Project Details


The Water, Energy, and Biogeochemical Budgets (WEBB) Program was started
in 1991 at five small watersheds in the United States to examine water, energy,
and biogeochemical fluxes and to determine the effects of atmospheric
deposition, climatic variables, and human influences on watershed processes. The five sites are at Loch Vale, Colorado; Luquillo Experimental Forest, Puerto
Rico; Panola Mountain, Georgia; Sleepers River, Vermont; and Trout Lake,
Wisconsin. These sites are supported, in part, by other programs in the
USGS, other Federal and State Agencies, and Universities.

The Puerto Rico research site consists of the 113 square-kilometer Luquillo
Experimental Forest (LEF), administered by the U.S. Forest Service, and
the nearby Río Grande de Loíza drainage basin, an urbanized and agriculturally-
developed watershed. This combined region serves as a terrestrial
laboratory for the study of issues related to the global loss of tropical
forest, and the associated changes in land-use practices. Findings from
the WEBB research help scientists understand how vegetation, landscape,
and people interact to affect the quantity and quality of water and the
erosion of the landscape. The results of this work can be applied not only
to Puerto Rico, but also to many other regions, where deforestation and
rapid land-use change are issues.
