1. So, it is practical to use the sequential clustering and Markov model to forecast the river runoff. 这说明运用马尔可夫模型进行河径流量的丰枯状态预报是有效可行的。
2. Roof runoff water quality was affected by rainfall, rainfall intensity, roof material, season and air temperature. 屋面径流水质主要受降雨量、降雨强度、屋面材料、季节和气温的影响。
3. Disturbance of the bedrock changes drainage and runoff patterns, which may increase the rate of erosion. Trenching is the exploration activity that most disturbs bedrock. 干扰的基岩排水和径流的变化模式，这可能增加侵蚀率。挖沟是勘探活动，大部分干扰的基石。
