The report gives an account of a feasibility study of rainwater harvesting in semi-arid regions. A review of water harvesting systems is followed by a section wherein numerical solutions for surface flow equations are explained. 

In this study, a two-dimensional overland flow model has been developed considering random roughness coefficients and irregular land surface for the analysis of surface flow component. The one-dimensional Richards equation for subsurface flow component has been used for calculating the infiltration from the pervious area.

The report presents the status of risk based hydrologic designs that have been reported in literature and based on these, identifies a computational procedure for developing hydrologic design bases for dams and spillways. Some illustrative examples are presented in order to demonstrate the impact of risk based analysis on current design practices.

This report describes the study of regional flood frequency analysis using peak flood series data of gauging stations of Krishna basin based on at site and regional data combined using the following methods: (a) Index-Flood method (b) PWM based EVI distribution (c) PWM based GEV distribution and (d) PWM based Wakeby distribution.

The report deals with the hydrological aspects of watershed development and describes watershed components and watershed models. It gives an account of the various watershed models in details including data requirement, input, output, various physical processes and governing equation. The suitability of a particular model to Indian condition is also highlighted in the report.

The Rajasthan State Water Policy 2010, describes the critical status of water in Rajasthan in terms of:

• The growing imbalance between demand and supply of water
• Uncertainty in availability of water
• Inequity in access to water
• Low operational efficiency of water resource development projects
• Depleting groundwater resources and deteriorating quality of water
• High cost of service, low cost recovery and low level of expenditure
• Lack of ownership among stakeholders

The policy has evolved out of the earlier policy documents and intends to function from the new perspective of Integrated Water Resources Management, which is holistic and includes a bottom up approach.

The UN-Water website's World Water Day 2010 section, provides access to a range of informative, educational and advocacy material on water.

The documents and publications section includes a range of documents related to water quality, drinking water quality and public health, and water safety planning and management including the safe use of wastewater for agriculture and aquaculture.

The fluorosis section of this website dedicated to Nalgonda district, highlights the acute problem of very high levels of fluoride in the ground water resources of the district and its impact on the health of people - a high prevalence of severe and crippling bone and skeletal deformities. The site has information on the status of the affected people, flouride levels and various articles, petitions and pictures.

The report is a compilation of abstracts of hydrological literature from select national and international Journals for the period 1991-95. Though a sizeable number of Journals are published in the field of hydrology and water resources, scientists involved in different studies and projects find it difficult to go through all of them.

The report presents the hydrologic information and news available from print media and various government agencies mostly for the year 1996-97 compiled state-wise and problem-wise for the whole country.
