Gharari, S. (author), Fenicia, F. (author), Hrachowitz, M. (author), Savenije, H.H.G. (author)This paper presents a new type of hydrological landscape classification based on dominant runoff mechanisms. Three landscape classes are distinguished: wetland, hillslope and plateau, corresponding to three dominant hydrological regimes: saturation excess overland flow, storage excess sub-surface flow, and deep percolation. Topography, geology...journal article 2011

Pande, S. (author), Savenije, H.H.G. (author), Bastidas, L.A. (author), Gosain, A.K. (author)Inapplicability of state of the art hydrological models due to scarce data motivates the need for a modeling approach that can be well constrained to available data and still model the dominant processes. Such an approach requires embedded model relationships to be simple and parsimonious in parameters for robust model selection. Simplicity in...journal article 2011

Van der Ent, R.J. (author), Savenije, H.H.G. (author)It is difficult to quantify the degree to which terrestrial evaporation supports the occurrence of precipitation within a certain study region (i.e. regional moisture recycling) due to the scale- and shape-dependence of regional moisture recycling ratios. In this paper we present a novel approach to quantify the spatial and temporal scale of...journal article 2011

Van der Ent, R.J. (author), Savenije, H.H.G. (author), Schaefli, B. (author), Steele-Dunne, S.C. (author)There has been a long debate on the extent to which precipitation relies on terrestrial evaporation (moisture recycling). In the past, most research focused on moisture recycling within a certain region only. This study makes use of new definitions of moisture recycling to study the complete process of continental moisture feedback. Global maps...journal article 2010

Savenije, L.B. (author), Ashuri, T. (author), Van Bussel, G.J.W. (author), Staerdahl, J.W. (author)The installation of floating wind farms in deeper water is encouraged by the stronger and steadier wind, the lower visibility and noise impact, the absence of road restrictions, but also the absence or shortage of shallow water. In the summer of 2009, the first large-scale floating wind turbine ”Hywind” was installed. Hywind is a spar-buoy...conference paper 2010

Uhlenbrook, S. (author), Savenije, H.H.G. (author), Makurira, H. (author)Smallholder rainfed farming systems generally realise sub-optimal crop yields which are largely attributed to dry spell occurrences during crop growth stages. However, through the introduction of appropriate farming practices, it is possible to substantially increase yield levels even with little and highly variable rainfall. The presented...journal article 2010

Winsemius, H.C. (author), Schaefli, B. (author), Montanari, A. (author), Savenije, H.H.G. (author)This paper presents a calibration framework based on the generalized likelihood uncertainty estimation (GLUE) that can be used to condition hydrological model parameter distributions in scarcely gauged river basins, where data is uncertain, intermittent or nonconcomitant. At the heart of this framework is the conditioning of the model parameters...journal article 2009

Fenicia, F. (author), Savenije, H.H.G. (author), Avdeeva, Y. (author)OA-Fund TU Delft The objective of this paper is to investigate the time variability of catchment characteristics in the Meuse basin through its effect on catchment response. The approach uses a conceptual model to represent rainfall-runoff behaviour of this catchment, and evaluates possible time-dependence of model parameters. The main...journal article 2009

A high spatial and temporal resolution data set has been gathered in a previously ungauged catchment. This data was analysed using a multi-method approach, to gather information about the processes that generated the flood...journal article 2009

Gerrits, A.M.J. (author), Savenije, H.H.G. (author), Veling, E.J.M. (author), Pfister, L. (author)The Budyko curve is often used to estimate the actual evaporation as a function of the aridity index in a catchment. Different empirical equations exist to describe this relationship; however, these equations have very limited physical background. The model concept presented in this paper is physically based and uses only measurable parameters....journal article 2009

(author)OA-fund In this study, land surface related parameter distributions of a conceptual semi-distributed hydrological model are constrained by employing time series of satellite-based evaporation estimates during the dry season as explanatory information. The approach has been applied to the ungauged Luangwa river basin (150 000 (km)2) in Zambia....journal article 2008

Friesen, J.C. (author), Van Beek, C. (author), Selker, J. (author), Savenije, H.H.G. (author), Van de Giesen, N. (author)A method for measuring whole-tree interception of precipitation is presented which employs mechanical displacement sensors to measure trunk compression caused by the water captured by the tree. This direct and nondestructive method is demonstrated to be sensitive to less than 5 kg of interception field tests in Netherlands and Ghana.journal article 2008

Schoups, G. (author), Van de Giesen, N.C. (author), Savenije, H.H.G. (author)A common concern in hydrologic modeling is overparameterization of complex models given limited and noisy data. This leads to problems of parameter nonuniqueness and equifinality, which may negatively affect prediction uncertainties. A systematic way of controlling model complexity is therefore needed. We compare three model complexity control...journal article 2008
