1. Introduction Ven Te Chow’s Open-Channel Hydraulics (originally published in English in 1959) remains one of the most authoritative and enduring textbooks in civil and environmental engineering. Its Spanish translation, Hidráulica de Canales Abiertos , is widely used across Latin America and Spain. Accompanying this text is the unofficial but highly sought-after Solucionario (solution manual)—a document that provides step-by-step solutions to the book’s end-of-chapter problems.
