• Oil spill modeling and weathering analysis on West coast of India

Work is to study the weathering process such as evaporation and dispersion with varying viscosity, salinity, sediment load and temperature

· Analysis of berthing Structures using Plaxis

Different configuration of berthing substructure with respect to the site conditions and suitability. The analysis includes detailed load calculations conforming to the various codal provisions and design of the structure

· Coastal bar dynamics, sensitivity analysis and Sediment transport study along North Goa beaches

Understanding of surf zone dynamics and the response of the sediments

• Wave transmission studies over segmented submerged breakewater

Using MIKE 21 Parabolic Mild Slope (PMS) model and SWASHmodel study of the changes in wave height, when the deep water wave propagates through shallow water and obstructed by a low crested segmented dyke system

• Siltation and tranquility studies for a harbor breakwater

Siltation is strongly related to the physical and environmental conditions and the geometric configuration of the harbour mouth/entrance. Siltation which may occur is being studied for different mouth location configurations and the Accretion/Erosion taking place on the sides of the existing breakwaters is estimated

• Influence of coastal structures at chethy using numerical modeling

The construction of breakwaters at the chethy inlet to facilitate a fishing harbour brought in considerable imbalance in the sediment transport regime of this coast. Accretion and siltation of the chethy harbour are characteristics of the sector south of the chethy inlet while severe erosion is characteristic to northern sector. Annual Seasonal changes show that maximum erosion takes place in SW monsoon season and beach gets recovered in winter. After monitoring shoreline behavior, it is seen that the coastal structures have a major influence in the shoreline change. Moreover, the study indicates that the DHI-LITPACK modules are suitable tools for the estimation of littoral drift and shoreline change studies.

• Numerical modeling study for stabilization of the coastal area with groyne system

This study aims to find the changes in shoreline and sediment transport, when a groyne system is placed by the aid of numerical model LITPACK. The wave data used in the model is obtained from the INCOIS wave rider buoy at a depth of 15m.The study estimated a net transport of 0.5501*105 m3/yr and Gross transport of 0.8336*105 m3/year. Shoreline evolution with groynes is estimated using the LITLINE model

• To prevent the sediment deposit from spilling over to river mouth, it is ideal to bypass the sand to the other side of the river mouth. This study analyses the methodologies for sand bypassing. A numerical model study has been carried out using DHI LITPACK to evaluate the sedimentation. The procedure of sand bypassing using pumps and pipe lines are discussed. The number of Booster pumps to maintain critical velocity, pump capacity, volume of sand bypassed etc. are determined based on the study results

• Gis based coastal vulnerability estimation of lowelevation coastal zones of south asian countries

The identification and mapping of vulnerable coastal area help to produce the proper disaster management plans and thus reduces the risk of coastal population and their belongings to coastal hazards. The boundary maps were collected from Data Meet project and Socio economic Data and Application Center (SEDAC). The elevation data were collected from ETOPO1 and SRTM. Population density data were collected from the NASA Socioeconomic Data and Applications Center (SEDAC). Results show that villages of Bangladesh are the most vulnerable with higher vulnerability index value.

• Studies on Wind and Wave Characteristics at North Kerala Coast using Measurements from Wave Rider Buoy and SAR Data

A concept used to describe mathematically the distribution of wave energy with wave period is called wave spectrum. Using this concept, a highly confusing pattern of interfering waves can be divided into its constituent wave-forms and the results can be used as an aid to wave forecasting. The data used for the study is from the Wave Rider Buoy deployed by INCOIS at Puthiyappa harbor region at a depth of 22m and the wave spectrum analysis is performed in MATLAB.

• Coastal sediment transport studies andshoreline protection management along karausing numerical modeling

Find a better way to reduce the erosion and regain the lost beach in the Kara region through finding the littoral drift and changes by using MIKE LITPACK module.

• Coastal sediment transport studies along kalpakkam using sediment trend analysis and numerical modeling

Complete grain-size distributionsfor these samples were determined using laboratory analysis and GRADISTAT computer program. Grain Size Trend Analysis was then carried out using FORTRAN program and subsequent results were plotted using a software package SURFER to obtain the sediment transport pattern of the region. Results of STA along entire coastal area are analysed an this result matches with the sediment transport in east coast of India. The results obtainedare compared with the numerical model results and this will help in validation of sediment transport evaluated using the numerical model.

• Numerical modeling study for shore line protection and management in vadanappally coastal area

A numerical model study has been carried out using "MIKE 21" to understand the sediment transport rate on Vadanappally site in one year. The Bathymetry of vadanappally site is obtained from field survey data. A suitable option has been suggested based on this study.
