Embodiment

[0091] Such as figure 1 As shown, the present invention provides a simulation device for lateral subsurface flow exchange process in the riparian zone based on dye tracer. The device includes a plexiglass tank, a water level control component and a dye tracer monitoring component.

[0092] In this example, the plexiglass tank is made of transparent plexiglass, the thickness of the plexiglass is 2 cm, and a transparent adhesive scale is pasted on the outer wall of the front panel of the tank body. The scale has a waterproof function, so as to observe the water level and the migration track of the dye tracer.

[0093] Such as figure 2 As shown, the organic glass tank is composed of organic glass tank parts C and organic glass tank parts G which are perpendicular to each other. To simulate the river course, the other side of the plexiglass trough part G is provided with a second permeable sand retaining plate, which divides it into two internal spaces, which are used to simulat...

Abstract

The invention relates to a riparian zone lateral undercurrent exchange process simulation device based on dye tracing. The device comprises an organic glass tank main body composed of an organic glass tank component C and an organic glass tank component G which are vertically arranged in a T shape and are internally connected with each other, a water level control assembly and a dye tracing monitoring assembly, wherein the water level control assembly includes a water supply unit and a water discarding unit which are connected with water inlets and water outlets in the side walls of the organic glass tank component C and the organic glass tank component G; and the dye tracing monitoring assembly includes a camera arranged on the front side through a triangular support and transparent viscous graduated scales attached to front side panels of the organic glass groove component C and the organic glass groove component G respectively, and the dye tracing monitoring assembly is used for observing changes of the water level and the undercurrent exchange range and migration tracks of dye tracers. Compared with the prior art, the device has the advantages of non-intrusive monitoring, fine observation in the whole process, simplicity and rapidness in operation, quantitative description of a dynamic process and the like.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering experiments, in particular to a simulation device for lateral subsurface flow exchange process in riparian zones based on dye tracing. Background technique [0002] The riparian hypoflow zone is a water-saturated sediment layer in the riparian zone. It is a hotspot where river water and groundwater interact. Along with material transport, energy transport and biogeochemical reactions, it is of great significance to the ecosystem health of rivers and banks. [0003] At present, the research on the lateral subsurface flow exchange process in the riparian zone mainly uses seepage monitoring, water pressure monitoring, temperature monitoring, solute monitoring and other means. Although the monitoring methods are different, sensors, such as seepage meters, water pressure meters, temperature sensors, conductivity meters, etc., are usually deployed in the riparian zone sediment or ...
