斜面侵食に関する実験的研究

Abstract

The significance of slope erosion toward human activities increases with recent economicdevelopment, not only in the conventional soil conservation but also in the maintenance of reservoirand watershed, in the protection of newly developping lands for industry, resident or transfar.In this paper, some wanting informations are discussed through the experiments for systematicunderstanding of erosion mechanism, I. E. with regard to the distribution of flow on the slope andto the evolution of the slope feature which is both the control and the image of flow. The ex-periments are carried out upon a sandy slope under the artificial rainfall, where erosion processis perhaps dominantly determined by the tractive force of flow and the critical one of materials.
