Description / Table of Contents:
This highly topical book provides a global synthesis and integrated analysis of environmental drivers and quantitative rates of solute and sedimentary fluxes in cold environments, and the likely impact of projected climate change. It will be of interest to graduate students and researchers in the fields of geomorphology, sedimentology, and global environmental change.
