Ortiz-Suslow, D.G. (author), Haus, B.K. (author), Williams, N.J. (author), Laxague, N.J.M. (author), Reniers, A.J.H.M. (author), Graber, H.C. (author)Coastal waters are an aerodynamically unique environment that has been little explored from an air-sea interaction point of view. Consequently, most studies must assume that open ocean-derived parameterizations of the air-sea momentum flux are representative of the nearshore wind forcing. Observations made at the New River Inlet in North...journal article 2015

De Bakker, A.T.M. (author), Herbers, T.H.C. (author), Smit, P.B. (author), Tissier, M.F.S. (author), Ruessink, B.G. (author)A high-resolution dataset of three irregular wave conditions collected on a gently sloping laboratory beach is analyzed to study nonlinear energy transfers involving infragravity frequencies. This study uses bispectral analysis to identify the dominant, nonlinear interactions and estimate energy transfers to investigate energy flows within the...journal article 2015

Miller, A. (author), Jonkman, S.N. (author), Van Ledden, M. (author)Since the catastrophic flooding of New Orleans due to Hurricane Katrina in 2005, the city's hurricane protection system has been improved to provide protection against a hurricane load with a 1/100 per year exceedance frequency. This paper investigates the risk to life in post-Katrina New Orleans. In a flood risk analysis the probabilities and...journal article 2015

Diepeveen, N.F.B. (author), Jarquin-Laguna, A. (author)In this paper the results are presented of experiments to prove an innovative concept for passive torque control of variable speed wind turbines using fluid power technology. It is demonstrated that by correctly configuring the hydraulic drive train, the wind turbine rotor operates at or near maximum aerodynamic efficiency for below rated wind...journal article 2014

Yu, Q. (author), Wang, Y. (author), Gao, J. (author), Gao, S. (author), Flemming, B. (author)Traditionally, vertical circulation (induced by gravity circulation and tidal straining), tidal pumping, and resuspension are suggested as the major processes for the formation and maintenance of the estuarine turbidity maximum (ETM). Due to strong mixing, tidal pumping is considered as the dominating process in macrotidal estuaries. To analyze...journal article 2014

Guo, L. (author), Van der Wegen, M. (author), Roelvink, J.A. (author), He, Q. (author)Numerous research efforts have been devoted to understanding estuarine morphodynamics under tidal forcing. However, the impact of river discharge on estuarine morphodynamics is insufficiently examined. Inspired by the Yangtze Estuary, this work explores the morphodynamic impact of river discharge in a 560 km long tidal basin based on a 1-D model...journal article 2014

Fasihi Harandi, M. (author), Yarahmadian, S. (author), Sepehrifar, M. (author), Van Gelder, P.H.A.J.M. (author)We use the Dichotomous Markov Noise (DMN) model with constant transition rates to describe the dynamics of fluctuations in the water level as a stochastic process, which is imposed on river discharge changes. By applying this model, two different regimes are determined for the long-term behaviour of the river. Based on these regimes, we define...journal article 2014

Trung, L.H. (author), Van der Meer, J.W. (author), Verhagen, H.J. (author)Little is known about the strength of the land-side slopes of the Vietnamese sea dikes under overtopping attack. Some grass-covered slopes were tested by a wave overtopping simulator. The paper describes the simulator and presents the test results. The tested grass covers could withstand overtopping rates varying from 20 l/s to 100 l/s per meter...journal article 2014

Stecca, G. (author), Siviglia, A. (author), Blom, A. (author)Sediment of different size are transported in rivers under the action of flow. The first and still most popular sediment continuity model able to deal with mixed sediment is the so-called active layer model proposed by Hirano (1971, 1972). In this paper, we consider the one-dimensional hydromorphodynamic model given by the Saint-Venant equations...journal article 2014

Lopez Lopez, P. (author), Verkade, J.S. (author), Weerts, A.H. (author), Solomatine, D.P. (author)The present study comprises an intercomparison of different configurations of a statistical post-processor that is used to estimate predictive hydrological uncertainty. It builds on earlier work by Weerts, Winsemius and Verkade (2011; hereafter referred to as WWV2011), who used the quantile regression technique to estimate predictive...journal article 2014

Pagano, T.C. (author), Wood, A.W. (author), Ramos, M.H. (author), Cloke, H.L. (author), Pappenbreger, F. (author), Verkade, J.S. (author)Skillful and timely streamflow forecasts are critically important to water managers and emergency protection services. To provide these forecasts, hydrologists must predict the behavior of complex coupled human–natural systems using incomplete and uncertain information and imperfect models. Moreover, operational predictions often integrate...journal article 2014

Beletti, B. (author), Rinaldi, M. (author), Buijse, A.D. (author), Gurnell, A.M. (author), Mosselman, E. (author)Numerous hydromorphological assessment methods have been developed in different countries during recent decades, with notable differences in their aims, scales, and approaches. Although these methods are increasingly applied to support river management, the strengths and limitations have been insufficiently investigated. This review of 121...journal article 2014

Fasihi Harandi, M. (author), De Vries, M.J. (author)Hydraulic heritage systems, both underground and exposed, have been known to be sustainable for millennia. Persian and also Roman aqueducts are examples of such hydrosystems. Their value is often overlooked but they have undeniable advantages: they have functional interconnectedness with their surrounding society and ecology, which sometimes...journal article 2014

Jarquin Laguna, A. (author), Tsouvalas, A. (author)The importance of transient analysis in hydraulic networks has been well recognized due to abrupt changes in flow or pressure introduced by valve closures or component failures. Therefore, accurate and robust numerical models are necessary to analyse the travelling pressure waves as a result of such sudden changes. This paper presents the...journal article 2014

Het doel van het veldexperiment was om over een periode van drie jaar de temporele morfodynamiek te volgen van een rechte beekloop met een breed en ondiep dwarsprofiel. Ongeveer 8 maanden na aanleg zijn alternerende banken ontstaan. In eerste instantie...journal article 2014

Viparelli, E. (author), Blom, A. (author), Ferrer-Boix, C. (author), Kuprenas, R. (author)A one-dimensional model that is able to store the stratigraphy emplaced by a prograding delta is validated against experimental results. The laboratory experiment describes the migration of a Gilbert delta on a sloping basement into standing water, i.e., a condition in which the stratigraphy emplaced by the delta front is entirely stored in the...journal article 2014

Mechelen, J. (author), Van Meurs, G. (author), Voorendt, M.Z. (author)Multif unctionele waterkeringen beschermen niet alleen het achterland tegen overstromingen (primair), maar hebben vaak een tweede belangrijke functie (secundair). Denk aan bebouwing op of in een dijk. De secundaire functie komt voort uit de toenemende druk op de ruimtelijke ontwikkeling in en rond steden aan het water. lnteressant is het als de...journal article 2014

Van Mechelen, J. (author), Jonkman, S.N. (author), Van Meurs, G. (author), Voorendt, M.Z. (author)De ruimte langs het water is gewild; we willen er wonen en werken, en er verdedigingswerken tegen het water bouwen. Het zou praktisch zijn als we verschillende functies konden combineren. Het afstudeeronderzoek van Jeroen van Mechelen (TU Delft) helpt wellicht een handje. Hij toonde aan dat het mogelijk is om een aantoonbaar veilige...journal article 2014
