Velocity distribution in open channel flow with spatially distributed roughness

Vertical Velocity Distribution in Open-Channel Flow with Rigid Vegetation

In order to experimentally investigate the effects of rigid vegetation on the characteristics of flow, the vegetations were modeled by rigid cylindrical rod. Flow field is measured under the conditions of submerged rigid rod in flume with single layer and double layer vegetations. Experiments were performed for various spacings of the rigid rods. The vegetation models were aligned with the appr...

Determination of Spatially Distributed Velocity for Flow Routing

The physically-based distributed hydrological models play an important role in watershed hydrology. Physical simulation of flow routing depends largely on the field distribution of flow velocity.Terrain analysis studies have previously focused more on the delineation of geomorphologic structures rather than the description of hydraulic factors. As affected by multiple uncertain factors includin...

Experimental Assessment of a 2-D Entropy-Based Model for Velocity Distribution in Open Channel Flow

Velocity distribution in an open channel flow can be very useful to model many hydraulic phenomena. Among the others, several 1D models based on the concept of entropy are available in the literature, which allow estimating the velocity distribution by measuring velocities only in a few points. Nevertheless, since 1D models have often a limited practical use, a 2D entropy based model was recent...
