Climate change adaptation solutions and decision support systems for Cauvery Delta Basin.
Improving the water flow in 6 channels and provide decision support systems to address water scarcity and inadequate water distribution was the challenge.
The scope in Phase I covers 6 channels of Vennar Sub basin of Cauvery Delta and the project is under implementation. The Project phase II was to address the issue of water distribution, assess flood risks, suggest alternative solutions, conduct feasibility studies to improve the overall water management and provide flood risk mitigation interventions in balance 37 channels of Vennar and Cauvery sub basin of Cauvery Delta.
Climate change adaptation and Decision Support Solution
In Project - II, feasible solutions with climate change adaptation, there was a need to create database and hydraulic models for technically supported decisions. The feasibility study included collection and processing of topographic, climatic, hydrologic, hydraulic, groundwater, socio-economic, agricultural, environment related data. The solution required both structural and non-structural interventions. Antea Group developed surface water and groundwater models suggesting feasible design solutions to improve water allocation for irrigation and manage flood risks and supports the implementation of decision support system.
The end result was:
- Hydraulic models and flood risk inundation maps of 37 river channels;
- Feasibility report to establish and modernize structures with climate change adaptation;
- Decision Support System to manage floods and irrigation
