Perhaps the most important and overlooked part of the trailer design is its tongue. Have a look at a couple of trailers around your area, and you will see a multitude of materials and designs. The tongue does a couple of important jobs apart from being the part that keeps your trailer attached and at a distance from your tow vehicle. compound channel: (a) hydraulic scour of the floodplain causes (b) a failure of the face of the abutment embankment. In this condition, the floodplain is as erodible (more or less) as is the bed of the main channel. The collapse of the embankment soil (and armor protection) into the scour.

FLOW OF WATER THROUGH SOIL FLOW OF WATER IN A PIPE The flow of water through a rough open pipe may be expressed by means of the Darcy-Weisbach resistance equation ∆h = f L D v2 2g () in which _h is the head loss over a length L of pipe of diameter D. The average velocity of flow is v. f is a measure of pipe resistance.

Flow in Mobile Boundary Channels Introduction Initiation of Motion Bed Forms Channel Resistance Sediment Load the geometry and hydraulic characteristics of the stream channel in all three perspectives (cross-section, plan view, and profile) be fully examined and investigated.
This understanding of the stream is essential to achieve a successful integration of the project with the natural channel. This chapter describes basic design consider. For such channels the vertical section is practically the same as the normal section.
If a flow takes place in this channel with the water surface parallel to the bed, the streamlines will be straight lines and as such in a vertical direction [section 0 –.

The rotational directions of the secondary flows at different cross-sections were different, according to the flow height, the discharge, the bed roughness and the types of floodplain vegeta- by: 8.
Laboratory experiments were conducted to study various aspects of the mechanics of self‐formed, stable, straight alluvial channels in the presence of bed‐load transport. The assumptions used for the formulation of the turbulent diffusion model of Parker () were examined first.

P is the contact length between the water and the channel bottom and sides. Q = Discharge or flow rate [L 3 /T].
R = Hydraulic radius of the flow cross-section [L]. Transverse mixing characteristics of solute in the open channel flow can provide useful information for river environmental management. The lateral mixing coefficient is a crucial parameter for reproducing the transverse mixing either by numerical simulation or by analytical by: 8.
The compound open channel concept characterized the roughness between the main channel and floodplain(s) (Te Chow, ).The main point of advantage the compound open channel concept is related to the defining hydraulic properties the each part of the cross section individually (Al-Khatib et al.
