水域俾攞嚟起嘢 城市建設侵霸咗河流、護城河、湖泊等水域，加埋城區面積擴大，導致城市坑渠大量嘅雨水湧向剩低啲水域，積水唔能夠及時排走，仲可能倒灌翻地面，造成水浸。排水系統唔完善 有啲城市嘅排水系統比較落後，抑或維護不善，導致水浸。城市地面硬化 城市化過程中，大面積嘅地面臘青或水泥冚住，導致雨水滲 唔到落去，唔單止增加排水系統同自然水域嘅排水負擔，仲導致地下水水位唔夠高。有時由於硬底化，即使郊區雨量大過城區，發生水浸嘅都仍然係城區。 管理缺位 政府部門注重「形象工程」而唔理埋喺地底嘅排水系統，導致水浸問題解決唔到。
The water area has been taken to the east and west city construction encroached on rivers, moats, lakes and other waters, coupled with the expansion of the urban area, resulting in a large amount of rainwater in the urban sewers to the remaining waters, the stagnant water can not be drained away in time, and may also be poured over the ground, causing floods. Imperfect drainage systemsSome cities have poor drainage systems or are poorly maintained, leading to flooding. In the process of urban ground hardening and urbanization, a large area of ground is covered with green or cement, resulting in rainwater seepage, which not only increases the drainage burden of the drainage system and natural waters, but also causes the groundwater level to be not high enough. Sometimes, due to hard bottoming, even if the rainfall in the suburbs is heavier than in the urban areas, it is still the urban areas that are flooded. Lack of management: Government departments focus on "image works" and ignore the drainage systems buried underground, resulting in unsolved flooding problems.
