Deltares possesses a large knowledge base and various tools to carry out projects on the subject of salinisation, including numerical modelling, field measurement campaigns and scale models. These methods and tools allow us to thoroughly investigate salinisation issues and to implement innovative solutions for a robust, climate proof fresh water supply. The table below shows an overview of the methods and tools we utilise. Please note that by clicking on the column headers, the theme columns can be used to sort by your theme of interest:

| Deltares can test lock designs in the Lock Facility. It features brine storage and salt mixing tanks, as well as underground reservoirs for storage of salt- and freshwater. The Lock Facility was used to study the flow patterns around the salt screen used to selectively withdraw salt water near the new sea lock in IJmuiden. | Scale model |

| Computational Fluid Dynamics (CFD) Computational Fluid Dynamics analyses in salinisation projects are often carried out using Simcenter STAR-CCM+, a commercial CFD based simulation software. STAR-CCM+'s description of the buoyancy-term in the Navier-Stokes equations and k-epsilon turbulence models has been validated by Deltares. Other CFD softwares that are less frequently used in salinisation projects include D-HYDRO and OpenFOAM. | Computational Fluid Dynamics |

| iMOD is freely available and open source software for a wide range of ground water modelling tasks. iMOD consists of user interfaces, pre- and postprocessing software and computational cores based on USGS MODFLOW source code to support analysis of groundwater flow. | Computational Fluid Dynamics |

| Airborne Electromagnetic (AEM) geophysical methods Met deze meettechniek wordt met een actief elektromagnetisch (EM) systeem de elektrische geleidbaarheid van de ondergrond bepaald. De uitvoerig vindt plaats vanuit het vliegtuig of de helikopter. Door gebruik te maken van verschillende frequenties kan op verschillende diepten worden gemeten en een geleidbaarheidsprofiel van de bodem worden opgebouwd. Twee specifieke toepassingen zijn HEM (ontwikkeld door BGR, Duitsland) en Sky-Tem (ontwikkeld door Universiteit Aarhus, Denemarken). | Field measurements |

| Quick assessment tool to calculate the influence of salt intrusion through shipping locks on the salinity of fresh water, which can for example be used to calculate the salinity at drinking water abstraction points or the salinity of irrigation water. The Sea Lock Formulation is the successor of WANDA-Locks and the Zoutlekmodel (literally: 'salt leakage' model). Previous box-models also included SWINLOCKS. | Quick assessment tool |
