The book is aimed at engineers involved in the planning, construction, and operation of water management projects. The comprehensive presentation of all relevant areas of hydraulic engineering provides an overview of today's tasks and solutions in the field. The millennia-old discipline of hydraulic engineering has always undergone constant change. In particular, new techniques and construction methods have emerged in the last 50 years that can be applied to solving practical problems. The results of recent research published in this book have already been tested. A separate chapter is dedicated to the modernization and renovation of existing facilities. Important standards and regulations, the European Water Framework Directive, and the hydraulic engineering standard DIN 19700 are considered in their current versions. The specific requirements for the planning of hydraulic structures are also addressed.
