AI Technical Summary
Existing technologies are insufficient for accurate and stable in-situ monitoring of subsurface flow flux in soft substrate environments. Traditional methods suffer from problems such as large environmental disturbances, large measurement deviations, and easy equipment subsidence.
A biomimetic anti-settlement base, a horizontal acoustic Doppler velocity measurement unit, and a multi-channel differential pressure probe array were designed, along with a data acquisition and processing unit, to create an in-situ measurement device and method for soft-bottom subsurface flow exchange. This method acquires high-frequency three-dimensional flow velocity and head data in a non-destructive manner and establishes a dynamic permeability coefficient model for calculation.
It enables long-term, high-frequency monitoring without environmental disturbance in soft substrate environments, accurately captures dynamic changes in undercurrent exchange, improves measurement accuracy and data stability, and is suitable for various soft substrate habitats.
