Riverine Flow Observations and Modeling: Sensitivity of Delft3D River Model to Bathymetric Variability
Abstract
The goal of our effort is to understand river and inlet fluid dynamics through in situ field observations and model validation. The primary objects are to: 1) establish the river flow response to horizontal (e.g., river width variations, bends, groins, etc.) and vertical bathymetric variability (e.g., channels and shoals, bars and dunes) with GPS-equipped surface drifters, dye sensors, an Unmanned Surface Vehicle (USV), and an Unmanned Underwater Vehicle (UUV) in varying river reaches that are charateristically different; and 2) validate Delft3D river flow model with these unique observations and subsequently examine the sensitivity of Delft3D river flow model to bathymetric variability in general under a wide range of forcing conditions using an ensemble approach.
