Short summary
Measuring flows in streams allows us to manage crucial water resources. This work shows the automated application of a dual camera computer vision stream gauging (CVSG) system for measuring streams. Comparing between state-of-the-art technologies demonstrated that camera-based methods were capable of performing within the best available error margins. CVSG offers significant benefits towards improving stream data and providing a safe way for measuring floods while adapting to changes over time.

Chamber-based flux measurements for carbon dioxide, methane, nitrous oxide and other climate-active gases show high temporal and spatial variability and there is a need for autonomous, simple and affordable systems. The author present such a device that can be constructed for a few thousands euros/dollars. The Pondi logger will facilitate greenhouse gas studies in remote places and will be excellent tools to involve citizens in our climate studies.
