Farmers are well aware of the need to boost productivity. In the face of the greater competition for domestic and overseas markets, the farmer who wants to succeed has to tak a business approach to increasing efficiency, reducing costs and improving output. In this environment, water becomes an economic factor and its provision a matter for careful deliberation. This book is designed as a guide for dam owners, engineering students, government agencies, developers, and earthmoving contractors who are responsible for designing, building and using the majority of farm water storages. It is also designed for engineers who have not specialised in small earth dam design for agricultural hydrology who need to design small water storage schemes. 'Small Dams' provides a practial approach and guide to determining catchment yield and the amount of water required in a dam. It also advises on working with engineers and contractors, and outlines the causes of dam failures and how to remedy problems quickly. It further covers relevant legislation, environmental and ecological issues from a global perspective, with explicit reference to various countries around the world. By employing the principles in this volume, in conjuction with the advise of suitably experienced engineers and contractors, small dam builders, such as farmers and land owners, will reduce the risk of failure and ensure long-term success of their dams. An invaluable reference resource for anyone who owns or plans to own a dam, and a useful reference for agencies, contractors and engineers.
