RISEnsemble-Based Data Assimilation for Estimation of River Depths
Publisher: American Meteorological Society
Abstract: method is presented for estimating bathymetry in a river, based on observations of depth-averaged velocity during steady flow. The estimator minimizes a cost function that combines known information in the form of a prior ...
Predicting Large Ocean Wave Events Characterized by Bimodal Energy Spectra in the Presence of a Low-Level Southerly Wind Feature
Publisher: American Meteorological Society
Abstract: AbstractThree large wave events are simulated with WaveWatch III using different wind inputs and physics packages. The modeled output, including spectral shape and bulk parameter time series, are compared with National ...
An Inner-Shelf Wave Forecasting System for the U.S. Pacific Northwest
Publisher: American Meteorological Society
Abstract: n operational inner-shelf wave forecasting system was implemented for the Oregon and southwest Washington coast in the U.S. Pacific Northwest (PNW). High-resolution wave forecasts are useful for navigational planning, ...
Bathymetry Estimation Using Drifter-Based Velocity Measurements on the Kootenai River, Idaho
Publisher: American Meteorological Society
Abstract: elocity measurements from drifter GPS records are used in an ensemble-based data assimilation technique to extract the river bathymetry. The method is tested on a deep meandering reach and a shallow braided reach of the ...
Microelectrode Velocity Effects and Aquatic Eddy Covariance Measurements under Waves
Publisher: American Meteorological Society
Abstract: nterest in validating the eddy covariance (EC) technique under wave-induced flows led to a series of experiments in a 104-m-long large wave flume (LWF) using an acoustic Doppler velocimeter (ADV) and two oxygen microelectrodes ...
