Influence of Rainfall Intensity and Slope on Runoff and Sediment Reduction Benefits of Fine Mesh Net on Construction Spoil Deposits
نویسندگان
چکیده
Fine mesh nets (FMNs) are commonly used as a mulch material to control soil erosion in construction spoil deposits. Here, three rainfall intensities (60–120 mm·h−1) and seven slope gradients (5–35°) were considered relation an FMN’s function of reducing on Soil surfaces covered with FMN (NS) prepared 2 m × 0.5 boxes, smooth surface (SS) the control. Runoff sediment reduction benefits (RRB SRB, respectively) quantify role reduction. The performed better controlling total yield (mean SRB: 35.9%) compared runoff RRB: 5.3%). There was difference between SS NS under low intensity (60 mm·h−1; p < 0.05). different slopes generated similar runoff, significantly yields (p basically decreased increases slope, although RRB fluctuated slopes. results demonstrate that water conservation deposits influenced by slope. effectiveness FMNs needs further investigation context local climates.

Interaction Effect of Slope Aspect and Precipitation Intensity in Runoff and Sediment in Acid Rainfall
Soils are severely damaged by acid rain; acid rain also leads to excessive dissolving of minerals and valuable nutrients in the soil, which weakens vegetation. In this study, in order to determine the interaction effect between the slope aspect and precipitation intensity relative to acid rainfall in the Aghajari and Gachsaran formations, a part of Margha and Kuhe Gach watersheds of Izeh city w...
