I'm a bit late on this, but the December 1, 2009, Geomorphology special volume: Understanding earth surface processes from remotely sensed digital terrain models, edited by Paolo Tarolli, J Ramon Arrowsmith and Enrique Vivoni is an excellent collection of papers related to the study of geomorphic processes with terrestrial laser scanning, airborne lidar, and satellite-based topographic remote sensing.
Ramon kindly provides a link to the volume's preface for those who are interested.
