| description | The invention discloses a watershed and urban flood process rapid estimation method based on an integrated unit line, and the method comprises the steps: obtaining the rainfall and underlying surface parameters of a target region, the rainfall being from the information of rainfall station observation, numerical weather forecast, radar inversion and the like; calculating basin direct runoff and urban direct runoff based on the rainfall and underlying surface parameters of the target area; calculating an area standard unit line according to the underlying surface parameters of the target area; and calculating a flood hydrograph according to the direct runoff and the regional standard unit hydrograph, and completing the estimation of the flood process of the drainage basin and the urban area after superposing a base flow process. According to the method, the flood process of a watershed and an urban area can be rapidly simulated, the gradient, watertightness and the like of the area are considered, required par |
