Isabella Anak Gisen, J. (author), Savenije, H.H.G. (author), Nijzink, R.C. (author)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...journal article 2015

Edixhoven, J.D. (author), Gupta, J. (author), Savenije, H.H.G. (author)Phosphate rock (PR) is a finite mineral indispensable for fertilizer production, while P (phosphorus) is a major pollutant if applied or discharged in excess, causing widespread eutrophication (Carpenter and Bennet, 2011). High-grade PR is obtained from deposits which took millions of years to form and which are gradually being depleted....journal article 2014

Gharari, S. (author), Shafiei, M. (author), Hrachowitz, M. (author), Kumar, R. (author), Fenicia, F. (author), Gupta, H.V. (author), Savenije, H.H.G. (author)Many environmental systems models, such as conceptual rainfall-runoff models, rely on model calibration for parameter identification. For this, an observed output time series (such as runoff) is needed, but frequently not available (e.g., when making predictions in ungauged basins). In this study, we provide an alternative approach for parameter...journal article 2014

Gharari, S. (author), Hrachowitz, M. (author), Fenicia, F. (author), Gao, H. (author), Savenije, H.H.G. (author)Conceptual environmental system models, such as rainfall runoff models, generally rely on calibration for parameter identification. Increasing complexity of this type of models for better representation of hydrological process heterogeneity, typically makes parameter identification more difficult. Although various, potentially valuable,...journal article 2014

Gao, H. (author), Hrachowitz, M. (author), Schymanski, S.J. (author), Fenicia, F.F. (author), Sriwongsitanon, N. (author), Savenije, H.H.G. (author)The root zone moisture storage capacity (SR) of terrestrial ecosystems is a buffer providing vegetation continuous access to water and a critical factor controlling land-atmospheric moisture exchange, hydrological response, and biogeochemical processes. However, it is impossible to observe directly at catchment scale. Here, using data from 300...journal article 2014

(author)Competition for water between humans and ecosystems is set to become a flash point in the coming decades in many parts of the world. An entirely new and comprehensive quantitative framework is needed to establish a holistic understanding of that competition, thereby enabling the development of effective mediation strategies.

Cai, H. (author), Savenije, H.H.G. (author), Jiang, C. (author)As the tidal wave propagates into an estuary, the tidally averaged water level tends to rise in landward direction due to the density difference between saline and fresh water and the asymmetry of the friction. The effect of friction on the residual slope is even more remarkable when accounting for fresh water discharge. In this study, we...journal article 2014

Hrachowitz, M. (author), Fovet, O. (author), Ruiz, L. (author), Euser, T. (author), Gharari, S. (author), Nijzink, R. (author), Freer, J. (author), Savenije, H.H.G. (author), Gascuel-Odoux, C. (author)Hydrological models frequently suffer from limited predictive power despite adequate calibration performances. This can indicate insufficient representations of the underlying processes. Thus, ways are sought to increase model consistency while satisfying the contrasting priorities of increased model complexity and limited equifinality. In this...journal article 2014

Valk, M. (author), Savenije, H.H.G. (author), Tiberius, C.C.J.M. (author), Luxemburg, W.M.J. (author)In this paper we present a novel method to determine the time of occurrence of tidal slack with a GPS receiver mounted on an anchored buoy commonly used to delineate shipping lanes in estuaries and tidal channels. Slack tide occurs when the tide changes direction from ebb to flood flow or from flood to ebb. The determination of this point in...journal article 2014

Berghuijs, W.R. (author), Sivapalan, M. (author), Woods, R.A. (author), Savenije, H.H.G. (author)Recent hydrologic synthesis efforts have presented evidence that the seasonal water balance is at the core of overall catchment responses, and understanding it will assist in predicting signatures of streamflow variability at other time scales, including interannual variability, the flow duration curve, low flows, and floods. In this study, we...journal article 2014

Gao, H. (author), Hrachowitz, M. (author), Fenicia, F.F. (author), Gharari, S. (author), Savenije, H.H.G. (author)Although elevation data are globally available and used in many existing hydrological models, their information content is still underexploited. Topography is closely related to geology, soil, climate and land cover. As a result, it may reflect the dominant hydrological processes in a catchment. In this study, we evaluated this hypothesis...journal article 2014

Pande, S. (author), Arkesteijn, L. (author), Savenije, H.H.G. (author), Bastidas, L.A. (author)This paper presents evidence that model prediction uncertainty does not necessarily rise with parameter dimensionality (the number of parameters). Here by prediction we mean future simulation of a variable of interest conditioned on certain future values of input variables. We utilize a relationship between prediction uncertainty, sample size...journal article 2014

(author)The effect of river discharge on tidal damping in estuaries is explored within one consistent theoretical framework where analytical solutions are obtained by solving four implicit equations, i.e. the phase lag, the scaling, the damping and the celerity equation. In this approach the damping equation is obtained by subtracting the envelope...journal article 2014

There are several atmospheric moisture tracking methods in...journal article 2013
