Abstract: Tests of the slope‐area gaging technique at 16 sites in gravel and boulder‐bed rivers with slopes of 0.4–4% in upland Britain show that the field measurements must include detailed surveys of bed cross section and transverse ...

Abstract: 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 differences in resistance variation between ...

Abstract: Existing bed-load transport formulas may overestimate the transport rate in mountain rivers by two orders of magnitude or more. Recently published field data sets provide an opportunity to take a fresh look at the bed-load ...

Abstract: A field method for measuring the flow drag force on individual boulders on a riverbed is identified and tested. Drag is determined from the momentum deficit in the boulder wake, obtained by measuring the flow velocity in ...

Abstract: This paper presents the results of load and resistance factor design (LRFD) calibration of the facing limit states for soil nail walls. The current AASHTO facing load model and a modified model together with the AASHTO ...

Abstract: Steel bar mat is a common reinforcing material in mechanically stabilized earth (MSE) walls. The current method to calculate the pullout capacity of these materials is an empirical-based formulation found in AASHTO and ...
