New publication in Water Resources Research

The relationship between species concentration (C) and discharge (Q) can be studied through so-called C-Q curves that plot concentration over discharge.  In a new paper in Water Resources Research, Zexuan Xu and colleagues (including Ilhan Özgen, Theoretical Ecohydrology Lab) analyse the C-Q curve of a catchment in Colorado, USA, by means of a hydrological model. Differences in the C-Q curve between wet and dry years can be traced back to vertical mineral heterogeneity in the soil.
