Overview
Background & policy context:
This research project is focused on the mechanisms of road drainage during intense precipitation. By means of rainfall experiments and specific measurements, information is yielded to verify and validate simulations performed with a two-dimensional model. The results are used to evaluate rules of road drainage.
Objectives:
The objective of the project is to provide a verification and validation of two-dimensional model simulations according to depth of water on roads during intense rainfall. Furter the project has following objectives:
- collection of information on hydraulic roughness of different pavements
- collection of information on the susceptibility of aquaplaning on different pavements
- evaluation of rules for testing the capacity of inlets
Methodology:
The methodology presumes the following elements:
- Analysis authoritative test parameters such as longitudinal and transverse gradients, curve radii, cross-downslope alternately, crests, troughs, roughness of the surface layer and geometry of the grids of the mud collectors and the rain intensities (intensities in accordance with standard and hydroplaning-related precipitation events)
- Development of an experimental concept for efficient test execution
- Search of favorable trial sites regarding feasibility, the decisive test parameters and an efficient implementation
- Comparison of measured and calculated using a computerized 2D model water gauges
- Analysis of the watercourse at the edge termination and the inflow of waste water into the street sludge collectors
