Multivariate Modeling of Hydrological Time Series for Generation of Reservoir Operating Rules
A multivariate model and a disaggregation model are used in this study to generate annual and monthly time series of streamflow data for multiple sites. The parameters of the models are...
Simulation Models of Sequences of Dry and Wet Days
A new statistical model has been developed for the simulation of sequences of dry and wet days. The model is based on the discrete autoregressive-moving average (DARMA) family of stochastic...
Uncertainty and Conservatism in the Seismic Analysis of Nuclear Facilities
Traditionally, seismic analysis and design of nuclear power plant structures are performed using deterministic procedures. In order to address the issue of the likelihood of failure, probabilistic...
Statistical Analysis of Tellico Dam Piezometer Data
The purpose of this paper is to demonstrate the use of statistical and computer processing methods as a tool for analyzing dam safety piezometric monitoring data. Statistical methods are...
Real Time Data Acquisition in Structural Testing
The process of data collection in real time for structural engineering can be generalized into a process called the real time sequence. The sequence has three major phases: preliminary...
Computer Errors?Who's Responsible
This paper proposes that both the program developer and the program user share the responsibility for preventing errors in the use of computer programs for engineering design and analysis....
Three Inexpensive Land Use Allocation Techniques
The current thrust in transportation planning is to make use of manual and microcomputer techniques for providing quick-response travel estimation. In this context, matching land use techniques,...
Modeling Human Error in Structural Design and Construction
Human error is recognized as the major cause of structural failure. Moreover, it may greatly exacerbate the damaging effect of other hazards, such as earthquakes. The objectives of this...
Issues and Challenges in Transit Performance Research
Using performance indicators as a management tool in the transit industry is a developing art. Three theoretical issues have deterred progress: disagreement over definitions of efficiency...
Assessing Infrastructure Alternatives?Atlantic City Style
As with most older American Cities, the originally installed infrastructure was not designed to meet the increased demands of today. Time has seen the creation of many separate but yet...
In Situ State of Underwater Hydraulic Sand Fills
An approach is described for quantifying the in situ state of hydraulically placed sand fills which are a significant element in the construction of artificial exploration islands in the...
Spatial Analysis of Ice Charts
Spatial approaches to ice environment modeling can not only lead to better local hazard predictions but also produce regionalizations that are useful for construction, navigation, and...
MILHY?A Microcomputer Based Hydrologic and Hydraulic Model
MILHY is an interactive, single event, lumped parameter model used to estimate streamflows and water surface profiles. The model was designed for use on basins less than approximately...
Classification of Human Errors
Error control should be a primary part of any risk control strategy. Classification of errors may serve as a basis for the systematic analysis to eliminate the causes and to reduce the...
Simulation of Airborne Snow Water Equivalent Measurement Errors Made over a Forest Environment
The Office of Hydrology of the National Weather Service has developed and maintains an operational Airborne Gamma Radiation Snow Survey Program in the upper Midwest (Peck, et al. , 1980)....
Prediction of Soil Water Properties for Hydrologic Modeling
Water flow in soils can be characterized for many boundary and initial conditions by solving governing differential equations. Thus, a physically consistent means of quantifying water...
An Application of Probability to Rock Slope Design
This paper describes the use of probability and statistics in the slope design process. An example is presented of a high rock slope in an open pit mine. This slope is a major concern...
A Combined Limit Equilibrium and Statistical Analysis of Wedges for Design of High Rock Slopes
This paper describes a unique technique developed for the statistical analysis of wedge failures which control the design of high slopes in relatively hard jointed rock masses. Using this...
Fracture Mechanics Analysis of Massive Hydraulic Fracturing Containment
The hydraulic fracturing containment problem is the subject of the present investigation. Unlike previous studies, the interface crack geometry with the correct crack tip singularity was...
Stochastic Modeling of Mean Areal Precipitation for Generating Synthetic Streamflows
Statistical precipitation models used as input to conceptual hydrologic models, offer an alternative mechanism for simulating streamflow. In sparsely gauged catchments, or areas where...
