Design of Steel Transmission Pole Structures
Comparison of Design Rainfall Criteria for the Southwest
The design of drainage and flood control facilities or the management of floodplains for alluvial fans is extremely sensitive to the design rainfall criteria that is used as input to the...
Inclusion of Wetlands in Designated Floodway Studies
The purpose of this paper is to propose a change in the traditional methods and procedures used by hydrologist and hydraulic engineers to define floodways and floodway fringe areas. We...
Mudflow Rheology in a Vertically Rotating Flume
Joint research by the U.S. Geological Survey and the University of Missouri-Rolla currently (1990) is being conducted on a 3.05 meters in diameter vertically rotating flume used to simulate...
Rheological Properties of Simulated Debris Flows in the Laboratory Environment
Steady debris flows with or without a snout are simulated in a 'conveyor-belt' flume using dry glass spheres of a uniform size, 5 or 14 mm in diameter, and their...
Unsteady Flow of Bingham Viscoplastic Material in an Open Channel
An analytic solution for transient flow of a Bingham viscoplastic material in an open channel is presented. The solution for the response to a time-varying pressure gradient predicts shear...
Predicting Stream Width and Bank Retreat
The width of streams is dependent on the flood flow discharge which varies from year to year, the bank material which varies from stream to stream and reach to reach, the sediment load...
Hydraulic Bridge Design for Movable Bed Conditions
This paper addresses the practical considerations of hydraulic design of a bridge under movable bed conditions. Hydraulic design tasks include pier and abutment scour calculations, design...
Alignment of Large Flood-Peaks on Arid Watersheds
Bridge and culvert design requires estimates for 25- to 100-year return period flood peaks (Q). Floodplain delineation calls for 500-year (Q500) estimates. Arid western flood series are...
Resistance Consisting of Both Viscous Force and Dispersive Force
A set of specially designed experiments have been carried for studying the resistance of a flow consisting of water and both fine and coarse particles. The viscous force caused by fine...
Graphics Advances Aid Flood Engineers
In the last decade options have been suggested to the Log-Pearson III (LP3) computation for predicting design flood behavior in semi-arid conditions. Observations from an ongoing study...
The Sorry State of Flood Hydrology in the Arid Southwest
Flood hydrology for urban areas of the arid and semiarid Southwest is in a sorry state. It is based in large part on precomputer manual methods. The state-of-the-art should move into the...
Design Storms and Sizing of Flood Control Facilities
Design stroms which embody the rainfall characteristics of an area are used for the sizing of drainage facilities. The selection of a design strom may significantly influence the design...
Example of the Stable Channel Design Approach
This paper shows an example application of a new method being packaged by the US Army Engineer Waterways Experiment Station to aid in the design of stable flood-control channels. A stable...
Environmental Design of Channels?Can It Be Done?
The importance of environmental features to channel design is generally accepted and procedures for incorporating environmental features into flood control channel design have been developed....
Stable Channel Analytical Design Method
The Flood-Control Channels Research Program is being conducted at the US Army Engineer Waterways Experiment Station to develop systematic methods for design of stable channels for small...
Guidance on the Selection and Use of Sediment Discharge Formulas
The purpose of this paper is to discuss the sediment function module of the computer program SAM. SAM is being developed as a product of the US Army Corps of Engineers Flood Control Channels...
Optimal Design of Highway Drainage Structures
Hydraulic design of a bridge or culvert using a risk-based approach is to choose among the alternatives the one associated with the least total expected cost. In this paper, the risk-based...
Conservativeness in Hydraulic Engineering Studies
Hydraulic engineers routinely make a variety of assumptions during the course of a study. Assumptions, once made, usually become incorporated into the fabric of the study and are seldom...
Riprap Stability Results from Large Test Channel
Velocity data from a large test channel were used to determine the distribution of depth-averaged velocity and shear stress on the side slope of both straight and curved channels. From...
