A study is conducted to assess the quality and seasonal variation of surface and ground water sources in and around Chalakudy basin, where intense clay mining activities for tile and brick manufacturing are taking place. The study reveals marked differences in most of the physical and chemical constituents of the ground and surface water sources. The pH, DO, BOD, conductivity, TDS, chloride, hardness and nutrient (N, P and Si) contents of ground water register high values than that of surface water. The conductivity, chloride, sutphate, hardness, calcium, magnesium and iron in the ground water samples fall within the BIS/WHO permissible limits of drinking water standards. Generally, the concentration of chemical components in ground water from clay mine areas is high compared to that from non-cIay ' mine areas. High incidence of bacterial contamination is observed in well waters which stresses the need for proper treatment prior to human consumption.Keywords

Estimation of water balance and sediment yield pertaining to two forest watersheds of southern India was carried out as part of the forest conservation program in Kerala State. The tropical watersheds namely Upper Peppara (-80km2) and Upper Neyyar (-140km2) of southern Kerala region host two important wildlife sanctuaries maintained in the Western Ghats of Indian subcontinent, which have high biodiversity values. The watershed evaluation conducted during the period 1995-2000 reveals that Peppara reservoir catchment yields an average of 1600 tons of suspended sediment and 126Mm3 of run off water every year. On the other hand, Neyyar reservoir at Full Reservoir Level (FRL) carries a suspended sediment load of 1400 tons during the peak monsoon month of June and it receives 207Mm3 of run off from its catchment annually. Unit plot measurements for soil loss indicate that grassland yields substantially high sand-Silt material, of the order of one ton per hectare annually. A management plan map for the Upper Neyyar watershed has been prepared taking into consideration of landscape features. One micro watershed, Panampara (6.73km2) falling within Peppara sanctuary was closely monitored to check its physical health. A number of locally feasible conservation strategies have been proposed to improve the water holding capacity as well as to minimise soil erosion in this subwatershed area. Periodic and manual silt removal from reservoirs during summer periods is recommended to maintain the storage capacity rather than constructing an upper dam or increasing the height of existing dam, as actively being considered.Keywords

The 6th order watershed, which hosts Thiruvananthapuram, the capitol city of Kerala State, India,has been studied in terms of groundwater potential, employing Geospatial Technologies. The watershed receives an average annual rainfall of 2600 mm. Geologically, the major part of the watershed is characterized by Khondalites, Charnockites and Migmatites of Archaean age, and the remaining by Tertiary sedimentaries, Miocene and Holocene formations. All these rocks are extensively lateritised. Geomorphology, geology, drainage, fracture systems in hard rocks and the slope of the terrain play a significant role on the accumulation and movement of groundwater in the watershed. The integration of these data sets has been accomplished through Geospatial technology. The basin area has been categorised into four zones, namely, Very high, High, Moderate and Low in terms of groundwater potential. It is estimated that about 35% of the watershed, comes under the very high to high category in terms of groundwater potential and is confined to the less inhabited upstream reaches. Low groundwater potential category dominates in the watershed which covers 40% of the are a characterized by Built up Area, evidently due to the urbanization.Keywords

Wind power is renewable and helps reduce greenhouse gas emission from the energy sector; however, it also has undesirable impacts on the environment. Studies from Europe and the USA report negative impact of wind farms on wildlife, especially on birds. India, the fourth largest producer of wind energy and also a mega biodiverse country has little information on this issue. Here, we report bird collisions from two wind farms: one at Kutch, Gujarat in western India and another from Davangere, Karnataka in southern India. A total of 47 bird carcasses belonging to at least 11 species in a period of three years were reported from Kutch and seven carcasses of at least three species in a period of one year were recorded at Davengere wind farm. The estimated annual bird mortality rate for Kutch was 0.478 birds/turbine and for Davengere it was 0.466 birds/turbine.Keywords
