Krishna

This paper published in the Indian Journal of Traditional Knowledge makes an attempt to record the fisheries related indigenous technological knowledge in terms of fishing crafts and gears used in river Krishna.

Groundwater conditions in the multi-aquifer system in the delta, were studied through an integrated approach using hydrochemical, hydrogeological and isotopic techniques. This study was taken up because of the reported seawater intrusion into the groundwater system of this agriculturally rich region.

This is a review of KWDT-2 report analysing how it has failed to protect the long term sustainable productivity and ecology of the river basin. It has also failed to understand the water allocations done by previous KWDT-1. KWDT-2 also negated the earlier KWDT-1 allocations at the same time categorically stating that it cannot change water use allocations of previous award.

KWDT-II freshly assessed the yearly yields in the Krishna and determined the award on the basis of the yearly yield at 65 per cent dependability which was assessed at a total of 2,293 tmcft. 

In its order, announced in an open court, the tribunal allocated a total share of 1,001 tmcft to Andhra Pradesh, 911 tmcft to Karnataka and 666 tmcft to Maharashtra with certain restrictions imposed on each State in keeping with the dependable flows of the rivers on which the allocations have been made. The allocation under the first award (KWDT I) was 811 tmcft for Andhra Pradesh, 734 tmcft for Karnataka and 585 tmcft for Maharashtra.

In this study, a two layered finite difference method has been generated for groundwater flow analysis of Ghataprabha sub-basin of Krishna river basin. The conceptual model has been calibrated for steady state conditions and validated for both steady state and transient conditions through USGS, 3D Finite Difference Code and MODFLOW. Various applications were tried out on the calibrated model, like River-Drain influencing the aquifer, reasons for waterlogging and drying out of wells and well design strategies.

The report attempts to analyze the shallow groundwater table and water quality data for about 20 years pertaining to the Krishna delta. The trend analysis of groundwater level data of shallow wells indicates that in the upper part of the delta, the groundwater table moved up during the period 1979 to 1999. This may be due to the dense canal network in the delta and increase in irrigated area over a period of time.

The report deals with the artificial recharging of an unconfined aquifer with injection well in the Hukkeri taluka in Ghataprabha sub-basin of Krishna river. The Ghataprabha sub-basin of Krishna like most river basins of peninsular India has been facing groundwater development problems varying in nature and severity. It has got a wide spectrum of issues such as cases of failure of wells at several places on the one hand, while some areas becoming unfertile due to waterlogging.

The study has been conducted to develop a data simulation model and irrigation schedules for the eastern Godavari delta irrigation system, Andhra Pradesh. It aims at analysis of various factors that influence the irrigation operations and development of appropriate mathematical models and associated computer programs.
