The upper Río Chagres basin is a part of the Panama Canal Watershed. The least known water balance component of this watershed is evapotranspiration. Measurements of actual evapotranspiration rates on the ground are difficult and expensive. The objective of this study is to demonstrate a new inexpensive method for determination of regional evapotranspiration in the watershed. The method uses LANDSAT satellite images that are analyzed using the Surface Energy Balance Algorithms for Land (
SEBAL
). We use an image from March 27, 2000, for estimation of the distribution of the regional actual evapotranspiration in the Panama Canal Watershed and surrounding areas.
