Rainfall generator for the Meuse basin; Development of a multi-site extension for the entire drainage area

A stochastic weather generator is constructed to simulate long series of precipitation and temperature for the Belgian and French Meuse basin. This weather generator is based on the principle of nearest-neighbour resampling, a method which samples daily data from a historic record with replacement such that the temporal and spatial correlations...

Effects of different management regimes on mangrove ecosystem services in Java, Indonesia

Indonesia is home to the largest area of mangrove forests in the world. Urban expansion, aquaculture farms, oil-palm plantations and timber extraction have caused an estimated decline of about 1.2 million hectares of Indonesia’s mangroves since the 1980’s, and currently only 3 million hectares remain. The major cause of mangrove conversion is...

De Voordelta; een watersysteem verandert

Het ondiepe zeegebied voor de Zeeuwse en Zuid-Hollandse eilanden - de Voordelta - wordt, in tegenstelling tot het zeegebied voor de Hollandse kust, gekenmerkt door een grillig stelsel van geulen en banken. De Voordelta is de laatste decennia sterk aan het veranderen. Belangrijkste oorzaak vormt de uitvoering van het Deltaplan: de afsluiting van...

Manual for Investigation of Hydrological Processes in Mangrove Ecosystems

A description of Mangrove ecosystems. Especially the hydrological processes in these ecosystems are described. The rapport can be used as manual for studies in these Mangrove ecosystems as the rapport gives several points of attention for these studies. Furthermore the rapport gives several hints on how to analyze the data. Next to these hints...

Neerslag, openwaterverdamping en potentieel neerslagoverschot in Nederland, frequentieverdelingen in het groeiseizoen

In this report information is given on the probability of (extreme)dry or wet periods during the growing season. It is rather difficult to define an objective parameter for the indication of what is called "dry"or "wet". In this report we have chosen precipitation RR, open water evaporation Eo and the potential precipitation surplus RR-Epot,...

Analysis of rainfall data for use in design of storm sewer systems

The paper describes a comparison of calculated storm water discharges with two kinds of rainfall data: design rainfalls developed from intensity-duration-frequency relationships or from measured rainfall data and real measured time series of rainfalls or time series generated by statistical methods. These two rainfall approaches have been...

Designing of a hydrological rainfall-runoff scale model

The application of a hydrological rainfall-runoff scale model helps to illustrate hydrological processes better than a theoretical example on a black board. For this reason a first version of physical hydrological scale model was designed and built. The goal will be to build a second version which it is possible to move to be used for practical...
