Evaluation of a Bias Aware Ensemble Kalman Filter Using a Scaled Aquifer Transport Experiment
In this study, a bias-aware Ensemble Kalman Filter (EnKF) is applied to a scaled aquifer transport experiment (1-cm of the model equals 1-m at field scale and 1-day of model transport...

Advances in Watershed Management and Fluvial Hazard Mitigation Using Artificial Neural Networks and Remote Sensing
Watershed and channel management across spatial and temporal scales requires an informed, interdisciplinary approach by experts and stakeholders, who often have disparate goals and objectives....

Geo-Frontiers 2005
These Proceedings showcase recent advancements in all facets of the geo-industry. Geo-Frontiers was conceived to present the frontier of civil, geotechnical, and geoenvironmental engineering....

Analyzing Sediment Dynamics Post Dam Removal: One Size Does NOT Fit All!

Guidelines for the Testing of Seismic Isolation and Energy Dissipating Devices
This report outlines the HITEC Technical Evaluation Plan for seismic isolation and energy dissipating systems. The plan is designed to characterize the fundamental properties and performance...

Modelling of Displacement Piles in Sand Using a Pressure Chamber

Analysis of Dynamic Laterally Loaded Pile in Clay
Deflections of laterally loaded pile groups are strongly affected by the degree of pile head fixity. If the cap provides perfect restraint against rotation, deflections are only about...

A History of Environmental Engineering in the United States
Environmental engineering is a relatively new name for a type of engineering that began in the United States in the 1830s. Under different names, it continued to evolve to satisfy environmental...

Structural Expression in Wind Sensitive Structures
Architectural details can impact both the local cladding pressures on a structure as well as the overall structural response. Figure 1 shows a pair of roof corner vortices on the upper...

Power Shift
Engineers designing a Manhattan skyscraper with offices in the lower floors and residences in the upper found that they had to employ several unusual methods to accommodate client needs....

Pressure Relief
When the two basins making up a 90 acre reservoir in New York needed to be emptied and cleaned, engineers decided to use the 2,750 ft (840 m) long concrete wall dividing them as a dam....

Lesssons Learned from Experience Dealing with Risks of Extreme Events: Part II
For every known IS vulnerability, there is a matching countermeasure. However, we do not know all IS vulnerabilities. The following tasks are geared towards identifying IS vulnerabilities,...

A Paradigm Shift in Irrigation Management
In coming decades, irrigated agriculture will be called upon to produce up to two thirds of the increased food supply needed by an expanding world population. But the increasing dependence...

Leakage Control—Finding a New Resource from the Existing One
It is estimated that by the year 2005, one person in two will have an insufficient supply of one of the world's most precious elements: water. Worse still, it is predicted that this shortage...

Guidelines for Testing Large Seismic Isolator and Energy Dissipation Devices
This report outlines the HITEC Technical Evaluation Plan for large seismic isolator and energy dissipation devices. The plan is designed to characterize the fundamental properties and...

Control of Microorganisms in Drinking Water
Prepared by the Water Supply Engineering Technical Committee of the Infrastructure Council of the Environmental and Water Resources Institute of ASCE. ...

Deep Freeze
In engineering, overcoming a failure can sometimes be more instructive than completing a project with unqualified success. Such was the case with the collapse and repair of a force main...

Comparison of Hydrodynamic Parameters for a Floating Breakwater
The U. S. Army Engineer Research and Development Center is in the process of developing a Rapidly Installed Breakwater System (RIBS) for use in Joint Logistics Over the Shore Operations...

Quality Control Test for Prestressing Wires in Concrete Pressure Pipe
Prestressed concrete cylinder pipe (PCCP) was introduced in 1942 as a high pressure capacity conduit for water transmission. The principal element of the design and construction that imparts...
