LiDAR Differencing Reveals How Subsidence Is Tied to Basin Structure in Cedar and Parowan Valleys, Utah
Topographic differencing using high-resolution elevation data is a powerful tool for investigating land surface change. Impacts from ground subsidence were first observed in southern Utah in 2005 after winter flooding eroded earth fissures near Beryl Junction. In 2009, ground cracks were discovered throughout a new d...
