Software for reservoir analysis – A research report by National Institute of Hydrology
Posted on 28 Jun, 2010 05:14 PMThe report describes a software developed by the National Institute of Hydrology (NIH) for reservoir analysis in view of the importance of reservoir operation problem in the Indian context and the non-availability of generalized software for reservoir analysis.
Study of recharge to groundwater due to monsoon rains using Tritium tagging in parts of Narsinghpur – A research report by National Institute of Hydrology
Posted on 28 Jun, 2010 04:48 PMThe study attempts to estimate the recharge to groundwater due to rainfall and irrigation using tritium tagging techniques in parts of Narsinghpur district under the Narmada catchment in Madhya Pradesh. The estimation of recharge to groundwater is crucial to better water resources management, particularly in arid and semi-arid regions.
Spectral response of rice plant canopy – A research report by National Institute of Hydrology
Posted on 28 Jun, 2010 04:26 PMThe study was conducted with the objective of establishing the relationship between spectral reflectance of rice canopy and crop growth. Significant relationship was developed between spectral indices and growth period. The coefficient of correlation between crop growth period and spectral reflectance ranged from 0.41 to 0.97 for the plant growth stages and canopy reflectance in single band and ratio spectra.

Groundwater quality studies in Jammu and Kathua districts (Jammu and Kashmir) – A research report by the National Institute of Hydrology
Posted on 28 Jun, 2010 11:55 AMThe study presents detailed investigations of the chemical quality of groundwater in Jammu and Kathua districts (J & K), carried out to evaluate the suitability of water for various uses. The quality of groundwater of the area has been studied based on the physico-chemical analysis of thirty seven water samples collected from open wells between June and December, 1996.
Various parameters like pH, conductance, alkalinity, hardness, chloride, sulphate, sodium, potassium, calcium and magnesium have been determined for all the samples and compared with the standards to evaluate its suitability for drinking and irrigation purposes.
Irrigation water quality has been computed on the basis of Doneen’s Permeability Index and residual Sodium Carbonate. The higher values of some parameters at certain locations indicate the contamination in groundwater and make the water unsuitable for specific applications.
Field testing of weighing raingauge - A research report by National Institute of Hydrology
Posted on 27 Jun, 2010 10:48 PMThe study attempts to carry out field testing of the weighing raingauge for measurement of rainfall, which is at the core of all hydrological measurements. The tipping bucket rain gauges are generally used for automated recording of rainfall data. It has been reported that the tipping bucket mechanism of such raingauges frequently malfunctions and gives erroneous data, especially during high intensity rainstorms.
Single column hydrologic simulation using SHE models - A research report by National Institute of Hydrology
Posted on 27 Jun, 2010 10:31 PMThe Systems Hydrologique European – European Hydrological System (SHE) is a physically based distributed model and it provides a useful setup for understanding the importance of evaporation data and soil parameters.
In this study, single column hydrologic simulations have been carried out for examining the sensitivity of this model to pan evaporation data of the various stations as well as the increase in conductivity of the unsaturated zone. Furthermore, the reduction in the value of exponent appearing in the Averjanov’s formula and reduction in the values of moisture content at wilting point and residual water content has been studied for a single grid of 2 km X 2 km size of the Narmada river.
Analysis of flow to a multi-aquifer well - A research report by National Institute of Hydrology
Posted on 27 Jun, 2010 08:51 PMIn this study, unsteady flow towards a fully penetrating well screened in both the aquifers of a two-aquifer system separated by an aquitard has been analyzed using numerical approach. Existence of multi-aquifer systems is common in a sedimentary basin.
Assessment of irrigation return flow - A research report by National Institute of Hydrology
Posted on 27 Jun, 2010 08:42 PMThis report presents the various methodologies for correct assessment of irrigation return flow, which is one of the most significant components in the water balance of irrigation command areas. A part of the water applied to the irrigation fields percolates deep to recharge the groundwater and is known as irrigation return flow. In this report methodologies have been presented for assessment of irrigation return flow through soil moisture modeling, water balance approach, experimental determination and groundwater modeling.
