Resource-saving strategy of spring flow regulation
Abstract
The issues of artificial regulation of underground spring runoff are considered, the basic ecological and hydrogeological requirements to regulation systems based on resource-saving approach to groundwater use are formulated. It is shown that regulation of spring runoff should be carried out in the direction of redistribution of intra-annual underground runoff. Mathematical expressions for target functions of regulation are given. The proposed strategy is illustrated by the example of regulation of groundwater flow in the valley of the Strelka River at the Izhora groundwater deposit. By means of numerical modeling it is shown that in the conditions of this field the creation of hydraulic barrage and direct impact on the spring funnel is the most promising.
