降雨

The simulation of rainfall-runoff is an important part of hydrology simulation.

降雨径流模拟是水文模拟的重要组成部分。

In order to reasonably use design storm hyetograph in uniform area, we need to select a regionalized representative hyetograph from alternatives in uniform area.

但限於雨量测站为点的分布，因此必须将雨型设计结果分类及区域化，并求得区域代表雨型，如此方能为未设站区域使用，亦能合理的应用於降雨迳流模式中。

Several forms of design storm hyetograph have been developed in recent years. A Gauss-Markov hyetograph is based on non-stationary first-order Markov process. It is a dimensionless hyetograph and the most likely to occur is the average hyetograph.

暴雨雨型模式有许多种，本研究采用具尺度不变性之高斯马可夫雨型模式，该暴雨雨型模式视每一场降雨事件为一随机历程，考虑每个时刻之序列符合常态分布，以一阶高斯马可夫历程叙述临前水文条件的遗传效应，因此该雨型亦为具有最大概似度之设计暴雨雨型。

The study probe into at when extreme rainfall happenning incident research purpose department on city, estimate its flow of flood crest to defend and provide disaster relief the reference carried on the exercise of in follow-up ; While estimating the the depth of extreme rainfall , use separately: World Meteological Organization statistic method, storm transposition and dew point adjustment method and average recurrence interval rainfall depth factor method, inquire into and act as river valley wutu the upper reaches of Keelung and collect in the water area separately, wutu station with flood-diversion stands in the Huo-Shao-Liao station before Yuan-Shan-Tzu flood-diversion, the depth when the extreme rainfall happens separately, step forward and mix the set of design hyetograph by extreme rainfall ,finally,mix geomorphologic instantaneous unit hydrograph afterwards, in order to estimate the flow of flood crest produced cause by extreme rainfall incident .

本文之研究目的系探讨当极端暴雨事件发生於都会区时，推估其洪峰流量以作为后续防救灾演练之参考。在推估极端暴雨之降雨深度时，分别采用：世界气象组织统计法、暴雨移置与露点调整法及平均重现期距雨量因子法，分别推求当基隆河流域五堵上游集水区，员山子分洪前之火烧寮站与分洪后之五堵站，分别发生极端暴雨时之雨量，进一步将极端暴雨量套配设计雨型，最后再搭配地貌型瞬时单位历线模式，以推估因发生极端暴雨事件而产生之洪峰流量。

In addition, the hygroscopic seeding of summertime convective clouds shows some promise to enhance rainfall.

夏季对流云的吸湿性播种显示了一些承诺，以加强降雨。

Rainfalls flow along the hypsography of the earth's surface,and valley elements such as the valley lines,catchment areas and naturally.

降雨在地表上随地形流动自然形成沟谷线、汇流区、分水岭等流域形态，研究地表流水线的数字模拟对数字流域水文分析具有重要意义。

The result shows that the vulnerably geological structure of landslide body, concentrated rainfall and reservoir impoundment caused this landslide.

在内部条件具备的前提下，滑坡发生前的连续降雨及水库蓄水均使得坡体物质的力学强度降低，故引发了大规模的滑坡失稳。

Therefore, Research to change of soil's unsaturated character under rainfall and infiltration is very important.

因此，对于降雨入渗条件下土壤非饱和特性变化的研究具有十分重要的意义。

Winding into the a rid grassland , scrubby vegetation mixed with grasses , and dry , droughty soils will indicate the infrequency of rainfall Design GrouPA,1985

到了草原的边缘，混合的灌木丛与草原植被，及干燥，干旱的土壤表明这里很少降雨。

The computing methods of rainfall input and runoff generation and flow concentration in grid elements are discussed deeply.

深入探讨了单元网格的降雨输入和产汇流计算方法。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
