Rainfall-Loss Parameter Estimation for Illinois
The U. S. Geological Survey is currently conducting an investigation to estimate values of parameters for two rainfall-loss computation methods used in a commonly used flood-hydrograph...
Remote Sensing Applications in the Model of Runoff Formation in Excess of Storage
The model of runoff formation in excess of storage applied in some humid regions of China is revised in this paper, so that the model can adopt the information provided by Landsat remote...
A Robustness Constraint for the Analysis of Uncertainty
A sensitivity-based definition of system robustness is presented that can be formulated as a constraint within an optimization framework. The optimization framework permits the tradeoffs...
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...
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...
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...
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...
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...
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...
Prior Information in the Geostatistical Approach
An overview of recent work on the geostatistical approach to the inverse problem of groundwater modeling is presented. A method which allows utilization of prior information about the...
Basalt System Characterization: Inverse Technique
The Basalt Waste Isolation Project (BWIP) has been established to assess the feasibility of the Columbia River Basalt Group as a host medium for a high-level radioactive waste repository....
Parameter Identification in Water System Models
Parameter identification (PI) is an automatic model calibration technique with which the unknown physical parameters in a mathematical model are determined from a constrained optimization...
Optimal Muskingum River Routing
The Muskingum method of river routing is well established and frequently used. An attempt is made to improve the method by optimal selection of the model parameters. The common linear...
Optimization Issues in the Design and Control of Large Space Structures
The optimization and identification issues which arise in the design and control of large flexible space structures are reviewed. The first paper examines the use of several different...
Water Quality Impacts From a Flood Control Reservoir
Both qualitative and quantitative approaches were used to evaluate the impact of a flood control reservoir located on the Des Moines River in central Iowa on seven water quality parameters:...
Teaching Open Channel Design with Programmable Pocket Calculators
The goal of the basic open channel flow course is to present the theory of steady flow of water in open channels and some channel design practice. This paper presents the evolution of...
Predicting Overland Flow and Infiltration
The kinematic overland flow and the Green-Ampt infiltration equations are coupled and rewritten in terms of several nondimensional parameters. Constant values of these parameters imply...
Encoder for Flood and Irrigation Data Transmission
This paper covers the design and use of a new dual parameter encoder for real time telemetry in the fields of flood forecasting and irrigation. Some history and background is presented...
Two-Parameter Synthetic Unit Hydrograph for Microcomputer Application
A regression model was developed for estimating the unit hydrograph for ungaged watersheds. The model uses physical characteristics of the drainage basin to predict the parameters needed...
Modeling Aquifer Sensitivity and Leachate Controls
This paper investigates the transport of waste leachate from a leaky containment facility using the computer model of Two-Dimensional Solute Transport and Dispersion in Ground Water developed...
