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 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.

In this study, the influence of a discontinuous aquitard on the seepage from a recharge source in a multilayered aquifer system, with the prescribed hydrogeological set-up, has been subjected to investigation.

The report is a compilation of abstracts and annotated bibliography of hydrological literature from select national and international Journals for the year 1996-97. 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.

This report is a compilation of the hydrological news in the print media in the country for the year 1997-98. The report is an attempt to put forth diverse hydrologic information and events reflecting the problems and indicate solutions for hydrologists, planners and water resource managers in particular. Five national newspapers like Hindustan Times, Indian Express and Hindu etc., have been referred to, for tracking the Indian hydrological events due to flood, drought, quality, demand supply and availability.

The study attempts to do flood inundation and flood plain feature mapping as well as undertake river planform measurements for a part of the river reach of Satluj. The river is a part of the Indus system and faces flood during monsoon months in spite of various flood control measures that have been adopted. The vast expanse of land adjoining the river course is inundated by large floods.

The report deals with the hydrological aspects of flood disaster management, a multi-disciplinary field that endeavors to enhance the total productivity of the flood plains wherein losses are only a part of it. There are climatological and part-climatological causes of flooding and basin conditions, channel conditions and network conditions intensify floods.

The report attempts to compile all the published works on the Sagar lake in one place. This includes brief description of the historical and the geographical background of the lake, details of water quality analysis carried out in various years, present position of the lake and various schemes proposed and implemented for the improvement of the condition of the lake.
