| Zusammenfassung |
| Hydrological data collection requires deployment of physical infrastructure
like rain gauges, water level gauges, as well as use of expensive equipment
like echo sounders. Many countries around the world have recorded a decrease
in deployment of physical infrastructure for hydrological measurements;
developing countries especially have less of this infrastructure and, where
it exists, it is poorly maintained. Satellite remote sensing can bridge this
gap, and has been applied by hydrologists over the years, with the earliest
applications in water body and flood mapping. With the availability of more
optical satellites with relatively low temporal resolutions globally,
satellite data are commonly used for mapping of water bodies, testing of
inundation models, precipitation monitoring, and mapping of flood extent. Use
of satellite data to estimate hydrological parameters continues to increase
due to use of better sensors, improvement in knowledge of and utilization of
satellite data, and expansion of research topics. A review of applications of
satellite remote sensing in surface water modelling, mapping and parameter estimation
is presented, and its limitations for surface water applications are also
discussed. |
