隆起運動と斜面形の発達 : その理論的考察

概要

論文の詳細を見る
Properties of the slope profiles resulted from continuous uplifting are discussed here based on the mathematical model of slope development, which has been proposed by the writer (HIRANO, 1966a), and is summerized by the relation(∂u)/(∂t)=a(∂^2u)/(∂x^2)-b(∂u)/(∂x)-cu+f(x,t). Provided no particular boundary condition is added, "quasi-convex slope" may be expected to appear in the case when the upheaval takes place continuously. When the uplifting takes place with constant velocity, rate of upheaval has no influence on the properties of the slope except for its steepness. Even in the case when the upheaval takes place continuously, one of the essential factors which decide the properties of the slope is the boundary condition, that is, whether the "removal boundary condition" exists or not, as well as when the upheaval takes place instantaneously. In this connection, the types of slope development denned by PENCK are reconsidered by the writer. Finally, it is also attempted to follow the formation of knick-point by intermittent uplifting, using the model mentioned above.
