HIGH-FREQUENCY IN-STREAM NITRATE SENSING TO ADVANCE MODELS AND INFORM WATERSHED MANAGMENT

precision conservation has the potential to dramatically reduce nonpoint source nutrient pollution. by combining high-spatial resolution geospatial data and high-frequency instream nutrient data, we will be able to develop understanding of hot spots and hot moments of nutrient pollution. data will include high-frequency time series of nitrate concentration, discharge, dissolved oxygen, electrical conductivity, and par at stream reach (upstream and downstream of csa), subcatchment, and subwatershed scales. spatial data will include high-resolution (1m2) data of hotspots and potential bmp locations to mitigate pollution. a more systematic understanding of how multiple hydrological and biogeochemical processes control c-q patterns across multiple spatial and temporal scales is required for effective watershed management strategies.
