Comparing UAV and Pole Photogrammetry for Monitoring Beach Erosion
Sandy beaches are vulnerable to extreme erosion during large storms, as well as gradual erosion processes over months and years. Without monitoring and adaptation strategies, erosion can put people, homes, and other infrastructure at risk. To effectively manage beach resources and respond to …

Resident Perception of Shoreline Recession in Nags Head, North Carolina
… destruction, that can result from shoreline erosion. While land use regulations can be used to help avoid these expenses, their effectiveness is greatly influenced by the attitudes of the areas's local property owners. These attitudes concerning beach erosion may vary significantly between …

Análise das variações morfodinâmicas por funções ortogonais empíricas - Praia do Flamengo (RJ)
Flamengo Beach has been modified because of the land reclamation which resulted in the advancement of the original coastline, and may be exposed to beach erosion. This research is motivated to know the morphodynamics of this beach in order to provide information for making decision in the coastal …

An application of LIDAR to examine erosion in the southern Monterey Bay during the 1997-98 El Nino
… System (GIS) to quantify coastal changes to beaches and dunes in the Southern Monterey Bay region and to qualitatively assess the erosional impact of large storms on coastal dune areas. LIDAR provides a rapid and accurate survey technique to measure topographic elevation. A LIDAR survey was …

The City and its interfaces: An Approach to Recover the Natural and Cultural Landscape at the Beachfront in St. Augustine Beach, Florida
… loss of the uniqueness of a place. A section of beachfront in St. Augustine Beach, Florida that has suffered beach erosion and development pressures was chosen for the study. The result is an alternative proposal to costly dredging and beach reclamation that includes a series of tools, …

Size-selective sediment transport and cross-shore profile evolution in the nearshore zone
… often leads to threatening consequences such as beach erosion and shoreline retreat that concern the coastal community. A new, comprehensive cross-shore morphodynamic model was developed that can be used to describe and predict these phenomena. The study included both physical and numerical …

Comportamento morfológico e sedimentológico do litoral de Itaipuaçú (Maricá) e Piratininga (Niterói), RJ, nas últimas três décadas
… was carried on in the Itaipuaçú and Piratininga beaches (Rio de Janeiro state) with the main objective of understanding the morphological and sedimentological behavior of this coastal region along the last three decades. Data was obtained through the following procedures: (1) new beach …

Eco-geomorphological and hydrodynamic analysis of Mediterranean microtidal beaches in Southern Sardinia
… the stability of coastal systems, accelerating beach erosion, damaging infrastructure and exposing ecosystems and economic activities to significant risks. In this context, integrated coastal management strategies become essential, as they play a key role in predicting, mitigating and adapting …

Reproductive success of sea turtles nesting on Wabasso Beach, East-Central Florida
… (Dermochelys coriacea) were monitored on Wabasso Beach in Indian River County, Florida. Two hundred and forty four of the loggerhead and 2 of the green sea turtle nests were marked during night surveys as the females laid their clutches, permitting exact clutch counts and carapace measurements on …

Multi-scale modeling of the hydrodynamics, sediment transport, and morphodynamics in the nearshore
… dynamics in coastal regions and forecasting the beach response to different wave events has always been demanding in coastal zones. Here, a multi-scale modeling approach was taken to study the hydrodynamics and the underlying sediment transport and morphodynamics for a variety of bed sediment …

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., …

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 …

Comportamiento funcional y ambiental de los diques exentos de baja cota de coronación y su importancia en la ingeniería de costas
… and massive town planning in the active area of beaches, etc. All these reasons lead to the erosion of a large number of beaches and their environmental and landscape degradation. This precarious coastline situation today constitutes a serious problem of great concern. Coastal Engineers, aware of …

Shoreline Erosion at Mad Island Marsh Preserve, Matagorda County, 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 concerned …

Erosion of fractured banks, Lake Sakakawea, western North Dakota
<p> Shoreline erosion at Lake Sakakawea has exceeded originally predicted rates. This thesis is a continuation of a project, begun in 1983, to study erosion rates, causes, and prediction; the purpose has been to describe variations in fracture patterns in shoreline banks and assess their affects on …
