Or operational hydrology in Iowa. I do not know if I like the name, because it usually distinguished, since Sacramento model, models that work but kind of far from the edge of research. Obviously this was due to the fact that having a model running every day faces issues that researchers of my type seldom love, like dealing with unreliable data sets, managing, in any case huge amount of data, calibration of parameters, and, more recently, data assimilation. This obviously has to be done routinely, with no loss of forecasting, when it is easy not to have data, and so on. So the focus of these systems was (is) operativity and having reliable results with unreliable tools (an not, like I do, improving the tools).
Among the various experience I saw around the world, The Iowa's one, is remarkable, because never forgot the most recent research, thanks to the effort of Ricardo Gutierrez Mantilla (GS), and Witold Krajesky (GS).
Ricardo, which whom I share a paper, was so kind to show me what he is doing with all the group of people in Iowa in the recent EGU meeting in Wien, and I was surprised by the quality of the results he has, and the quality of the overall system. One remarkable fact is also the this system is, certainly based on the knowledge of current literature but, originally developed and different from any other. He finally sent to me the couple of his presentation that I (under his permission) am sharing with who is interested.
