Exploring Localized Mixing Dynamics during Wet Weather in a Tidal Fresh Water System
Abstract
:1. Introduction
2. Methods
2.1. Study Area
2.2. 1997 CSO Mixing Zone Study
2.3. Model Setup
- (i)
- tidal only: forcing with predicted water level at the open boundary, no wind field;
- (ii)
- no wind: forcing with observed water level at the open boundary, no wind field;
- (iii)
- wind: forcing with observed water level at the open boundary and wind field inside the model domain.
