Briefly describe the application of remote sensing for water resources pertaining to physical aspects and for agriculture pertaining to human aspects with suitable examples.
Remote sensing is a powerful tool used for monitoring and managing natural resources, offering crucial insights into both physical and human aspects of various fields. In the context of water resources and agriculture, remote sensing provides essential data that aids in understanding, managing, and optimizing these resources.
### Application of Remote Sensing for Water Resources (Physical Aspects)
In the field of water resources, remote sensing plays a critical role in monitoring the physical characteristics of water bodies, such as rivers, lakes, reservoirs, and groundwater. Satellite and airborne sensors collect data on the surface temperature, moisture levels, and water quality, offering valuable information for effective water resource management.
1. Mapping and Monitoring of Water Bodies: Remote sensing helps in identifying and mapping water bodies over large areas. For example, satellite images are used to monitor the extent of lakes and reservoirs, which can change over time due to seasonal variations, droughts, or human activities like dam construction. Landsat satellite imagery, with its long time series, is particularly useful for tracking changes in water bodies across different seasons and years.
2. Water Quality Assessment: Remote sensing allows for monitoring water quality indicators like turbidity, chlorophyll concentration, and surface _______ _____ ____ ___ ________ _________ _______ _________ __________.
