@article{oai:chuo-u.repo.nii.ac.jp:00001245, author = {OUCHI, Shunji}, journal = {中央大学理工学研究所論文集}, month = {Mar}, note = {application/pdf, Two runs of rainfall erosion experiment (one with and another without uplift) are conducted to see the effect of uplift on the development of experimental erosion landform started with a flat-topped square mound. In the first stage of erosion, valley incision and the development of a valley system proceed rapidly regardless of the uplift. The uplift then works to increase the surface relief, while the accelerated erosion keeps the average height at nearly the same level against the uplift. This suggests that the flux steady-state can be achieved while mountains are growing. The ridge tops, where the erosion is not accelerated by the uplift, move up with the uplift, while the accelerated erosion on main valley floors keeps the lowest elevation despite the uplift. As a result, overall relief increased with uplift. The increased sediment supply with uplift encourages the development of alluvial fans, which controls the local base levels, and causes some rise of lower valley floors. The residuals of the increased relief and raised lower valley floors remain longafter the end of uplift. The identical changes of H’ in both runs indicate the lack of significant effect of the uplift on the relief characteristics. The uplift does not change the manner of landform development with time, but it increases the magnitude of surface relief throughout the process., 【査読有】}, pages = {85--97}, title = {EFFECTS OF UPLIFT ON THE DEVELOPMENT OF EXPERIMENTAL EROSION LANDFORM STARTED WITH A FLAT-TOPPED SQUARE SAND MOUND}, volume = {10}, year = {2005} }
