Riprap Stability on Channel Slide Slopes
The stability of riprap placed on a sloping bank is decreased because one component of gravity tends to displace the rock down the slope. Results of riprap stability tests on sloping banks...
Design Considerations for Hydraulic Jump Structures
The primary purpose of this paper is to define the areal distribution of large-scale pressure pulses acting on the containment structure of a hydraulic jump. The results presented are...
Hydraulic Structures on Piles
Many hydraulic structures built in the early 1900's were founded on piles. Today, when these structures are analyzed as 'pile-supported', the analyses...
Dam Safety Improvements for Tolt River Dam
Studies were performed to identify measures to improve the safety of the project under earthquake and extreme flood conditions while permitting the owner to store additional water under...
Underwater Inspection of Hydraulic Structures
Improvements in diving equipment, and underwater testing and instrumentation devices in recent years have increased the value of underwater inspections and reduced the cost. This paper...
Parametric Analysis of Concrete Gravity Dams using Finite Element Analysis
More sophisticated means of analyses have been investigated to determine the accuracy and applicability of conventional methods to a range of parameters affecting stability. This paper...
Scour Downstream of High Level Emergency Spillways
The Corps of Engineers has numerous high level emergency spillways (HLES) including some that have the potential for excessive scour downstream during certain flow events. 'Excessive...
Low Head Dam Safety Studied with Hydraulic Models
Use of physical models to study the hydraulic jump or submerged roller action created as water overflows low head dams provides an opportunity to develop design criteria for various structure...
Modeling Materials for Protecting Earth Weirs
This paper reports laboratory experiments on various materials used to protect earth weirs. Dumped rock, gabion mattresses, and shaped blocks on a gravel layer were subjected to high velocity...
Reinforcement of Steep Grassed Waterways
A collaborative research program has been undertaken in the UK to develop guidelines for the use of various proprietary reinforcement systems to enhance the erosion resistance of grass...
Design of Overtopping Protection for Small Dams
Many existing small embankment dams in the United States cannot safely pass current design floods without overtopping. In the past several years, embankment overtopping protection has...
Hydraulic Model Investigation of the North Diversion Structure, Albuquerque, New Mexico
The North Diversion Structure diverts storm runoff around Albuquerque, New Mexico. Observed flow conditions have caused concern about the capacity of the structure and the safety of a...
Input Programs for Engineering Applications
This paper discusses several input program types and the data structures associated with them. Two input programs were designed for KYPIPEF to demonstrate the use of files of records and...
Numerical Model Analysis of Sedimentation Problems at Lock and Dam 1, Red River Waterway
This paper addresses the numerical modeling techniques used to identify the conditions and parameters affecting sediment deposition at Lock and Dam 1. Two-dimensional finite element models...
An Analysis of Channel Stability of the Red River from Shreveport, Louisiana to Index, Arkansas
To analyze the stability of the Red River in the study reach (Shreveport, LA to Index, AR) two comprehensive hydrographic surveys were studied. The hydrographic surveys were compared to...
Flood-Control Channel Stability Assessment
Guidelines for conducting a stability assessment of a channel proposed to be modified for flood control are presented in this paper. The basis behind this assessment is that a channel...
Response of a Lake Outlet Channel to Dredging
Channel improvements were completed in 1982 along approximately 8 miles of the Little Tallahatchie River just downstream of Sardis Dam. Heavy rains shortly after completion of the improvement...
Development of a Monitoring Program and Vegetative Restoration Project in a Mississippi River Bendway
The Dry Bayou-Thompson Bend area is located on the right descending bank of the Mississippi River between river miles 4. 5 (7. 2 kilometers) and 30. 0 (48. 3 kilometers) above the confluence...
Stream Width Adjustment to Upstream Loading
Channel width adjustments takes place either by fluvial erosion or accretion of the banks, or by their mass failure under gravity and subsequent removal of the slump debris. Simulation...
Diversion Structure for Peak Flow Reduction
The flood control requirements of a planned development in the City of Orange, California were such that the peak discharges ranging from an annual flood up to 25-year return period be...
