Intensity and Duration of Rainfall的意思|示意

The cumulative quantity of runoff's nutrient increases correspondingly along with the more enhancing rainfall intensity and longer duration of runoff generation.

随着雨强的增大、产流时间的增加，径流养分累积量也相应增大。

The appearing and lasting time of pipe flow is related to the rainfall intensity, duration of rainfall, the previous water content of soil and the location of soil pipe in soil section.

管流出现的时间、管流历时与降雨强度、降雨历时、土壤前期水分含量和土管所处的土壤剖面位置等因素有关。

The investigation on the relationship between the stability of unsaturated soil slopes and rainfall mainly focuses on the effect of rainfall intensity, duration and rainfall amounts.

在降雨对非饱和土斜坡稳定性影响的研究中，对降雨强度、降雨持续时间和降雨量的研究比较成熟，而研究雨型对斜坡稳定性的影响比较少。

The rainfall Intensity Duration Frequency formula is one of the bases in hydrology calculation, and has been of considerable interest to engineers and hydrologists.

降雨公式是水文计算的基本依据之一，也是工程师和水文学家十分关心的问题。

It is found that the moisture of soil varies greatly and the intensity of short duration rainfall triggering debris flow changes in different part of rainfall period.

发现雨季不同时期土体含水量差异较大，而且在不同时期激发泥石流的短历时雨强也不同。

Some basic laws were certified. Different periods in duration and intensity of rainfall were studied.

除验证了一些基本规律外，还对降雨历时、降雨强度的分段进行了研究深入探讨。
