This investigation is one of a series of model studies used to determine the effectiveness of various dike and bendway weir systems proposed for the improvement of several troublesome reaches on the Mississippi River. This report describes and gives results of test concerned with the development of plans for the improvement of the Dogtooth Bend reach of the middle Mississippi River, located 20 miles above the confluence of the Ohio and Mississippi Rivers. A movable-bed model reproducing approximately 19.4 miles of the Mississippi River (horizontal scale 1:400, vertical scale 1: 100) and using granulated coal as the bed material was employed to develop plans that would improve and stabilize the navigation channel through the reach and eliminate or reduce the need for maintenance dredging. The goals of this study were to improve current flow patterns and widen the navigation channel in Dogtooth and Price's Landing Bends and in the crossings immediately downstream of both bends. Currents concentrating on the outside bank of a number of bends have caused serious problems for barge traffic and major damage to bank stabilization and protection structures. During a high-water event in 1983 the bank line at Dry Bayou (mile 23.3) failed, allowing the river to flow overland for approximately 5 miles.

The second edition of Julien's textbook presents an analysis of rivers from mountain streams to river estuaries. The book is rooted in fundamental principles to promote sound engineering practice. State-of-the-art methods are presented to underline theory and engineering applications. River mechanics blends the dual concepts of water conveyance and sediment transport. Like the first edition, this textbook contains ample details on river equilibrium, river dynamics, bank stabilization, and river engineering. Complementary chapters also cover the physical and mathematical modeling of rivers. As well as being completely updated throughout, three new chapters have been added on watershed dynamics, hillslope stability, and stream restoration. Throughout the text, hundreds of examples, exercises, problems, and case studies assist the reader in learning the essential concepts of river engineering. The textbook is very well illustrated to enhance advanced student learning, while researchers and practitioners will find the book to be an invaluable reference.

Focusing on fundamental principles, Hydro-Environmental Analysis: Freshwater Environments presents in-depth information about freshwater environments and how they are influenced by regulation. It provides a holistic approach, exploring the factors that impact water quality and quantity, and the regulations, policy and management methods that are ne
