Determining the vehicle instability risk in stream crossings

Abstract Floods negatively affect roads, vehicles and transport systems in general. The impact on these systems leads to a cascasing effect with significant repercussions. Due to this, the evaluation of the instability risk to which the vehicles are subjected in stream crossing is necessary for the...
