Huang, Xinxing (author), Li, Yifan (author), Tian, Zhan (author), Ye, Qinghua (author), Ke, Q. (author), Fan, Dongli (author), Mao, Ganquan (author), Chen, Aifang (author), Liu, Junguo (author)Efficient and accurate streamflow predictions are important for urban water management. Data-driven models, especially neural network (NN) models can predict streamflow fast, while the results are uncertain in some complex river systems. Physically based models can reveal the underlying physics, but it is relatively slow and computationally...journal article 2021

Mulatu, C.A. (author), Crosato, A. (author), Langendoen, Eddy J. (author), Moges, Michael M. (author), McClain, M.E. (author)This work investigates the applicability of an analytical method for quick assessments of the long-term morphological effects of different dam operations on downstream river reaches with the idea to apply the method in feasibility studies to identify the least morphologic-impacting operation scenario. The Ribb River (Ethiopia) is used as a...journal article 2020

Boersema, M. (author), Vermeulen, B. (author), Torfs, P. (author), Hoitink, T. (author), Roelofs, G. (author), Van den Houten, G. (author)Her en der worden in Nederland in beken en kleine rivieren vispasseerbare kunstwerken aangelegd om vismigratie mogelijk te maken en de ecologie van het systeem te verbeteren. Een veel voorkomende vispassage is de zogenaamde vispasseerbare stortsteen-bekkenpassage, ook wel cascade vistrap genoemd. Cascade vistrappen kunnen een opstuwende werking...report 2011

Goorden, N. (author), Hakvoort, H. (author), Van der Krogt, R. (author)In opdracht van Vitens is in 2005 een koppeling ontwikkeld op basis van de modelcodes van Modflow en Sobek. Deze koppelingssoftware is getest in pilot gebied Wierden, onderdeel van het Regge-stroomgebied (Gehrels en Hakvoort, 2005). De resultaten van de test wezen uit dat de ontwikkelde software een krachtig instrumentarium is dat inzetbaar is...report 2009

Kai, C. (author)Coastal zones which are known as the interface between continents and oceans are vital and important to human beings because a majority of the world's population live in such zones (Nelson, 2007). Coastal systems are among the most dynamic and energetic environments on earth and they are continuously changing because of the dynamic interaction...report 2009

Lam, N.T. (author), Stive, M.J.F. (author), Wang, Z.B. (author), Verhagen, H.J. (author), Thuy, V.T.T. (author)Hydrodynamics and morphodynamics of a seasonally forced tidal inlet system are investigated using numerical models. The ocean forcing including tidal and wave actions and sediment transport is simulated using Delft3D model. Fluvial processes in Delft3D are taken into account as results from SOBEK RURAL model. Analysis of the numerical simulation...journal article 2008

Roelofsen, F. (author), Goorden, N. (author)Deze rapportage bevat de beschrijving van de afzonderlijke modellen en is om die reden opgebouwd uit 5 delen. Deel I beschrijft de totstandkoming van de geo(hydro)logie van de ondergrond. Daarbij wordt onderscheid gemaakt tussen Pleistoceen en Holoceen waarbij het Holoceen zowel regionaal als ook in meer detail lokaal is gemodelleerd. Het...report 2008

(author)In dit project is een koppeling ontwikkeld en getest tussen Modflow en Sobek. De ontwikkelde koppeling is een zogenaamde ‘expliciete’ koppeling. Per tijdstap worden fluxen en waterhoogten uitgewisseld tussen het grondwater- en oppervlaktewatermodel. Het gekoppelde model is toegepast op het gebied rond pompstation Wierden (Overijssel). Het...report 2005

Liu, H.L. (author), Liang, G.T. (author), Wu, S.Q. (author), Ji, Z.W. (author)Because of heavy deposition and water shortage, the Yellow River faces the risk of flooding and no-flow since the middle of 1980s. The problem could be solved only by integrated water management. However, Dutch has a long history fighting the flood and gets a lot of experiences in water management, especially river ecosystem recovered after 1993...report 2002
