Highest Annual Stormflows (mm) In 10 Years

This data set contains Stormflow in South Africa (SA). Stormflow is defined as the water which is generated from a specific rainfall event, either at or near the surface in a catchment. Important statistics on stormflows include annual means, inter-annual variabilities, and magnitudes in wet and dry years and the number of stormflow events per annum exceeding critical thresholds. Distribution patterns over SA show that the highest mean annual stormflows, in excess of 100 mm and > 200 mm, occur in the humid eastern third of SA with its high number of rainfall events.
