion are ongoing climate change effects that have produced tremendous impacts on Indigenous cultural heritage across the world. Few available studies have focused on how these impacts will affect heritage sites and cultural landscapes on the coast …

Erosion and sedimentation in Lake Ashtabula, southeastern North Dakota
<p> Erosion along the shore of Lake Ashtabula and nearshore and offshore sedimentation were studied from May 1969 to December 1970. The lake, located in the southeastern part of North Dakota, was formed when the Baldhill Dam stopped the flow of the Sheyenne River in 1950. Maximum depth of the lake …

Evaluating ecological function provided by bank stabilization in Box Canyon Reservoir, WA
<p>"Shoreline erosion is a dynamic natural process of alluvial rivers that humans often accelerate and then attempt to control. Traditionally, reduction of shoreline erosion is accomplished by structural means, such as vertical bulkheads and riprap/rock. However, hard bank stabilizing materials can …

The Biology of Spaeroma Terebrans in Lake Pontchartrain, Louisiana with Emphasis on Burrowing
… when given a choice of substrates. The lake shoreline near the Bonnet Carre Spillway is retreating and the presence of S. terebrans contributes to shoreline erosion by weakening and destroying cypress. This has implications for restoration projects in coastal Louisiana.

Subsurface controls on mainland marsh shoreline response during barrier island transgressive submergence
… is presently undergoing the highest rates of shoreline erosion (> 15 m yr -1) in North America as wetlands are converted to open water in a regime of subsidence-driven rapid relative sea-level rise (~1 cm yr-1). Three conceptual models were developed based on the geomorphic relationships …

Provenance of Sands Within the Lower Chesapeake Bay Based on Ilmenite Composition
… are a mixture of sands derived from the bay's shorelines, from offshore, and from relict deposits. Direct fluvial input is probably minor except from the James River, which may serve as a local source of sands in the Thimble Shoals area. Sands in the western half of the bay are primarily …

DYNAMIC EQUILIBRIUM BEACH PROFILES: FORCES OF OFFSHORE SEDIMENT TRANSPORT IN MARYLAND’S CHESAPEAKE BAY
To examine the impact of shoreline erosion on the near shore environment, it is necessary to estimate the quantity and quality of yearly sediment mass that is likely to be added by erosion. Data were collected in 2008 at ten sites along the Maryland shoreline of the Chesapeake Bay and compared to …

Examining Coastal Marsh Sedimentation In Northeastern North Carolina
… Ceramic tiles, radioisotopes (²¹⁰Pb and ¹³⁷Cs), shoreline mapping, and stable isotope ([delta]¹³C and [delta]¹⁵N) analysis were used to evaluate short-term deposition relative to decadal-scale accumulation and assess whether two marshes in northeastern North Carolina were maintaining their …

Seasonal Use of Missouri River Reservoir Deltas by Fishes
… habitats resulting from sedimentation and shoreline erosion, and 2) the seasonal use of delta habitats by fishes. Results from this study will contribute to the understanding of aging reservoir ecosystems and help guide sediment management. Although water resources engineers have monitored …

Nearshore Sedimentology of Eroding Microtidal Estuaries: Bon Secour Bay, Alabama and Perdido Bay, Florida
<p>Estuarine shorelines along the northern Gulf of Mexico are dynamic geologic settings that provide numerous ecological and economic benefits. By definition, estuaries are semi-enclosed bodies of water that receive sediment from two sources: (1) fluvial systems feeding into the estuary and (2) …

Resident Perception of Shoreline Recession in Nags Head, North Carolina
Shoreline recession has become a major concern in many coastal communities. This concern has developed largely because of the tremendous expense associated with trying to save coastal structures from the damage, and even total destruction, that can result from shoreline erosion. While land use …

Improving the spatio-temporal characterisation of South Africa's dynamic coastal zone using hyper-temporal satellite imagery
… detected, linked to urban expansion, mining, shoreline erosion and accretion, dune mobility, as well as climate change–related greening of dunes and receding coastlines. Finally, using higher resolution, hyper-temporal Sentinel-2 imagery, fractional land cover class membership was used to …

Evaluation of Long Term Effects of Erosion Due to Groin Placement in the Northern Yucatan Peninsula
… project covering the Chelem beach area. These erosion control groins were constructed as part of an experimental project to see how the adopted U.S. Army Corps of Engineers guidelines, for installing groins, affected the re-nourishment of the beach.</p> <p>The scope of this study is to document …

Shoreline recession: past, present, and future, Lake Sakakawea, North Dakota
<p>Shoreline erosion is a major problem at Lake Sakakawea, North Dakota. Instrumentation along the eastern shore was initiated in 1983 to measure shoreline recession and determine the processes responsible, with the ultimate goal being the development of a relatively simple equation to predict the …
