Meanwhile, an artificial imitation rainfall system was developed in order to study the characteristics of city underlying surface and make experimental check up about the relative appraising index, on which 200 rainfall experiments are made, analyzing the effect of rainfall intensity to the runoff of underlying surface ; the relationship between runoff permeability and unit factor of rainfall intensity and duration ; the effect of rainfall intensity, duration, soil moisture content, and temperature to the runoff permeability ; the relationship between rainfall quantity and runoff permeability, and make mathematical imitation to the expe rimental results, to find the mutual - relationships, and make discussion about the differences between equations of fit
同時，為研究城市下墊面的產匯流特性研製了一套人工模擬降雨系統，並對相關評價指標進行了實測校驗。在此基礎上，進行了200多場降雨實驗，分析了雨強、歷時、土壤前期含水量、溫度、降雨量、不同下墊面和不同覆蓋度等對產匯流的影響，及各種因素對徑流系數的影響和相關性，建立了一定條件下歷時徑流系數，雨強徑流系數，流量徑流系數的函數模型。 -
