Subsurface storm flow (SSF) can play a key role for the runoffgeneration at hillslopes.Quantifications of SSF suffer from the limited understanding of how SSF is formedand how it varies in time and space. This study concentrates on the temporal variabil-ity of SSF formation. Controlled sprinkling experiments at three experimental slopes were replicated with varying precipitation intensity and varying antecedent precipita-tion. SSF ...
