A couple of weeks ago we had a look at three different floods around the world, including Lima, Peru. However, the flooding in Peru was very extensive, so today we are looking at some other locations around Peru.
Here is a ‘before and after’ showing how the Moche River, which passes through Trujillo, Peru, created a new delta:

Further north we can see how the Chancay River grew significantly wider:

Zooming out and using Landsat imagery, we can see some large areas that were completely flooded. They are naturally swampy areas, but we could not find this extent of flooding in older imagery, so we believe it to be quite unusual.

The inland parts of Peru drain into the Amazon basin. There was also significant flooding there, but it is rain forest, so it is unlikely that we will see any high resolution satellite imagery (too much cloud cover). It also seems probable that as the water flows towards the ocean we will see floods along the Amazon in Brazil later in the year.
