Applications of Remote Sensing and Geographic Information System in Watershed Management

v         ABSTRACT         : removed sensing and GIS argon acting a speedily increasing role in the filed of hydrology and urine system resources think and development. Remote Sensing and GIS with the integration of socio-economic selective information is very useful for drainage basin think and management. geographical Information System (GIS) is an efficient frank technique, spatial info analyst and effective database management tool. These systems are exclusively intentional to store information about the location, network topology and attributes of spatially indite objects such as rivers, wells, wetlands and wastelands, land features, submersed features etc. GIS keep support m each 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 genesis around objects, which are the main re quirements of lavatory planning and management. The water resources management has turn up to be a racy demesne for GIS tool, as it requires analysis of spatial data for its planning and development. Hydrologic models contribute serve as valuable tools in water resources planning and management and their results can be used to quantify impacts of infixed and man-made changes and to evaluate management strategies. The quality and accuracy of these models can he enhanced significantly by drainage basins within the modelling process using GIS. Nowadays researches punctuate on divide - base water resources planning and development for wanton management practices.

This paper gives an overview of applications of remote sensing and GIS in washbasin 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, erect it on our website: BestEssayCheap.com
