antecedent soil water
Examples
- Therefore , there is a whole significance to study the soil erosion mechanism and to explore methods and measures to reduce the soil loss of hillslope of
研究发现壕中流的产生与降雨强度无直接关系，而与土壤前期含水量和地面坡度有关 - 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
同时，为研究城市下垫面的产汇流特性研制了一套人工模拟降雨系统，并对相关评价指标进行了实测校验。在此基础上，进行了200多场降雨实验，分析了雨强、历时、土壤前期含水量、温度、降雨量、不同下垫面和不同覆盖度等对产汇流的影响，及各种因素对径流系数的影响和相关性，建立了一定条件下历时径流系数，雨强径流系数，流量径流系数的函数模型。
