Model Performance of Water-Current Meters Model Performance of Water-Current Meters
The measurement of discharge in natural streams requires hydrographers to use accurate water-current meters that have consistent performance among meters of the same model. This paper presents the results of an investigation into the performance of four models of current meters - Price type-AA, Price pygmy, Marsh McBirney 2000 and Swoffer 2100. Tests for consistency and accuracy for six...

Near-real-time simulation and internet-based delivery of forecast-flood inundation maps using two-dimensional hydraulic modeling--A pilot study for the Snoqualmie River, Washington Near-real-time simulation and internet-based delivery of forecast-flood inundation maps using two-dimensional hydraulic modeling--A pilot study for the Snoqualmie River, Washington
A system of numerical hydraulic modeling, geographic information system processing, and Internet map serving, supported by new data sources and application automation, was developed that generates inundation maps for forecast floods in near real time and makes them available through the Internet. Forecasts for flooding are generated by the National Weather Service (NWS) River Forecast...

Review of selected features of the natural system model, and suggestions for applications in South Florida Review of selected features of the natural system model, and suggestions for applications in South Florida
A study was conducted to review selected features of the Natural System Model, version 4.3 . The Natural System Model is a regional-scale model that uses recent climatic data and estimates of historic vegetation and topography to simulate pre-canal-drainage hydrologic response in south Florida. Equations used to represent the hydrologic system and the numerical solution of these...

Review and evaluation of a model for simulating the natural hydrology of South Florida Review and evaluation of a model for simulating the natural hydrology of South Florida
The South Florida Ecosystem Program is an intergovernmental effort to re-establish and maintain the ecosystem of South Florida. One element of the restoration effort is the development of a firm scientific basis for making management decisions. The U.S. Geologcal Survey (USGS) is one of the agencies that provides this needed scientific information through the USGS South Florida Ecosystem...

Effects of pulsating flow on current meter performance Effects of pulsating flow on current meter performance
Summarized are laboratory tests for current meter response to pulsating flows. Included are results for mechanical and electromagnetic water-current meters that are commonly used for stream gaging. Most of the vertical-axis and horizontal-axis types of mechanical meters that were tested significantly underregistered the mean flow velocity when the magnitude of the pulsating portion of...
