Photos from Bear Creek field site, April 8-10, pre-irrigation NMR survey.
This is my second time assisting with surface NMR measurements at this site; last year we went in May, so the threes were already green (click for last year pics). The stream shown on the pictures is Bear Creek, a Wind River tributary. The fields are managed by Wyoming Game and Fish Department (as far as I know). The project is part of WyCEHG (Wyoming Center for Environmental Hydrology and Geophysics, University of Wyoming) and Wyoming Game and Fish collaboration. The white pipes on the pictures are for flood irrigation. Niels Claes is the the PhD student, who’s working on return-flow subsurface flowpaths characterization and quantification. Return flow is the portion of irrigation water, that returns to the system and it is not used by the plants.
