Bottom racks made by longitudinal bars are hydraulic structures widely adopted for engineering purposes. In the present paper we revisit the problem of their hydraulic design, analyzing the data obtained from a systematic series of experiments carried out in a laboratory flume. For each run we measured the diverted discharge, the water surface longitudinal profile, and using a two-dimensional backscatter laser Doppler anemometer, we measured the velocity field over the rack and in the slit…

Influence of Rack Slope and Approaching Conditions in Bottom Intake Systems

The study analyzes the flow over bottom racks made of longitudinal T-shaped bars. A clear water flow is considered in a laboratory flume. Free surface profiles, wetted rack lengths, and discharge

Experimental and Numerical Modelling of Bottom Intake Racks with Circular Bars

Bottom rack intake systems are one of the most popular structures for diverting water in steep rivers. Intake systems may be used in ephemeral rivers beds to capture part of the runoff flow in the


racks is a hydraulic structure which is placed in the bed of stream through which, part of flow in the main channel is diverted. These structures have very wide application in industry, irrigation,

Experimental study of flow over trench weir with flat bars

Abstract Trench weir is generally constructed across hilly streams to divert water for its use in multipurpose. Presented in this paper is experimental study of flow over trench weir with flat rack

Numerical Study of Sediment Flow Over Bottom Intake Racks With Flow-3D

Bottom intakes are the most useful structure for diverting the flow of steep rivers and providing specific amount of water for hydropower usage. It is crucial to obtain optimum of physical parameters

Hydraulics of circular bottom intake orifices

In this study, the hydraulic characteristics of circular bottom intake orifices were investigated in a hydraulic model. The structure diverts the river‐flow to a hydroelectric power plant through

Flow and Sediment Transport Through Bottom Racks. CFD Application and Verification with Experimental Measurements.

Bottom rack intake systems are designed to get the maximum quantity of water in mountain rivers with important transport of sediments. Some attentions have been given to the occlusion of the racks

Hydraulics of Bottom Rack Intake

Bottom racks are a standard hydraulic structure used as intakes in mountainous regions, to divert water to turbines, and to retain sediment and other solid matter larger than rack spacing. These

Bottom outlet for sewers

The bottom opening is a standard structure in storm sewers, provided the approach flow is supercritical. Based on extended experimentation and by using the governing flow equations, the hydraulic

Modeling overfalls using vertically averaged and moment equations

A new set of vertically averaged and moment equations, which assumes a linear longitudinal velocity distribution and quadratic vertical velocity and pressure distributions, is used for modeling flow

Flow Measurement with Rectangular Free Overfall

Previous experimental works provide different values of the ratio between the end depth and the critical depth. Differences depend on the crosssection shape of the channel, the roughness of the

Hydraulics of Plane Free Overfall

The plane, free overfall is treated by using extended energy and momentum equations taking account of the streamline inclination and curvature. The end‐depth‐ratio is estimated by momentum
