Groundwater if contaminated due to manmade activities cause concern on environment and human health. The aim of the present study is to review the impact of aquaculture on environment briefly and to assess the ground water quality in East Godavari District. Aquaculture activities are major impact on water resources-they are physical, chemical and biological. Physically there is a lot of pressure on water; chemically it is polluted the water as well as land; biologically it introduces exotic species, pathogens and diseases. It is due to poor planning of land and water resources management. These aquaculture ponds require mixing of bore-well or creek waters with fresh water for daily change activities, due to this practice the polluted water is discharged into the channels from the upstream aquaculture ponds that same water is used by downstream aquaculture ponds; this is the m...

High concentrations of hardness block the toxic effects of copper and zinc. For waters where alkalinity is high and calcium is low, photosynthesis may increase the pH to levels that are toxic to fish. Excess alkalinity in an ecosystem can reduce that ecosystem’s ability to sustain life. Ground water contamination with salt water due to aquaculture and thereby changes in alkalinity, hardness and other parameters are discussed.

Km. The Upper Budameru river catchment is digitized with the aid of geospatial data. Drainage, water resources, land use and transport network carried out using IRS P6 LISS-III satellite data. The catchment area comprises of two districts and it is covered in 12 mandals and 120 villages. Nearly 143 habitations are located in them. Most of the habitations are villages developed mostly along the banks of river Budameru. Out of 143 habitations, 89 are situated close to the river Budameru. The drainage pattern of the upper Budameru area is evenly distributed and the predominant drainage pattern is dendritic. The transport network is good. Land use study indicates that the most of the area is under agriculture, and dense forest cover.

The northeastern part of the study area is hilly terrain that mostly covered by forest. This area acts as a good recharge and runoff zone for the low-lying upland area. The central and southern parts of the area occupied by highly porous and permeable sandstone and alluvium forms good repositories of groundwater. Groundwater remains the principal source of irrigation and drinking. Major portion of this area is a flat to gently undulating terrain with clayey and fine loamy soils, facilitating intensive agricultural activities. Thus, the area under study forms an excellent natural geo-environment for human habitat. The present integrated watershed analysis, remote sensing coupled with GIS, is aimed at generating sustainable developmental measures of land and water resources on watershed basis in the area. For that, various thematic layers viz. settlements and transportation, slope and digital elevation model, lithology and structure, drainage and surface water resources, land use land cover, geomorphology and ground water prospects etc. were generated. Overlay of these resource maps further helped in the development of mitigation / treatment strategies in suggesting water harvesting structures. This approach enables the watershed users to take necessary actions to implement such measures for the sustainability of both land and water resources in the entire district. The integrated watershed analysis is aimed at generating sustainable developmental measures of land and water resources on watershed basis in the area. However, the underlying concept of present study is the sustenance of geoenvironment.

Visakhapatnam is one of the fastest growing Coastal cities in India with rapid development of industrial and urban activity. The present study has been carried out to evaluate the Coastal aquifer Pollution and City area Ground water pollution using GIS. Thematic layers have been generated from Ground water quality data and available ancillary data, i.e. for index overlay operations for identification of groundwater pollution zones in the study area using statistical method of point data interpolation and GIS.

Geospatial Technologies can be played an important role for the organization of various natural resources in a watershed. For sustainable development of land and water resources, the Andhra Pradesh State Government is implementing development of watershed programmes on priority basis. The watershed management activities include construction of rainwater harvesting structures, soil conservation measures and environmental protection measures (TAWDEVA). The selected watershed area was Kovvada Kalava Watershed which is a part of West Godavari District of Andhra Pradesh and was identified as drought and flood effected area because of sparse and variable rainfall. Collection of resource data includes digital imageries of study area for two seasons, Survey of India toposheets on 1:50000 scale, and other ancillary data / maps ...

It is one of the prime coastal ecosystems in India and regarded as Ramsar site. It is located in the coastal tracts of Krishna and West Godavari districts of Andhra Pradesh. Overexploitation and mismanagement of land and water resources are exerting detrimental impact on the lake environment. The striking manifestation of this phenomenon is seen various kinds of problems such as shrinkage in Lake area, floods in foreshore area, pollution and siltation of lake, sea water intrusion, land degradation etc. The challenge therefore is, to arrest the degradational processes and restore the lake eco-system. The generation and evaluation spatial information on the terrain conditions that include Tectonic frame work, Lithology, Structure and Geomorphology of the area using geospatial technologies carried out in the present study forms an important component to address various issues in respect of land and water resources. Thus, the sp...
