The primary research questions explore the accuracy of these technologies in measuring stage and discharge during low- and zero-flow conditions compared to conventional methods, and their application in assessing surface water network fragmentation. The project is associated with the GaugeCam GRIME Lab, with key personnel including Jessica Wilhelm, Mary Harner, Troy Gilmore, and Ken Chapman. The research utilizes time-lapse camera imagery, specifically highlighting a photo contest entry titled ‘Bison at a shrinking pool’ from the Missouri River Watershed. The study area includes South Fork Kings Creek in Kansas. Data provided includes mean daily discharge in L/s for the N4D Weir from January to October 2023. The methodology aims to provide a robust alternative or supplement to existing hydrological monitoring techniques, particularly in arid and semi-arid regions where non-perennial streams are prevalent.","Quantification of Non-Perennial Stream Flow using Time-lapse Photography and Machine  \nLearning  \nJessica Wilhelm Mar 29th, 2025  \n[wilhelmjf@ku.edu](wilhelmjf@ku.edu)  \nBig thank you to the GaugeCam GRIME Lab!  \nMary Harner University of Nebraska  \nTroy Gilmore University of Nebraska  \nKen Chapman UNL PhD (not pictured)  \n[grime.lab.ne](grime.lab.ne)  \nGaugeCam GRIME lab: [https://gaugecam.org/](https://gaugecam.org/)  \nThis month’s featured GRIME contest photo chosen from time-lapse camera!  \n‘Bison at a shrinking pool’  \nMissouri River Watershed, USA  \nPerennial streams  \nNon-perennial streams  \nSouth Fork Kings Creek, Konza  \n|  | 0 20 40 60 |\n| --- | --- |\n| N4D Weir Mean Da ily Discha rge (L/s) |  |\n\n Jan Apr Jul Oct Jan   \n2023  \nResearch Questions  \n1) To what extent can time-lapse photography and machine learning accurately measure stage and discharge during low-and zero-flow conditions, compared to conventional monitoring techniques?  \n2) How can time-lapse photography and machine learning be used to accurately measure surface water network fragmentation compared to conventional methods?  \nRQ2","cbCaikDEJOiiiDsi","https://ap.wps.com/l/cbCaikDEJOiiiDsi","pdf",2556451,1,26,"English","en",105,"# Quantification of Non-Perennial Stream Flow using Time-lapse Photography and Machine Learning\n## Research Questions","[{\"question\":\"What are the main research objectives of this study?\",\"answer\":\"The study aims to determine the accuracy of time-lapse photography and machine learning in measuring stream stage and discharge during low- and zero-flow conditions, and to assess their effectiveness in measuring surface water network fragmentation compared to conventional techniques.\"},{\"question\":\"Who are the key researchers and institutions involved?\",\"answer\":\"The research is conducted by Jessica Wilhelm, who is affiliated with the University of Nebraska.
