Directional Wave Data ? Measurements and Modeling Coast of Florida Erosion and Storm Effects Study
The U.S. Army of Corps of Engineers, Jacksonville District, and the Florida Department of Enviromental Protection are co-sponsors of a study to evaluate the coastal processes along the...
New Technology in Coastal Wave Monitoring
The Coastal Data Informational Program (CDIP) is an extensive network for monitoring waves along the Pacific coastlines of the US. The system has evolved substantially since its inception...
Optical Remote Sensing of Wave Surface Kinematics
The measurement of the directional properties of surface slopes, velocities and accelerations is difficult, even in the laboratory, under conditions of steep, random and short-crested...
The Use of Crumb Rubber Modifier in Hot-Mix Asphalt
This paper summarizes the literature on the use of CRM as an additive in HMA. Wet and dry processes are discussed and the objective of each explained. Material, design and construction...
Removal Of Chromium From Groundwater Using Permeable Barriers: An Aquifer Simulation Study
Previous efforts to remediate groundwater contaminated by chromium-bearing industrial wastes have involved post-extraction methods, whereby groundwater is pumped to the surface treated...
Development of Hydro-Scheduling Model for Optimal Joint Operation of Multi-Reservoir Systems
Multipurpose reservoirs in a reservoir system are not limited to supplying ample amounts of water and electricity, but also provide other water demands such as flood control, navigation,...
Probabilistic Characterization of Droughts
The Palmer Drought Severity Index (PDSI) uses a set of meteorologic and hydrologic variables to create a numerical value for drought severity. The index values are grouped into drought...
Changing Dam Operating Criteria to Accommodate Aquatic Biological Diversity
The Colorado squawfish, bonytail chub, humpback chub, and razorback sucker, now threatened with extinction, were once the dominant fishes in the river. Recovering these native species...
Sustainable Management of Existing Reservoirs
Instead of a design and planning of new reservoirs in the future, more emphasis will be placed on the management of existing reservoirs. Reservoir storage reallocation and reassessment...
Integration of Reliability, Uncertainty and Optimization in Hydraulics Systems: Classification of Problem Types
Design and operation of hydraulic systems can be an extremely complex task. Although not widely accepted the application of deterministic optimization techniques can provide guidance to...
Impacts of Natural and Manmade Changes on the San Luis Rey River Environment
Almost all rivers continually change their position and shape based on various geomorphic and hydraulic factors, caused by natural as well as manmade activities on the riverine environment....
Building Groundwater Optimizers That Respond to the Needs of Decision-Makers
Optimization methods are being sought and employed to design systems that remediate contaminated groundwater regions (and, in fact, the subsurface in general) with increasing frequency....
A Physically Based Conceptual Model for Simulating Contaminant Levels in Subsurface Water
A conceptual physical model is developed to simulate solute transport and mixing in the vadose (unsaturated) and groundwater zones. The conceptual model couples lumped-parameters models...
Explicit Stochastic Modelling of a Reservoir for Hydropower Production
A new reliability model for planning the operation of a multipurpose reservoir for hydropower generation and flood control, which considers the stochastic nature of inflows and power demand...
Stochastic Optimal Control for Determination of Freshwater Inflows to Estuaries
The objective of the research is to develop estuarine system management models based upon discrete-time stochastic optimal control. An analytical feedback control law is given. The control...
Plate and Frame Membrane Air Stripping
This paper examines utilization of a plate and frame membrane air stripping system for the removal of volatile organic chemicals (VOCs) and radon from a water supply. Previous work explored...
Parallel SDP for Multi-Reservoir Management
The use of stochastic dynamic programming (SDP) for solving water resources problems has been restricted to problems with low dimension due to the 'curse of dimensionality'. Algorithm...
Evaluating the Steady State Stochastic Dynamic Programming Model for the High Aswan Dam
The paper describes the results of a study to critically evaluate and test the Steady State Stochastic Dynamic Programming model (SSDP). Whenever a reservoir computer model is developed,...
State and Resource Based Construction Process Simulation
Stroboscope is a programming language for construction process simulation. The programming language provides access to the state of the simulation and to the properties of resources. It...
Multi-Objective Optimization of Construction Schedules
This paper focuses on the multi-objective deterministic and stochastic modelling and optimization of construction tasks scheduling. Of particular importance is a frequency need to satisfy...
