Dry Ditch: A Stone Path When It's Not Raining

A drainage path that is mostly dry. It is a shallow, wide groove, with its bottom paved with pebbles and gravel of varying sizes, and its sides lined with flood-tolerant herbaceous plants. When there is no rain, it appears as a line of stones, traversing through grass and under trees. During heavy rain, water flows within it, and the gaps between the stones slow down the flow rate. It replaces underground drainage pipes. Avoid: using concrete U-shaped channels with covers, arranging stones in neat patterns, making the sides of the groove steep and straight, adding neat bridges and stepping stones over the groove.

一條大部分時間沒有水的排水路徑。它是一道淺而寬的凹槽,底部鋪著大小不一的卵石與礫石,兩側是耐淹的草本植物;沒有下雨的時候它就是一條石頭的線,穿過草地與樹下;下大雨時水在裡面流動,石頭之間的縫隙把流速拖慢。它取代了地下的排水管。避免:使用混凝土 U 型溝與蓋板、把石頭排列成整齊的圖案、讓溝的兩側做成陡直的邊、在溝上加設整齊的橋與踏板。
