Calhoun Eco-hydrology Experiments

Field Areas     

◀Prev       Next►

Three historic Calhoun experimental catchments are being re- and up-instrumented based on precipitation and runoff gauging from the 1940s to 1960s. The catchments were severely eroded and gullied and have been reforested over the last half century. The archived hydrologic records were stored in the Coweeta Hydrologic Laboratory data vault since 1962. Contemporary hydrologic responses of the catchments will be compared with those that are historic. The three experimental catchments reside within the much larger Holcombe's Branch, a tributary of the Tyger River. The Holcombe's Branch basin will be used to examine the erosion's interactions with soil carbon gains and losses.
