These engineering problems occur in the course of the design and construction of hydroenergy plants, water-supply and other systems. In this book, the author presents his experience in solving these problems from the early 1970's to the present day. During this period new methods of solving hydraulic problems have evolved, due to the development of computers and numerical methods.
