Abstract. Recently, the water disaster in cities especially in Chinese
mountainous cities is more serious, due to the coupling influences of
waterlogging and regional floods. It is necessary to study the surface
runoff process of mountainous cities and examine the regional drainage
pipeline network. In this study, the runoff processes of Lincheng county
(located in Hebei province, China) in different scenarios were simulated
through Mike Urban model. The results show that all of the runoff process of
the old town and the new residential area with larger slope, is significant
and full flow of these above zones exists in the part of the drainage
pipeline network; and the overflow exists in part of the drainage pipeline
network when the return period is ten years or twenty years, which
illuminates that the waterlogging risk in this zone of Lincheng is higher.
Therefore, remodeling drainage pipeline network in the old town of
Lincheng and adding water storage ponds in the new residential areas were
suggested. This research provides both technical support and decision-making
reference to local storm flood management, also give the experiences for the
study on the runoff process of similar cities.
