Scour maps in single span-arch experiments with and without log debris . Flow is from right to left.

Followings are a few photos showing our recent activities in flume experiments (flow is from right to left).Lab photos

Following photo illustrates pressure sensors embedded in a pier model for measuring hydrodynamic pressure (acoustic Doppler velocimeter (ADV) can be also seen on the left side).
