Selecting model formulations and parameterizations: Reducing the need for calibration using open data and landscape characteristics

The need for calibration of conceptual hydrological models on river discharge is still large, and the scope of this research is to reduce this need based on new parameter estimation techniques, additional information sources and hydrological understanding. In a first step, a regularized model and an adjusted regularized model with sub-grid...

Constraining Conceptual Hydrological Models With Multiple Information Sources

The calibration of hydrological models without streamflow observations is problematic, and the simultaneous, combined use of remotely sensed products for this purpose has not been exhaustively tested thus far. Our hypothesis is that the combined use of products can (1) reduce the parameter search space and (2) improve the representation of...

The evolution of root-zone moisture capacities after deforestation: A step towards hydrological predictions under change?

The core component of many hydrological systems, the moisture storage capacity available to vegetation, is impossible to observe directly at the catchment scale and is typically treated as a calibration parameter or obtained from a priori available soil characteristics combined with estimates of rooting depth. Often this parameter is...

Revised predictive equations for salt intrusion modelling in estuaries

For one-dimensional salt intrusion models to be predictive, we need predictive equations to link model parameters to observable hydraulic and geometric variables. The one-dimensional model of Savenije (1993b) made use of predictive equations for the Van der Burgh coefficient $K$ and the dispersion at the seaward boundary D0. Here we have...

Revised predictive equations for salt intrusion modelling in estuaries (discussion)

For one-dimensional salt intrusion models to be predictive, we need predictive equations to link model parameters to observable hydraulic and geometric variables. The one-dimensional model of Savenije (1993b) made use of predictive equation for the Van der Burgh coefficient K and the dispersion at the seaward boundary D0. Here we have improved...

Improving the predictive equation for dispersion in estuaries

Dispersion is often hard to incorporate in analytical salt intrusion models. The analytical models of Savenije (1986) and Kuijper & Van Rijn (2011) are quite similar and use a predictive equation for the dispersion in the estuary mouth. The biggest difference between the two models is the Van der Burgh K for which Kuijper and Van Rijn stated...
