Weathering Steel Bridges — State of the Art
State of the art dissertations on materials that have been in commercial use for over a century are not likely to illustrate major new and innovative breakthroughs. Instead, the state...

Development of Skewed Element for the Concrete Pavements
In the recent years, highway engineers introduced skewed joints in the concrete pavement with a 4 foot to 5 foot skew on a 24 foot width pavement, which results in only one wheel crossing...

Weathering of Constituents at Land Treatment Sites
The objectives of this research were to: 1) determine the leachability of metals and organics from soils at hazardous waste land treatment sites; 2) evaluate the mobility of hazardous...

Potential Non-Traffic Benefits from a New Highway
The State of Delaware is now in the design/build phase of a major north-south relief highway. Expedient action included an Environmental Impact Statement adequate to show that the project...

Advisory System for South Florida Water Management
A comprehensive, real-time advisory system was developed for the operation of water control facilities within the South Florida Water Management District. The Operations Assistant and...

Development of the Hydrodata CD-ROM Data Storage System
To store and retrieve data from two of the USGS WATSTORE databases - the daily and peak values files - and the Summary of the Day file from the National Climatic Data Center, the authors...

Flood Warning Using Wide-Area Computer Networks
Wide-area computer networks are being used with increasing frequency to improve regional response to flood events, coordinate efforts between agencies and communities, and to improve flood...

Simulation Model for Economic Irrigation Project Planning and Design
The principle design parameters considered are: water supply configurations (quantity, source and storage); shapes and sizes of the area to be served; on-farm irrigation techniques; cropping...

A Method to Treat Incident Wave Condition in Shallow Water Equation
A method to consider open boundary condition of the shallow water equation to analyze water surface wave and tide is employed in the finite element anaysis. This can be done by considering...

Two Dimensional Nonequilibrium Transport of Nonuniform Sediment
Mathematical models based on diffusion and/or diffusion convection equations have been widely applied to study sediment transport in suspension. Some of the studies were reported by C.C....

Boundary Conditions of Tidal Model at River Mouth
A small grid is required to schematize irregular shape of shoreline in the vicinity of river mouth which limits the modeling area to be small. Tidal records along the boundary show no...

Determining River Stages with Consideration of Backwater Effects
In a recent hydraulic investigation on the Cache River basin, the stages of the Mississippi River at the Beechridge station were found to be necessary downstream boundary conditions for...
