Over het archief
Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.
Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

| Abstract |
Moheskhali is the maiden coastal hilly island of Bangladesh, has increased with a rate of 280.74 m/yr and the area of this Island increased with a rate of 105.6 ha/yr in three decades (27 years). A positive correlation revealed by analyzing the shoreline changes, erosion and accretion of Moheskhali Island in last 27 years. The result showed that shoreline has increased about 272.75 mm with an annual rate of 11.85 mm/yr despite the mean rise of sea-level in this stipulated period. In this study, shoreline change rate was calculated by Digital Shoreline Analysis System (DSAS), and erosion and accretion were calculated by an overlay operation in ArcGIS. A linear regression model was drawn along with sea-level, shoreline, and erosion and accretion data to understand the impact of sea-level. Active storm surge, the abundance of sediment and water discharge, coastal afforestation, etc. played a significant role to increase area of this Island. Based on the positive relationship between rising sea-level and shoreline change, this study finally suggests that satellite imagery, sea-level data and statistical techniques are more reliable to understand the changing nature of shorelines along with sea-level rise. |
