This study explores the effects that terracing had on the hydrology of the Monte Pallano area of Italy. This area has been inhabited for thousands of years and is the current site of the Sangro Valley Archaeological Project. Ancient terraces that the Pre-Roman (Samnite) and Roman people created as flat areas to build on and farm are common in the study area. The effects of the terraces on the local hydrology up until now were unknown. In order to discover this, two elevation models were used to create two sets of watersheds. One of the elevation models was acquired from Jamie Countryman (Oberlin College ‘12), the other was created using elevation and location data of surveyed terraces. After watersheds were delineated using ArcGIS, six watersheds were identified that showed differences when the terraces were included. These findings show that terracing had a significant effect on the local hydrology, especially because the data only accounts for a limited number of terraces, and the altered elevation model also caused them to act more like walls than actual terraces.
