Abstract
Abstract. The present study is part of the preliminary investigation to design a coastal protection for the archaeological sites of Sabratha and Leptis Magna and the hydraulic re-arrangement of the final stretch of the Wadi Lebda which runs across the archaeological area of Leptis Magna. This study is a part of the project "Safeguarding the Sabratha and Leptis Magna archaeological sites. Preventing flooding of Leptis Magna from the Wadi Lebda", started in 2009 and commissioned by MARCO POLO STORICA LTD – Scotland. The planning of interventions has required an accurate morphological reconstruction of the interested areas. In this regard, given the wide investigation area, the aerial and land survey operations logistic difficulties and tight timeframe, the use of multi-beam technology and satellite images was particularly useful. The Digital Terrain Model has been coupled with detailed bathymetric surveys of the coastal area, undertaken mostly by multi-beam techniques, and by investigations of the ground characteristics, which were integrated in the information system prepared as design support.

Summary
The coast lines of the UNESCO archaeological sites of Sabratha and Leptis Magna in Libya are subjected to severe erosional phenomena, with consequent damage and deterioration effects of the historical items. The site of Leptis Magna is a coastal area, approximately 100 km to the east of Tripoli, the archaeological site seafront extends approximately 2.6 km and is characterized by alternating beaches and rocky capes (Vita-Finzi, 1969). An accurate reconstruction of the current topographical and bathymetric characteristics of the two archaeological sites’ coastal areas and the morphology of the Wadi Lebda basin have been necessary.
