This paper investigates the influence of rainfall intensity and initial soil water content on changes in the near-surface soil hydraulic conductivity. While numerous papers have examined surface sealing, this paper outlines two important innovations: the design and application of time-domain reflectometry probes with the ability to measure and record soil water content at very short time and length...
Micromorphological techniques have frequently been used to describe processes leading to surface crusting. Image analysis can be helpful in quantifying changes in porosity necessary for estimating hydraulic parameters in crust infiltration models. The objective of this study was to quantify changes in pore area and frequency for three pore shapes (round, irregular, and elongate) and four size classes...
Despite numerous studies, the relationship between slope angle and infiltration rate remains unclear. Under different experimental conditions, new processes may be introduced which influence the relationship. The presence of rills, for example, may significantly affect the relationship between slope angle and infiltration rate, so distinct relationships may exist for rill and interrill areas. The...
Extensive afforestation using Pinus and Eucalyptus has taken place in Calabria since the early 1960's to control expansion of calanchi and biancane. In 1978 three small catchments were established near Crotone to monitor the effect of afforestation on hydrological response and sediment yield. In 1992, rainfall simulation experiments were carried out on plots in these catchments to determine more precisely...
A small laboratory flume on a 0.035 m m −1 slope was used to examine particle selection in shallow flows. Initial experiments were carried out on smooth surfaces to measure travel rates of different sediment sizes. Grain size fractions were introduced by hand into 1.37 × 10 −4 to 3.96 × 10 −4 m 2 s −1 flows, and clear selective mobility occurred with slowest...
The relationship between cover density and soil loss under simulated rainstorms of 30 and 60-minute duration and 33 mm h −1 intensity was investigated. Soil loss varied from 0–7.3 g m −2 for cover of 55–95% and reached maximum values of over 80.0 g m −2 (30-minute storms) and 140.0 g m −2 (60-minute storms) for cover of 25% or less. A critical threshold occurred at...
