This technical review paper puts forward robust watershed modeling options as an instrument of participative governance in the water sector, where there is common agreement among stakeholders on assessment of resource and on the manner in which it is to be utilized. Reasonably validated estimates are developed based on existing data and different scenarios are explored. The models offer a scope of assessing the potential changes in watershed hydrology and water availability due to watershed development projects, and can be used as a basis for planning and monitoring.

It very briefly touches on the normative framework within which the model operates as one which is compatible with the principles of sustainable, regenerative use and equitable access participative/ deliberative democracy. It gives a detailed account of the following four models and provides data requirements for them:

• SCS based runoff model for India’s condition
• Haan model
• Datye Sabarmati model
• Critical daily rainfall parameter based modification of Haan model
