Hi guys,

I am looking for low-cost methods to measure stage in rivers and streams, and was wondering if anyone has had any success?  Neil’s transducers look great, but are too expensive for our needs.  The goal is to develop a rating curve and use it to calculate loads.

Has anyone had any success with cheap pressure transducers available on Alibaba, e.g. https://www.aliexpress.com/item/4000105201818.html?spm=a2g0o.productlist.0.0.68941df6H1t6jJ&algo_pvid=3ff97d9a-1a6a-428d-a03f-2646608c7e70&algo_expid=3ff97d9a-1a6a-428d-a03f-2646608c7e70-7&btsid=0ab6fab215984240076037515ec03c&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_?

Further, has anyone seen this paper https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2019WR026810?  They suggest that a Garmin LIDAR-Lite may be able to measure river stage.  There are other, cheaper, LiDAR sensors such as this one https://www.seeedstudio.com/Seeedstudio-Grove-TF-Mini-LiDAR.html, and I wonder if they may be worth a shot.

Thanks in advance for your help.
