The "Water Engineering Practice" is designed as an introduction to the areas and problems of water engineering, providing students from various disciplines with a comprehensive overview of this fascinating field without being overly theoretical. It covers everything from large water engineering structures (dams, hydropower plants, ship lifts) to smaller issues related to water bodies (bank protection, fish passes, flood obstacles), presenting various structures and construction methods. Reconstructions, modernizations, and maintenance work are given as much attention as new constructions and demolitions. Numerous images and examples vividly and engagingly illustrate the text and formulas. The fourth edition has been updated based on the latest standardization results, and the examples reflect the current state of technology. Key topics include: hydrology, river engineering.
