探讨了利用数学高程模型识别流域分水线、确定坡面水流方向以及计算流域参数的方法。
A method of distinguishing watershed borderline, of ascertaining water flow direction on a slope, and of calculating watershed parameters with digital elevation model is introduced and discussed.
成果具有较好的精度，在一定程度上反映出横水流方向的水位流量变化，为防洪水利计算开辟一条新的途径。
The solution results, in satisfactory accuracy, roughly reflect the lateral variation of water stage and flow discharge This model may be used as a new method for flood control calculation.
