Antidunes on steep slopes
16 When increasing the rates of subcritical flow on gentle slopes, the bed successively produces 17 ripples, dunes and flat beds. Antidunes (defined here as all bed undulations for which the 18 surface gravity waves are in phase with the bed profile) appear only in high flow rates and 19 may be found in some extreme natural flow events. Inversely, on steep slopes flume 20 experiment (S≥1% appro...
متن کاملTopographic Effects on the Seismic Response of Steep Slopes
A frequency-domain parametric study using generalized consistent transmitting boundaries has been performed to evaluate the significance of topographic effects on the seismic response of steep slopes. The results show that the peak amplification of motion at the crest of a slope occurs at a normalized frequency 1t/2 = 0.2, where H is the slope height and 2 is the wavelength of the motion. The i...
متن کاملSteep Slopes: Part I. Simulated Rainfall Conditions
Steep slopes consisting of disturbed soil are very often found in construction, landfill, and surface mining situations. Although legislation and economics dictate that vegetative cover be established on these slopes as rapidly as possible, the occurrence of large rainfall events during critical periods of vegetation establishment can frequently cause extensive soil loss. Sediment generated fro...
متن کاملSlope Length Effects on Soil Loss for Steep Slopes
cients. Normalizing to a unit plot of length 22.13 m, both the USLE and RUSLE use the equation Empirical soil erosion models continue to play an important role in soil conservation planning and environmental evaluations around L 5 (l/22.13) [2] the world. The effect of hillslope length on soil loss, often termed the where L is soil loss normalized to the 22.13-m-long slope length factor, is one...
متن کاملSemi-automatic Landform Mapping at Steep Slopes
The traditional mapping on digital aerial photos and elevation models has its limits at steep slopes where the surface is only very sparsely sampled even in high resolution data sets. As a consequence, there is too few information available to perform a detailed mapping. In this paper we present a framework for augmenting terrain data with additional photos and show how to utilize this addition...
