The role of infrequently mobile boulders in modulating landscape evolution and geomorphic hazards

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.

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

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.

The hydraulic geometry of stream channels and some physiographic implications

TL;DR: In this paper, the hydraulic characteristics of stream channels are measured quantitatively and vary with discharge as simple power functions at a given river cross section, and similar variations in relation to discharge exist among the cross sections along the length of a river under the condition that discharge at all points is equal in frequency of occurrence.

Channel-reach morphology in mountain drainage basins

TL;DR: In this article, a classification of channel-reach morphology in mountain drainage basins synthesizes stream morphologies into seven distinct reach types: colluvial, bedrock, and five alluvial channel types (cascade, step pool, plane bed, pool rime and dune ripple).

Hydraulics of High-Gradient Streams

TL;DR: In this article, a simple and objective method was employed to develop an equation for predicting the Manning roughness coefficient of high-gradient streams by using multiple regression techniques and measurements of the slope and hydraulic radius.
