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...
Design and Construction of Soil-Cement Drop Structures
Soil-cement has been used as an effective and economical slope protection material for embankment dams and stream banks. This paper describes the use of soil-cement in the construction...
Innovative Spillway Design
The Lake Alan Henry Dam, near Lubbock, Texas, will consist of an earth filled embankment, a service spillway and an emergency spillway. The service spillway is designed to handle flows...
Characteristics of the Flood Release-Induced Vibrations with Qianshui Thin-Arch Dam
In this article the prototype observations and design analyses are described regarding the flood release-induced vibrations of the Qianshui thin-arch dam and its foundation; and their...
Pump Selection Program and a Better User Interface
Numerous highly innovative computer solutions to engineering problems are of little use to the practicing engineer because these programs are not supported by adequate user interface....
Compact Pump Sump Design
This paper details the design criteria chosen to construct a pump sump within several on-site constrictions. The physical size restrictions of the site necessitated the construction of...
Stabilization of an Alluvial Channel in an Urbanized Area
Grade stabilization structures have been used for many years to control degradation of alluvial stream in the southwest. These structures result in reducing the gradient of the stream...
Aeration of a Submerged Jet-Flow Gate
Submerged operation of a jet-flow gate requires special treatment of the area downstream from the gate to avoid cavitation damage. The Bureau of Reclamation studied operation of a submerged...
Sediment Management with Submerged Vanes
Submerged vanes are small river training structures used for protection of streambanks against erosion and for amelioration of shoaling problems in navigation channels, at water intakes,...
Intake Wheel Gates Sealing Arrangements
This article discusses the sealing arrangements for intake wheel gates. Advantages and disadvantages if upstream and downstream sealing arrangements including thier effects on the performance...
Hydraulic Modeling of Flow Control Gates
Flow control gates are subject to complex hydrodymanic loadings, which may in many cases only be predicted through investigation on a physical hydraulic model. Scaling of gate models,...
Ring Gate as Turbine Emergency Shut-Down Device
The ring gate, intially used as a regulating device in the early stage of the design of hydraulic turbines, has grown to a reliable emergency shut-down device. Incorporated in the hydraulic...
Chute Design Using Concrete Building Blocks
Chutes constructed using concrete building blocks for erosion control on ephemeral streams have performed successfully. The chutes consist of a layer of blocks placed on a geotextile over...
