Mooring the PT

The first action of the 2D fieldwork was mooring a PT (Pressure Transducer) offshore the study site at about -14 m, below the closing depth of the beach profile (around -12 m in this area).

The mooring structure is a car tire filled with concrete and metal  bars,  with a stainless steel structure on top to attach the PT.

The PT was deployed by two divers (Zapa and Inês), on September 13, at a depth during diving of 16 m.

Daniel is passing the PT to Zapa. Inês is behind the boat in this photo.

The skipper was Daniel and the RUSH team was Ana and André, who did the location of the equipment with the GPS.

Plans for the first 2D fieldwork

The first 2D fieldwork is planned for September, 15th and 16th.
The equinoctial spring tide will (hopefully) provide some extra centimeters to the water level which may be enough to overwash the barrier.

What we are asking Poseidon is to provide us the oceanogaphic conditions to keep the area to the right (photo below) wet, with the instruments measuring overwash flow; and the area to the left dry with the base station, tents, computers, ...

Small elevation in the backbarrier , suppose to be 'safe', where the base station will be set.

Top of the barrier, where instruments will be deployed.

First 3D survey

When we arrived at the beach the full moon was still up. Beautiful sunrise in the Ria Formosa.

The survey started at 06:30 and ended at 11:30. We did 24 cross-shore profiles, and 1800 m of a maximum runup alongshore profile.

The beach had a fair-weather profile, occasionally with more than 2 berms. 

Nevertheless, further east some small overwash intrusions were detected.

We are now ready for overwash.

Let the games begin......

Fieldwork plan

RUSH project intensive fieldwork is about to start.
Our first attempt to measure overwash will be on the 16th and 17th September (Sunday and Monday).
During fieldwork we will deploy equipment (ADP, 2 EMC, ADV, 8 PTs, and video) in 8 stations from the low tide beach level until the backbarrier.

This is one of the field sites, close to Ancão Inlet.

This is the urban study site, at Praia de Faro.

Fieldwork preparation

It has been 3 long weeks preparing equipment and mooring structures. So far so good, almost done!!
Video is behind schedule but we do our best to have everything ready on time.
Take a look at the high-tech device we done 2 days ago.

Welcome

Welcome to RUSH project!
This is a scientific project devoted to the study of overwash processes.
Hopefully during the next 3 years you will read about our fieldwork, results, and findings.
