Communication Breakdown
Are modern telecommunications networks vulnerable to earthquakes? Researchers say yes, and have developed a computer tool to quantify potential economic impacts. Telecommunications service...
Shear-wall Retrofit
With the effects of the 1989 Loma Prieta earthquake still lingering and another quake looming sometime in the future, engineers faced with retrofitting the Pacific Gas & Electric...
Seismic Solutions for Steel Frame Buildings
After the Northridge Earthquake, damage in steel moment resisting frame connections stunned engineers. Now those engineers are scrambling to find and test new kinds of connections. This...
Spotlight on Steel Moment Frames
Engineers' confidence in moment connections was shattered when damage was discovered after the 1994 Northridge earthquake. Such connections are now a hot subject for U.S....
Distributed Parameter Hydrologic Modeling and NEXRAD for River Forecasting: Scale Issues Facing the National Weather Service
With the advent of NEXRAD (Next Generation RADar), the National Weather Service has the opportunity to move from current lumped parameter modeling to more of a distributed parameter hydrologic...
Dam Foundation Erosion Study: The Design of a Sidewall Orifice for Simulation of a Free Trajectory Overtopping Jet
This paper describes the design of a sidewall discharging orifice for simulation of a free trajectory overtopping jet. A sidewall orifice discharges through the sidewall of a pipe. The...
Flow through Vertical Barrier Screens?Numerical Model
A simple one-dimensional numerical model based on the energy equation is developed to predict the normal flow distribution through barrier screens composed of several vertical segments...
Sediment Removal from Stormwater Runoff
Sediment traps, also known as baffle boxes, are being used throughout the state of Florida to remove sediment from stomiwater. A baffle box is divided into three compartments by two bathers,...
Filling and Emptying System Model Study for the Innovative Lock Design
Funding constraints have generated innovative ideas regarding the hydraulic system of proposed navigation locks. Two fundamental questions addressed in the innovative lock design study...
Modeling of Rattlesnake Creek Watershed Using Swat Model
