Higher Ground
Thirty floods over the course of a century, capped by three major floods in 1993, finally convinced residents of Pattonsburg, Mo., that it was time to move the entire town to higher ground....
Dam Engineers Go Over the Top
In the 1980s, dam engineers with the Lower Colorado River Authority worried that the Wirtz Dam, near Austin, Texas, would fail in the event of a maximum probable flood. They looked to...
Risk Management at Wahleach Dam
In a first-of-its-kind application, engineers used risk analysis to make event-driven design decisions to evaluate dam safety improvements at Canada's Wahleach Dam in British...
Flood-Runoff Analysis
This manual describes methods for evaluating flood-runoff characteristics of watersheds. Guidance is provided in selecting and applying such methods to support the various investigations...
Fran-Spotting
When Hurricane Fran slammed into the North Carolina coast last September, it ravaged a fragile barrier island system already torn up by Hurricane Bertha two months before. The result was...
Channel Stability Assessment for Flood Control Projects
This manual provides assistance for determining potential channel instability and sedimentation effects in flood control projects. It is intended to facilitate consideration of the type...
Aesthetics in the Constructed Environment

A New Look at Old Man River
After the 1993 Midwest flood, a research team conducted one of the largest aerial mapping projects in U.S. history�a year-long, $3.7 million effort that demonstrates the utility of photogrammetry...
Assessing Opal's Impact
Geographic information systems and other high-technology tools were used to quantify the effects of Hurricane Opal in October 1995. The Federal Emergency Management Agency, along with...
Water Wisdom of the Ancients
Two water systems thousands of years old--the falaj system in Oman and China's Dujiangyan water works--are still in use today. A climatologist describes how these systems...
Evaluation of Sampling Properties of General Extreme Value (GEV) Distribution-L-Moments Vs Conventional Moments
The sample estimates of conventional moments are shown to be biased and this bias increases for small samples, and especially so when the skewness is high (Wallis et al., 1974). The recently...
An Extended Relaxation Technique for Unsteady Flows in Networks
A recent enhancement to the FLD WAY model is the addition of an extended relaxation technique for modeling unsteady flows in a dendritic (tree-type) network of channels with tributaries...
Two-dimensional Sheetflow Modeling for Wetland Restoration
The hydrologic-hydraulic behavior of wetlands and transitional upland-wetland areas on coastal flat terrains in the Cocohatchee Canal Watershed in Collier County, Florida was simulated...
Siting of Grade Control Structures
In siting a grade control structure in a stream, hydraulic considerations must be integrated with other important siting factors. A review of several of the important siting factors is...
Statistical Distributions and Natural Hydrograph
For design projects in the water resources area, a hydrograph is commonly used to determine the flood volume generated by a given drainage basin. The division of total flow into direct...
FLODRO 2.0: A User Friendly Personal Computer Package for Flood and Drought Frequency Analyses
The use of personal computers have changed dramatically the way to perform several studies related with hydrological problems. The increased capabilities of the current generation of personal...
An LPI Numerical Implicit Solution for Unsteady Mixed-Flow Simulation
A Local Partial Inertia (LPI) technique is developed as an option within the National Weather Service (NWS) FLDWAV dynamic flood routing model to enhance its capability to model unsteady...
Hydraulic Performance of Open Channel Breaching
Flood flow in natural channels with floodplains is often confined in the main channel by the presence of levees. The hydraulic performance of these kinds of channels can be seriously affected...
Santa Clara River Fluvial Analysis
The Santa Clara River watershed, located in Los Angeles County, has been subject to rapid increases in population and urban development, resulting in channelization, new bridges, and increased...
Habitat Preservation and Enhancement Associated with San Diego Creek Flood Control Channel Improvement
San Diego Creek, an important regional flood control channel in southern Orange County, California, flows 2.4 kilometers through the mixed-use areas of Irvine Center (San Diego Freeway...
