AI Technical Summary
In high-salinity and high-sand environments, traditional acoustic signals suffer severe attenuation, leading to large errors in water depth measurement. Furthermore, the lack of decoupling of multi-parameter coupling interference affects the accuracy of flow meters and velocity profilers. Existing methods have failed to effectively solve the problem of accurate measurement of hydrological elements.
A sound attenuation model was established using a multi-frequency sonar array. The parameters were optimized using a dynamic weighted fusion algorithm and a residual minimization inversion method. Combined with multi-sensor cross-validation, accurate measurement of water depth and flow velocity was achieved.
It improves the accuracy of underwater topography and flow measurement, resolves the contradiction between penetration and resolution in highly turbid water bodies, and provides more accurate hydrological and ecological monitoring and irrigation area water resource scheduling solutions.
