A measurement device and method for measuring subsurface flux based on temperature tracing

Abstract

The invention discloses an undercurrent flux measurement device and method based on temperature tracing to solve the problem that an undercurrent belt is difficult to observe and quantize and achieve convenient, fast, economical, accurate and pollution-free undercurrent flux measurement with time and space continuity based on the temperature tracing technology. The measurement device comprises a testing rod, a plurality of temperature sensors and a computer, and further comprises a plurality of sealing bags and a binding agent, a plurality of installation grooves are formed in the testing rod in the length direction, and the temperature sensors are arranged in the sealing bags and installed in the installation grooves through the binding agent. The undercurrent flux measurement device is simple in structure, convenient to operate, low in processing cost and high in applicability. By means of the measurement method, the undercurrent fluxes at different depths of the undercurrent belt can be accurately measured.

Description

technical field [0001] The invention belongs to the field of groundwater science and technology, and relates to a measuring device and a measuring method for subsurface flux based on temperature tracing. Background technique [0002] The hypoflow zone is the water-saturated sediment layer in the river bed, the area where the surface water and groundwater of the river interact, and the area where the river bed can exchange material and energy with the river. In recent years, in areas with serious surface water pollution, groundwater pollution is also very serious. In addition, the construction of water conservancy projects such as river regulation and dam construction will affect a wide range of surrounding areas, not only destroying the ecological environment of the river bank, but also affecting the groundwater system and the subsurface flow zone. These will seriously threaten the safety of drinking water sources. [0003] It affects people's lives and poses potential haz...
