Conjunctive use studies in Pennar delta canal system: Aquifer response modeling – A research report by National Institute of Hydrology
The article is about a study on aquifer response modeling that was undertaken for the southern channel command area of the Pennar delta canal system in Andhra Pradesh. Posted on 30 Jun, 2010 09:00 PM

The study on aquifer response modeling was undertaken for the southern channel command area of the Pennar delta canal system in Andhra Pradesh to understand the potential and dependability of groundwater supplies in the study area so that limited surface waters could be allocated to other uses or areas.

Morphometric analysis of Suddagedda basin - A research report by National Institute of Hydrology
The study, which is a part of the representative basin studies, attempts to do a morphometric analysis of the Suddagedda basin of Andhra Pradesh. Posted on 30 Jun, 2010 08:52 PM

The study, which is a part of the representative basin studies, attempts to do a morphometric analysis of the Suddagedda basin of Andhra Pradesh. The linear, areal and relief aspects pertaining to morphology are studied. In ungauged basins and basins with very little hydrological data, the study of geomorphologic characteristics is important as these can be related with the hydrological characteristics of the basin and thus provide a simple way to understand the hydrologic behavior of various basins.

Estimation of sediment yield and runoff from small watersheds using WEPP model - A research report by National Institute of Hydrology
The study uses WEPP model of the United States Department of Agriculture (USDA) to simulate the flow and erosion processes in Sallopat watershed of Mahi river basin in Banswara, Rajasthan. Posted on 30 Jun, 2010 08:44 PM

The study uses Water Erosion Prediction Project (WEPP) model of the United States Department of Agriculture (USDA) to simulate the flow and erosion processes in Sallopat watershed of Mahi river basin in Banswara, Rajasthan. The WEPP model is a distributed, continuous, small agricultural watershed erosion model. It can simulate the effects of management practices and land use changes on the spatial and temporal variability of the erosion processes within a watershed system. The major features of this model are the ability to –

 

  • Delineate areas of detachment and deposition on a hill slope or along a channel reach
  • Account for the effects of management and land use changes on the erosion process
  • Account for the effects of backwater on detachment, transport and deposition processes within channels

 

Regional low flow analysis of Narmada basin - A research report by National Institute of Hydrology
The study develops a regional hydrological model for estimating flow characteristics at ungauged sites of Narmada basin using climatological, hydrological and morphological variables. Posted on 30 Jun, 2010 08:33 PM

The study develops a regional hydrological model for estimating flow characteristics at ungauged sites of Narmada basin using climatological, hydrological and morphological variables. The term low flow is broadly used to describe stream flows that are significantly below average or below normal flow levels.

Water quality monitoring and evaluation of Mansar lake - A research report by National Institute of Hydrology
The study attempts water quality monitoring of Mansar lake to detect the various water quality parameters. Posted on 30 Jun, 2010 07:56 PM

The study attempts water quality monitoring of Mansar lake to detect the various water quality parameters. The lake water conditions were monitored by collecting water samples from different depths to determine the spatial and temporal variations.

Groundwater quality studies in Belgaum city - A research report by National Institute of Hydrology
The study attempts to understand the status of groundwater quality in Belgaum city, where water scarcity is a major problem. Posted on 30 Jun, 2010 07:49 PM

The study attempts to understand the status of groundwater quality in Belgaum city. In groundwater assessment studies, evaluation of the quality of groundwater is as important as the quantity because the usability of groundwater available is determined by its chemical, physical and bacteriological properties.

Sensitivity analysis of aquifer parameters in Anantapur - A research report by National Institute of Hydrology
The study attempts to develop an in-depth understanding of the behaviour of open wells in the region through sensitivity analysis of the aquifer parameters and its method of pumping test design. Posted on 30 Jun, 2010 07:42 PM

The study attempts to develop an in-depth understanding of the behavior of open wells in the region through sensitivity analysis of the aquifer parameters and its method of pumping test design. The estimation of groundwater balance and flow paths requires appropriate aquifer parameters, representing the study domain.

Seasonal changes in groundwater hydrochemistry of Kakinada town - A research report by National Institute of Hydrology
The report deals with the results of a study on seasonal changes in groundwater hydrochemistry of Kakinada town of Andhra Pradesh. Posted on 30 Jun, 2010 07:31 PM

The report deals with the results of a study on seasonal changes in groundwater hydrochemistry of Kakinada town of Andhra Pradesh. A total of 29 dug wells and 16 filter points were selected for assessing the hydrochemistry. The monthly groundwater levels measured form the wells indicated that they are different for wells located above and below the Mean Sea Level (MSL).

Groundwater quality monitoring and evaluation in and around Greater Guwahati – A research report by National Institute of Hydrology
The study deals with the detection of trace elements – Cu, Co, Cd, Zn, Fe, Mn, Ni and Pb along with pH and ORP in the groundwater of Guwahati and its adjacent areas. Posted on 30 Jun, 2010 07:25 PM

The study deals with the detection of trace elements – Cu, Co, Cd, Zn, Fe, Mn, Ni and Pb along with pH and ORP in the groundwater of Guwahati and its adjacent areas. Toxicity of a metal depends on its concentration, which adversely affects any biological activity. Almost all the metals are toxic at higher concentrations, few in low concentrations and few others even in trace like As, Pb, Hg, Cd etc. The presence of such metals in groundwater is a subject of concern. Groundwater that contains higher amount of metals affects public health to a great extent when it is used for drinking and domestic purposes.

Groundwater monitoring and evaluation in Jammu and Kathua districts - A research report by National Institute of Hydrology
The study looks at chemical characteristics of groundwater in Jammu and Kathua on the basis of thirty water samples collected from open wells during July and December, 1997. Posted on 30 Jun, 2010 07:20 PM

The study looks at chemical characteristics of groundwater in Jammu and Kathua on the basis of thirty water samples collected from open wells during July and December, 1997. The water quality has been evaluated for irrigation and drinking purposes. The suitability of water for drinking purposes has been compared with the standard norms i.e., BIS, 1983 and WHO, 1984.
