Request: information on drought effects (e.g., cracks) in levees

Dear all,

During last month’s EURCOLD Symposium I presented a paper on drought effects on levees; see https://www.researchgate.net/publication/336641742_Mitigating_drought_risk_for_levees_Mitigating_drought_risk_for_levees . For the Sept2020 Floodrisk Symposium, I wish to extend this work and include some more experiences regarding drought effects on levees. However, it turned out to be quite hard to find publications and data (such as drought crack dimensions+position and other properties, drought crack development and recovery, best practices on remedial measures, etc.). Who can help me out, and send me some useful weblinks/publications and/or [summarized] data?

Thanks in advance!

Marcel Bottema
