Tectonic control of fan size : the importance of spatially variable subsidence rates

  title={Tectonic control of fan size : the importance of spatially variable subsidence rates},
  author={Kelin X. Whipple and Carolyn R. Trayler},
We study the geophysical controls on the size of alluvial fans. Simple relationships between catchment characteristics, sediment yield, subsidence patterns and fan size are developed. As predicting fan size is essentially a conservation of mass problem, our analysis is general, applying to all types of fan landform. The importance of spatially variable subsidence rates has gone largely unrecognized in previous studies of modern fans. Here we stress that the distribution of subsidence rates in… CONTINUE READING
