In this chapter will focus on surface water – notably the water that is in lakes and reservoirs, rather than rivers and groundwater. This is the water that remains directly on land and represents a significant reservoir for the water cycle. The storage of such water drives many water management applications, as we shall see later, such as reservoir and flood management (chapter 8), irrigation (chapter 9). Here, we will overview the various remote sensing techniques that can be used to detect if a land is covered with water and if so, what is the extent. Later in the chapter we will learn how two successive satellite overpasses can help us estimate storage change a water body may have experience. This storage change can be a crucial component for various water management applications as it helps us understand how much water lakes or reservoirs are storing, losing (to diversion or evaporation) or releasing.
