Groundwater models and geological models 

Whether the sustainability of groundwater abstraction is to be evaluated or soil contamination threatens to pollute the groundwater aquifer or wetland it is crucial to have a thorough understanding of geology and groundwater flow.

COWI uses a number of PC-based modelling tools when we clarify these conditions. The models can help us - among other - to determine catchment areas, leaching and the dispersal of chemical constituents and are therefore useful tools in our consulting services to groundwater customers.

We also use these modelling tools in connection with large construction work when the groundwater table needs lowering or when groundwater is used for cooling.

Modelling

COWI is very experienced and proficient in the construction of geological models and hydrogeological models. We use Mike Geomodel and Geoeditor for geological modelling and interpretation and we use Modflow and MikeSHE for hydrogeological modelling and the transport of chemical constituents.

COWI is also very experienced in the modelling of salt water using Femwater and COSI and the determination of infiltration and evaluation of nitrate leaching using DaisyGIS.
