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...
Effect of Data Sampling Time Resolution on Probability Distribution of Elapsed Time Between Rainfalls
The elapsed time between rainfalls is useful information in statistical forecasting of rainfall and runoff. The probability density function (pdf) of the elapsed time can be determined...
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...
Some Benefits of Grid by Number Sampling
Describing the overall sediment composition of gravel-bed river reaches and depositional bars is a difficult problem due to spatial variations in the sediment size. Past research has focused...
3D Free Surface Flow Model Verification - A Panel Discussion on Test Cases
This paper is to briefly present the objectives and approaches of the Panel Discussion on test cases to be developed for 3d free surface flow model verifications, so that professionals...
Estimation of Design Surge Heights by Utilizing Meteorologic and Oceanographic Data
Data on cyclonic storm surge height have been generated with the help of a statistical simulation model. Data on observed maximum cyclonic wind speed and the length of the continental...
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...

Estimating Network Model Parameters from Mail Survey Data
Network models are generally based on a four-step modeling process; trip generation, trip distribution, modal split, and trip assignment. Microcomputer implementations of these steps have...
A PASSER II-90 Postprocessor for Detailed Analysis of Arterial Traffic Control Parameters
Many preprocessors have been developed for traffic signal operation software to ease the tedious data input process or to perform error trapping on the input data. However, work to date...
Factors Controlling Strong Ground Motion and Their Associated Uncertainties
Of special interest in strong ground motion modeling is a quantification of the degree of influence specific physical parameters have on the computed motions. Associated with the model...
New Methods to Characterize Site Amplification
Methods alternative to spectral ratios are introduced to characterize site amplification. The methods are developed by using a range of models, from the simple constant amplification model...
Fatigue Damage Accumulation Under Non-Gaussian Loads
The stochastic fatigue life prediction method, namely the Rayleigh approximation method, is almost exact when the loading is both normal (Gaussian) and narrowband. However, in many realistic...
Results from the Second Performance Assessment Iteration for the Greater Confinement Disposal Facility
The Greater Confinement Disposal (GCD) facility was established by the Nevada office of the Department of Energy (DOE) in Area 5 at the Nevada Test Site for containment of waste inappropriate...
Flow and Transport in Hierarchically Fractured Systems
Preliminary results indicate that flow in the saturated zone at Yucca Mountain is controlled by fractures. A current conceptual model assumes that the flow in the fracture system can be...
Automatic Calibration of 3D Finite Differences Model Parameters? Application to the Finnsjon Site (Sweden)
Calibration of 3D finite difference model parameters is usually carried out using a noon-automatic 'manual' procedure until observed heads, for instance, are simulated with a sufficient...
The Best of Both Worlds: Integrating Statistical and Deterministic Approaches to Area Remediation
We seek a complete framework for adaptive area characterization for purposes of remediation, incorporating both statistical and deterministic features. This hybrid methodology involves...
