Going Against the Grain
Conventional wisdom has it that granular soils perform better in mechanically stabilized earth (MSE) wall systems. Their properties are well known and simple to express in mathematical...

Coming to the Surface
In the past few years, the coastal areas of the Gulf of Mexico and much of Texas have experienced less than normal rainfall and record water demands. During this period, average daily...

Raising the Bar of BART
Although it was originally designed to withstand a strong earthquake, and did so admirably in 1989, the Bay Area Transit (BART) system was recently evaluated to determine its ability to...

National Water Quality Assessment: Moving from Measurement to Understanding
The USGS National Water Quality Assessment (NAWQA) program began in 1991. The objectives of the program were to characterize the quality of the Nations ground and surface water, assess...

Behaviour of Early-Age Shotcrete

Early Strength and Physical Properties in Accelerated Shotcrete

Mechanical Properties of Early Age Steel Fibre Reinforced Shotcrete

Making the Most of HPC
Developing high-performance concrete (HPC) was only the first step toward bringing a material with improved durability, strength, constructability, and mechanical properties to the bridge...

A Comparison of Two Three-Dimensional Shallow-Water Models Using Sigma-Coordinates and z-Coordinates in the Vertical Direction

Three-Dimensional, Hydrostatic and Non-Hydrostatic Modeling of Seiching in a Rectangular Basin

A Three-Dimensional Non-Hydrostatic Model for Free Surface Flows: Development, Verification and Limitations

Monotonicity Preserving Model for Free-Surface Flow with Sharp Density Fronts

Natural Tracers of Coastal Sediments
The properties of natural sediments can be used to determine their sources and to trace their transport paths through coastal environments. These properties include the mineralogies of...

Safeguarding Los Alamos
A forest fire that burned 48,000 ac (19,500 ha) around the Los Alamos National Laboratory, in New Mexico, in May 2000, created another problem for one of the nation's most...

Surface Irrigation
Surface irrigation refers to a large group of irrigation methods in which water is distributed by gravity over the surface of the field. Water is typically introduced at the high point...
