MODELING SURFACE ROLLERS AND UNDERTOW VELOCITY PROFILES

Soil Creep and Convex Upward Velocity Profiles

The movement of unconsolidated materials near the Earth’s surface is often driven by disturbances that occur at a range of spatial and temporal scales. The nature of these disturbances ranges from highly variable, such as tree turnover, to periodic and predictable, such as frost heave or creep. To explore the effect of probabilistic disturbances on surface processes, we formulated a granular cr...

Free-Surface Profiles, Velocity and Pressure Distributions on a Broad-Crested Weir: A Physical Study

Basic experiments were conducted on a large-size broad-crested weir with a rounded corner. Detailed free-surface, velocity, and pressure measurements were performed for a range of flow conditions. The results showed the rapid flow distribution at the upstream end of the weir and next to the weir brink at large flow rates. The flow properties above the crest were analyzed taking into account the...
