When prospective coring reveals the presence of sites of potential archaeological interest are present in the area, a trial trench evaluation is a logical next step to determine the nature, size and quality of the site. The site is located and investigated by the digging of pits according to a strategical plan. The results of this investigation lead to a substantiated advice to the authorities regarding the next steps; release of the area, excavation or the physical preservation and protection of the site.
Combination with UXO investigation
Sometimes an archaeological site where a trial trench evaluation takes place is located in an area suspected of UXO. By properly combining and coördinating the archaeological and UXO research activities, the duration of the project can be shortened. The deployment of an archaeologist who is also a certified UXO expert ensures protection and preservation of any archaeological heritage found during the approach phase of the UXO investigation.
