1) Sediment Characteristics along the Ashtamudi Estuarine System
Authors: W. Soumya, Tresa Radhakrishnan and S. Radhakrishnan
Abstract
Sediments sampled at monthly intervals from six different regions in the Ashtamudi estuary for aperiod of one year and analysed for temperature, pH, organic carbon and texture. The temperature ofthe sediment varied between 27oC and 34oC. The sediment pH was noticeably acidic throughout thestudy period. The organic carbon content was high in Kandachira kayal where there is hectic coconuthusk retting activity. The textural characteristics revealed that the sediments are of sandy nature.

2) Distribution Pattern Of Organic Carbon In The Sediments Of Ashtamudi Estuary
Authors: Divya S. Rajan and R. Bindhu
Abstract
An outstanding phenomenon of the coastal belt of Kerala is its extensive system of estuaries and brackish water lakes lying roughly parallel to the Arabian Sea. Ashtamudi is one of the major estuarine systems of the south west - coast of India. The quality of water in Ashtamudi has depleted due to the thoughtless anthropogenic interferences. For the regeneration of Ashtamudi, it is imperative to have knowledge of the sedimentological characters of the estuary such as temperature, pH, texture, organic carbon content etc. So in the present study an investigation was made on the sedimentological properties of the Thekkumbhagam creek of Ashtamudi estuary. Textural data indicated a high percentage of sand fraction (8-93%) and sandy materials dominated all through the year. The organic carbon content reached up to a maximum value of 6.6%.The present study reveals the need for a scientific approach to solve the problem of water quality and to improve the estuarine ecosystem.

3) Analysis Of Effluents Discharged To Ashtamudi Lake From China Clay Industries
Authors: Suma. S., Manoj. S.V., Chithra. P.G.
Abstract
Ashtamudi Wetland is famous for its hydrological functions, its biodiversity, and its support for fish with nearly 100 species sustaining a lively fishing industry. This paper reveals the physico-chemical properties of water samples discharged to the Ashtamudi Lake from china clay industries in Kollam district of Kerala state in India. Water samples collected from the lake were also analyzed. The results indicated that most general physico-chemical properties of the lake water fell within those recommended for domestic water. However the dissolved oxygen present in water is a highly fluctuating parameter which will affect its biodiversity.
