This book delves into the modifications made to a one-dimensional model simulating unsteady flow in the Colorado River as it passes through the majestic Grand Canyon. The original model, developed by the author, successfully predicted hydrographs along the river corridor for discharges up to 792 cubic meters per second (m3/s). However, the controlled flood of March-April 1996, which reached a peak discharge of 1,356 m3/s, necessitated extending the model's capabilities to higher flows. The author ingeniously employs data from the controlled flood to extend the model's hydraulic geometry to discharges of up to 1,356 m3/s. This extension is achieved by applying kinematic-wave theory to the flood's receding limb. Furthermore, the numerical method used in the model is modified to handle the rapid changes in discharge associated with the flood more accurately. The significance of these modifications lies in their ability to improve the model's accuracy for discharges greater than 800 m3/s. This enhanced precision is crucial for simulating and understanding high-flow events in the Colorado River, particularly in the context of dam operations and downstream ecosystem management. The book contributes to the ongoing scientific efforts to model and manage water resources in this iconic river system, providing valuable insights for researchers, water resource managers, and anyone fascinated by the interplay of hydrology and geomorphology. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…
