» 3 Projects

“Estimation of Shoreline Changes along Cuddalore Coast- India, using Statistical and Geo-matics Techniques”

Student at BU-Bharathidasan University

Jan-2014 to Jun-2014

The main objective is to Estimate the shoreline changes (erosion and accretion) along Cuddalore coast. The Parameters like Using ENVI software, the image rectification andimage processing like Band Ratio, Grey-Level Thresholding and Edge Enhancement aremade. Exact land-water boundary was obtained by using a nonlinear edge-enhancement technique with Sobel operator (3×3 kernal matrix) on the band rationed image. The digitations of shoreline line of respective year are integrated with extracted shoreline for Quality assessment.

“Storm Surge Prediction & Vulnerability Modeling–Cuddalore to Pondicherry Coast”

Student at BU-Bharathidasan University

Oct-2011 to Jun-2012

The main objectives of the project are to highlight the current activity in surge modeling. Wave height modeling is adopted for increase in the storm surge height from which the inundation distance is calculated. Since it is Empirical approach and to validate the result with engineering derived model are to be used. Comparing this towards the discharge rate over terrain height would give a detailed knowledge about the intensity of
cyclone over the terrain. . Hence the resultant gives a brief admittance to prevent from the future disaster aimed in the coast.
Parameters used for Storm surge Modeling and Coastal Vulnerability Mapping areWinds Speed(Pressure Gradient, Rossby Waves), Geostrophic modeling, Assessment through Sea Surface Modeling (Stadium Effect, Eye-like feature), Wave Height (Proportional, Wind Stress, Inverse Proportional), Assessment through Land Modeling, Manning Equation, Calculation Of Hydraulic Radius, Average Velocity, Discharge Rate and Vulnerable mapping.

“Assessment of Future Sea Level Rise and Its Impact over Coastal Geo-System using Geomatics Technology – Pondicherry Coastal Sector.”

Student at BU-Bharathidasan University

Jan-2011 to Sep-2011

Current Sea Level Rise potentially impacts human populations and the wider natural environment. Along Pondicherry to Chidambaram region of eastern Tamil Nadu is barely affected often by many coastal disasters. An attempt has been made to demarcate the future SLR in this region and its impact over the on shore region, that would get affected, by using Bruun Rule (proposed by “BRUUN” in 1962)- shoreline retreat to an increase in local sealevel. Remote sensing techniques (GIS) have been used for prediction of Future sea level rise and inundation of that region.
