“…Supported by post-typhoon survey reports (Bricker et al, 2014;Tajima et al, 2014), recent wave models (Roeber and Bricker, 2015;Shimozono et al, 2015), eyewitness accounts, and video footage (Mas et al, 2015;Bricker and Roeber, 2015), our findings suggest that a variety of hydrodynamic processes related to TC landfall must be considered when interpreting boulder deposits along coasts. These processes may include, in addition to incident (potentially very high) gravity waves and (or on top of) pressure-and wind-driven storm surge, meteo-tsunamis or seiches (Mori et al, 2014), as well as infragravity waves with periods of up to several minutes.…”

“…Hence, it experienced maximum wind speeds with the highest modelpredicted waves of up to 19 m, but only a limited wind-driven surge during Haiyan (Bricker et al 2014). Field indicators document inundation levels of up to 6 m onshore flow depth, nearly 11 m run-ups above local event tide level, and inundation distances of up to 800 m depending on onshore topography (Quinto et al, 2014;Tajima et al 2014;Shimozono et al, 2015).…”

“…To explain the surprisingly high inundation levels in SE Samar (Tajima et al, 2014) and the bore-like coastal flooding captured at Hernani (Mas et al, 2015), Bricker et al (2014) hypothesized that infragravity waves (such as surf beat) (Munk, 1950) were caused by non-linear wave interactions with the reef, which are not resolved by the existing Delft3D and SWAN models. A Haiyan-related meteo-tsunami can be excluded due to a lack of bathymetric conditions with suitable resonance properties.…”

Abstract. Fields of dislodged boulders and blocks record catastrophic coastal flooding during strong storms or tsunamis and play a pivotal role in coastal hazard assessment. Along the rocky carbonate coast of Eastern Samar (Philippines) we documented longshore transport of a block of 180 t and boulders (up to 23.5 t) shifted upslope to elevations of up to 10 m above mean lower low water level during Supertyphoon Haiyan on 8 November 2013. Initiation-of-motion approaches indicate that boulder dislocation occurred with flow velocities of 8.9-9.6 m s −1 , which significantly exceeds depth-averaged flow velocities of a local coupled hydrodynamic and wave model (Delft3D) of the typhoon with a maximum < 1.5 m s −1 . These results, in combination with recently published phase-resolving wave models, support the hypothesis that infragravity waves induced by the typhoon were responsible for the remarkable flooding pattern in Eastern Samar, which are not resolved in phase-averaged storm surge models. Our findings show that tsunamis and hydrodynamic conditions induced by tropical cyclones may shift boulders of similar size and, therefore, demand a careful re-evaluation of storm-related transport where it, based on the boulder's sheer size, has previously been ascribed to tsunamis.

“…These studies have confirmed the reasonable hindcast skills of the model for reproducing peak surge heights along the Bangladesh coast. Apart from these, Tajima et al [29] employed the same model for Typhoon Haiyan at the Philippines and obtained good agreement between observed [30] and computed values of peak surge heights near San Pedro Bay during Typhoon Haiyan. Long-term tidal water level measurement data are scarce in the Meghna Estuary and at the Northern Bay of Bengal area.…”

Abstract:The impact of cyclone track features (e.g., cyclone translation speed, cyclone path and cyclone landfall crossing angle) in combination with tidal phase shift upon surge characteristics have been investigated at the Bay of Bengal along the Bangladesh coast. A two-dimensional hydrodynamic model in a horizontal direction (2DH) coupled with a storm-surge model has been employed for the study. Numerical experiments with three different cyclone translation speeds show that when the surge height is directly forced by the cyclonic wind speed especially within the RWM (Radius of Maximum Wind), faster translation speed produces reduced surge height as the cyclone gets less time to force the water. On the other hand, at locations outside the RMW, surge waves travel as a propagating long wave where higher surges are produced by faster moving cyclones. It is found that surge arrival times are more and more affected by tidal phase when cyclone translation speed is reduced. Analysis of seven hypothetical parallel cyclone paths show that local bathymetry and complex coastline configurations strongly influence the surge height and surge arrival time along the Bangladesh coast. From the analyses of cyclone landfall crossing angles at the Khulna and Chittagong coasts, it is observed that surge durations are the smallest at both the coasts when the coastline crossing angles are the smallest.

“…However, even in the present climate conditions, there were some typhoons which might be able to cause severe disasters if it had passed the worst course. Typhoon Haiyan, for example, caused severe storm surge disasters in the Philippines in November 2013 (Tajima et al 2014). In Japan, Typhoon 1216 (hereafter T1216) which passed on the western sea of the Kyushu Island in September 2012 was actually such a dangerous typhoon.…”

In this study, to understand the characteristics of storm surges along the coast of innermost area in the Ariake Sea, the tidal changes at three points along the embankments were measured for about three months in the summer of 2012. In addition, several storm surge simulations were conducted by using the parameters of an actual Typhoon No.16 (T1216) to investigate the possible large storm surge in the Ariake Sea under the present climate conditions. The observational results show that the storm surge amplifies remarkably in the innermost area in particular. Furthermore the numerical simulation results imply that there is the risk of serious storm surge disaster in the Ariake Sea under even the present climate condition.
