“…Soil erosion is influenced by several interacting factors, including rainfall intensity, soil properties, topography, land cover, spatial scale, and initial and antecedent soil conditions (Hancock et al, 2008;Neave and Rayburg, 2007;Rudolph et al, 1997). Surface sealing and crusting also play an important role.…”

The effect of antecedent conditions and specific rock fragment coverage on precipitation-driven soil erosion dynamics through multiple rainfall events was investigated using a pair of 6-m × 1-m flumes with 2.2% slope. Four sequential experiments -denoted E1, E2, E3 and E4, involved 2-h precipitation (rates of 28, 74, 74 and 28 mm h -1 , respectively) and 22 h without rainfall -were conducted. In each experiment, one flume was bare while the other had 40% rock fragment coverage. The soil was hand-cultivated and smoothed before the first event (E1) only, and left untouched subsequently. Sediment yields at the flume exit reached steady-state conditions over time scales that increased with sediment size. Experiments were designed such that both steady and non-steady effluent sediment yields were reached at the conclusion of E1. Results from subsequent experiments showed that short-time soil erosion was dependent on whether steadystate erosion was achieved during the preceding event, although consistent steady-state effluent sediment yields were reached for each sediment size class. Steady-state erosion rates were, however, dependent on the rainfall intensity and its duration. If steady-state sediment yields were reached for a particular size class, that class's effluent sediment yield peaked rapidly in the next rainfall event. The early peak was followed by a gradual decline to the steady-state condition. On the other hand, for size classes in which steady state was not reached at the end of the rainfall event (i.e., E1), in the following event (E2), the sediment yields for those classes increased gradually to steady state, i.e., the sharp peak was not observed. The effect of rock fragment cover (40%) on the soil surface was also found to be significant in terms of the time to reach steady state, i.e., their presence reduced the time for steady conditions to be attained. Effluent sediment yields for the bare and rock fragment-covered flumes (E1) showed steady conditions were reached for the latter, in contrast to the former. We used the Hairsine-Rose (H-R) model to simulate the experimental data as it explicitly models soil particle size classes. Experiments E1 and E2 involved soil compaction by raindrops, and in this case the model predictions were found to be unsatisfactory. However, compaction was effectively completed by the end of experiment E2, and the model provided reasonable predictions for experiments E3 and E4.

“…The degree of soil compaction depends on many factors including texture, pH, CEC, coarseness of the clay particles, water content, and the presence of organic matter, iron oxides, or free aluminium hydroxide [23]. The most important physical aspects of the soil is the lowering of quantities of available O 2 and the rise in those of CO 2 [24], the decline in the infiltration rates, permeability, irrigation [25], the formation of surfaces crusts and increased runoff and erosion [26], with the consequent loss in nutrients [27]. Also, the absence or reduction in organic matter content can have implications for soil formation, and thus seedling growth as it alters water movement and storage, cation exchange, and nutrient supply [28].…”

Abstract:The Sierra Nevada mountain range near the Mediterranean Sea is an unique environment known for the variety of endemic species.Nevertheless, an alpine ski station situated on the mountain has dramatically affected the landscape, leaving some areas barren. In an effort to restore the vegetation cover, laboratory experiments were conducted with seeds of Genista versicolor Boiss and Reseda complicata Bory, two shrubby plants native to Sierra Nevada. Using different concentrations of two plant growth regulators, Ethrel and N 6 -benzyladenine, seeds from both species were planted in soil sampled from the alpine ski resort. Surprisingly, both Ethrel and N 6 -benzyladenine significantly improved seedling establishment. Consequently, seedling pre-treatment with definite plant growth regulators could be a useful approach to revegetation of the Sierra Nevada mountain range.

Cumulative runoff curves are created by applying constant rainfall of known intensity using a rain simulator. These curves allow us to determine, with good accuracy, the initial loss, the initial time of runoff, and the constant loss. The approach is to model infiltration in an unsaturated medium using a draining reservoir paradigm. Simulated rainfall is applied to a typical soil considered to be composed of two superimposed layers of different permeabilities. This approach enables us to represent the drainage porosity as a function of the constant loss and the initial runoff time, which are measured during the rain simulation. Thus it is possible to calculate the infiltrated volumes, the initial runoff times, and the runoff volumes which are induced by rains of different intensities.Four case studies are used to illustrate the application of our approach.
