Valley Bottom Confinement - DEM and photo representation


Valley Bottom Confinement Introduction

Valley bottom confinement is a digital representation of valley form.  Unconfined valley bottoms generally exhibit different geomorphic features from confined valleys and thus serve different roles in the landscape.  Valley confinement may have effects on fish species distributions, sediment transport, grain size, and debris flow conveyance.   The links below briefly describe our projects using valley confinement for physical and biological applications.
