Coastline change reflects the dynamics of natural processes and human activity, and influences the ecology and environment of the coastal strip. This study researched the change in coastline and sea area of the Bohai Sea, China, over a 30-year period using Landsat TM and OLI remote sensing data. The total change in coastline length, sea area, and the centroid of the sea surface were quantified....

Information on the pattern, rhythm and long-term trend of shoreline dynamics is vital to managing the coast, especially in mapping risk areas and in establishing the width of construction setback lines. Unfortunately, such data are often missing or where present of doubtful quality. In this paper, we share our experience in mapping coastline change in Singapore, using geographic information sys...

Continued sea-level rise and coastal development have led to considerable concerns on coastline changes along inhabited islands. Analysis of long-term coastline changes of islands is however limited due to unavailable data and the cost of field work. In this study, high-resolution images taken from 1970–2011 at an interval of about 10 years and topographic maps were collected to determine coast...

Rising sea levels are of significant concern as global temperatures continue to mount. Predicted increases in sea level place coastal regions and cities in danger. This danger is far from uniform; many factors contribute to the relative infiltration of water and its consequent effect on land. Naive considerations of elevation alone would result in a poor model of what happens in real life. This...

A numerical model to represent the mechanisms of cross-shore sediment transport induced by wave and storm events has been established. The model consists of three sub-models (wave transformation, morphodynamic movement, and sedimentation) capable of representing the transport and redistribution of four grain sizes over a coastal area. It is designed to simulate the morphological evolution cause...

A complete, high-resolution coastline of Antarctica, extracted from an orthorectified mosaic of Radarsat-1 synthetic aperture radar (SAR) images through a sequence of automated image processing algorithms, is presented. A locally adaptive thresholding method is used to segment the orthorectified SAR images, while image-object formation and labeling, and edgetracing techniques are used to proces...

considering the increasing rice consumption in the world and also the excessive application of pesticides to increase production, an experiment was conducted to determine the pesticide residues and their effects on nitrogen, potassium and phosphorus content of hashemi, khazar and gohar (sa13) rice cultivars, in a factorial design at randomized complete block design with three replications. in t...
