在北欧的许多地方，人工排水对于建立人工林业是必要的。来自一个小型研究流域的数据表明，这种排水改变了流量的时间和总量。由于风暴之间的流量增加（基流增加了一倍），年径流增加。在暴风雨期间，开放式排水沟有助于快速消除表层水流，从而缩短水流响应时间并提高峰值。树木尚未成熟，这些结果主要指排水沟的影响，但有证据表明，由于树木的生长以及排水沟植被的生长损害了其水力效率，这些变化的幅度随着时间的推移而减小。
In many parts of N. Europe artificial drainage is necessary to establish plantation forestry. Data from a small research catchment indicates this drainage altered both the timing and the total quantity of flow. Annual runoff increased due to the augmentation of flows between storms (baseflows were doubled). In storm periods the open drains helped to quickly remove surface layer flows, leading to shorter flow response times and higher peaks. The trees are not yet mature and these results refer mainly to the effects of the drains but there is evidence that the magnitude of these changes decreases over time due to tree growth and as vegetation colonisation of the drains impairs their hydraulic efficiency.
