HYDRAULISCHE ZUSTANDSKLASSIFIZIERUNG DURCH RISIKOBETRACHTUNGEN

The paper presents a method to classify rehabilitation work according to urgency on the basis of hydraulic calculations of storm Water and combined wastewater networks. This method is not dependent on calculation methods (detection or dimensioning) nor on the target variable of detection (flooding or impoundment), the guiding principle is that insufficient hydraulic capacities must be classified as particularly urgent, if the existing recurrence period is clearly lower than the required recurrence period.
