Applications of Remote Sensing and Geographic Information System in Watershed Management

v         ABSTRACT         : removed sensing and GIS argon playing a speedily increasing role in the filed of hydrology and body of weewee system resources think and development. Remote Sensing and GIS with the integration of socio-economic information is very useful for drainage basin think and management. geographic Information System (GIS) is an efficient frank technique, spatial selective information analyst and effective database management tool. These systems are exclusively designed to store information about the location, network topology and attributes of spatially referenced objects much(prenominal) as rivers, wells, wetlands and wastelands, land features, submersed features etc. GIS tolerate support m any database queries tied to spatially referenced objects and their associated attributes. They also possess specialized spatial compendium functions such as overlay of thematic layers and buffer district coevals around o bjects, which are the main requirements of lavatory readying and management. The water resources management has prove to be a racy country for GIS tool, as it requires analysis of spatial data for its planning and development. Hydrologic models tolerate serve as valuable tools in water resources planning and management and their results can be used to quantify impacts of internal and man-made changes and to evaluate management strategies. The quality and accuracy of these models can he enhanced significantly by drainage basins at bottom the modelling process using GIS. Nowadays researches punctuate on water parting - base water resources planning and development for well-to-do management practices.

This paper gives an overview of applications of remote sensing and GIS in watershed management. v         INTRODUCTION :         Watershed is a Hydrologic unit. Nowadays watershed based approach of water resources planning, development and management is proved to be important in Hydrological studies. Efficient management of any resource requires a balance sheet that needs to be maintained within a specified boundary. Watershed exhibits a well-defined hydrological boundary unlike area approach ( a village) and has... If you want to build up a full essay, narrate it on our website: BestEssayCheap.com
