Groundwater table and hydrochemistry of Kakinada coastal aquifer– A research report by National Institute of Hydrology
Posted on 28 Jul, 2010 03:05 PMThe report deals with groundwater table and hydrochemistry of the Kakinada coastal aquifer in East Godavari, Andhra Pradesh.
Groundwater modeling in Ghataprabha sub-basin of Krishna river basin – A research report by National Institute of Hydrology
Posted on 27 Jul, 2010 07:58 PMIn 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.
Estimation of infiltration rates in the Suddagedda basin of East Godavari, AP – A research report by National Institute of Hydrology
Posted on 24 Jul, 2010 06:01 PMThe report on Suddagedda basin, a representative basin of the east flowing rivers of medium sized basins in the east coast of India, presents the outcomes of the infiltration tests carried out using Double Ring Infiltrometer. The basin soil is mainly grouped into three types viz clay loams to clay, sandy loams and forest & loamy skeletal. A total of twenty-eight infiltration tests have been conducted using double ring infiltrometers.
Hydrogeological and geochemical studies of groundwater flow in Suddagedda basin – A research report by National Institute of Hydrology
Posted on 24 Jul, 2010 12:18 AMThe report presents a hydrogeological and geochemical study of groundwater flow for the Suddagedda basin of Andhra Pradesh. Planning of water resources development projects calls for an understanding and analysis of the hydrological characteristics of the region. The hydrogeology and geochemistry of the basin needs to be investigated particularly for a groundwater resources development project.
Evaluation of water supply system of Kakinada town in Andhra Pradesh - A research report by National Institute of Hydrology
Posted on 23 Jul, 2010 09:46 PMThe report presents the evaluation of water supply system of Kakinada town in Andhra Pradesh. The neglect of hydrology of a region, while undertaking planning and development works in an urban environment, has serious consequences, the most notable being non-availability of enough potable drinking water to citizens. Water budget studies can be undertaken with all the available records to improve the functioning of such systems and to identify additional alternate resources.
Evaluation of groundwater table and quality in Krishna delta of Andhra Pradesh – A research report by National Institute of Hydrology
Posted on 22 Jul, 2010 07:45 AMThe 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.
Artificial recharging of an unconfined aquifer with an injection well in Ghataprabha sub-basin– A research report by National Institute of Hydrology
Posted on 21 Jul, 2010 08:47 AMThe 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.
Seasonal mapping of water bodies along the Andhra Pradesh coast using satellite data – A research report by the National Institute of Hydrology
Posted on 18 Jul, 2010 04:43 PMThe report presents the seasonal mapping of water bodies along the Andhra coast using satellite data to analyze the pre-monsoon and post-monsoon variations in the reservoirs. Water resources development be it construction of reservoir, anicut or irrigation canal, calls for mapping of the various water bodies to throw light on its behavior in different seasons in order to plan a judicious water management scheme.
Remote sensing methods are considered to be more appropriate than conventional methods for collection of such information owing to their capability to provide broad synoptic and repetitive coverage of the area in a multi-spectral mode.
Estimation of rainfall recharge in a coastal area through inverse groundwater modeling - A research report by National Institute of Hydrology
Posted on 18 Jul, 2010 02:29 PMThe study focuses attention on the use of inverse modeling technique for estimation of rainfall-recharge in a coastal aquifer. MODINV (Modular Inverse Model), which is software for parameter optimization of 3-D groundwater flow model, MODFLOW is applied to the Central Godavari delta in Andhra Pradesh to estimate the distributed rainfall-recharge during monsoon season.
