Unfortunately Idon't know of any becaue I have found that water supply projects, especially those revolving around dams and irrigation, are mostly planned from a cost-benefit analysis. Cost benefit calculations usually have a tendency to ignore the integration between different resources and base compensation on the largest population of umsns that will benefit as opposed to the smallest and the environment.
Integrated Water Resource management and Sustainable Development varies depend upon your 1. Hydrology, 2.Topography, 3.Area of the Catchment, 4.Demographic profile and 5. Socio-economical conditions.
Apart from that there are minor technical issues to be handled that comes in the later stages.
The first thing you need to know is the usage of water either agriculture or drinking purpose. Second, you need the amount of water available per annum. If you have these answers then you may go for developing a project to consider for sustainable use of the resource. Depending upon quantity of water available, you may go for studies as mentioned by Dr Osama. You may go for adoption of best management practices in fruit farming (like micro catchments, terracing etc. depending upon topography and environmental conditions.
Water management in Murry-Darling Basin in Australia is one of the projects known for IWRM application. You may want to look it up. Water credit mechanism, environmental flow and stakeholders' engagement were some of the main criteria.
Inventory of actors and their roles (institutions, legal framework included) in water resources management in the watershed, developing collabaration between them to mitigating sectorial water management and actions on environmental impact assessment of different projects should be put forward. Further more a good program for monitoring and assessment of activities related to water man within the watershed.
In my opinion, once identified properly the beneficiaries, ask the population what are they are prepared to do and how much are they ready to pay to achieve a sustainable system in which water reuse is affordable to farmers. Ask the farmers what are their priorities and limitations and why do they need more water and what product are they planned to cultivate before planning an irrigation system. Ask the politicians what are they really want to do to support the new project. And finally, ask the technicians if the solution is reasonable.
