New Techniques and Data Sources for PMP
Testing has been conducted on new methods and storm data sources for the past two years with the purpose of providing more tools to dam owners for the assessment of probable maximum precipitation...
Colorado River Probable Maximum Floods
Upper limit design rainstorms (ULDRS) were developed for three locations in the Colorado River drainage above Hoover Dam. For each location, the rainfall magnitudes, spatial and temporal...
Tidal Flooding Analysis, San Francisco Bay
Many leveed areas adjacent to San Francisco Bay are potentially subject to tidal flooding. In response to this concern, Congress authorized the U.S. Army Corps of Engineers to conduct...
Winds, and Their Effects on Tides, in San Francisco Bay
Many leveed areas adjacent to San Francisco Bay are potentially subject to tidal flooding. In response to this concern, Congress authorized the U.S. Army Corps of Engineers to conduct...
New Lessons About the Hydraulic Performance of Highway Storm Sewer Inlets
Laboratory experiments were performed with highway storm water curb inlets to 1) reduce the oblique standing wave that extends into the highway from the downstream side of the inlet and...
Model Study of a Hurricane Surge Barrier Gate Valve
Physical model studies were conducted to determine the hydraulic performance of a unique vertical butterfly-gated structure. These studies were also used to determine the torque on the...
Conventional Storm Drainage Which Recharges the Groundwater
Since the demand for water is on the rise, more resourceful means of retaining and controlling the release of stormwater is needed. This retained stormwater may then be used for aesthetic...
Rainfall-Runoff Modeling in a Small Urban Watershed
Knights Branch watershed is located in Dallas, Texas, and it covers an area of about 5 mi2 (13 km2). Due to...
Hurricane Hugo One Year Later
Hurricane Hugo, which made landfall on September 21, 1989, was the first serious storm to cross the South Carolina coast in over 30 years. During this period, the coastal areas had grown...
Joint Occurrence of High Tide and Storm Surge in California
High tides or high storm surges separately generally do not pose a hazard for flooding or structural damage in California. However, when storms and periods of high tides coincide, the...
The Concept of the New Waterway Storm Surge Barrier: Reliability as an Integral Part of a Nation's Sea Water Defense System
In the southwest of the Netherlands a storm surge barrier is to be built in the waterway that gives access to the port of Rotterdam. Strict design conditions ensure that only very slight...
Probable Maximum Floods at the Yucca Mountain Exploratory Shafts
This paper presents an analysis of flood flows in the Coyote Wash at the proposed high level nuclear waste repository site at Yucca Mountain, Nevada. Estimates of the hydrographs at various...
Utilization of Stormwater Runoff to Recharge Underlying Aquifer
Based on the available data and its proximity to the Capital area, Wadi Al Khawd was selected as the site of the first aquifer recharge project in Oman. The project was designed by Stanley...
Site Specific Hydrological Model for Permaculture Application
This paper presents results of a study conducted on a small pond and watershed in Waterbury, Connecticut. The Soil Conservation Service method presented in Technical Release #55 (TR 55),...
Curvilinear Long Wave Hydrodynamic (CLHYD) for Tidal Circulation and Storm Surge Propagation
The objective of this paper is to demonstrate the ability of a two-dimensional long wave hydrodynamic model to simulate long wave processes in curvilinear coordinates. The series of tests...
Characteristics of Flood-Producing Rainstorms in the Midwest
At the Midwestern Climate Center, a comprehensive re-evaluation and updating of heavy rainstorm frequency relations for 9 Midwestern states is in progress. A special effort is being made...
Asymptotic Determination of Curve Numbers from Rainfall?Runoff Data
Background, general instructions, and examples are given for determining Runoff Curve Numbers (CN) from small watershed event rainfall and direct runoff data sets. In order to preserve...
Evolution of Drainage Criteria, Albuquerque, New Mexico
Storm drainage in Albuquerque, NM is a central issue in land development. To expedite municipal development while assuring public safety and preserving environmental attributes in a public...
A Multi-Level Contour Method for Tracking and Forecasting Rain Fields of Severe Storms by Weather Radars
A new automated method is developed in order to track and predict in short-term (15 min-1 hr lead times) the evolution of rain fields in time and space, as observed by weather radars....
Simulating Spatially Varied Thunderstorm Rainfall
Using data from two independent, relatively dense networks of raingages located in the vicinity of Tucson, Arizona, the spatial distribution of thunderstorm rainfall was determined as...
