Rainfall-runoff modelling

Use of Earth Observation for rainfall-runoff modelling

In hydrological and water resources assessments the use of hydro-meteorological time series data from space-borne data sources is often advocated. Satellite data is available for various hydrological processes such as precipitation and evaporation, and from images system characteristics such as elevation, land cover and soils can be obtained. When modelling the relation between rainfall and runoff, many processes of the hydrological cycle as well as properties (i.e. characteristics) of our real world need to be represented in space and time domains. Spatial data serve as input to parameterise a model whereas rainfall and evaporation serve as meteorological forcing terms for modelling. 

Developments in satellite remote sensing in hydrology and runoff modelling aim to develop products for operational use.  Products, however, only can be used effectively when estimates are reliable and accurate. Over the past decade much awareness has risen that hydro-meteorological satellite products require correction since products have (inherent) errors.  

This section contains presentations related to how EO can contribute to accurately model the rainfall-runoff process in a basin. Causes of errors are explained as well as procedures to correct for those errors. A large number of reports are added with example cases on use of satellite products in water resource assessments and runoff modelling.
