The role of infrequently mobile boulders in modulating landscape evolution and geomorphic hazards
Charles M. Shobe,Charles M. Shobe,Jens M. Turowski,Ron Nativ,Ron Nativ,Rachel C. Glade,Georgina L. Bennett,Benedetta Dini +7 more
TL;DR: In this paper, the authors review progress on five key questions related to how boulders influence the evolution of unglaciated, eroding landscapes: 1) What factors control boulder production on eroding hillslopes and the subsequent downslope evolution of the boulder size distribution.

Step-Pool Streams: An Adjustment to Maximum Flow Resistance
TL;DR: In this paper, an experiment was conducted to study the maximum flow resistance of step pool streams and the morphology of the steps formed from clastic materials, and the step pool formation was qualitatively simulated to analyze numerically the formation process.
Journal ArticleDOI
Energy Loss in Steep Open Channels with Step-Pools
TL;DR: In this paper, three-dimensional numerical simulations were performed for different flow rates and various geometrical parameters of step-pools in steep open channels to gain insight into the occurrence of energy loss and its dependence on the flow structure.
Equilibrium geomorphological conditions for high gradient bed streams
A N Papanicolaou,A R Maxwell +1 more
TL;DR: In this article, the authors identify the flow conditions under which stable bedforms exist; provide the geometric characteristics of these bedforms; measure the magnitude of the streamwise velocity and energy dissipation factor; and determine the friction factor under various flow conditions and gravel sizes.

Flow Resistance in Very Rough Channels
TL;DR: In this paper , the authors used a double-averaging approach to estimate the width, reach, and doubleaveraged variables for steady, uniform flow in an open channel, using an empirical model for the coefficient of form drag, and a flow resistance model that compares well to a large data set of flow velocity in natural channels.

Characteristics of Step-Pool Morphology in the Mountain Streams of Japan
TL;DR: In this article, the relationship between channel geometry and step-pool morphology is discussed, and the characteristics of the distribution and the geometry of the steppool can be explained by three parameters (particle size, discharge, and channel gradient).
