AB: Relatively simple (parsimonious) watershed models are often adequate for many modeling objectives, e.g. flood forecasting or low-flow predictions. They can yield similar performances as more complex models, but have better identified parameters which makes them easier to calibrate and more suitable for regionalization studies, i.e. a potential application to ungauged watersheds. We present a Matlabr toolbox combining a modular framework for parsimonious watershed modeling with an analysis tool that allows for sensitivity and uncertainty analysis in a Monte Carlo framework. The modular modeling environment makes the toolbox ideal for comparison and ensemble forecasting studies including multiple model structures. Several case studies in which the tool is applied to a variety of hydrologically very different watersheds will be presented. The watersheds range from humid to semi-arid, and from fast responding clay to ephemeral chalk.
