Satellite remote sensing data for hydrological analyses and water resources management

Satellite remote sensing data for hydrological analyses and water resources management are listed below:

1. Groundwater Discharges: Researcher uses satellite data to analyze the groundwater discharges. Locating ground-water discharge areas
2. Land Water Boundaries: Satellite data has been used to convert surface features into land cover maps including water body. Water body detection and delineation with Landsat TM data
3. Management of Water: Satellite images has important use in water management. The USA government agencies are using satellite data for monitoring decreasing water resources, especially in western part of USA by estimating past and present water use and evapotranspiration (ET). The Landsat program and water resources information needs in the United States
4. Monitoring Flooding: Satellite image are in use to map flood damage area. Case studies
5. Monitoring Lakes: Satellite data helps to understand and monitor changes in lake water volume (snow melt) and quality (due to spring run-off). Monitoring lake inventories and health
6. Watersheds Mapping: Satellite data are used to map the watersheds area. Determining land use change within the dog river watershed
7. Wetlands: Landsat data can be downloaded of few decades back, so it can be used to track the number and area of the wetlands. Mapping wetlands and riparian areas
