An Experimental Study of Geomorphic Thresholds.

Abstract

Both the experimental and field phases of the project indicate that geomorphic thresholds exist and that this concept can be of significance in the recognition of incipiently unstable components of the landscape. For example, within a given region, valley floor slopes, alluvial fan slopes and channel sinuosity usually vary over an order of magnitude. It should be possible to identify at what range of slopes the landforms are unstable and subject to major erosional or depositional change, as a result of a triggering hydrologic event or due to man's intervention. The results of this project should have a significant contribution to make not only in the development of preventive conservation but also to river control engineering. The geomorphic approach requires an understanding of landform history, which can provide a basis for working with the natural system in order to accomplish conservation or river stability goals.
