Prediction of Time Development of Local Scour
The prediction of the time development of local scour is commonly solved by means of model tests. A brief description of the time-scale and the relation between the time and the scour...
Flow Modeling in the Toutle River, Washington
In support of flow, suspended load, bed load, and bedform transport measurements, a quasi-three-dimensional river flow model was adapted to a reach extending from 260m upstream to 30m...
Mechanics of Mud Flows in Curved Channels with Uneven Beds
Most natural debris flows move through paths that are curved and that have significant bed topography. Owing to the dependence of the mechanics of wet debris containing substantial amounts...
Laboratory Analysis of Hyperconcentrations
The physical and kinematic behavior of hyperconcentrations has been reviewed and a summary of recent and past developments in hyperconcentrated flow research is presented. This paper focuses...
Settling Basin Model for the Personal Computer
The SETSIZE program, models sediment deposition in a settling basin. The program can be applied to determine the length of time until dredging or cleaning is necessary or solve for an...
Surface Roughness with Erosion of Earth Channels
A determination of the stresses effective in soil detachment is essential in determining erodibility. The soil roughness that exists during testing and in natural channels is a key element...
Sedimentation in Mud Mountain Reservoir at High Discharge
Mud Mountain Dam is a single purpose flood control project completed in 1948 on the White River in the State of Washington. The White River drains the northern and northeastern slopes...
Cold Regions Engineering
This volume contains papers that were presented at the 5th International Cold Regions Engineering Specialty Conference, sponsored by ASCE and held in St. Paul, Minnesota, February 6-8,...
Ports '89
This is a collection of the technical papers presented at the triennial Ports '89 Conference held in Boston, Massachusetts in May 1989. Authors, although predominantly from...
Application of Hydraulic and Sediment Transport Principles in the Design of Tidal Exchange Structures
This paper presents a procedure for the analysis and design of tidal exchange structures, such as tidal gates and training dikes. In lieu of over generalized theories or complicated modeling...
Single-Channel Alluvial Fan Hydraulics with Application to Design of Medium-Density Projects
Methods to identify flood hazards on alluvial fans are provided by the Federal Emergency Management Agency (FEMA) in their Flood Insurance Study, Guidelines and Specifications for Study...
Hydraulic Design of the Unser Boulevard Crossing
As an integral part of the design process, a comprehensive hydrologic, hydraulic and sediment transport analysis was completed of the proposed Unser Boulevard crossing of Calabacillas...
Partnership in Environmental Design for Brush Creek Flood Control
Brush Creek drains a highly urbanized area in metropolitan Kansas City. A large physical model was used to develop a channel modification design for flood control. The Parks and Recreation...
Regional Flood Plain Management
A flood plain management plan for White Rock Creek in the Cities of Dallas and Plano, Texas was developed. New technologies such as three-dimensional topography, CADD, and remote sensing...
Interfacial Instability in Highly Stratified Flows
The stability of highly stratified shear flows is dependent on several parameters including the thickness of the interfacial transition layer. Experimental results show that the thickness...
Experience with Cavitation in High Pressure Slide Gates
The Bureau of Reclamation has many years of experience in the design and operation of high pressure slide gates. This paper discusses the historical use of high pressure slide gates by...
Design, Construction and Testing of Repairs to the Low Level Outlets at Terzaghi Dam
Operation of the low level outlets (LLOs) at Terzaghi Dam in southwestern British Columbia resulted in severe cavitation at operating heads significantly lower than design. Modifications...
Extreme Flood Probability Estimates in Practice
Selecting the safety design flood for a dam or siting structures where flooding would cause severe social or economic disruption requires balancing the likelihood and consequences of failure...
The Estimation of Extreme Floods in Brazil
In Brazil, the design flood of a large dam is calculated using either the Probable Maximum Flood criteria or the 10,000-year Flood. Recently a Guidebook has been written to help Brazilian...
Effects of Climate Change on Watershed Runoff
This paper examines forecasts of changes in watershed runoff in the Delaware River basin that result from a range of predicted effects of increased atmospheric carbon dioxide (CO2)...
