Influence of the Environment and Behavior of Bridge – River Channel System

Abstract

The article highlights the importance of studying over time the bridge – river channel interaction zone, the place where a series of events and phenomena occur resulting in serious condition or collapse of bridges.
The introductive part, presents a number of damaged bridges, where the main cause was the scouring of the foundations combined with decrease of the riverbed level due to several causes, including illegal or incorrect exploitation of ballast excavations.
The second part analyzes the computer based informational system (informatics system). Simultaneously, the importance of databases use is detailed, especially for the study of the phenomena connected to bridge – river channel interaction zone.
The final part of the article present the databases required to an efficient informatics system, specific to bridge – river channel interaction mainly the database with information concerning the behavior in time of bridge in interaction zone.
