| Zusammenfassung |
| This study investigated the potential for improvement of Soil Conservation Service (SCS)
Curve Number (CN) storm runoff estimates with the implementation of satellite-derived soil
moisture. A large data-set (1980-2007) of daily measurements of precipitation and
streamflow for 135 Australian catchments ranging in size from 53 to 471 km2 was used. The
observed CN, a measure of the soil’s maximum potential retention, was calculated using the
SCS-CN model from measured precipitation and stormflow data. The observed CN
was compared to a soil wetness index (SWI) based on AMSR-E satellite surface
moisture and an antecedent precipitation index (API) based on field observations.
