“…The work of Cheng et al . [], through a systematic study of the individual processes controlling NTRs, corroborates that streamflow has a noticeable effect on water levels throughout the bay. However, even for extreme discharge events (the 2007 storm studied in that paper produced approximately a 20 year flow), the effect is secondary compared to that of offshore wave breaking.…”

“…These results are due primarily to the presence of large waves offshore in the winter season. These waves are unable to penetrate very far into Tillamook Bay [ Cheng et al ., ] resulting in an ocean‐to‐bay gradient in the differences between winter and summer CDFs. Figure c shows the conditions in the jettied inlet, where some wave penetration is found.…”

“…Cheng et al . [] recently completed a study of extreme storms in Tillamook Bay and one of the major findings was that offshore waves are the primary driver of nontidal residuals (NTRs) in the Bay. Radiation stress gradients setup by the breaking of large (10 m) offshore waves can lead to NTRs between 1 and 2 m in Tillamook Bay and other PNW estuaries.…”

“…The work of Cheng et al . [] essentially prioritizes processes in estuaries and this information should be used to investigate the feasibility of a reduced modeling effort. The complete time series results of the present study can act as the baseline by which a reduced modeling effort's success can be measured.…”

Climate change impacts on wave and surge processes in a Pacific Northwest (USA) estuary

Total water levels (TWLs) within estuaries are influenced by tides, wind, offshore waves, and streamflow, all of which are uniquely affected by climate change. The magnitude of TWL associated with various return periods is relevant to understanding how the hydrodynamics of a bay or estuary may evolve under distinct climate scenarios. A methodology for assessing the hydrodynamic response of a small estuary under major boundary condition perturbations is presented in this study. The coupled Advanced Circulation (ADCIRC) and Simulating Waves Nearshore (SWAN) model was used to simulate wave and water elevation conditions within Tillamook Bay, OR, USA for two long-term scenarios; 1979-1998 and 2041-2060. The model output provided multidecadal time series of TWLs for statistical analysis. Regional climate data from the North American Regional Climate Change Assessment Program (NARCCAP) were used to drive streamflow modeling (MicroMet/SnowModel/HydroFlow) and meteorological forcing within ADCIRC-SWAN. WAVEWATCH III, which was forced with global climate data from the Community Climate Science Model (CCSM, a contributing model to NARCCAP), was used to produce open boundary wave forcing. Latitudinal and seasonal gradients were found in TWLs associated with varying return periods for both the hindcast and forecast. Changes in TWLs from hindcast to forecast included the sea level rise component and were also modulated by changes in boundary conditions.

“…Locally-generated wind waves and propagating swell waves, generated by an offshore storm, which coincide with an extreme water level can increase flood hazard at the coast (Wolf 2009;Pye and Blott 2010). Maximum wave height at time of tidal high water can be significant for coastal flooding (Fairley et al 2014), and runup associated with direct wind setup or breaking offshore waves can influence defence overtopping and breaching (Cheng et al 2015). Future work to consider the influence of swell and wind waves on water levels and uncertainty in wave forcing has the potential to provide improved understanding of the combined effect of tide-surge-river-waves on water levels in a hypertidal estuary.…”

Astronomical high tides and meteorological storm surges present a combined flood hazard to communities and infrastructure. There is a need to incorporate the impact of tide-surge interaction and the spatial and temporal variability of the combined flood hazard in flood risk assessments, especially in hyper-tidal estuaries where the consequences of tide and storm surge concurrence can be catastrophic. Delft3D-FLOW is used to assess up-estuary variability in extreme water levels for a range of historical events of different severity within the Severn Estuary, southwest England as an example. The influence of the following on flood hazard is investigated: (i) event severity, (ii) timing of the peak of a storm surge relative to tidal high water and (iii) the temporal distribution of the storm surge component (here in termed the surge skewness). Results show when modelling a local area event severity is most important control on flood hazard. Tide-surge concurrence increases flood hazard throughout the estuary. Positive surge skewness can result in a greater variability of extreme water levels and residual surge component, the effects of which are magnified up-estuary by estuarine geometry to exacerbate flood hazard. The concepts and methodology shown here can be applied to other estuaries worldwide.
