Experiments to validate BlueLog: A versatile low-cost instrument for monitoring water level in coastal applications

This database include a set of laboratoy and field experiments carried out to validate a new instrument for measuring static and dynamic water column pressure is presented here. The instrument has been named BlueLog.
Two types of pressure measurement tests were performed in the laboratory. First, hydrostatic pressure measurements were carried out during the (fast and slow) filling and emptying of a tank where the water remains at rest. Second, dynamic conditions were registered considering oscillatory flow in a wave flume (with dimensions of 25 m long, 1 m wide, and 1 m height) as waves propagate over the pressure sensors. Under hydrostatic and oscillatory flow conditions, a comparative performance analysis was carried out between BlueLog and two commercial wave/pressure sensors (RBRduo from RBR Ltd. and Aqualogger P520 from AQUATEC ltd.) to verify the reliability of the de-veloped sensor, taking as reference the commercial ones. Three different monochromatic wave heights were simulated in the wave flume for different tests: H1 = 0.07 m (Case 1), H2 = 0.10 m (Case 2), and H3 = 0.12 m (Case 3).
Afterwards, the performance of the BlueLog was also validated under field conditions in Bocagrande beach (Cartagena, Colombian Caribbean Coast) in August 26th, 2017. BlueLog and RBR sensors were deployed in the surf zone of the beach in coordinates 10.399ºN, -75.564ºE considering a mean water depth of 1.2 m. Measurements were carried out for three different sea states changing the sampling frequency in both instruments between 6 Hz (Case 4), 4 Hz (Case 5), and 2 Hz (Case 6), considering data bursts of 2048 samples for all cases.

Data in Matlab format

Three kind of validation test where carried out:
1. (Figure 5): hydrostatic pressure measurements were carried out during the (a) fast and b) slow) filling and emptying of a tank where the water remains at rest.

2. (Figure 6): dynamic conditions were registered considering oscillatory flow in a wave flume. Three different monochromatic wave heights were simulated in the wave flume for different tests: H1 = 0.07 m (Case 1), H2 = 0.10 m (Case 2), and H3 = 0.12 m (Case 3).

3. (Figure 7): Validation under field conditions in Bocagrande beach (Cartagena, Colombian Caribbean Coast). BlueLog and RBR sensors were deployed in the surf zone of the beach in coor-dinates 10.399ºN, -75.564ºE considering a mean water depth of 1.2 m. Measurements were carried out for three different sea states changing the sampling frequency in both instruments between 6 Hz (Case 4), 4 Hz (Case 5), and 2 Hz (Case 6), considering data bursts of 2048 samples for all cases.

本数据库收录了一系列实验室及实地实验，旨在验证一种新型测量静态及动态水柱压力的仪器，该仪器命名为BlueLog。实验室内进行了两种类型的压力测量测试：首先，在保持水体静止的状态下，对水箱进行（快速及缓慢）充水和排空过程中的静水压力进行了测量；其次，考虑波浪水槽（尺寸为25米长、1米宽、1米高）中的振荡流动态条件，记录了波浪传播过程中压力传感器的状态。在静水压力和振荡流条件下，对BlueLog与两款商业波浪/压力传感器（RBR Ltd.的RBRduo和AQUATEC ltd.的Aqualogger P520）进行了比较性能分析，以验证所开发传感器的可靠性，并将商业传感器作为参照。在波浪水槽中，针对不同测试模拟了三种不同单色波高：H1 = 0.07米（案例1）、H2 = 0.10米（案例2）和H3 = 0.12米（案例3）。随后，在2017年8月26日的Bocagrande海滩（哥伦比亚加勒比海岸的卡塔赫纳）实地条件下，也对BlueLog的性能进行了验证。BlueLog和RBR传感器被部署在海滩的冲浪区，坐标为10.399ºN, -75.564ºE，考虑到平均水深为1.2米。对三种不同的海况进行了测量，两种仪器之间的采样频率在6 Hz（案例4）、4 Hz（案例5）和2 Hz（案例6）之间变化，所有情况下均以2048个样本的数据爆发进行测量。文件描述：BlueLog与两款商业波浪/压力传感器（RBR Ltd.的RBRduo和AQUATEC ltd.的Aqualogger P520）之间比较性能分析的数据。文件的命名参照了相关论文中展示数据的图表编号。数据以Matlab格式提供。共进行了三种类型的验证测试：1.（图5）：在保持水体静止的状态下，对水箱进行了（a）快速和（b）缓慢的充水和排空过程中的静水压力测量。2.（图6）：记录了波浪水槽中的动态条件，考虑了振荡流。为不同测试模拟了波浪水槽中的三种不同单色波高：H1 = 0.07米（案例1）、H2 = 0.10米（案例2）和H3 = 0.12米（案例3）。3.（图7）：在Bocagrande海滩（哥伦比亚加勒比海岸的卡塔赫纳）实地条件下的验证。BlueLog和RBR传感器被部署在海滩的冲浪区，坐标为10.399ºN, -75.564ºE，考虑到平均水深为1.2米。对三种不同的海况进行了测量，两种仪器之间的采样频率在6 Hz（案例4）、4 Hz（案例5）和2 Hz（案例6）之间变化，所有情况下均以2048个样本的数据爆发进行测量。
