| description | The invention discloses a river water-underground water conversion relationship quantification method with low data requirements. The method comprises the following steps of calculating a basin underground water level according to monitoring data of an underground water monitoring well; adopting a riverway one-dimensional hydrodynamic model for calculating the riverway water level; segmenting river channels according to the underground water level contour line and the thickness of an aquifer, and determining the representative section of each river segment; calculating the unit width conversion quantity of surface water and underground water of the representative section of each river reach according to the Darcy law, and accumulating to obtain the conversion quantity and conversion direction of the whole river reach. The field actual measurement of the surface water level and the underground water level in the traditional calculation is broken through. The conversion amount of river water and underground wat |
