Description 1306-1310
Hydrodynamic
model has been set up for the area with proposed measures using Delft 3D package and a
sustainable solution for long term benefit is determined. The model domain
considered for the study is 15km along the shoreline and 7 km seawards up to
approximately 25 m water depths. Bathymetry for the model is based on
interpolation of primary data collection by National Institute of Ocean
Technology (NIOT) survey data and General Bathymetric Chart of the Oceans
(GEBCO) data. Submerged reef using geosynthetic tubes is found to be the most
effective shore protection measure. Modelling is carried out for various
combinations of the dyke configuration viz., variation in height of dyke,
providing gaps of different widths and also orientation of dyke. The
configuration consisting of shore parallel submerged dyke of 3.5 m height
consisting of 200 m long dyke segments separated by 60 m gaps at 4 m water
depths run for 1 year, is found to provide the best alternative resulting in
accretion on the land side of the segments thus preventing erosion along the
shoreline. In addition to its effectiveness, it is an environmental friendly
solution enabling the fishermen to carry out their livelihood without any
hindrance. This study describes the modelling studies carried out to check the
effectiveness of submerged reef by varying dyke height and also with provision
of gaps between the reefs.
