SummaryThe city of Regina is built on montmorillonite clays with high swelling and slumping potential when subjected to changes in water input/output. Clay-swelling leads small-scale ground motion that damages buildings and infrustructure. The inhomogenous distribution of the clays and seasonal changes of water saturation lead to differential motion across buildings, which together with the complications from seasonal snowcover and microclimate call for PSI analysisof very high spatial and temporal resolution SAR data. We propose to conduct a yearlong study of ground motion in Regina using aTerrasAR high resolution spotlight stack.We willenhance ourPSI chain for this type of applications, allowing to separate the inSAR motion componentfrom spatially uncorrelated height error, urban microclimate, and phase/decorrelation effects from seaosnal snow cover and soil moisture
