【Abstract】 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. Verifying with practically surveyed watershed data shows that the method is available and precision, and helpful for developing distributed hydrologic physic model.更多还原
