Infrastructure Condition Forecasting Using Neural Networks
Condition forecasting models are critical components of any infrastructure management system. infrastructure condition assessed through periodic inspections which assign ratings to various...

Longshore Sediment Transport and Radionuclide Dispersion in the Black Sea Coastal Zone
After the Chernobyl accident the studies of the longshore sediment transport in the Black Sea have got new applications connected with a marine pollution problem. The method to calculate...

Recent Bentthic Foraminifera as a Sedimentation Tool in the Nigerian Coastal Environment
The ratio between the living and total populations of benthic foraminifera has been shown to be useful in determining relative rates of sedimentation in paralic and marine environments....

Aeolian Sediment Transport Under Offshore Wind Conditions: Implications for Aeolian Sediment Budget Calculations
Field studies of aeolian sediment transport on natural beaches reveal measured transport rates that are lower than those predicted by existing equations developed in arid environments...

The Use of a Flood Damage Rating System to Aid Urban Stormwater Management
Increasing urbanisation and the subsequent decrease in natural storage and infiltration potential in a catchment, cause increased runoff peaks and volumes. Existing stormwater drainage...

Applicability of Gabion Dams for the Control and Release of Storm Water Runoff

Reactive Irrigation Scheduling for Sloping Furrow Irrigation
We developed a technique for estimating the proportion of the applied irrigation water that is effective when using furrow irrigation. To apply the method, irrigators would need to know...

BASIN 2.0 for the Design of Level-Basin Irrigation Systems
The purpose of this paper is to present a computer program for the hydraulic design of level-basin irrigation systems. The first of three design modes provides design based on the advance...

Streamflow Depletions and Water Transfers in Idaho
In the state of Idaho, streamflow depletions are quantified utilizing parameters of rate of flow, total volume diverted, and volume consumptively used. This paper summarizes the engineering...

New Jersey Bridge Scour Evaluation Program
The New Jersey Department of Transportation has undertaken an ambitious scour evaluation program for the existing waterway bridges in the state. The methodology developed and utilized...

Repeatability and Oblique Flow Response Characteristics of Current Meters
Laboratory investigation into the precision and accuracy of various mechanical-current meters are presented. Horizontal-axis and vertical-axis meters that are used for the measurement...

Selecting Sediment Transport Equation for Scour Simulation at Bridge Crossing
Gravel transport formulas were tested in order to select a formula for simulating stream channel changes of Stony Creek in northern California. At a stream reach undergoing scour, the...

Reliability Analysis of Levee System of a River
The levee height is determined by the summation between computed water level and an assumed freeboard. The water level is computed by given discharge in the steady conditions. Therefore,...

Level of Service in Bridge Management Systems
The Federal Highway Administration's Sufficiency Rating is not adequate for evaluating bridges. It ignores fundamental bridge characteristics and is far too subjective. The Level of Service...

Water Leakage through Cracks in Reinforced Concrete

Evaluation of Runway Roughness for Fighter Jets
A new roughness evaluation procedure is needed, especially, when dealing with modern fighter jets. To this end, a comprehensive pilot attitude survey was conducted in Israel in order to...

In Search of Better Load Ratings
Typically, engineers must make a number of subjective assumptions regarding loading and response behavior when they develop a load rating for civil structures. As a result, many unknowns...

One and Three Dimensional, Three Phase Deformation in Soil
An initially saturated soil exhibits two distinct deformation patterns as it drys. First, it deforms vertically until the soil begins to drain. Secondly , it deforms laterally as well...

Permeability Determination for Unsaturated Soils
A reliable approach for the determination of the soil hydraulic conductivity function relies on the parameter estimation solution approach in which heterogeneous state of saturation within...
