Q-Hydrology is a Christchurch (New Zealand) based company that combines applied scientific research with consultancy services. We possess over 15 years of experience that was gained internationally and in New Zealand. International experience was gained in the Netherlands, Spain, Nepal, Burundi, Mozambique, Morocco, and Vietnam. We provide these services: technical report writing, tool and model building, hydrological modelling, water allocation modelling, operational services, water resources mapping, and data processing, analysis and support. We highly value customer satisfaction, and therefore we always aim to deliver high-quality projects to the client.

MSc. Wilco Terink

Q-Hydrology is owned by Wilco Terink (download CV). He has a Master of Science degree in Hydrology and Quantitative Water Management obtained at Wageningen University, the Netherlands. Wilco has more than 15 years of experience in hydrology, with a strong focus on the development and application of hydrological models and tools, climate change impact studies, remote sensing applications, programming, processing and analyses of large (spatial) data sets, GIS, and the development of operational hydrological services. He has experience with the use of global datasets and remote sensing data for regions where data availability is scarce. Wilco is author and co-author of several scientific publications.

Key projects

• Optimising crop allocation and rotation in an agriculture-rich, free-draining, lowland catchment, to reduce the catchment’s water footprint and leaching of nutrients, in order to create a healthy and climate-resilient catchment for the future.
• Evaluating the effects of subirrigation on the regional water balance. This project analyses the regional effects of applying subirrigation on a selected number of ‘viable’ agricultural parcels. This will support the Dutch waterboards and regional planners in their decision making. This project is part of the Dutch KLIMAP initiative. Link to technical report (in Dutch).
• The use of subirrigation to i) create ideal soil moisture conditions and ii) reduce salinity levels to optimize crop growth on an experimental farm in the Netherlands’ westernmost province Zeeland (Link to project (Dutch)). This project uses SUTRA to model the transport of water and solutes in 2D through the unsaturated and saturated zone.
• Development of a rainfall-runoff model and water allocation model for the Rakaia River (New Zealand) to understand the river’s national flow regime and the interaction with its water users (Environment Canterbury Regional Council). Link to Newsroom article.
• Development of a flow naturalisation tool (Environment Canterbury Regional Council).
• Tool to estimate water usage for unmetered water abstractions (Environment Canterbury Regional Council).
• Flood statistics for the Rangitata River, New Zealand (Environment Canterbury Regional Council).
• Assessing the impact of climate change for hydropower development in the Tamakoshi River Basin, Nepal (Statkraft).
• Hydrological analysis and modelling of the Pungwe River Basin, Mozambique (Dutch Government).
• Development of operational system to provide river flow forecasts into hydropower dams to optimise hydropower operations (INTOGENER project, European Space Agency (ESA)).
• Development of Drought Monitoring and Impact Assessment Toolbox for the Mekong River Basin in Vietnam (Netherlands Space Office (NSO) and Mekong River Commission (MRC)).
• Evaluating the impact of irrigation modernization on the water balance in the Western part of the Nile Delta in Egypt (World Bank).
