Way Against Debris Flows at China's Mountain Towns
For important protected objectives, the measures against debris flow in mountain towns should ensure all-round reliability and adopt a comprehensive system of engineering projects combined...

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...

Flood Control Improvements on Alluvial Fans
Floodplain management on alluvial fans has become an increasingly important issue with continued growth and urbanization in the southwest. The design of flood control facilities for new...

Risk Analysis as a Tool to Determine Spillway Design Capacities
Lyman Dam is an earth and rockfill structure located on the Little Colorado River approximately 11 miles south and upstream of St. Johns, Arizona. Several studies examining the safety...

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...

Identification Techniques for Bank Erosion and Failure Processes
The Hydraulics Laboratory of the US Army Engineer Waterways Experiment Station (WES) has developed techniques to design small flood-control channels. A component of this research is the...

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...

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...

Weibull Distribution and Natural Hydrograph
For design projects in water resources, a hydrograph is commonly used for the determination of flood volume generated by a given drainage basin. The division of total flow into direct...

Modeling a Large, Dynamic, Urban Drainage System
Impacts of progressive urbanization on peak streamflow are often difficult to quantify due to the dynamic, but subtle changes from year-to-year. In this instance urbanization impacts are...

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...

Application of the Generalized Channel Routing Model
Using the linear full dynamic finite difference model the applicability of diffusion and kinematic wave models is investigated. Two dimensionless numbers are suggested for applicable range...

An Investigation of Continuity Equation and Flood Routing
In this paper, a flood routing scheme, which gives consideration to the advantages of both the Muskingum method and the unit hydrograph method, is derived by using the continuity equation...

Paleoflood Hydrology and Design Decision for High-Risk Projects
Paleoflood hydrology is not merely one of several alternative methods for risk-based design. Rather, certain kinds of accurate data on the largest paleofloods of recent millennia provide...

Extraordinary Floods in Arid South Africa
South Africa, a country where 65% of the area receives less than 500 mm of rain annually, has experienced many major floods during the last century. The importance, aim and scope of the...

The Hydraulic and Hydrological Interactions Between Urban Sewer Systems and Receiving Waters at High Discharges
In the transition region from sewer to river, the penetration of river flood water into the sewer network or the hydraulic overload of small rivers due to sewer system discharges, may...

Urban Soft Bottom Low Flow Channel?A New Approach
In 1987, the City of Boulder, Colorado requested assistance from the Urban Drainage and Flood Control District (District) to repair an all too familiar problem of cattails growing in the...
