The present disclosure provides an in-situ observation system for a bottom boundary layer (BBL) over a shallow-water cohesive seabed and an arrangement method thereof. It establishes a low-cost and easy-operation hydraulic pile foundation system (2), which can ensure the piling depth to achieve the anti-settling and stability. The stainless-steel sticks are assembled freely to construct the interference-free observation unit (1). As the porous discs are used between the feet of the observation unit (1) and the top of the bottom piles, the observation system can be accurately fixed to the pile foundation. It is thus not limited by the self-weight and can integrate various instruments upon requirement. The components in this system can be easily obtained and conveniently maintained. The present disclosure has the advantages of low-cost and stability, can be widely used for long-term in-situ observation of the BBL.

Disclosed is a device and a method for measuring stream water depth in real-time through positioning data filtering to ensure the reliability of the measured water depth data even when the stream water depth measurement data is filtered and applied to a small stream having a small basin area and a steep slope. The device for measuring stream water depth in real-time through positioning data filtering includes: a measuring part for measuring the water depth of a stream to be measured; a positioning data filtering part for filtering the water depth data measured by the measuring means by a local linear regression-based bivariate scatterplot smoothing technique through elastic bandwidth application; and a water depth calculating part for calculating a water depth of the stream to be measured by using the positioning data filtered by the positioning data filtering part, and minimizing the uncertainty of the water depth measurement.

Described here are systems and methods that utilize visual imagery and an optical flow-based computer vision algorithm to measure river velocity in streams or other flowing bodies of water. The systems and methods described in the present disclosure overcome the barriers of conventional flow measurement techniques by providing a fast, non-intrusive, remote method to measure peak flows.
