Stability Analysis of Optimal Active Control Systems with Time-Delay and Other Influence Parameters
This paper presents a theoretical solution for determining the stability region of multi-story buildings equipped with one active tendon controller on a certain floor. In this theoretical...
EPA's Environmental Monitoring and Assessment Program: Availability of Broad-Scale Environmental Data and Opportunities for Use in Environmental Modeling Applications
The Environmental Monitoring and Assessment and Program (EMAP) has collected a suite of environmental data over a four year period from estuarine systems in the mid-Atlantic and Gulf of...
Evaluation of Depth-Limited Wave Breaking Criteria
Numerous criteria exists for predicting incipient wave breaking. These criteria were verified with a limited number of data sets or under limited number of data sets or under limited beach...
The Determination of Typhoon Design Wave By Synthetic Probibility Method
In summer and autumn, typhoons always take place in the northwest pacific. in the northern hemisphere, the typhoon is a large, anticlockwise, atmospheric eddy. Due to the strong wind speed,...
Parameter Regionalization of a Daily Baseflow Runoff Model
Daily baseflow values are required to characterize the environmental measurements being carried out in several basins in the Province of Genova, northern Italy. The main purpose of these...
Evaluation of the Return Period of the September 1992 Flood in Genova, Italy
The September 1992 flood in Genova caused great damage and loss of life. The flood peak, at the outlet of a 12.5 km2 basin, was estimated at 200...
Determining Optimal Parameter Dimensions for Water Distribution Network Models
Water distribution systems contain a large number of pipes whose roughness factors are unknown prior to model calibration. During the calibration process, pipe roughnesses for each link...
Homogeneity Tests Based Upon Gumbel Distribution
This paper analyzes the performance of three homogeneity tests for Gumbel distributed flood flows. The classic Dalrymple test, a method-of-moment Cv test, and a normalized-quantile test...
Metamodeling Approach for Approximating the Operating Characteristics of Series of G/G/1 Queues on Congested Waterways
A simulation model representing waterway networks with queues at locks has been developed and validated. Functions developed from queueing theory were formulated to describe the operating...
A Theoretical Framework for Risk Assessment
This paper puts forth a theoretical framework for the development of any risk model. The focus is on the distinction between model and parameter uncertainty....
Behavioral, Social, and Institutional Aspects of Risk Analysis
The paper summarizes the third session of the conference which discussed four items that become pitfalls for decision makers when neglected. These are parameter uncertainties as distinct...
Recovery of Chromium from Spent Plating Solutions by a Chromyl Chloride Process
A novel chromyl chloride process has been investigated for the recovery of hexavalent chromium from spent plating solutions. In this process chromium is converted to chromyl chloride by...
Testing Turbine Aeration for Dissolved Oxygen Enhancement
During August of 1993 the Bureau of Reclamation tested turbine aeration for dissolved oxygen (DO) enhancement at Deer Creek Powerplant near Provo, Utah. This test required a variety of...
Spectral and Parametric Wave Models of Lake Erie
The GLERL-Donelan parametric wave model and the SHALWV spectral wave model are presently being used as modules of the Great Lakes Forecasting System in order to determine which best fits...
Estimation of Field Site Flow Parameters
The paper reports on the use of Kriging to obtain estimates of hydraulic conductivity underneath a rapid infiltration site. The parameters obtained were used in a two-dimensional groundwater...
Nonlinearity and Free-Surface Flow
The Dupuit-Forchheimer (D-F) assumption is commonly considered a viable design criterion for water resources projects and, consequently, Darcy law is used to determine the locus of free...
Real-Time Flood Forecasting Using Adaptive Estimation
The proposed flood forecasting system combines a flood routing model with a parameter estimation model. The flood routing model utilizes ?-index to determine the effective rainfall and...
Modeling of Maximum Velocity in Open-Channel Flow
A great deal of information about an open channel flow is contained in the maximum velocity, which, along with the entropy parameter, can determine the mean velocity. Therefore, the maximum...
A Lagrangian Model for Surface Buoyant Jets
A model is developed to predict the trajectory of a surface buoyant discharge into a large receiving water body. A Lagrangian approach is used to trace the path of a `control volume' of...
Evaluation of Six Methods for the LP3 Distribution
Six frequently used estimation methods for the Log-Pearson type 3 distribution were evaluated using both the predictive and the descriptive performance indices. Ten LP3 populations and...
