According to engineering practice, the modeling is conducted separately in terms of three parts: the air buffer layer, the outer air circulation layer and the inner air circulation layer (as is shown in figures 3, 4 and 5).The three dimensions of the air buffer layer are 21m*16*1m, with 10 air inlets (400mm*500mm) evenly distributed around the layer and 2 air outlets (200*200) at top center.

The interventions to be completed are, in addition to the treadmill in via Giudecca, which is currently active from the Lungomare to Via Filippini, the creation of three other Treadmill (Stazione Lido up to the United Hospitals, University Town and connecting the areas of Engineering, Architecture and Agriculture Faculty), a train station nearby Via Giudecca, at the height of the treadmill, multi-storey car parks exchange (Museum of Sales, twain via Possidonea two at the Riuniti Hospital, one in Piazza Garibaldi and another one at the pinewood Zerbi, one in the area of Ce.Dir., and the new courthouse and another at the end of Viale della Libertà), a series of interventions to improve the traffic flow related to the railway line (all level crossings in urban area will disappear, allowing a better traffic flow and a better use of the coast and sea in the south area of the city), an important intervention linked to the project of city waterfront (to put underground the Central station) and
Specific 5.1) by the Presidency of the Council of Ministers - Civil Service Department (DPF) - Office of Personnel Training (PA UFPPA).

From the viewpoint of uncertainty in the simplified effect of the pressure wave from the explosion, even such a simplification is acceptable and justified for an engineering estimate of the explosion effects.
