Abstract

The WNW-ESE trending Achankovil Shear Zone (ASZ) in southern India is a major crustal discontinuity of Proterozoic age which separates Kerala Khondalite Belt (KKB) in the south from the Charnockite massif in the north. The Achankovil river drains this structural valley. Although the river bears imprints of various geologic events, including neotectonic activities, it could maintain a straight course even in the lowland indicating its antecedent nature. The present communication is an attempt to study structural controls on drainage development and evolution within ASZ based mostly on geomorphological evidences and also on some geological indicators.

Keywords

Antecedent River, Palaeo Strand Lines, Shear Zone, Structural Valley.

Abstract

Major transition in global water governance includes promotion of integrated water resources management, river basin approaches, decentralization, and involvement of stakeholders against traditional top-down and centrally driven decision-making processes. Although participatory approaches are important to enhance sustainable water governance, engaging general public in the water governance process itself is often a challenge across globe. This note draws perspectives on some of the major challenges faced in India to ensure effective participation in water governance with a focus on factors that motivate the general public to get involved in the process and the necessary changes that may facilitate improving the participatory governance.
