Impact of Different Types of Coastal Defenses on Overtopping and Flooding

Demonstration in a 2D physical model (wave tank) of how different types of coastal defenses affect wave overtopping and flood risk. This video compares the performance of vertical and curved seawalls, stepped and sloped revetments, rock armor, and submerged breakwaters.

Impact of Different Structures on Flow in Rivers and Channels

Physical model demonstration of the effect of different engineering structures such as weirs, bridges, culverts, and debris filters on flow in rivers and channels.

Beach: A River of Sand

Video explaining how sandy beaches are formed and how they are affected by nature and man-made structures.

Turbulence

Explanation of turbulence, the characteristics of turbulent (and laminar) flows, and their importance in mixing processes, presented by The National Committee for Fluid Mechanics Films.

What Level is Sea Level? - What is Sea Level and How is it Determined?

A discussion about sea level, what it is and how it is determined, considering the constant changes due to waves and tides.

Rotational and Irrotational Flows

Explanation of the behavior of rotational and irrotational flows from the International Association for Hydro-Environment Engineering and Research (IAHR).

Flow Visualization

Experimental methods for flow visualization and characterization, presented by The National Committee for Fluid Mechanics Films.

Ocean Currents

Video explaining ocean currents, their circulation, and their effects on climate.

Wave Physics

Explanation of wave formation and the propagation and transformation processes that affect them.

Rivers: The Geological Work of Surface Runoff

Video illustrating the relationship of rivers and other forms of surface runoff with sediment transport, hydraulic erosion, and the geomorphological changes they can cause.
