“…Others have also shown the direct effect of organic mulch in reducing surface runoff (Moreno-Ramón et al, 2014;Cerda et al, 2015;Sadeghi et al, 2015). These organic amendments can have different forms: manure, green waste compost, straw, wood chips, etc.…”

Abstract. The establishment of plant species can limit soil erosion dynamics in degraded lands. In marly areas in the Southern French Alps, both harsh water erosion and drought conditions in summer due to the Mediterranean mountainous climate prevent the natural implementation and regeneration of vegetation. Soil fertility improvement is sometimes necessary. With the purpose of revegetating such areas, we aimed to evaluate the effects of wood chip amendments on the revegetation performance of different native or subspontaneous plant species. We conducted two experiments on steep slopes over three growing seasons (2012)(2013)(2014). The first consisted of planting seedlings (10 species), and the second consisted of seeding (nine species including six used in the first experiment). First we noted that wood chips were able to remain in place even in steep slope conditions. The planting of seedlings showed both an impact of wood chip amendment and differences between species. A positive effect of wood chips was shown with overall improvement of plant survival (increasing by 11 % on average, by up to 50 % for some species). In the seeding experiment, no plants survived after three growing seasons. However, intermediate results for the first and second years showed a positive effect of wood chips on seedling emergence: seeds of four species only sprouted on wood chips, and for the five other species the average emergence rate increased by 50 %.

“…Fernandez and Vega (2014) investigated the effects of straw mulch on erosion control after wildfire and showed that the straw mulch could decrease soil erosion. More recently, the scale effects of two plot sizes of 6 and 0.25 m 2 covered by straw mulch with a rate of 0.5 kg m −2 in changing the time to runoff, runoff coefficient, sediment concentration and soil loss under laboratory conditions were considered by Sadeghi et al (2015). The results of the study showed that the straw mulch had a more significant effect in reducing runoff coefficient, sediment concentration and soil loss at 0.25 m 2 plot scale.…”

Abstract. Various organic and inorganic mulches are used for soil conservation purposes, the effectiveness of which on soil characteristics has not been comprehensively considered from different aspects. The present study surveys the efficiency of straw mulch, manure and TA-200 polyacrylamide with respective rates of 500, 300 and 50 g m −2 in changing sediment concentration and soil loss. The experiments were conducted for sandy-loam soil taken from a summer rangeland, the Alborz Mountains, northern Iran. The experiments were performed under laboratory conditions with simulated rainfall intensities of 30, 50, 70 and 90 mm h −1 and a slope of 30 %. The results showed that the straw mulch decreased soil erosion at rate of 45.60 % compared to the control plots and performed better than manure (8.98 % reduction) and PAM (4.74 % reduction). The results showed that the maximum reduction in sediment concentration and soil loss for all soil amendments occurred at the rainfall intensity of 90 mm h −1 with the rates of 58.69 and 63.24 % for straw mulch, 14.65 and 13.14 % for manure and 20.15 and 23.44 % for TA-200.

Rainfall Simulators (RS) have been used as tools for researches involving the estimation of runoff and infiltration on permeable pavements as well as in evaluating storm build-up and wash-off processes on pavements and roofs. Data obtained with the use of RS allows building a database with parameters which are useful in the implementation of BMPs taking local environment conditions into consideration. The purpose of this study was to develop and calibrate a handy and low-cost RS for hydrological researches. The developed RS can reproduce rainfall with intensities from 40 mm h -1 to 182 mm h -1 . The RS is able to simulate rainfall events with drops of median diameter (D 50 ) of 2.12 mm and kinetic energy of 22.53 J mm -1 m -2 , which represent 90.12% of the kinetic energy produced by a natural rainfall. Spatial distribution of simulated rainfall, which is expressed by the Christiansen's Uniformity Coefficient, was considered satisfactory with a value of up to 87.80%. The developed RS can be used as an alternative for the acquisition of hydrological data in a reduced period of time, under standardized experimental conditions and independently of natural rainfall events. The RS is also capable to simulate rainfall events with varying intensity.
