As a research model, documentation for DHSVM is limited and subject to change. However, the goal is to make the documentation complete enough to enable users to implement their model without direct assistance from the developers. If you find any mismatch between the document and what the model actually does, if certain features are undocumented, or if you would like to add documentation based on your own experience, email us or post to the DHSVM GitHub page.
For a detailed introduction to principle concepts and components that lie under the framework of DHSVM, please refer to the document "The distributed hydrology soil vegetation model." This document can also be viewed through this Google Book page. Note that this document applies to DHSVM version 2.0 and was last updated in 2002.
