“…For example, a study in America indicated that the crop yields would be reduced by 2 to 4% if current water erosion rates continue for the next 10 decades (Trimble and Crosson, 2000). New reports claim that there is a clear relation between erosion and changes in carbon cycle and precipitation (Weltzin et al, 2003;Nearing et al, 2005). Measurements at the field scale indicate that the soil organic carbon pool (SOCP) decreases significantly after long-term severe erosion, which in turn may release huge amounts of CO 2 to the atmosphere and eventually contribute to global warming (Lal and Pimentel, 2008).…”

“…Among these factors however, the spatiotemporal variations of rainfall play a key role (Apaydin et al, 2006;Wei et al, 2007Wei et al, , 2009Baigorria et al, 2007). Due to poor vegetative cover and fragile ecosystem, surface hydrological responses are even sensitive to small fluctuations of rainfall in the semiarid regions (Yair and Raz-Yassif, 2004;Wang et al, 2005;Nearing et al, 2005;Leblance et al, 2008). Knowledge about the role of rainfall temporal variations on water erosion is thus significant for erosion control and larger-scale hydrological predictions.…”

“…These assumptions can be criticized, because intensities at fine time step (5 min) strongly affect these factors (Cerdan et al 2002), whereas infiltration capacities used in this study never evolve during the modelling process. This point frequently poses a problem in numerous modelling approaches (Nearing et al 2005). Nonetheless, the assumptions are retained here for simplicity and tractability.…”

“…Furthermore, the local population is unaware of the possible flash flooding risk to which they are exposed. The other models developed earlier, such as STREAM, LISEM, or WATEM (De Vente and Poesen 2005;Nearing et al 2005), permit to manage flash flooding susceptibility for a specific basin but not on many basins, since local to outlet scales, and by playing with different intensities. Therefore, these simulations proposed by RUICELLS can improve our knowledge without taking into account rains frequency.…”

A flash flood hazard assessment in dry valleys (northern France) by cellular automata modelling

et al. 2014

This paper presents an application of a cellular automaton-based run-off model (RUICELLS) to a series of small dry valleys in the Seine-Maritime department, northern France, to better assess their susceptibility to flash flood. These muddy floods shortly follow high rainfall (50-100 mm in less than 6 h) and occur in very small areas (\20 km 2 ). A surge generally rushes down through the main valley just a few minutes after rains have peaked. Previous events (n = 69, in the period 1983-2005) have occasionally threatened human lives and have caused significant damage to property and infrastructure. Nonetheless, given the variation among the valleys and the infrequency of events, these floods have not been numerous enough to permit a statistical analysis. Instead, we numerically simulate the possible future flash floods using RUICELLS, a cellular automaton model driven by a set of three deterministic hydrological rules. Simulations have been conducted for 148 basins, each subject to 16 different rainfall scenarios (2.368 simulations in total) to (1) estimate the peak flow discharges (Q), the specific peak flows (Q s ), and the lag times (T) of the flash floods and (2) 123Nat Hazards (2015) 75:2905-2929 DOI 10.1007/s11069-014-1470 warnings and increased vigilance. Our simulations indicate that the number of basins susceptible to flash flooding greatly increases with the higher rainfall intensity, the distribution of sensitive crops (sugar beet, corn, maize, and flax) and the basin morphology. Several small basins could also induce by convergence a bigger flood in the downstream humid valleys. The location of the highest simulated discharges is aligned with observed events, and this comparison provides an evaluation of the modelling performance and of the credibility of the results.

The WEPP (Water Erosion Prediction Project) is a daily simulation model developed to predict soil erosion on all lands. It is based on hydrology and erosion processes -detachment of soil by raindrops and flowing water, sediment transport by flowing water, and sediment deposition in flowing water and impoundments. It maintains a daily accounting of the condition of the soil and above-and belowground biomass. It computes an estimate of the disposition of all water that falls on the land surface, whether from rain, snow or irrigation. It computes rates and volumes of runoff and estimates hydraulic shear, the detaching force occurring in rills and channels. It also computes the size distribution of detached sediment and the size distribution of sediment discharged from the area of interest.It can be used on individual hillslopes (Hillslope version), and on small watersheds (Watershed
