The political interest in fish habitat suitability and, consequently, of fish populations has increased. The fish habitat suitability is a key factor for successful ecological restoration, for example via dam removal and implementation of fish passage. Furthermore, the fish population composition determines the ecological quality of water bodies...

This study aimed to generate accurate evapotranspiration (ETA) data for the Mountain Aquifer region using the SEBAL model in Google Earth Engine (GEE) with a resolution of 30 m. The analysis provided valuable insights into evapotranspiration's spatial and temporal dynamics and its relationship with land use characteristics. Significant spatial...

To obtain and fully use long series of high-precision observations of water balance components, it is necessary to quantify and reduce random and systematic data errors. This thesis applies and evaluates a previously developed data fusion methodology for bias-correcting and noise-filtering remote sensing observations of water balance variables...

The water balance model has been an indispensable tool for quantifying water supply and demand and regulating water resources for decades. By convention, hydrologists use in-situ measurements of river discharge for model calibration. Whereas hardly is it possible for areas suffering from data storage. Researchers have been working on methods...

Hydrological models are often used to evaluate future changes in streamflow. Despite the strong aware- ness of non-stationarity in hydrological system characteristics, model parameters are often assumed stationary and obtained through calibration on past conditions. The representation of system change in hydrological models is challenging, as a...

Calibration and model prediction is always affected by uncertainty in the forcing data, response data and structural error in the model. The storm-dependent parameters are believed to be able to capture these errors and improve model prediction. The goal of this research will be to further investigate and develop the storm-based approach and...

This report introduces the use of Genetic Programming (GP) into hydrology by describing the results of GP using conceptual hydrological models as physical representation. First the possibilities of GP are tested on synthetic data, which results in a shortlist of good working objective functions and insight in the most important GP settings. The...

The well field in Noardburgum has been closed since the year 1993, due to the salinization of the groundwater. Upconing and lateral attraction of brackish groundwater caused the salinization of the groundwater. Currently, Vitens is looking for ways to reinstate the Noardburgum well field without the risk of salinization. The Fresh Keeper is...

Conventional hydrological models use a deterministic approach. One could think of it like a black box, having an input, parameters, relations and an output. The parameters are calibrated by comparing the model output with observations of the system response (for example river runoff). When assessing the uncertainty in models the focus is often...

PWN is the drinking water supplier for the Province of North Holland in the Netherlands. They manage a deep infiltration system (DWAT) since 1990 with wells between NAP -55 and NAP -90 meters, which are used to inject water and to extract it after at least 60 days to produce drinking water. Renovation of these wells will lead to an increased...

The water quality of a 5 hectare lake system in Gardens by the Bay, Singapore is modelled. The lake system comprises two lakes, Dragonfly and Kingfisher Lake, connected by a 5 metre wide stream. Inflow is from runoff from the 50 hectare catchment and from pumping from the neighbouring Marina Bay Reservoir at a rate of 20 Ls-1, 24/7. Outflow is...
