| Zusammenfassung |
| A simplified, vertically-averaged model of soil moisture interpreted at the daily time scale and forced by a
stochastic process of instantaneous rainfall events is compared with a vertically-averaged model which uses a
non-overlapping rectangular pulse rainfall model and a more physically based description of infiltration. The
models are compared with respect to the importance of short time-scale (intra-storm) variable infiltration in
determining the probabilistic structure of soil-moisture dynamics at the daily time-scale. Differences in
approach to infiltration modelling show only minor effects on the probabilistic structure of soil-moisture
dynamics as simulated in the two models. The partitioning of losses during a single rainfall event are examined
closely and the conditions under which surface-controlled runoff is significant, as a proportion of total
losses, are delineated. |
