Dijkinspecties vanuit de ruimte: droom of werkelijkheid?

We hebben in Nederland ongeveer 20.000 km waterkeringen en het is kostbaar en tijdrovend om deze regelmatig fysiek te inspecteren. Met radarsatellieten wordt deformatie op meer plekken, vaker, en nauwkeuriger gemeten. Hierdoor kan het gedrag van keringen continu worden gemonitord en kan afwijkend gedrag vroegtijdig worden gedetecteerd. Deze...

Sub-seasonal Levee Deformation Observed Using Satellite Radar Interferometry to Enhance Flood Protection

Levees are critical in providing protection against catastrophic flood events, and thus require continuous monitoring. Current levee inspection methods rely on limited information obtained by visual inspection, resulting in infrequent, localized, mostly qualitative and subjective assessments. This hampers the timely detection of problematic...

Applicability of satellite radar imaging to monitor the conditions of levees

Levees are critical systems in safeguarding an area against catastrophic flooding events with potential fatalities and economic losses. Current monitoring methods of levees highly rely on expert judgement, resulting in infrequent and subjective assessments of their status. Satellite radar imaging, in particular using interferometry (InSAR),...
