Sinkholes are a well-known geologic hazard but their past occurrence, useful for subsidence risk prediction, is difficult to define, especially for ancient historic times. Consequently, our knowledge about Holocene carbonate landscapes is often limited. A multidisciplinary study of Trieste Karst (Italy), close to early Roman military fortifications, led to the identification of possible ancient...

Forecasting is one of the main topics of an integrated traffic management system and a necessity of dynamic route planning systems. To be able to forecast properly we use both historic data and current data from monitoring devices as input for our dynamic model. Thus, combining the best of both worlds, we are a...
