Non-Linear Time Series Analysis of Deep Groundwater Levels: An application to the Veluwe

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....

Advancing Adoption of Aquifer Thermal Energy Storage: a New Evaluation Method to Support Local Decision-Makers: Assessment of the Technical and Commercial Potential of Aquifer Thermal Energy Storage in New York State Considering the Requirements and Interests of Key Stakeholders

Aquifer Thermal Energy Storage (ATES) is a geothermal technique that is an important component in the transition towards renewable energy in the heating and cooling industry, which accounts for half of the world's energy consumption. However, the technology has not yet been implemented in many countries. The main reason is that extensive...

3D Intersection operations for voxel data represented as surfaces in GIS

This thesis focusses on the intersection 3D Boolean set operation on voxel data represented as surfaces, with other 3D surface based vector data, in GIS. The Application of this research makes the linkage with geohydrology possible: based on the vectorised GeoTOP (TNO) data the water infiltration and storage capacity of specific locations can be...

Groundwater modelling of the khettara area of Fezna-Jorf-Hannabou, Morocco

This master thesis comprehends a study on khettaras, historical subsurface drainage tunnels, in East Morocco. A numerical groundwater model was set up to simulate these systems and to get a better understanding of their behaviour. Subsequently, the model was used to simulate the effect of several scenarios: increased use of pumped wells in the...

Estimating hydraulic aquifer parameters from tide-induced groundwater fluctuations: A case study in Schouwen-Duiveland

In this report, the tidal method is used to estimate hydraulic aquifer parameters. The principle of the tidal method is to use head fluctuations in observation wells, caused by tidal motion in a sea or river, to determine regional hydrological characteristics of an aquifer system. As the wave propagates into the aquifer, the amplitude of the...

An assessment of groundwater resources in the Banke district of Nepal: Using groundwater balance approaches on case studies and seasonal groundwater table fluctuation estimates

Groundwater extraction has increased significantly in Nepal. In combination with climate change, this might lead to accelerated groundwater resource depletion. No recent research has been done in the assessment of these resources in the Banke district development area in the Terai. This study aims to assess whether the intensification of...
