Abstract

While in the field of hydrology remote sensing techniques are often applied and well accepted there is still a deficit in the use of remote sensing techniques in the field of planning, design and operation of water resources systems. It is the aim of this paper to overcome this deficit and encourage water managers to use remote sensing techniques more widely. In order to achieve this, several successful examples of applications of remote sensing to water management are presented, viz. in the fields of design of water supply reservoirs, reservoir sediment monitoring and control, flood forecasting and control, hydropower scheduling, irrigation scheduling and groundwater exploration for water supply purposes. It is shown that remote sensing data cannot be directly used for these purposes since the electromagnetic data observed by remote sensors have to be transformed into hydrological relevant information. Some techniques are presented, how this can be achieved.
