Abstract：

In　order　to　improve　rainfall-runoff　simulations　in　urban　area　and　enhance　the　details　of　digitalized　urban　area　with　complicated　land-surface　characteristics,　this　study　selected　the　core　district　of　Yizhuang　Economic　Development　Zone　in　Beijing　as　the　study　area,　and　the　methodology　of　sub-catchment　division,　generalization　of　drainage　pipe　networks,　and　identification　of　outfall　drainage　wells　was　proposed　for　large-scale　urban　regions　larger　than　10　km2　with　complicated　land-surface　characteristics,　in　which　local　geographical　properties,　regional　waterlogging　characteristics,　and　critical　information　such　as　digital　elevation　model,　drainage　pipeline　networks,　and　land-use　types　were　considered.　This　study　provides　technical　support　for　the　researches　on　rainfall-runoff　simulation　and　disaster　warning　in　urban　areas　where　pipeline-flow　observations　are　sparse　in　China.　©　2019,　Editorial　Board　of　Advances　in　Water　Science.　All　right　reserved.
