filtration coefficient

In conditions of intensive increasing of urbanized impervious areas, stormwater management became especially relevant. To solve this problem, a number of methods have been developed and investigated, which are based on the retention, detention or filtration of stormwater runoff. Stormwater management by the pervious pavements is an effective method to control surface runoff; it is widely used in foreign practice, allowing to reduce the runoff volume, provides its preliminary treatment, improves the safety on the roads.
