Side weirs are widely used to divert or discharge flows from reservoirs, rivers, artificial channels and sewers. The hydraulic behaviour of this type of weir is complex and difficult to predict accurately using simple methods and the diversity of applictions of side weirs has the potential to complicate guidance. This manual covers the fundamental hydraulic principles and discusses the practical design issues separately for each main strcuture type.

Design of Diversion Weirs Small Scale Irrigation in Hot Climates Rozgar Baban In most developing countries, it is now realised that the most important factor in the success of the agricultural sector is the sustainability of irrigation projects. Diversion weirs are the most important components of these projects. The aim of this book is to teach step by step how to design diversion weirs. It encompasses all technical subjects required: site investigation, hydrological, hydraulic and structural analysis. Many numerical examples show how to relate engineering theories to applications.

A labyrinth weir is a series of duckbill spillways for controlling the flow of water over a dam or channel. This slim volume compares the crest shapes used on weirs, identifies considerations for designing downstream chutes and dealing with sedimentation, explores general guidelines for parameter se

In a previous project, experiments were conducted to determine the hydraulic characteristics of embankment-shaped side weirs in trapezoidal channels with 2.5H:1V side slopes. The present project built on the work done in the previous project. Data from the previous project was reanalyzed, and computations of water surface profiles along side weirs were used to evaluate the effects of channel lope and roughness on weir hydraulics. It was concluded that both the slope and roughness of the main channel should be included explicitly in the calculations of side-weir flows. The physical model was modified to have 4H:1V side slopes, and additional experiments were conducted on side-weir flows. These experiments included both the characteristics of the weir flows and the size and hydraulic effects of the separation zone created in the main channel by the side-weir diversion flow. Based on the experimental results, it is recommended that side-weir discharges be calculated using integration along the weir length and empirical coefficients for the discharge per unit of weir length rather than bulk coefficients for the entire discharge. Empirical formulas are presented for embankment-shaped side weirs. Limited experiments were conducted to evaluate the effects of channel flow on the hydraulics of culverts used for diversion. The empirical results presented in this report were incorporated into a computational scheme for side diversions. That computational scheme is presented in a companion report ("Side-Diversion Analysis System", CRWR Online Report 02-3).

Side-channel weirs can be used for flood control to divert part of a channel's flow into detention basins, thereby reducing peak discharges and stages. After passage of the flood peak, the stored water can be released back to the channel. The Harris County (Texas) Flood Control District is planning the use of several side-channel weirs which will discharge into regional detention basins. The weirs are being designed to divert approximately 50% of peak flows of up to 25,000 cfs, with accompanying depths of up to 25 feet in the channels. A 1:25 scale model was built to investigate the hydraulic characteristics of embankment-shaped side-channel weirs. This thesis describes the model, its use, and the results obtained from the model study. Particular attention has been given to 1) quantification of the discharge which flows over a side-channel weir for given weir geometries and channel flow conditions, 2) the changes which occur in the channel stage along the length of the side-channel weir as water flows past and over the weir, 3) the effects of submergence on the side-channel weir discharge and channel stages, and 4) the effect of tapering the channel (i.e., progressively reducing its width) along the length of the weir. The standard equation for discharge over a normal broad-crested weir was modified slightly for side-weir applications and a bulk discharge coefficient (C[subscript e]) was used. C[subscript e] was correlated with channel flow parameters and weir geometric parameters. The side-weir discharge causes a head change along the weir in addition to the frictional head loss. This additional head change (h[subscript c]) is needed to determine the change in stage between the ends of the weir. The model results were used to calculate h[subscript c] using the energy equation; h[subscript c] was then correlated with channel flow conditions and weir geometric parameters. Submergence effects were characterized by determining the decrease in the bulk discharge coefficient and in the additional head change along the weir for varying values of submergence. Similar analyses were made to determine the side-weir discharge and stage change for weirs placed in tapered channels.

Stepped channels and spillways have been used for more than 2,500 years but recently new construction materials have renewed interest in stepped chutes. The steps significantly increase the rate of energy dissipation taking place on the spillway face and reduce the size of the required downstream energy dissipation basin. Stepped cascades are also used in water treatment plants to enhance the air-water transfer of atmospheric gases and of volatile organic components. This book presents new material on the hydraulic characteristics of stepped chute flows. Two different flow regimes can occur: nappe flow regime for small discharges and flat channel slopes; and skimming flow regime - the hydraulics of each flow regime are described. The book also covers the effects of flow aeration and air bubble entrainment as well as the process of air-water gas transfer taking place above the stepped chute. Practical examples of hydraulic design and a critical review of the risks of accidents and failures with stepped channels makes this book an essential reference tool for professional engineers, postgraduates and researchers in the field.
