In this article, we provide strong evidence for moisture feedback playing an important part in China’s precipitation. Due to the fact that China’s water scarcity has a huge impact on the economy and society, it is not only a problem for the country itself but could become a problem for the whole world in the near future. Most research in the...

This report focuses on the flooding problems in the Lower Moshi area, Tanzania. These floods are the result of the extremely large catchment of the Kilimanjaro region in combination with large peaks in precipitation during the short and the long rainy seasons. The river bordering the area of interest cannot handle these quantities of water which...

Currently available land and water use maps don’t meet the needs of hydrologists and water managers in many cases, particularly in developing countries. Existing maps often lack the resolution and detail required by hydrological models, and those that do meet requirements are limited in spatial coverage. The research presented in this report...

Consider an estuary which is described by two governing equations for two variables, the water level 'zeta' and the velocity 'u'. Having two governing equations (Saint-Venant, 1871) is sufficient to perform time integration. The problem statement for a finite domain contains two boundary conditions and an initial condition. However, if the...

Iquique is an important city in the northern of Chile. For the coast of Iquique a seismic gap with a return period of 111 ± 33 years is present. Since the last big event in 1877 only 20 % of the accumulated seismic slip is released. The configuration of Iquique is such that a large future earthquake and subsequent tsunami would generate a...

In order to achieve the Millennium development goals of the UN, different initiatives have been established worldwide. One of these initiatives has been developed in Matagalpa, Nicaragua. Through the program Agua para Todos – Agua para Siempre different institutions work together, the common goal being to provide safe drinking water and...

Ongoing urbanisation and the subsequent extensive use of the urban water system can lead to degradation of its surface water quality. In the Netherlands, urban water bodies often suffer from the manifestations of eutrophication due to (historically) high nutrient loadings. This research focused on the enhancement of surface water quality of semi...

Since the end of the last century, polders in the Netherlands have suffered from inundation due to heavy rainfall. Inundation occurrences in 1998 have led to large economic losses, especially in polders with a fast rainfall runoff process due to the high percentage of land occupied by greenhouses. This thesis focuses on water system assessments,...

Areas outside the primary flood defenses, here called unembanked areas have a special status in the Dutch water safety policy. Whereas, primary flood defenses have to fulfill to legal standards and a functional manager is appointed for construction, maintenance and management. For unembanked areas this situation is different; some provinces have...

This research focuses on polder-belt canal systems. More is demanded from these systems every day. Man induced changes, like increasing population density and increasing land value on one hand and climate change in the form of longer dry spells and more extreme precipitation events on the other hand are the main sources. The operation of the...

Introduction Low Impact Development (LID) is an alternative approach in managing stormwater runoff. Its main philosophy is to replicate the pre-development hydrological properties of water catchment. It seeks to first infiltrate, filter, store and retaining the surface runoff near to its source before draining it to downstream. Some of the...

The integration of forecasting and decision-making in real-time Decision-Support Systems (DSS) provides a powerful tool to operators of water resources systems for evaluating the future control of hydraulic structures. Decisions may be supported by presenting information about predicted disturbances, e.g. inflows into the water system, enabling...

Introduction and problem definition The IJsselmeer is located in the center of the Netherlands. For its relevance for the Dutch economy and society, it is often addressed as the Wet Hearth of the country. When looking into the future, the IJsselmeer is under climate threats. Wetter winters will bring more water into the system, in combination...

Scaling is a major barrier in increasing recovery of RO installations. One of the major unresolved scaling problems in RO is silica scaling. Depending on pH and temperature, the safe operation practice to prevent silica scaling is to keep silica concentration below 150 [mg/l] in the concentrate. In this study, it was investigated whether it is...

In this thesis, the concept of water budgeting is discussed. This concept is based on a comparison between water resources and financial resources. It aims to approach water resources management problems more like a treasurer would. Water resources can be distributed in such a way as to optimise the chance of achieving a desired goal. Depending...

Drinking water company Dunea Duin en Water produces drinking water from the Meuse River, which contains a variety of organic micropollutants (OMPs) from upstream activity. OMPs found in Dunea’s source are plant protection products, pharmaceuticals, hormones and endocrine disruptors and X-ray contrast media. Continues development of measuring...

Het onderzoek Het gebied ‘polder Westzaan’ is een uniek brakwatergebied in Europa en dankt zijn bijzondere flora en fauna aan het brak oppervlaktewater. Sinds de Zuiderzee in 1932 werd afgesloten en het IJsselmeer ontstond, wordt nog hoofdzakelijk zoet water in het gebied ingelaten. Het gaat om een gebied van circa 900 ha in de natuurgebieden...

Membrane fouling problem is one of the most crucial issues which restricts the development of MBR and is, therefore, the prime research topic for many researchers worldwide. Anaerobic MBRs offer interesting perspectives as a potential solution for the treatment of wastewaters under extreme conditions, e.g. high temperature and/or high salt...
