Effect of Bridge Pier Shape and Contraction Ratios on Backwater Profile

Bridge Abutment Scour in Floodplain with Backwater

Flow Transitions in Bridge Backwater Analysis

Modeling Ice-Covered Rivers Using HEC-RAS

Influence of Backwater on Headcut Advance
A study was performed to examine the influence of backwater level downstream of an overfall on headcut advance. The discharge, overfall height, and soil type were held constant while varying...

The Effects of Water Surface Profiles on Manning's Roughness Coefficient
The Manning Equation has wide application in engineering practice. Nonetheless, certain aspects of it are still not widely understood. Often, engineers deduce the value of Manning's...

Estimating Sediment Conveyance Capacity and Deposition Potential in Culverts
In watersheds characterized by high sediment production, culverts must be designed to adequately convey both water and sediment without causing excessive backwater upstream of the culvert...

Effect of Bridge Pier Shape and Contraction Ratios on Backwater Profile

Impacts of the 1993 Flood on the Mississippi River in Illinois
The 1993 flood has now been recognized as one of the greatest floods on the Mississippi and Missouri Rivers. Its geographical extent included portions of Iowa, Missouri, Illinois, Wisconsin,...

Weaver Bottoms Backwater Rehabilitation
Navigation channel dredge material was used to construct closure structures and islands in lower pool 5 on the Upper Mississippi River in 1986. Primary objectives included aquatic habitat...

Hydraulic and Geomorphic Classification of the Upper Mississippi River System: Pilot Study of Three Pools

Stability Problems in Stream Water Profile Computations

Flood Hazard Scenarios in a Pleistocene-Holocene Basin
Technical scenarios are used to characterize the flood hazard in the Bayou Fountain Basin, an area of complex geomorphology and urbanization. Floods from three sources, 1) local precipitation,...

Hydraulic Aspects of Grade Control Structures
This paper describes the function of grade control structures. The primary purpose of a grade control structure is to maintain or establish a desired bed elevation in a channel. Basically...

Ultrasonic Velocity Meter Used in Stream Gaging
Many streams and canals in Florida are affected by tides or control structures and experience very low flow velocities at times. For example, the St. Johns River in northeastern Florida...

Sediment Sources Analysis for Peoria Lake Along the Illinois River
The modern-day lower Illinois River flows within a greatly oversized valley formed by an old course of the Mississippi River and glacial outwash events. As a result, the section of the...
