Riparian zone simulating and monitoring system

Abstract

The invention discloses a riparian zone simulating and monitoring system, which belongs to the field of water conservancy project physical model test. The riparian zone simulating and monitoring system comprises a system control platform, a riparian form simulating system, a pressure monitoring system and a concentration monitoring system. The riparian zone simulating and monitoring system is convenient for forming riparian landforms of different forms quickly and researching of the flow characteristics and exchange process of surface water and groundwater at riparian zones of different forms, and contributes to saving time and labor; a special pressure monitoring system is provided with pressure sensor fixing bases of different shapes and specifications and a freely-stretchable drawer-type transverse plate, and pressure sensors can be accurately arranged on the surface of a riparian form, so that the problems of difficulty in accurately fixing the pressure sensors on the surface of a riparian sand body, easy deviation of an arrangement position and the like are solved; and a perfect test monitoring system can be used for automatically acquiring and monitoring the pressure field data and concentration field data of riparian zone physical test.

Description

technical field [0001] The invention relates to a riparian zone simulation and monitoring system, which belongs to the field of physical model tests of water conservancy projects, and is especially suitable for research fields such as riparian zone hydraulic characteristic simulation, near-shore surface water and groundwater exchange simulation, riparian zone pollution reduction effect simulation, and the like. Background technique [0002] The riparian zone is the transition zone between water and land, and an important link for the mutual transfer and transformation of materials and energy between river ecosystems and terrestrial ecosystems. When the surface water flows through the curved river bank, a pressure gradient will be generated between the upstream surface and the backwater surface of the river bank, which will promote the convective exchange between the surface water and the groundwater; when the surface water flows through the rough river bank surface, a severe ...

AI Technical Summary

Problems solved by technology

[0004] 1. It can only study the flow regime of river surface water under the action of river bank boundary, but cannot conduct research on the interaction between river surface water and river bank groundwater

[0005] 2. To change the shape of the river bank, the original model needs to be dismantled, the section formwork must be remade, and a new river bed and bank shape should be created. The model production period is long and the cost of the model is high

[0006] 3. The river bed and bank boundary where the surface water and groundwater of the river exchange are blocked by the cement mortar plastering surface, which cannot simulate the exchange phenomenon of the river surface water and the river bank groundwater under the action of various physical and chemical gradients

[0007] 4. There is no surface water and groundwater concentration monitoring system, and it is impossible to quantitatively study the net exchange volume and exchange range of river surface water and riparian groundwater
