Economics of Ditch Maintenance in Northwestern Ohio
A history of drainage and settlement in the Black Swamp of Northwestern Ohio is presented. The Ohio Ditch Law and county ditch maintenance program is explained. An economic comparison...
The Utilization and Protection of Coastal Land
Coastal land is defined as the strip of land which extends seaward to the spring low tide line and landward to about 20km distance from shoreline in Jiangsu, China. The emphasis in this...
Risk Analysis for Ship-Bridge Collisions
The authors have developed a propriety software package which has been successfully used to perform risk analyses for several high-level bridge structures across major waterways in coastal...
Microcomputer Simulation of Jets and Wakes
Illustrations are presented for radial jets and for turbulent flows in the wake of circular cylinders. The paper illustrates the use and importance of low-cost computational tools in engineering...
Computer-Based Predictions of Atchafalaya Bay Sedimentation
The Atchafalaya River, a distributary of the Mississippi River, discharges into Atchafalaya Bay through the Lower Atchafalaya River and Wax Lake Outlet. The bay delta has grown rapidly...
Simulation of Wetland Hydrology and Hydrodynamics
The relative changes in water stage in swamps and marshes and the variations of current velocities in bayous and canals under present conditions are calculated, using a computer watershed...
A Shoppers Guide to Urban Stormwater Micro Software
Due to limited information provided by the ads, potential users may need to call or write to several vendors (or perhaps even purchase several packages) before finding one to meet their...
Interactive Computer Aided Graphic Water Well Pumping Test Evaluation Software
A microcomputer software package was developed which allows the user to interactively evaluate pumping tests using semilog and log-log graphic methods for time-drawdown, step-drawdown,...

Analyses of Sediment Transport Data by Microcomputer Software
The MINITAB statistical software project has been popularly used on mainframe computers since 1972. In June 1984, a subset of the program was made available for the IBM-PC microcomputer;...
Computer-Assisted Problem Solving in Hydraulic Engineering
A number of practical hydraulic problems may be solved using software that allows interaction at the equation level rather than through higher level languages. This paper presents examples....
Near Real-Time Climatic Data in Illinois
The need for making real-time climatic data available for use was recognized in Illinois, and a concerted effort began in 1983 to develop a system for collecting and disseminating near...
The Possibility of People Mover Cost Reduction in Japan
