Using An Object And Pattern Oriented Approach To Hydrological Modelling Teaching And Research, R.W. Vervoort, J.H.A. Guillaume, T.F.A Bishop, D. Kundu, F.F. Van Ogtrop

International Congress on Environmental Modelling and Software

Introducing hydrological modelling in undergraduate teaching is challenging, and some of this is related to the decline in STEM knowledge in students. Enabling students to confidently work with a range of hydrological models remains difficult, particularly if the goal is to make students understand the modelling process and model structures. The limited literature points to a number of educational tools that have been developed, falling into three classes: magical box fully developed GUIs with little insight into model operation; highly theoretical command line linear reservoir and unit hydrograph tools; and model tools focusing on one single model structure. Given the ...


Apex-Cute: An Auto-Calibration And Uncertainty Analysis Tool For The Apex Model, Xiuying Wang, Haw Yen Jun 2014

Apex-Cute: An Auto-Calibration And Uncertainty Analysis Tool For The Apex Model, Xiuying Wang, Haw Yen

International Congress on Environmental Modelling and Software

The Agricultural Policy Environmental eXtender - auto-Calibration and UncerTainty Estimator (APEX-CUTE) was developed as an open-source tool which enhances the accessibility for APEX users to conduct potentially tedious calibration work on the APEX model. The role of uncertainty analysis should be taken as an independent supporting package to extend the capability in further analytical purposes. This version of APEX-CUTE incorporates relevant functions of uncertainty analysis flexibly. Users have options to include designated uncertainty sources such as input and/or measurement errors during the calibration process. APEX-CUTE is not only the comprehensive package in performing model calibration on APEX, but it can ...


The Data Processing Inequality And Environmental Model Prediction, Steven V. Weijs Jun 2014

The Data Processing Inequality And Environmental Model Prediction, Steven V. Weijs

International Congress on Environmental Modelling and Software

Prediction in environmental systems, such as hydrological streamflow prediction, is a challenging task. Although on a small scale, many of the physical processes are well described, accurate predictions of macroscopical (e.g. catchment scale) behavior with a bottom-up mechanistic approach often remains elusive. On the other hand, conceptual or purely statistical models fitted to data often perform surprisingly well for prediction. The data processing inequality, from the field of information theory, says that processing data with statistical procedures can only decrease, and not increase the information content of the data. This seems to contradict the intuition that our knowledge of ...
