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 2013

Nasalevich, M.A. (author), Goesten, M.G. (author), Savenije, T.J. (author), Kapteijn, F. (author), Gascon, J. (author)NH2-MIL-125(Ti) has been post-synthetically functionalized with dye-like molecular fragments. The new material (methyl red-MIL- 125(Ti)) exhibits improved light absorption over a wide range of the visible spectrum, and shows enhanced photocatalytic oxidation activity under visible light illumination. The consequences of functionalization and the...journal article 2013

(author), Siebbeles, L.D.A. (author)Carrier multiplication, the generation of multiple electron–hole pairs by a single photon, is of great interest for solar cells as it may enhance their photocurrent. This process has been shown to occur efficiently in colloidal quantum dots, however, harvesting of the generated multiple charges has proved difficult. Here we show that by tuning...journal article 2013

Cai, H. (author), Savenije, H.H.G. (author), Toffolon, M. (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 2013

Van der Ent, R.J. (author), Savenije, H.H.G. (author)Identifying the sources of continental precipitation has received increasing attention in recent years. With the use of various numerical methods, sources of precipitation have been identified from local to global scales. In this paper we identify the oceanic sources based on an atmospheric backtracking analysis of continental precipitation. We...journal article 2013

(author)A high-temperature procedure to hydrogenate diamond films using molecular hydrogen at atmospheric pressure was explored. Undoped and doped chemical vapour deposited (CVD) polycrystalline diamond films were treated according to our annealing method using a H2 gas flow down to ?50 ml/min (STP) at ?850?°C. The films were extensively evaluated by...journal article 2013

Fischer, B.M.C. (author), Mul, M.L. (author), Savenije, H.H.G. (author)With a growing world population and a trend towards more resource-intensive diets, pressure on land and water resources for food production will continue to increase in the coming decades. Large parts of the world rely on rainfed agriculture for their food security. In Africa, 90% of the food production is from rainfed agriculture, generally...journal article 2013

Van der Ent, R.J. (author), Tuinenburg, O.A. (author), Knoche, H.R. (author), Kunstmann, H. (author), Savenije, H.H.G. (author)This paper compares three state-of-the-art atmospheric moisture tracking models. Such models are typically used to study the water component of coupled land and atmosphere models, in particular quantifying moisture recycling and the source-sink relations between evaporation and precipitation. However, there are several atmospheric moisture...journal article 2013

Euser, T. (author), Winsemius, H.C. (author), Hrachowitz, M. (author), Fenicia, F. (author), Uhlenbrook, S. (author), Savenije, H.H.G. (author)The use of flexible hydrological model structures for hypothesis testing requires an objective and diagnostic method to identify whether a rainfall-runoff model structure is suitable for a certain catchment. To determine if a model structure is realistic, i.e. if it captures the relevant runoff processes, both performance and consistency are...journal article 2013

Gharari, S. (author), Hrachowitz, M. (author), Fenicia, F. (author), Savenije, H.H.G. (author)Conceptual hydrological models rely on calibration for the identification of their parameters. As these models are typically designed to reflect real catchment processes, a key objective of an appropriate calibration strategy is the determination of parameter sets that reflect a “realistic” model behavior. Previous studies have shown that...journal article 2013

(author)An analytical model for tidal dynamics has been applied to the Yangtze Estuary for the first time, to describe the tidal propagation in this large and typically branched estuary with three-order branches and four outlets to the sea. This study shows that the analytical model developed for a single-channel estuary can also accurately describe the...journal article 2012
