Gijs Hendrickx, MSc.
Gijs is PhD candidate from Delft University of Technology visiting prof.dr. Ehab Meselhe (Tulane University). This collaboration investigates a sill as nature-based solution to mitigate salt intrusion, as implemented in the Lower Mississippi River. This study fits in the general scope of Gijs' PhD topic of developing nature-based solutions to mitigate salt intrusion.
Presentation Description
Designing a sill to mitigate salt intrusion: Lessons learned from the LMRDuring extreme drought conditions, a sill is placed in the LMR to halt the landward propagation of the salt wedge to prevent upstream contamination of water-intakes. This temporary solution raised the question whether this solution can be exported to other deltaic regions as well, how the sill mitigates further salt intrusion, and when it is most effective in doing so. Results show that the tide is an important factor in determining how the sill reduces the salt intrusion, and that salt overspill is not necessarily a bad thing.
