Field observations provide valuable data regarding the nearshore tsunami impact, yet only in inundation areas where tsunami waves have already flooded. Therefore, tsunami modeling is essential in order to understand tsunami behavior and prepare for tsunami inundation. Analytical and numerical methods are widely applied to predict tsunami motion and...

The Great Lakes, Lakes Superior, Michigan, Huron, Erie and Ontario, are a system of interconnected freshwater lakes located primarily in the upper region of North America and on the Canada–United States border. Lake Michigan, the second largest in volume and the third-largest in surface area among the Great Lakes, is approximately 494 km long and 1...

Field observations provide valuable data regarding nearshore tsunami impact, yet only in inundation areas where tsunami waves have already flooded. Therefore, tsunami modeling is essential to understand tsunami behavior and prepare for tsunami inundation. It is necessary that all numerical models used in tsunami emergency planning be subject to ben...

Lake Ontario, the smallest in surface area among the Great Lakes, is the last lake in the Great Lakes’ hydrologic chain. In this study, Lake Ontario’s marine renewable energy resources are characterized. The historical wave records reveal up to 8m significant wave heights in Lake Ontario’s eastern basin. Furthermore, the lake’s historical water lev...

Bottom friction is an important parameter in tsunami inundation and should be included in the numerical simulations in order to reach reliable results. This study shows that smaller friction leads to larger runup values in the simulations and the runup distance of large amplitude waves is more friction sensitive. The analyses are conducted using FL...

Lake Erie has the fourth largest surface area, shallowest water depth and smallest volume among the five Great Lakes in North America. In this study the potential effects of climate change on the trends of extreme coastal events in Lake Erie are studied and beach responses to such effects are evaluated. Historically, the surface of Lake Erie was n...

Tsunamis in shallow water zones lead to sea water level rise and fall, strong currents, forces (drag, impact, uplift, etc.), morphological changes (erosion, deposition), dynamic water pressure, as well as resonant oscillations. As a result, ground materials under the tsunami motion move and scour/erosion/deposition patterns can be observed in the r...

In inundation zones, tsunami motion turns from wave motion to flow of water. Modelling of this phenomenon is a complex problem since there are many parameters affecting the tsunami flow. In this respect, the performance of numerical codes that analyze tsunami inundation patterns becomes important. The computation of water surface elevation is not s...

The movement of sea bottom or ground sediment material by tsunami cause erosion, deposition and hence bathymetry and topogrphy changes. The unexpected depth decrease at some parts of the enclosed basins and harbors may result in lack of movements of vessels. In order to understand the sediment movement inside the enclosed basins, Haydarpasa port in...

In order to stabilize the location of a jump and shorten the length of a stilling basin, appurtenances such as baffle blocks and sills are commonly used. However, corrugations, strip or staggered roughness elements, or gravels which cover the entire length of the basin may be an alternative. The results showed that corrugations, gravels and both st...
