对美国东部硬木截留降雨的所有现有报告进行了审查，并在可能的情况下进行了合并。从这些独立设计和分析的实验结果表明，硬木穿透和茎流变化在一个令人惊讶的范围内。组合回归分析描述了总降雨量（P），穿透雨（T）英寸之间的关系。夏季树干茎流（S）为T = 0.901P - 0.031，S = 0.041P - 0.005，冬季为T = 0.914P - 0.015，S = 0.062P - 0.005。这些方程可以根据特定的森林条件或季节性降雨量进行修改。15个标准量具被认为是必要的采样生长季节穿透5%的误差范围内，和6个是必要的休眠季节。硬木凋落物拦截，研究不足，在东部大部分地区，在阿巴拉契亚山脉南部的年降雨量的2%至5%。方程的研究和实际问题的适用性进行了讨论，以及需要进一步研究。
All available reports of rainfall interception by hardwoods of the eastern United States were reviewed and, where possible, combined. Results from these independently designed and analyzed experiments showed that hardwood throughfall and stemflow vary over a surprisingly narrow range. Combined regression analysis describes the relation between inches of gross rainfall (P), throughfall (T). and stemflow (S) for summer as T = 0.901P - 0.031, S = 0.041P - 0.005; for winter as T = 0.914P - 0.015, S = 0.062P - 0.005. These equations can be modified for specified forest conditions or for use with seasonal rainfall. Fifteen standard gages were found necessary to sample the growing season throughfall within 5% error limits, and 6 were necessary for the dormant season. Hardwood litter interception, studied inadequately in most parts of the east, amounted to 2 to 5% of the annual rainfall in the southern Appalachians. Applicability of equations to research and to practical problems is discussed as well as need for further research.
