Gravel-Bed Rivers: Fluvial Processes, Engineering and Management

Abstract: A collection of papers by an international group of experts that clarifies the physical processes operating in gravel-bed rivers. Identifies engineering and management techniques based on natural flow processes to minimize the effect of river engineering and water resource development on river systems. Promotes improved design and modelling methods. Discusses future research requirements.

Analysis of Major Parameters Affecting the Behavior of the Mississippi River.

Abstract: : The present potamology program was initiated after the major flood of 1973, which confirmed that significant flood control capacity has been lost over a major portion of the lower Mississippi River. Objectives of the program are to obtain a better understanding of: the river's reaction to various parameters, why these reactions occur, and how to control these reactions and/or predict future changes resulting from them. The studies described in this report consisted of detailed investigation of four major parameters: hydrology, sedimentation, channel geometry, and man-made modifications. Of the four parameters studied, effective management of the sediment parameter offers the greatest potential toward achievement of a stable, dependable channel for both flood control and navigation. The second most significant parameter, one interrelated with sediment transport and storage, is channel geometry and alignment. Future potamology programs should focus primarily on the major objective of improving the balance between hydraulic parameters and sediment transport capabilities for a full range of flows, locally and throughout the middle and lower Mississippi River.
