Klingen, L.M. (author)Een stormvloed op de Noordzee en 40 dijkdoorbraken. Niemand in Nederland weet of het 2 uur of 2 dagen duurt voordat het water ons huis bereikt. Deze thesis gaat over de ontwikkeling van een overstromingsmodel dat de aankomsttijd van dit water berekent.master thesis 2016

Keizer, K. (author)Additional Thesis - All around the world many species are dying out locally or entirely due to interferences in their habitats. One of the big problems for marine life is the creation of migration barriers which preclude migrating species to complete their life cycle.Fish passages are a way for migrating species to get around obstructions in a...student report 2016

Strohschein, P.M. (author)Since the 1990th Sasol, a local Non-Governmental-Organization (NGO), builds sand storage dams, to mitigate the consequences of droughts in the semi-arid county of Kitui, Kenya. Sand storage dams are dams constructed in ephemeral rivers which increase the storage capacity of the riverbeds. The water stored by sand storage dams enables local...master thesis 2016

Moors, J. (author)Small leaks in water supply networks often remain undiscovered, resulting in large amounts of lost water. Moreover, small leaks can grow larger over time and may result in pipe bursts, having negative consequences for the surroundings. An automatic leak localization method is required to decrease the search area and hence localize small leaks...master thesis 2016

Deurloo, T.J.C. (author)The climate and the urban systems are changing, leading to new challenges and opportunities in the urban environment. Adaptation to these challenges is needed, using the vulnerability assessment areas that are vulnerable can be identified. Vulnerability is the likelihood a system experiences harm and is the combination of both risks and...master thesis 2016

Collenteur, R.A. (author)The objective of this study is to improve the simulation of deep groundwater levels by time se- ries models with pre-defined impulse response functions. This is attempted by adding a conceptual non-linear root zone model to simulate the recharge series to the model and by testing the use of a separate response function for the percolation zone....master thesis 2016

De Vries, S. (author)Small blind estuaries are a common phenomenon on the coast of Nicaragua, but unfortunately not much is known on their hydrological characteristics. A blind estuary can be identified by a sandbar that temporarily closes the estuary from sea. These blind estuaries often have very diverse flora and fauna on which they play an important ecological...master thesis 2016

Yang Yue, Y. (author)This thesis presents a ComMod applications in Surabaya River basin, Indonesia. The ComMod approach was applied in parallel with the Negotiated Approach (NA). The NA is developed based on rich experiences in capacity building for IWRM, aiming to empower local communities in WRM at a high level. In this ComMod application, the NA provides a...master thesis 2016

Rikkert, S.J.H. (author)Hydrological models are used for several purposes, from reservoir management to stormflow prediction. However, their predictive power is often questionable. As most rainfall-runoff models are highly dependent on calibration, models often show deteriorated performance during the validation period. This is caused by too much focus on and trust in...master thesis 2015

Haagsma, M. (author)We showed that radar can provide valuable insight in crop development. There is a strong relationship between radar and the vegetation index NDVI, which is derived from visible and near infrared images. With radar we can fill the gaps present in visible and near infrared images due to cloud cover. It is shown that dual-polarized radars are...master thesis 2015

De Koning, D. (author)This thesis discusses the applicability of assimilation of artificial SMAP data into a quasi steady state hydrological model to improve soil moisture estimates. The model used for this research was SIMGRO and since no real SMAP data were available at the time of the research, artificial SMAP data were used. The ensemble Kalman filter was used to...master thesis 2015

De Vos, J. (author)Simulation of reservoir operations is important to investigate the effects of climate change and changes in human water demands on water availability in the future. Several reservoir simulation models exist, however it is unknown in which situations what type of model could be applied. This study tries to give an answer to the question how...master thesis 2015

Hessels, T.M. (author)Researches about the water cycle are done very often and are very effective to improve the efficiency of the water usage for a basin. Especially in water scarce areas, this type of research are wanted. Water scarcity occurs when water supply cannot meet the water demand. More than half of the world will experience physical or economic water...master thesis 2015

Votel, M. (author)Low groundwater levels could have negative consequences in urban areas, such as wooden pile degradation and accelerated land subsidence. Controlling groundwater levels by infiltration systems that recharge the groundwater could be important to prevent these problems. This research evaluates the technical effectiveness of different groundwater...master thesis 2015

Hofste, R.W. (author)Following the success of open access rainfall products based on earth observation data, similar global products are now under development for actual evapotranspiration. In this research, seven prototype evapotranspiration products based on MODIS and geostationary satellites were compared for the Nile basin. They include the special MOD16 version...master thesis 2014

Foka, E. (author)The growing agglomeration and climate change are two challenges for the urban areas, which result in the reduction of permeable surface, the increase of surface runoff and a change in the temperature and precipitation patterns. These, in addition to the uncertainty of the climate change, point towards the need for adaptive sustainable solutions....master thesis 2014

Schellingerhout, J. (author)Decision Support Systems (DSSs) that are used nowadays by water managers often predict states that do not correspond with the observed states. This is caused by changing parameters in the real systems, while the parameters used in the current DSSs are kept at a fixed level or follow a temporal pattern that does not always represents reality....master thesis 2014
