Long term coastal erosion and shoreline positions of Sri Lanka
Coastal zone of Sri Lanka is a key to sustainable development of the country. The erosion of country’s coastal zone has been identified as a long standing problem. Therefore, coastal sediment dynamics around the country has to be identified to develop an appropriate coastal zone management plan. Remote sensing and GIS techniques can be used for quantitative and qualitative analyses of coastal p...
متن کاملCoastal Dynamics 2013 1277 DOES A MORE SOPHISTICATED STORM EROSION MODEL IMPROVE PROBABILISTIC EROSION ESTIMATES?
The dependency between the accuracy/uncertainty of storm erosion exceedance estimates obtained via a probabilistic model and the level of sophistication of the structural function (storm erosion model) embedded in the probabilistic model is assessed via the application of Callaghan et al.'s (2008) Joint Probability Model (JPM) at Narrabeen beach, Australia with three different structural functi...
متن کاملCoastal Erosion Due to Seawater Intrusion into Groundwater Aquifers
Problem Statement: In general, the drinking water systems sourced from ground water (GW) contains chemicals at double the current maximum contaminant levels (MCL) of colloids. However, due to increasing demand of water, groundwater may be subjected to over-exploitation and the natural equilibrium is thus disturbed. A steady-state condition is established between seawater and freshwater in a coa...
متن کاملA rapid overview of coastal erosion in Ghana
This paper provides an overview of the coastline eroding occurrences in Ghana. Ghana is located in West Africa boarded at the south by the Gulf of Guinea and the Atlantic Ocean with four of its ten regions having its major cities lying along the coast. The coastline of Ghana has over the decades experience minor coastal erosion but the recent situation is becoming apocalyptic and needs further ...
متن کاملOperationalization of Sar Polarized Data for Assessment of Coastal Erosion
This study introduces a new approach for operationalization of SAR polarized data on coastal erosion studies. Polarized TOPSAR and ERS-1 data are used for this purpose. ERS-1 data was acquired on the 8 August 1993 and polarized TOPSAR data was acquired on the 6 December 1996. A quasi-linear model and a new model based on the Canny algorithm were used to model shoreline changes. Digitized vector...
