Modeling of a coastal aquifer in Goa using FEFLOW – A research report by National Institute of Hydrology
Posted on 14 Aug, 2010 11:49 AMThe study by National Institute of Hydrology attempts to model seawater intrusion using FEFLOW, an interactive finite element simulation system in the coastal area of Bardez taluka in North Goa and evaluate the impact of increasing groundwater development on the phenomenon. Coastal tracts of Goa are rapidly being transformed into settlement areas and the poor water supply facilities have encouraged people to develop their own sources of water by digging or boring wells.
Second press release from Water Initiatives Orissa on the myth of Surplus Water in Orissa
Posted on 11 Aug, 2010 01:46 PM
- WIO demands the Government of Orissa to come out with a White Paper on water first and then decide on new allocations.
- No new industries should be allowed to draw water unless this White Paper prepared and made public.
- That Orissa is a ‘Surplus Water’ state is a ‘myth’.
Flood situation on 8-10th August in Odisha
Posted on 11 Aug, 2010 11:20 AMThis initiative is an attempt to provide daily updates on Flood Situations and related events/news to water enthusiasts, professionals and citizens concerned about flood in Odisha. News and information collected from Odia news papers, English media (internet editions) and web site of Department of Water Resources, Govt of Odisha are put together at one place to provide an overview of flood in Odisha on a daily basis.
Ingress of saline water in coastal aquifers of Junagadh – A report by CAREWATER
Posted on 08 Aug, 2010 12:02 AMSalinity in coastal groundwater is a widespread problem and may be caused by individual or combined effects of inherent salinity, tidal effect, irrigation by saltwater and by seawater intrusion due to extensive pumping.
Modeling of Cochin estuary using two dimensional finite element model – A research report by National Institute of Hydrology
Posted on 27 Jul, 2010 08:07 PMThe report deals with the modeling of the Cochin estuary along Kerala coast using two- dimensional finite element model. The basic equations for modeling of any surface water problems are the three dimensional hydrodynamic equations arising from consideration of mass and momentum conservation. In vertically well mixed shallow water bodies, the horizontal components of flow quantities are normally much more significant than vertical components.
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.
Modeling of seawater intrusion – A research report by the National Institute of Hydrology
Posted on 13 Jul, 2010 10:48 PMIn this study, a two dimensional numerical model in the vertical plane for simulating miscible transport of saltwater in a coastal aquifer has been developed. In order to simulate the variable density flow, the governing partial differential equation of flow and solute transport has been written in terms of pressure and concentration respectively.
A baseline survey of groundwater quality in coastal aquifers of Andhra Pradesh - A research report by National Institute of Hydrology
Posted on 10 Jul, 2010 01:09 PMThe study provides an analysis of groundwater quality to identify probable pollution or contamination in coastal aquifers of Kakinada in Andhra Pradesh. Sampling surveys have been conducted in the months of May 99, August 99 and November 99 and about 186 water samples were collected from shallow wells, filter points, canal water and rainwater. The spatial and temporal variations of water quality parameters are presented in the report.
