The Land Surface Hydrology Research Group at the University of California, Los Angeles is led by Prof. Dennis Lettenmaier. It is made up of seven graduate students and two post-doctoral researchers. We are part of the Department of Geography at the University of California, Los Angeles. Our main research interest is modeling and predicting the role of land hydrology in the climate system, and understanding the nature of hydrologic variability and change as they are related to changing climate and land cover/land use. We do so through a combination of hydrologic modeling, and diagnosis of contemporary and retrospective in situ and remote sensing data. While much of our work is at regional, continental, and global scales, we also have modeling and prediction interests at the small watershed scale.

This web site contains information about the interests and research of group members and collaborators, as well as recent publications, the models we use (including some documentation and contact information for source codes), some of the data sets produced by the group, and links to data sets and processing software that we use in our modeling. In addition to publications, the presentations area of this web site includes most of the presentations (oral and poster) given by members of the group from about 2000 on.
