Demarcation of Groundwater Prospective Zones in Humid Tropical River Basin: A Geospatial Approach
Groundwater, being a vital resource, needs to be developed with proper understanding about its occurrence in time and space. Unscientific sand mining is a dominant environmental issue in this humid tropical river basin namely Bharathapuzha river basin geographically on central part of Kerala state, southwest part of India. The sandy layers along the river course declines its water holding capac...
متن کاملInformation Interoperability for River Basin
Many countries are adopting water policies and legislative instruments for water management in conformance to the agenda 21. According to this agenda, the use and protection of surface water and groundwater are coordinated at a river basin level. The success of river basin management systems relies upon coordinated actions, including provision of and access to information as well as the capabil...
متن کاملEnvironmental Data Management with the River Basin Information System (RBIS)
The pressure on environmental systems is increasing worldwide due to population growth and the consequences of climate change. Adaptable tools and methods are needed to elaborate information, develop understanding and strategies for sustainable use and management of environmental systems. Such tools should assist scientists, natural resource managers and decision makers in their work by providi...
متن کاملDrought Regionalization of Brazos River Basin Using an Entropy Approach
Assessment and understanding of past climate is an important step for drought mitigation and water resources planning. In this study, streamflow simulation obtained from the variable infiltration capacity (VIC) model was used for drought characterization, and subsequently regionalization was done based on the annual severity level, for the Brazos basin in Texas over a time span of 1949-2000. It...
متن کاملLand Use and Land Cover Changes in a Tropical River Basin: A Case from Bharathapuzha River Basin, Southern India
A study of the spatial and temporal changes in land use and land cover (LULC) was conducted using Remote Sensing and GIS. We analyzed the LULC of Bharathapuzha river basin, south India using multispectral LANDSAT imageries of 1973-2005 time periods. 31% depletion in the natural vegetation cover and 8.7% depletion in wetland agriculture area were seen in the basin during the period. On the other...
