Despite having the container parked in Egmond we were able to measure some aeolian transport Yesterday. Using the quad and cart, the SalDec system and sonic anemometers were transported to the field location. As we are getting some routine in setting up the equipment the sonic anemometers and first SalDec system were quickly deployed. The strong Northwesterly wind (~15m/s) resulted in almost constant shore parallel transport near the dunefoot. Halfway on the upper beach were we had set-up our SalDec system the transport was a bit gustier and more in line with the general NW wind direction. The surge caused by the strong NW winds caused water levels during low water to be still half a meter above mean sea level, resulting in a very narrow beach. We decided to placed no additional devices further shoreward on the beach as they could be to close to the sea.
Yvonne 'Doctor Bodemvocht' Smit honored us with a field visit. She discussed the sampling strategy with one of the MSc students (Jorn Tuinman) who is studing the spatial and temproral variations in surface moisture. Yvonne also made some nice pictures of the instruments and us working in the field (see below).
This was also the first time we were able to place sand catchers on the foredune. Sand catchers are used to quantify aeolian transport at a given location. By placing multiple sand catchers along a cross-shore transect we can see how transport varies over the beach and foredune. Sand catchers can only work in dry conditions as moisture causes the tubes of the sand catchers to become clogged. Unfortunately, some short periods of rain spoiled our measurements for the day. On the bright side we gained some experience installing them.
Due to the high surge we had a short working window and as the water came rushing in we had to remove our instruments rapidly and transport everything back to Egmond.
