Task committee on experimental uncertainty and measurement errors in hydraulic engineering: An update Task committee on experimental uncertainty and measurement errors in hydraulic engineering: An update
As part of their long range goals for disseminating information on measurement techniques, instrumentation, and experimentation in the field of hydraulics, the Technical Committee on Hydraulic Measurements and Experimentation formed the Task Committee on Experimental Uncertainty and Measurement Errors in Hydraulic Engineering in January 2003. The overall mission of this Task Committee is...

Radar stage uncertainty Radar stage uncertainty
The U.S. Geological Survey is investigating the performance of radars used for stage (or water-level) measurement. This paper presents a comparison of estimated uncertainties and data for radar water-level measurements with float, bubbler, and wire weight water-level measurements. The radar sensor was also temperature-tested in a laboratory. The uncertainty estimates indicate that radar

An intensity scale for riverine flooding An intensity scale for riverine flooding
Recent advances in the availability and accuracy of multi-dimensional flow models, the advent of precise elevation data for floodplains (LIDAR), and geographical GIS allow the creation of hazard maps that more correctly reflect the varying levels of flood-damage risk across a floodplain when inundatecby floodwaters. Using intensity scales for wind damages, an equivalent water-damage flow...

Computational technique and performance of Transient Inundation Model for Rivers--2 Dimensional (TRIM2RD) : a depth-averaged two-dimensional flow model Computational technique and performance of Transient Inundation Model for Rivers--2 Dimensional (TRIM2RD) : a depth-averaged two-dimensional flow model
A numerical computer model, Transient Inundation Model for Rivers -- 2 Dimensional (TrimR2D), that solves the two-dimensional depth-averaged flow equations is documented and discussed. The model uses a semi-implicit, semi-Lagrangian finite-difference method. It is a variant of the Trim model and has been used successfully in estuarine environments such as San Francisco Bay. The abilities...
