In times of climate change, extreme weather events are becoming more frequent - and often also the associated rainfall, which presents architects and engineers with new challenges when planning buildings. It is therefore important to calculate the drainage correctly.
The results are a critical factor in the planning and construction of buildings, roads or other public traffic areas. An incorrect result can lead to significant consequences such as flooding, erosion and damage to structures.
But which parameters are essential for a correct calculation? And what different types of drainage concepts are there? In this article, we break down all the relevant factors for a correct calculation.
The most important facts in brief
Correct calculation of the drainage is essential for safe building operation
The relevant guidelines are set out in DIN 1986-100
Modern software solutions increase efficiency and accuracy in the design of complex systems
How does a drainage calculation work?
Drainage calculation is a complex process in which various factors must be taken into account to enable an accurate prediction of drainage behavior.
The first step in the calculation is to analyze the terrain profile and determine the slope. The slope of the terrain is an essential part of the design, as it determines how quickly water can drain away.
This is followed by an analysis of the precipitation pattern in the region. This includes factors such as the frequency and intensity of rainfall as well as the type of precipitation. This data is integrated into a corresponding formula to calculate the maximum amount of runoff that can be expected.
