Shoreline changes along the Northern coast of Chennai port, from field measurements

Shoreline movement is a complex phenomenon that is the result of both natural processes and man-made effects. Some of these processes occur over millennia; others are recent and may be cyclic. Understanding changes to the shore requires both a complete understanding of the underlying processes and an ability to accurately measure the changes. This paper presents the one-line shift method of determining datum-based shoreline positions for every month using Arc-GIS and sectional changes using data field measured data with the help of real-time kinematic GPS (RTK-GPS). This result shows the erosion and accretion patches and its volume for the study area. © 2013 © 2013 Indian Society for Hydraulics.
