TR-149 : Hydrological year book Malaprabha sub basin 1988-1989

Abstract

The water resources play a key role in the development of a country. These projects need careful planning and after their completion the planning of a water resources projects require adequate reliable hydrological and hydrometeorological data. The rainfall data is being published by India Meteorological Department and other organisations on regular basis and the stream flow data is published by Central Water Commission and State Irrigation Department. But the planning of a project needs much more hydrological information which is not generally available. The hydrological year books are suppose to provide all the necessary possible information required for the purpose in a particular sub-basin.

The Hydrlogical Year Book for Malaprabha sub-basin of Krishna Basin contains description of river basin, present status of water resources development, existing net work of hydrological stations and their salient features. A number of maps have been included in this publication which include Index map, Contour map, Location of Raingauge and Gauge discharge sites, Location-of Ground water observation wells, Soil and land use maps, Normal Isohyetal map and Drought prone area map.The cross-section of the site has also been included. The monthly rainfall and ten daily flow data for the gauging sites have been presented from the start of the observation to 1989. Since this publication relates to the hydrological year 1988-1989, the hourly and daily rainfall data, Vapour pressure, wind, temperature, pan evaporation data for the observation site, daily gauge and discharge data for the. measuring sites and the monthly data of ground water levels of the observation wells, for the year 1988- 1989, have been included. Some relevant information for the Malaprabha reservoir is also provided.

Earlier the Institute has prepared a hydrological Year Book for Hemavathy sub-basin which was appreciated by different organisations and Government of Karnataka in particular. This has encouraged the Institute to bring out a Hydrological Year Book for the Malaprabha sub-basin, one of the catchments taken up for representative basin studies' by the NIH Hard Rock Regional Centre at Belgaum.
