Studies of Runoff Generation in the Seasonal Tropics- Panama

Prof. Fred Ogden has a project to examine the factors that produce surface runoff in the seasonal tropics. This research is being performed in Panama in the Rio Chagres watershed, which produces most of the runoff that feeds the Panama Canal.

Understanding of processes in the seasonal tropics are very important, because those regions of the earth are responsible for a significant portion of the hydrologic/carbon cycle on the planet. Hydrologic understanding in the tropics is poor because of a relative sparsity of data sets- this is why Prof. Ogden is working in Panama. The present Authoridad del Canal de Panama (ACP) and its' precursor, the U.S. Panama Canal Authority have maintained an excellent hydrologic data set that goes back almost 100 years.

Prof. Ogden is currently maintaining an extensive hillslope scale data collection network near Gamboa, Panama. This network includes: eddy-correlation evapotranspiration flux tower, and numerous soil moisture, throughfall, stemflow, groundwater level, and runoff measurement sites. Graduate students accompany Prof. Ogden to the site four to six times per year for extensive field investigations.
