Book Description
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.

Book Description
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

Book Description
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).

Book Description
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. Cover illustration A diversion weir in Tanzania constructed by the farmers with technical assistance from the government.

Book Description
Hydraulic engineering of dams and their appurtenant structures counts among the essential tasks to successfully design safe water-retaining reservoirs for hydroelectric power generation, flood retention, and irrigation and water supply demands. In view of climate change, especially dams and reservoirs, among other water infrastructure, will and have to play an even more important role than in the past as part of necessary mitigation and adaptation measures to satisfy vital needs in water supply, renewable energy and food worldwide as expressed in the Sustainable Development Goals of the United Nations. This book deals with the major hydraulic aspects of dam engineering considering recent developments in research and construction, namely overflow, conveyance and dissipations structures of spillways, river diversion facilities during construction, bottom and low-level outlets as well as intake structures. Furthermore, the book covers reservoir sedimentation, impulse waves and dambreak waves, which are relevant topics in view of sustainable and safe operation of reservoirs. The book is richly illustrated with photographs, highlighting the various appurtenant structures of dams addressed in the book chapters, as well as figures and diagrams showing important relations among the governing parameters of a certain phenomenon. An extensive literature review along with an updated bibliography complete this book.

Book Description
Labyrinth spillways are almost as old as dam engineering. In spite of the fact that they appear as a very good technical-economical compromise, only 0.1% of large dams are equipped with such weirs. The main reason for this is that traditional labyrinth weirs usually cannot be installed on top of concrete gravity dams as they require a large foundat
