  It is found that during the formation of mud bank along the Kerala Coast, the location of the monsoon surge is always at the equatorial region. The wind speed during the active monsoon situation usually exceeds 15 m/s along the Kerala coast. The wind strength along the Kerala coast during the mud bank formation usually ranges between 5 and7 ms. Considering Alappuzha Mud Bank in the southern Kerala coast as a typical case of biologically productive Mud Banks that form along the southwest coast of India during the Southwest Monsoon (June.

Mud banks become clearly demarcated as areas of calm water adjoining the Kerala coast, during the roughest SW monsoon conditions prevailing in the Arabian Sea. The appearance of mud banks is associated with an increase in the constancy and force of wind towards the east.

Surface currents at that time run parallel to the coast and record -maximum velocity. The “mud banks” of the Kerala coast differ from mud banks reported from other muddy coasts of the world in that they do not form regular relief-forming features.

The transient nature of these “mud banks”, their unpredictable periodicity and the calm and turbid nature of the water column suggest that they are episodes of fluid mud by:   Science often boasts of success stories. Yet there are instances where researches fail to unlock the secrets of nature.

The occurrence of mud banks of Alappuzha, Kochi and Kozhikode in the southwest c. Out of several Mud Banks that occur along the Kerala coast, Alappuzha Mud Bank has especial importance due to (a) its consistent occurrence every year 4,8 and (b) the large fisheries associated Cited by:   The "mud banks" of the Kerala coast differ from mud banks reported from other muddy coasts of the world in that they do not form regular relief-forming features.

It is locally known as Chakara and is generally confined to the inshore waters. This is associated with upwelling and divergence near the bottom between 20 and 30 m. along the coastal line. Upwelling is the process by which bottom nutrient waters come to the surface of the sea. mud bank zones.

Most of the fi sh landings during monsoon take place at the site of the mud bank due to the calmness of the sea in the region. Unveiling the Mystery Mud Banks of Kerala coast differ from mud banks reported from other muddy coasts of the world as they do not form a regular relief-forming feature.

Mud banks have high socio-economic. Mud banks are of region of calm, turbid water with high-suspended sediments that occurs close to the shore during southwest monsoon (June to September) along the Kerala coast ().Mud banks are seen within a water depth of 15 m, often in a semi-circular shape with a radius ranging from 4 to 8 km.

Due to the prevalence of calm waters within the mud bank during. the coast were fixed with the help of land bearings and the others towards the sea by dead reckoning. Each of the eight stations mentioned above was sampled onceha month.

In addition to this, samples were collected from two other mud bank regions, one off Alleppy (Station 9), and­ one off Calicut (Station 10) to study the nature of meiobenthos.

Abstract: Mud Banks are areas of the sea adjoining the coast with calm water during the roughest monsoon conditions of the sea. They provide a rich catch of fishery too.

Regular experimental trawling was done off Porbandar. Mud banks become clearly demarcated as areas of calm water adjoining the Kerala coast, during the roughest SW monsoon conditions prevailing in the Arabian Sea.

The appearance of mud banks is associated with an increase in the constancy and force of wind towards the east. There are 3, boats operating off the coast of Kerala. Of these, around 2, are big boats employing around 14 people per boat. There are also 1, boats that employ around 10 people each.

The formation of mud bank plays a major role in moulding the social and economic set up of the coastal people of that region. Abstract.

formation and characteristics of the mud banks of Kerala. They have defined the mud bank as“ an inshore region where the sea bottom generally has a small elevation of m due to the presence of consolidated mud “.

According to this definition, mud banks are not really formed every year: they only get activated during the SW monsoon. (a) Map of Kerala coast showing locations of mud banks (b) Time Series locations off Alappuzha (mud bank region), south west coast of India.

The mud banks of Kerala have socio-economic relevance as they support livelihoods of fishermen, besides protecting the beaches from erosion.
