It is the Mosul Dam that is located in Iraq.

It's very huge.

It's 300 meters tall.

tall, has a height of 300 meters and three kilometers from one part to the other part of the dam.

So it contains a huge amount of water from the upper side, there is the water that contains and below there, there is the river that the water comes out from the reservoir that is on top.

Why the Mosul Dam?

The Mosul Dam has a problem.

It has been built on a bed of gesso, how you say?

And gepsum is, while it's in contact with water, it melts.

So the Mosul Dam is dangerous because it has a serious problem of stabilization.

In this case, there are a lot of what's called satellite methods and synthetic radar methods that are devoted to perform the so-called infrastructure monitoring.

And in this case, the Mosul Dam is crucial to be observed by radar.

In this case, I wanted to see the slide 37, please, here.

Inside the dam, look, there is a tunnel, the red line, the tunnel.

And here we have people that are working inside the tunnel.

And the task was, with my technique, is it possible to detect the tunnel?

We go in slide 38.

Okay, and we see on the right top, there is the tunnel.

Just to explain you, where you see red, the vibration energy is high, so it's red.

When you see blue, the vibration energy is low, and inside the tunnel, because you have the air, you don't have vibration, so it's low.
