| | RIVER and LAKE |
 | | With synergistic inundation extent measured by remote sensing imagers, radar or optical, the monitoring of both surface level and area has relevance to studies of water-related epidemics such as malaria, cholera, and tuberculosis and to the financial losses and human suffering. |
 | | Different classes of waveform shape are observed over rivers and lakes: ocean-like over very major rivers and lakes, high power quasi-specular returns over still water, much lower power over margins or turbulent surfaces, and, most commonly, snagging-affected waveforms as the altimeter routinely off-ranges close to water. |
 | | The main objective of the ESA River and Lake project is to provide the scientific community with easy-to-use, effective and accurate river and lake height measurements from both ERS and Envisat satellite altimeters. |
