Reeds enkele jaren staat er een opstelling in het Sedlab ter validatie van de valsnelheid van sediment in water. Deze opstelling werd voornamelijk gebruikt door studenten (18_148 en 24_003). Hierbij werd een algoritme/script opgemaakt in Streams (Open source Software) voor het verwerken van de opnames van het bezinkende sediment.
De geschiktheid van streams wordt ondertussen in twijfel getrokken door E&O. Met een snelle poging werd immers ondervonden dat OpenPIV sneller en ogenschijnlijk meer betrouwbare resultaten oplevert.
Gezien de interesse van WatSed om de valsnelheid van sediment accuraat te kunnen bepalen alsook de interesse van Kust ter voorbereiding van het Dunefront project (23_031) is het opportuun om validatie experimenten uit te voeren waarmee de betrouwbaarheid van verwerking met OpenPIV aangetoond kan worden.
