Constraining Spatial Variability in Erosion Rates

This study aims to constrain erosion rates by analyzing various factors including topography data (SRTM, ASTER, DTED, GTOPO30, LANDSAT), climate information (TRMM, Rain Gages, Stage Recorders), and Cosmogenic Isotopes measurements. It includes analysis of Fluvial Incision power and shear stress, discharge needs, river slope, channel width, power distribution, and antiformal uplift. The research also explores the relationship between Zircon Helium Age and stream power, with a focus on understanding erosional processes.
