Here, calculation approaches, solution methods, and procedures for special problems in technical hydromechanics are provided. For the second edition, all contents have been comprehensively updated. The chapters "Ice in hydraulic engineering" and "Transport of solids" are new. As in the previous edition, practical examples and illustrations illustrate the material. This volume 2 is part of a four-volume series of technical hydromechanical books. Volume 1 deals with fundamentals, volume 3 is designed as an exercise book, and volume 4 deals with hydraulic and numerical models. Contents include the calculation of pressure pipe networks, hydromechanics of fluid jets, theory of wave motion on water surfaces, density currents, transport of solids, and the effect of ice on structures and hydraulic processes.
