Maharashtra approves cost overrun in irrigation projects, set to complete Gosikhurd project

Tribunal's order over Kalasa-Banduri Project brings respite to Goa and Karnataka

This paper in Journal of Earth Systems Science deals with uncertainties in downscaled relative humidity for a semi-arid region - Malaprabha basin in India. Researchers and decision-makers who assess the impact of climate change in river basin development, agriculture, hydrology, irrigation management, etc., require future scenarios of relative humidity.

In the present study, an attempt has been made to estimate the soil erosion rate in Malaprabha representative basin by using WEPP model and Universal Soil Loss Equation. Soil erosion and sedimentation are the two important natural processes, which need immediate attention from the scientific community. Two major types of erosion are geological erosion and erosion from human or animal activities.

The study uses HEC-RAS to analyse the water surface profiles of Malaprabha river system upto Khanapur for different combinations of discharges through various reaches of the river system. The river system is divided into eleven reaches, and forty one cross sections have been measured and interpolated within these reaches.

Discharge values have been assigned for different reaches according to the ratio of contributing area for each reach. The bridge across the river at Khanapur is reproduced in the modeling system to test its capabilities. Various return period floods have been allowed to pass through the river system to compute the individual water surface profiles.

The hydrological study for the experimental representative basins, Ghataprabha and Malaprabha, of the Krishna river basin attempts to standardize and develop methodologies for providing solutions for understanding and solving various hydrological problems of the hard rock regions of India.

Representative basins are basins, which are selected as representative of a hydrological region within which hydrological similarity is presumed and can be used for intensive investigation of specific problems of the hydrological cycle. This can then take a wide-ranging role representing a broad area to which the data can be transferred. 

This document deals with the proceeding of the final stakeholder workshop titled “Exploring options for sustainable water management in the Malaprabha River Basin”. The one day workshop was jointly organised by the Centre for Interdisciplinary Studies in Environment and Development (CISED) and the Norwegian Institute of Water Research (NIVA) at Belgaum on 5th November 2008.

The India-PES  initiative, was a collaborative effort undertaken on a pilot basis, by CISED and NIVA, for the development of integrated tools and consulting s

 This study by CISED and NIVA aimed at the development of a comprehensive database on the status of water sector and the development of integrated hydro economic model for selected water services in the study area of the Malaprabha basin. The study focused on exploring the feasibility of Payment for Watershed Services (PWS) to improve the water availability through a detailed analysis of the historic hydrologic data and development of a framework of hydrologic and water allocation model. A hydro-allocation model was developed using the software - ArcView SWAT (AVSWAT) and MIKE-BASIN models.

This report by NIVA and CISED has been prepared as part of the India-PES initiative, which was a collaborative effort undertaken on a pilot basis, by CISED and NIVA, for the development of integrated tools and consulting services for Watershed Management and 'Payments for Environmental Services' (PES) in India. Tools and methodologies developed as part of this initiative were tested in the Malaprabha river basin in the state of Karnataka, and the PES implementation was focussed on Participatory Irrigation Management.
