Design of an In-Situ Directional Wave Gage for One Year Deployments
This paper describes the design and implementation of a new in-situ, directional wave gage that records hourly directional spectra continuously during a 13-month deployment period. If...

Design and Testing of the NDBC Wave Processing Module
The U.S National Data Buoy Center (NDBC) has developed a new wave data acquisition and processing system, called the Wave Processing Module (WPM), using state-of-the-art technologies and...

A Method for Locating Spikes in a Measured Time Series
Raw directional wave sample time series are frequently contaminated with spikes from various sources. The standard procedure in correctly editing these time series includes locating and...

The Development of a Wave Data Analysis Standard for a National Wave Measurement Program
The Field Wave Gaging Program (FWGP) at the U.S. Army Corps of Engineers' Coastal Engineering Research Center (CERC) collects and analyzes wave data from around the U.S. coastline to contribute...

Evolutionary Fourier Analysis of Wave Data
A new method is presented for analyzing nonstationary water level height time series. The usual assumption of pseudo-stationary intervals is avoided and the wave spectra can be changing...

A New Correction Procedure for Shipborne Wave Recorder Data
A new correction procedure for Shipborne Wave Recorder (SBWR) wave height and spectral data is described. The method is based on a reassessment of the available frequency response measurements...

Extensive Comparison of Directional Wave Analysis Methods From Gauge Array Data
In order to settle an efficient operational wave gauge array for estimating directional wave spectrum, several directional analysis methods are implemented and compared. These methods...

Case Studies of Extreme Wave Analysis: A Comparative Analysis
Several methods of extremal wave analysis have been applied to two sets of deep water extreme wave data. One set consisted of three-hourly sea-state records collected during a nine year...

Operational Interactive Hydrologic Forecasting with the National Weather Service River Forecast System
The National Weather Service River Forecast System (NWSRFS) consists of several major hydrometeorologic subcomponents to model the physics of the flow of water through the hydrologic cycle....

BPA Realtime Hydrologic Forecasting System for the Columbia River Basin
Bonneville Power Administration (BPA) markets and distributes the hydroelectric power produced at 30 federal projects in the Columbia River Basin. In order to plan the System's coordinated...

The Effects of Spatial Resolution in Modeling the North Fork Drainage of the Gunnison River Basin
The U.S. Geological Survey Precipitation-Runoff Modeling System (PRMS) is a modular, distributed-parameter, watershed modeling system developed for use in evaluating the effects of climate...

Elmhurst Quarry Flood Control Project
Conversion of a limestone quarry into an off-line reservoir provides flood protection for a rapidly developing County in the suburbs of Chicago....

Using GIS to Develop 2-D Hydraulic Models
As communities along rivers and streams continue to develop, the demand for more accurate floodplain analysis and flood warning will also increase. Computer systems continue to develop...

Probabilistic Characterization of Droughts
The Palmer Drought Severity Index (PDSI) uses a set of meteorologic and hydrologic variables to create a numerical value for drought severity. The index values are grouped into drought...

Instream Flow Policy: An Alternative to Minimum Flowby
The limitations of current instream flow policies based on the concept of minimum flowby are discussed. An alternative policy based on sharing the available resource among competing uses...

Colorado River Decision Support System
Colorado is developing its own tools, such as the Colorado River Decision Support System (CRDSS), to evaluate alternative strategies and establish an informed and factual position regarding...

Arizona Groundwater Management Alternatives
Sustainable groundwater management policies are examined through the use of a hydrologic-economic impact model of Arizona surface and groundwater use. Present water use practices were...

Explicit Stochastic Modelling of a Reservoir for Hydropower Production
A new reliability model for planning the operation of a multipurpose reservoir for hydropower generation and flood control, which considers the stochastic nature of inflows and power demand...

Simulating Hourly Hydropower Operations for the Assessment of Environmental and Economic Impact
Generation of peaking power at Glen Canyon Dam causes river flow and stage to fluctuate on an hourly basis. This has been shown to impact the downstream physical and biological environment....

Hydrodiplomacy on Forester Creek
The goal of this paper is to share information regarding political battles confronting the engineer with regards to drainage issues and concerns. Very often drainage boundaries do not...
