Mudflows as a rate process

Mudflows as a rate process
The relaxation theory of mudflows arises naturally out of the rate process theory of soil creep without the need for any further major assumptions. The theory adequately explains the main outlines of the behaviour of mudflows. This includes

Past and present changes of mudflow intensity in the central Caucasus in Proceedings of the Conference on the transformation of mountain environments (TOME), part two.
A lichenometric survey in the Baksan River Basin found that the cessation of mudflow activity in the fourteenth and fifteenth centuries coincided with a prolonged cold period. Mudflow activity has increased in the present century possibly due

The mudflows in Xiaojiang basin

The mudflows in Xiaojiang basin
The number of total times that mudflows burst out in this basin may go up to 1 000 times per year. The mudflows have a high concentration of solid material and their density is almost 2.0 - 2.4 g. cm-2. The average erosion module of the basin

Solifluction and mudflow on a limestone periglacial slope in the Swiss Alps : 14 years of monitoring

This paper summarises the results of long-term observations on a limestone slope subject to deep seasonal frost in the Corviglia area, Upper Engadin. Particular attention is given to highlight 2 types of soil movements (solifluction and mudflow

Erosion and Mudflows at Usu Volcano after the 1977-1978 eruption: August 1977-December 1979
This paper describes the aspects and sequences of erosion and mudflows (rain lahars) at Usu Volcano after the burst of the 1977-1978 eruption, on the basis of field work carried out by the authors from August 1977 to December 1979. An event
of destructive mudflows of October 24, 1978, which triggered by a downpour, is also mentioned. (L'A).

Mudflows' impact on the mountain rivers channel processes is discussed, the processes' features proved to be different within the zones of mudflows formation, transit and deposition| the channel morphology depends on the form of the mudflow deposits
. Aftermudflow flood creates a primary channel in the mudflow deposits, later the channel undergoes a slow transformation by the stream which results in suquential changes of channel types according to changes in the stream slope and discharge. No correlation has
been found between alluvium size and channel slope in mudflows while the correlation is quite close in the channel transformed by water course. Mudflows account also for the lack of correlation between dimensions of the pavement on one hand

During a Chinese-German expedition in Tibet in 1989, numerous morphodynamic processes (mudflows, debris flows and rock fall) and high flood events could be observed due to exceptional rainfalls. Details of the effects are shown in three areas

of the calanco morphology, carried out by a series of photographic surveys, have clearly indicated that a calanco is formed by dynamic landforms such as rills, gullies, crowns and mudflows. The analysis of the evolution of these landforms allowed us to identify

are the main controlling factors, since gullies tend to be concentrated in basement rock areas with lower relief of Maracujá Catchment. The erosion of the resistant soils by human activities (road cuts and trenches), or their mobilization by mudflow movements
