Several methods of extremal wave analysis have been applied to two sets of deep water extreme wave data. One set consisted of three-hourly sea-state records collected during a nine year...
Implementation of Elastic Layered Theory for Design of Unbonded Overlays
The U.S. Army and Air Force have implemented the elastic layered theory for design of unbonded overlays for rigid airfield pavements. The procedure allows for design of unbonded overlays...
Airports and Air Quality Issues - the European Perspective
This paper presents a detailed review of air quality studies at European Airports since 1986. It also provides a brief analysis of the air quality section of a recent ACI (Europe) environmental...
The Effects of Spatial Resolution in Modeling the North Fork Drainage of the Gunnison River Basin
The U.S. Geological Survey Precipitation-Runoff Modeling System (PRMS) is a modular, distributed-parameter, watershed modeling system developed for use in evaluating the effects of climate...
Reservoir Operation Using Bayesian Inferencing and Balancing Rules
The water resources problem addressed in this paper is real-time, multi-purpose reservoir operation. Specifically, daily, or at the most, weekly operations are considered. A hybrid modeling...
Evaluating Sensitivity of Hydraulic Control Optimization Models
Sensitivity of hydraulic control optimization models to variation in gradient constraints is examined. Monte Carlo simulation is used in conjunction with repeated optimization runs to...
