Dating and geomorphology of shoreline features in the Qinghai Lake basin of northwestern China suggest that, contrary to previous interpretations, the lake likely did not reach levels 66–140 m above modern within the past ∼90,000 yr. Maximum highstands of ∼20–66 m above modern probably date to Marine Isotope Stage (MIS) 5. MIS 3 highstands are undated and uncertain but may have been at or below...

A mechanistic understanding of river avulsion location and frequency is needed to predict the growth of alluvial fans and deltas. The Huanghe, China, provides a rare opportunity to test emerging theories because its high sediment load produces regular avulsions at two distinct nodes. Where the river debouches from the Loess Plateau, avulsions occur at an abrupt decrease in bed slope and reoccur...

Shoreline change was identified as a vital sign for the Southwest Alaska Monitoring Network because land loss or gain at the marine edge has important ecological and jurisdictional implications to resource managers of coastal National Parks. To evaluate the type of shoreline changes occurring along the 82 km coastline of Lake Clark National Park and Preserve, 7 of 10 cross-shore beach profiles ...

The present paper reports the observations of waves and beach morphology at two sites in Japan. One is the HORS Research Pier and the other is the Niigata coast where multiple shore protection structures have been installed. An X-band nautical radar system was employed for this study. Radar echo images provided instantaneous distributions of wave crests and waterlines along the shore. They were...

[1] Magnitudes of terrestrial (fresh) and marine (saline) sources of submarine groundwater discharge (SGD) are estimated for a transect across Indian River Lagoon, Florida. Two independent techniques (seepage meters and pore water Cl concentrations) show terrestrial SGD decreases linearly to around 22 m offshore, and these techniques, together with a model based on the width of the outflow face...

This paper focuses on automated extraction and monitoring of coastlines by remote sensing techniques using multi-temporal Landsat imagery along Caofeidian, China. Caofeidian, as one of the active economic regions in China, has experienced dramatic change due to enhanced human activities, such as land reclamation. These processes have caused morphological changes of the Caofeidian shoreline. In ...

Shoreline armoring is prevalent around the world with unprecedented human population growth and urbanization along coastal habitats. Armoring structures, such as riprap and bulkheads, that are built to prevent beach erosion and protect coastal infrastructure from storms and flooding can cause deterioration of habitats for migratory fish species, disrupt aquatic-terrestrial connectivity, and red...

assessment of long term erosion and accretion rate of the coastal area is essential for selectionof different types of coastal structures. for example, it is not advisable to develop housing infrastructure onthe coast, which is historically eroding. similarly it is not preferable to select an accreting site for theconstruction of a port in order to avoid annual maintenance dredging after constr...

To better understand the community-wide implications of coastal erosion and erosion management measures to minimize its impacts, we analyzed data on about 1200 properties in nine southeastern U.S. counties. Not only is erosion responsible for hundreds of millions of dollars of property damage each year, the threat of erosion, that is, merely being located in an erosion-prone area, significantly...
