Abstract:
The amplified human role in shaping natural processes makes it imperative to understand the interactions between abiotic and biotic processes, whcih pertain particularly to the most dyanamic aboitic factor,water. The assessment of environmental parameters is indispensable for the sustainable management of the aqutic system .The conscious harnessing and pampering to protect the characteristics of the ecosystems is the of the day.This thesis attempts to characterize the chemical dynamacity of a tropical estury in relation to the bio, geo and physical processes and thereby to propose a management scheme for its sustainability. Micro speciation is used as a tool for this.

Abstract:
Considerable number of factories and related establishments forming an industrial complex are located in the upper reaches of the estuary from Varapuzha about 10km from cochin barmouth to Alwaye while lower down are the retting grounds at Vaduthala and nearby places at about 5km from the barmouth. Muncipal wastes from the city population of over 5 lakhs effluents and solid waste from several fish processing factories and other land washings around Willington island reach the estuary move near its lower reaches close to the barmouth. Cochin estuary is the biggest in the state providing water front for the largest number of industries from the small retting grounds of Vaduthala to the huge fertilizer factories of Udyogamandal and receiving the highest quantity of town sewage and land drainage. The estuary contributes itself as nursery ground for shrimps and related fishery as well. Study of this estuary therefore contributes to a typical environment as regards to pollution problems in the tropics and hence the scope of the present investigation
