The process of erosion and desertification affects social communities, agricultural lands and natural resources in coastal areas. The rapid coastline changes would cause social and economic issues in the coastal areas. In this study, Miankaleh coasts and the eastern coastlines of Amirabad port have been surveyed due to existing benchmarks since June 2013 until December 2015 in order to analyze ...

In this paper we present an automatic approach for coastline detection from images which is based on parametric active contours (snakes). Snakes require the definition of an energy functional that reflects the underlying coastline model. As for Antarctica, our application domain, the coastline appearance in the used optical images is heterogeneous. Therefore, a single model does not work equall...

Ningbo City in Zhejiang Province is one of the largest port cities in China and has achieved high economic development during the past decades. The port construction, land reclamation, urban development and silt deposition in the Ningbo coastal zone have resulted in extensive coastline change. In this study, the spatio-temporal change of the Ningbo coastlines during 1976–2015 was detected and a...

Kutum is considered as one of the anadramous species of the Caspian Sea. Due to continuous population decline of the fish since 1975, Iranian fisheries organization started to restock this species. Nowadays, there is growing concern over the effects of restocking on natural populations. For this purpose, population structure and genetic variation of this species in the Iranian coastline of Casp...

Soil salinity is considered as one of the major challenges in coastal agriculture in Bangladesh yet geographical extent of soil salinity and nutrients status have received little or no attention. This study investigated the patterns of soil salinity, total nitrogen, phosphorous, potassium and sulfur between agricultural and fallow land along a 90 km distance from the coastline in Noakhali, Bang...

Often the first step in a remote sensing change detection study investigating coastal dynamics is to delineate the actual coastline from theavailable images. This can often be a difficult task, partly because of the uncertainty over what is and is not the coastline. Whilst it may appear to be common sense to use the water line (where sea meets land) as the best indicator it may not be that easy...

The aim of the paper was to test the possibility of using object based image analyses of Landsat satellite data for worldwide assessment of sea coast changes over time. The coastline in this project was defined as the seaward margin of dunes or land vegetation. The proposed method uses Red and IRed channels of Landsat images for segmentation. The rule based classification of segmented objects i...

We report the result of a 2010 survey of the effects on the Iranian coastline of the tsunami which followed the earthquake of 27 November 1945 (M0 = 2.8 9 10 28 dyn cm; Mw = 8.2), the only large event recorded along the Makran subduction zone since the onset of instrumental seismology. Based on the interview of elderly survivors of the event, we obtained a database of nine values of run-up or s...

The SE coast of Iran is great economic and environmental importance. Global climate change affects this coastline through sea level rise (SLR), compounded by a decrease in sediment budgets coastal areas. This study developed Coastal Vulnerability Index (CVI) for the using satellite, instrumental field data. Eight risk variables were defined: slope, regional elevation, mean tidal range, signific...

In January and February 2002, the presence of certain agricultural pesticides throughout the coastline of the Caribbean island of Martinique was investigated. The tropical climate of the French West Indies is suitable for banana production, which requires intensive use of pesticides. An inventory of all pesticides used on the island (compounds and tonnage) was compiled. Surveys and analyses rev...
