Water Resources Management (Impact Factor: 2.46). 01/2009; 23(8):1581-1602. DOI: 10.1007/s11269-008-9342-9

ABSTRACT Integrated watershed management requires a host of inter-related information to be generated and studied in relation to each
other. Remote sensing technique provides valuable and up-to-date spatial information on natural resources and physical terrain
parameters. Geographical Information System (GIS) with its capability of integration and analysis of spatial, aspatial, multi-layered
information obtained in a wide variety of formats both from remote sensing and other conventional sources has proved to be
an effective tool in planning for watershed development. In this study, area and locale specific watershed development plans
were generated for Mayurakshi watershed, India using remote sensing and GIS techniques. Adopting Integrated Mission for Sustainable
Development (IMSD) guidelines, decision rules were framed. Using the overlay and decision tree concepts water resource development
plan was generated. Indian Remote Sensing Satellite (IRS-1C), Linear Imaging Self Scanner (LISS-III) satellite data along
with other field and collateral data on lithology, soil, slope, well inventory, fracture have been utilized for generating
land use/land cover and hydro geomorphology of the study area, which are an essential prerequisites for water resources planning
and development. Spatial data integration and analyses are carried out in GIS environment.

    ABSTRACT: An entropy-based approach is developed for assessing natural groundwater recharge in unconfined aquifers from Southern India. The wells are located in weathered zones which exhibit spatial variability in natural recharge. To determine the fractional amount of rainfall (called natural recharge) marginal entropies and transinformation of rainfall and depth to the water table at selected wells are calculated. Then a ratio of transinformation to marginal entropy of rainfall is used as a measure for assessing natural recharge. Calculated natural recharge yields a good agreement with the results of recharge zones obtained using Remote Sensing (RS) and Geographical Information System (GIS) techniques.

    ABSTRACT: Groundwater in a tannery belt in Southern India is being polluted by the discharge of untreated effluents from 80 operating tanneries. Total dissolved solids and chloride (Cl(-)) measurements in open wells in the tannery cluster vary from 27,686 to 39,100 and 12,000 to 13,652 mg/l, respectively. A mass transport model was constructed using Visual MODFLOW Premium 4.4 software to investigate the chloride migration in an area of 75.56 km(2). Input to the chloride migration model was a groundwater flow model that considered steady and transient conditions. This model was calibrated with field observations; and sensitivity analysis was carried out whereby model parameters, viz., conductivity, dispersivity, and source concentration were altered slightly, and the effect on calibration statistics was evaluated. Results indicated that hydraulic conductivity played a more sensitive role than did dispersivity. The Cl(-) migration was mainly through advection rather than dispersion. It was found that even if the pollutant load reduced to 50% of the present level, the Cl(-) concentration in groundwater, even after 6 years, would not be reduced to the permissible limit of drinking water in the tannery belt.

    ABSTRACT: In semi-arid regions, particularly in hard rock areas (Southern India), shallow aquifers are a major source of potable groundwater. These aquifers are indiscriminately exploited to meet the growing demand of water for domestic, irrigation as well as industrial uses. In order to achieve sustainable development, it is essential not only to delineate the groundwater potential zones but also suitable augmentation schemes which, in turn, require delineation of feasible recharge zones. Such zones are conventionally delineated through the application of various indirect methods, such as geological, hydro-geomorphological, geophysical, 14C-age dating, tracer, entropy method, and groundwater modeling. These methods are, in general, time consuming and may not be economical in the developing countries. A simple, efficient and cost-effective based on cross-correlation method, which takes into consideration the shallow aquifer response to rainfall, is presented to delineate groundwater recharge zones in hard rock areas. The zones so delineated were compared with the results obtained from Remote Sensing (RS) and GIS techniques and were further validated with the aid of estimated recharge values calculated using the modified water-table fluctuation (WTF) method.
