Resistance to flow determines several important hydraulic parameters in streams and rivers and must be properly represented in models for estimating water discharge and sediment …
This book develops an analysis of the air entrainment processes in free-surface flows. These flows are investigated as homogeneous mixtures with variable density. Several types of air …
Stepped channel design has been in use for more than 3,500 years. Recent advances in technology have triggered a regained interest in stepped design, although much expertise …

Onsite surveys and 75 measurements of discharge were made on 21 high-gradient streams (slopes greater than 0.002) for the purpose of computing the Manning roughness coefficient …

A general hierarchical framework for viewing stepped-bed morphology in high-gradient channels is presented. We emphasize channel units—bed features that are one or more …

A data set of 2890 field measurements was used to test the ability of several conventional flow resistance equations to predict mean flow velocity in gravel bed rivers when used with …

Alternative general forms are considered for equations to predict mean velocity over the full range of relative submergence experienced in gravel‐and boulder‐bed streams. A partial …

Examination of the flow resistance of high-gradient gravel and boulder-bed rivers, using data collected in British mountain rivers with slopes of 0.4–4%, shows that there are …
