Behind every robust result is a robust method: Perspectives from a hydrological case study

Scientific studies and mathematical models are increasingly used to guide the management and development of society. But while science and modelling can indeed provide a robust basis for decision making, we must be mindful of two related considerations. First, science is based not on trust but on skepticism, meticulous technique and careful verification. Second, science is not made of absolute tru ...[Read More]

On modelers and modeling

On modelers and modeling

Several studies were conducted and are ongoing where we investigate modelers, modeling decisions and modeling perceptions. Below I discuss the rationale and a summary of the (preliminary) results. Simulation models, conceptualizations of processes into a system of mathematical equations (hereafter simply referred to as models), are frequently used tools in the hydrological sciences. The literature ...[Read More]

Sharing is caring: Models for all, presenting eWaterCycle II

The photos above were found by doing a google image search for ‘hydrologist’. Apparently our image is that of scientists that get to be outside a lot. We all know that the knowledge we gain from fieldwork gets codified in hydrological models which can be written in all sort of programming languages. “I wonder what this analysis would look like using that other groups hydrological model ...[Read More]

All models are wrong but…

All models are wrong but…

“All models are wrong but some are useful” is a quote you probably have heard if you work in the field of computational hydrology – or ‘hydroinformatics’ – the science (or craft?) of building computer models of hydrological systems. The idea is that, even if these models cannot (by definition!) be a 1:1 representation of reality, their erroneous predictions can still be useful to support decision- ...[Read More]
