Applications of Spreadsheets in Water Resources
This paper describes two applications of the spreadsheet MULTIPLAN to water resources problems. Applications include statistical analysis of water resources data and design of a stormwater...
Data Transforms on USGS Surface Water Records
Surface water records compiled and stored by the United States Geological Survey (USGS) on machine readable tape are transformed and analyzed by computer methods to enable visual inspection...
Real-Time Data Verification
Recent improvements in the real-time acquisition of hydro-meteorological data have raised concerns regarding the quality of the data received. Water users having practically instant access...
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...
Deterministic and Statistical Water Quality Modeling
An integrated methodology is presented, based on a hierarchical package of computer models ranging from simple micro-computer programs to more complex mainframe simulation, to address...
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...
Risk-Cost Analysis and Spillway Design
The NRC's recent report on dam safety proposes risk cost analysis to help select among alternative spillway modifications for existing dams. This paper examines the sensitivity...
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...
Quantifying the Exposure
Methods of categorizing and modeling of exposure will be presented. The use of modeling for the estimation of population exposure will also be examined and some errors inherent with such...
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:...
Evaluation of Cloud Seeding: Southern Great Plains
One of the important aspects of planned weather modification in the United States is that many operational, non-experimental cloud seeding projects have occurred since 1950. Further, several...
The Statistics of Storm-Induced Sediment Resuspension
The passage of a storm increases the wind stress applied to the sea surface. This surface stress is partially dissipated as it is transmitted through the water column. Some fraction of...
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...
A Microcomputer System for Processing Analog Hydrologic Data
Microcomputer software was developed to digitize, filter, and view data from analog charts of gate operation and water level before being transmitted to a mainframe computer for data base...
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...
Modeling Hydraulic Problems Using the CVBEM and the Microcomputer
The Complex Variable Boundary Element Method (CVBEM) offers an effective and efficient means for modeling two-dimensional potential and related flow problems. The method has been applied...
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...
