Multiple Phenomena of Debris-Flow Processes: A Challenge for Hazard Assessments
Hazardous hydraulic processes associated with arid environments commonly repesent significant risks to the safety of the public. However, the public generally considers these risks to...
Runoff and Erosional Processes in an Arid Watershed
This paper reports the results of geomorphic, hydrologic, and hydraulic analyses that integrated a physical process computer model of rainfall/runoff processes with a geomorphic process/response...
Soil-Moisture Flux Studies on the Nevada Test Site A Review of Results and Techniques
Over the last 20 years, numerous studies of soil-moisture flux and/or ground-water recharge have been conducted on the U.S. Department of Energy's (DOE) Nevada Test Site (NTS)...
Nitrate and Bromide Transport Through a Vadose Zone in New Jersey
Ongoing field experiments on monitoring transport of Sodium Nitrate and Potassium Bromide in the vadose zone over a shallow groundwater table in the coastal plains of New Jersey are discussed....
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...
A Value Engineering/Risk Analysis Approach to Operation and Maintenance of Hydraulic Structures
Value engineering is an objective, systematic method for minimizing cost of a system. Risk analysis is a method of quantifying uncertainties or probabilities of possible economic loss,...
Field and Model Studies of Ocean Outfalls
Field and laboratory studies of the behavior of wastewater discharged from the San Francisco ocean outfall are reported. Wastefield behavior was predicted by the mathematical models RSB...
Thermal Plumes from Staged Diffusers into a Uniform Quiescent Environment
The behavior of thermal plumes from staged multiport diffusers was investigated experimentally. The three-dimensional temperature distribution was measured by scanning thermistor rakes...
An Experimental Study of Oil Spreading in Ice Covered Waters
In this paper the experimental procedure and some preliminary observations from a new series of experiments on the mechanism of oil spreading under fragmented ice are presented. Laboratory...
Flow Distribution in Multiple Channels with Partial Ice Coverage
It is not uncommon for rivers to have multiple channels. The distribution of the total flow to the individual channels depends on their relative hydraulic characteristics of depth, width...
Modeling of Surface Vortices in Unsteady Flow
Hydraulic model studies of lock filling and emptying systems include investigating vortex tendencies at the intake vincinity during filling. The flow at the intake vicinity is unsteady...
Physical Modeling Study of the Niagara River Plume
A rotating laboratory facility is used to study the dynamics of the Niagara River discharge into Lake Ontario. The current tests are limits to buoyant discharge conditions, which occur...
Uncertainty of Runoff Volume as a Function of Rainfall and Catchment Characteristics
The expected variability of runoff volume due to the uncertainties in spatial distribution of rainfall and catchment characteristics is quantified. A physically-based mathematical model...
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...
Failure Modeling of Hydraulic Systems
Techniques of survival analysis are investigated for modeling the failure of hydraulic systems. The Proportional Hazards Model has the advantage of being able to separate the effects on...
