Environmental Effects of Flooding at a USCG Base
In July of 1993, the U.S. Coast Guard (USCG) Base St. Louis facility was flooded. As the flood waters receded and cleanup efforts were initiated, a number of environmental issues had to...
Computing Two Dimensional Flood Propagation with a High Resolution Extension of McCormack's Method
McCormack's method, as applied for solving the bidimensional de Saint Venant equations is enhanced with the aid of the theory of Total Variation Diminishing (TVD) schemes in order to obtain...
A 2D numerical simulation of the Po river delta flow
A numerical simulation of the steady flow in the proximity of the delta of the Po river has been carried out. We consider the 2D quasi-hydrostatic model, approximating non conservation...
Quasi-Two Dimensional Modelling of Flood Routing in Rivers and Flood Plains by Means of Storage Cells
A quasi-two dimensional numerical model for flood routing in rivers and flood plains has been developed. In the river, the St Venant equations are integrated using the implicit finite...
Modelling of Flood Wave Propagation Over Flat Dry Areas of Complex Topography in Presence of Different Infrastructures
After a description of the general equations which govern the propagation of a 2D flood wave (shallow water equations), a review of the scientific publications on the integration of their...
Formation and Propagation of Steep Waves: An Investigative Experimental Interpretation
From the end of the last century, many Authors have studied experimentally the formation and the propagation of steep waves on dry flume bottom. Up to the present time, however, some aspects...
Free surface flow modelling on a complex topography
The aim of this paper is to describe the different construction stages and the validation of a free surface flow model on a complex topography. This model is based on the two dimensional...
Flood Propagation on Mobile Beds under Mountainous Flow Conditions
An implicit finite-volume scheme is used to solve the shallow water equations under mountainous flow conditions. The algorithm is stable for sub- and supercritical flows and moving internal...
Reliability and Validity of Modeling Sedimentation and Debris Flow Hazards Over Initially Dry Areas
Extreme floods may inundate populated areas of a river valley that are normally dry. Two-dimensional flow analysis is a useful method for predicting the spatial and temporal behavior of...
A comparison between computed and measured bed evolution in a river bend
A shallow-water scheme with a movable bed has been employed in order to check the reliability of computations related to the bed evolution when a substantially three-dimensional phenomenon...
Using Drop Structures for Stream Gaging
A long term monitoring program of 15 watersheds, for the purpose of studying channel response to erosion control measures being constructed in north Mississippi, is being conducted by...
A Computerized Open Channel Flow Measurement Device
This is a technical information paper with the intention of introducing a new product. It is not the intent of the author to use this as a marketing tool. However, it is the intent to...
Velocity and Turbulence Measurement from the Illinois and Mississippi Rivers
This paper presents a data measurement program that was used for collecting the velocity data associated with barge-tow traffic on the Illinois and Mississippi Rivers and includes a discussion...
Velocity Measurements by the One-Orange Method
Application of the most sophisticated instrumentation - so called state-of-the-art equipment - is not always necessary nor even desirable for measurement of mean velocities in verticals,...
Sediment Measurement Instrumentation A Personal Perspective
The development of the suspended sediment samplers in the 1940s was a major contribution to the science of sedimentation and provided for the proper development of dams, reservoirs, and...
An Investigation of Turbulence in Open Channel Flow via Three-component Laser Doppler Anemometry
A three-component laser Doppler anemometer is used to reexamine the distribution of single-point mean statistics in a nearly uniform fully-developed 2D turbulent open channel flow of water...
Experimental Study on Turbulent Structures in Unsteady Open-channel Flows
Turbulence measurements in unsteady open-channel flows over smooth beds were conducted accurately by the simultaneous use of two-component LDA system and water-wave gauges. In the inner...
Void Fraction Measurement Techniques for Gas-Liquid Bubbly Flows in Closed Conduits; A Literature Review
This paper provides a review of void fraction measuring techniques for gas-liquid bubbly flows in closed conduits with emphasis on the suitability of these methods for air-water bubbly...
Recent Applications of Acoustic Doppler Current Profilers
A Broadband acoustic Doppler current profiler (BB-ADCP) is a new instrument being used by the U.S. Geological Survey (USGS) to measure stream discharge and velocities, and bathymetry....
Experimental Study on Unsteady Flow in Open Channels with Flood Plains
Hydraulic characteristics of unsteady flows were investigated experimentally in open channels with flood plains using a computer-controlled water supply system. Some noticeable features...
