2014 Water in the Landscape Distinguished Seminar Series
Moving Forward in Nutrient Research and Management: Critical Knowledge Provided by High Time Resolution Water Quality Data
Wednesday, May 7, 2014, 10:30-11:30 am
Frazier Rogers Hall (122)
The Center for Landscape Conservation and Ecology presents Dr. François Birgand, Assistant Professor of Biological and Agricultural Engineering at North Carolina State University. Dr. Birgand will speak on "Moving forward in nutrient research and management: Critical knowledge provided by high time resolution water quality data."
In environmental management, data are the primary source to make informed decisions. But how informed are we? Data acquisition is always partial in time and in space. Ideally monitoring schemes are designed such that uncertainties associated with limited data be known or thought to be small enough to make meaningful conclusions. That is the theory. In practice (and historically) water quality data tend to be acquired on a rather infrequent basis. Consequently, large uncertainties may stain results. In fact, we believe discontinuous information on water quality is halting our ability to make proper Environmental Management decisions.
This seminar will illustrate what high frequency monitoring can provide in terms of potential management leaps forward, and a contrario, illustrates potential erroneous conclusions which could be reached from less frequent data. We will present high frequency data obtained from new optics based systems which have become more widely available. These instruments now open the possibility to obtain data at a temporal resolution in par with that commonly used in quantitative hydrology (e.g. 15 min).

Dr. François Birgand received his PhD from North Carolina State University in 2000 in Agricultural Engineering. He has been an assistant professor with North Carolina State since 2008. He specializes in biogeochemistry and ecological engineering, hydrology and water quality monitoring, and sampling strategies in watersheds.
