Water Management

This case study presents a erosion response model for watershed prioritisation in Bajaj sagar sub catchment of Mahi basin. The natural hydrologic processes like erosion of soil, movement of soil and its deposition in various parts of reservoir are very crucial phenomena occurring in any watershed. Erosion of soil is a very complex process which is affected by many factors and the loss caused is irreversible.

The presentation by M N Thippeswamy (Retd. Chief Engineer of BWSSB) deals with the operation and maintanance of water supply systems. The structure of the presentation is as follows -

• Key issues regarding water supply scenario around the World
• Definition of Operation and Maintenance
• Key issues before the water authorities for water supply O & M
• Objectives of Operational System and Management
• O & M of Water Resources for quality and quantity
• O & M of Conveyance system of water resources
• O & M of Water Treatment Plant
• O & M of service reservoirs and distribution pipeline
• O & M of drinking water quality maintaining and surveillance
• O  & M of billing and collection
• O  & M of Energy Audit
• Water Audit and Leakage Control
• System Management
• Public Private Partnership (PPP / PSP)

This study by the National Institute of Hydrology deals with the geomorphologic & land use planning for Danda watershed in Tehri Garhwal district of Uttar Pradesh.

Micro-watershed level planning requires a host of inter-related information to be generated and studied in relation to each other. Remotely sensed data provides valuable and up-to-date spatial information on natural resources and physical terrain parameters.

This study presents a remote sensing based rapid watershed health appraisal of NWDPRA watersheds of Rajasthan. The study area is distributed across 8 agro-climatic zones ranging from desertic western plain to humid southern and south-eastern plain. The satellite data prior to treatment year (1988) was compared with post-treated year (1996), to reveal the noticeable changes over a span of 8 years.

The study is based on a scoping study on ‘Developing Markets for Watershed Protection Services and Improved Livelihoods in India,’ which Winrock International India (WII), New Delhi, undertook as part of a larger international study being carried out by the International Institute for Environment and Development (IIED), London. 

This report titled "Institutional History of Watershed Research in India - The evolution of ICRISAT's work on natural resources in India", by Dr C Shambu Prasad, A J Hall and S P Wani, published by ICRISAT, is a case study of watershed-based development initiatives at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT). It seeks to reveal the way scientists and development practitioners work and how they are shaped by the diversity of partners involved and thereby draw process lessons for ongoing and future work on watersheds in international agricultural research centers (IARCs).

This report in two parts titled "Feasibility of Payments for Watershed Services" is an outcome of a literature review taken up as part of the India PES Project, a collaborative initiative of CISED and NIVA.
