GEOPHYSICAL HYDRAULICS

The harbour in question is a fishery harbour for traditional fishermen in the southern Indian state of Kerala (Kerala is branded as "Gods own country" around the globe for its marvellous beaches, lush green forests, beautiful backwaters and rivers and is chosen as one of the "50 must see" destinations around the globe of a life time).

The accumulated material is transported by littoral action and majority of the material so transported settled inside (without flushing out during low tides) due to some rocky outcrops inside the basin, which create some shadow zones inside the basin area.

Chances are also there for the infiltration of sand through the breakwater trunk- but not yet confirmed in absence of detailed study.

The opening of the basin also have a bearing on the quantum of silt deposited, as the general (the apt word would be "net") trend of littoral drift in this region is found to be from north to south and the opening of the harbour is facing north. This is so because of the possible protection provided by some rocks outside the harbour at some distance into the sea infront of the opening of the harbour.

These material are not removed due to lack of fund with the government. Now funds are received and expected that these material would be removed within a year.

The satellite pic from google can be viewed - lat and long of the place are 11 39' 46" and 75 33' 02" respectively (the present photo is taken from the top of southern breakwater).
