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.

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.

ABSTRACT

Centre for Innovation Incubation and Entrepreneurship at IIM Ahmedabad and Piramal Foundation announce “Piramal Prize 2010” - to enable bold entrepreneurial ideas with potential to reduce the burden of disease across India.  The Prize is an initiative to solve the health crisis by encouraging innovative ideas in th

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.

A national workshop on 'A Decade of the Total Sanitation Campaign (TSC): Lessons Learnt and the Way Forward' was organised in New Delhi on the 22-23rd April 2010, by the Department of Drinking Water Supply (DDWS) and Water and Sanitation Program (WSP). The three presentations below are outputs from the workshop.

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.
