基于CorelDRAW软件的小流域模型雨滴测量试验研究

Measurement of raindrop distribution of watershed model using corelDRAW

降雨雨谱的观测,是了解降雨特性的一项重要工作。修建小流域模型,是对小流域进行各种试验研究的有效手段。该文基于相似率要求,在模型降雨雨滴较小,雨谱参数难以测定问题的基础上,运用CorelDRAW软件与传统色斑法相结合,探索出一种新的测量与数据处理方法,并得出不同情况下模型的雨谱特性。该法提高了测量精度,并减少了工作量。

Raindrop spectrum observation is a key to acquiring the raindrop characteristics. To build small watershed model is an effective way to do experiment in all kinds of small drainage areas. Based on the similitude ratio and the small raindrop of model rain- fall and the difficulty of measuring raindrop spectrum characteristics, the authors tried to use traditional Color-spot method with CorelDRAW to form a new method for data processing and obtained the raindrop spectrum characteristics, It proves that the new method can improve measuring precision and reduce the workload greatly.
