The simulation of groundwater flowing through aquifers and geological units is a key tool for the prediction, management, and control of water resources. WMC has a wide range of expertise in groundwater modeling, from complex large-scale regional water resource management models to site-specific tools. We are experts in the development of models using the industry standard modeling package, MODFLOW and have completed projects for clients to enhance its capabilities. Where appropriate we also construct models using other codes such as Feflow or Seep/W or simple tools such as spreadsheet models.
WMC’s approach to developing successful numerical models is based on clear definition of the conceptual model describing the key hydrogeological components and mechanisms to be simulated. The conceptual model, together with clear definition of the model’s objectives, leads to focused model development.
WMC has a team of specialist modelers who maintain a high level of expertise in the application of complex modeling tools. Through R&D projects and participation in international conferences they stay up to date with the latest advances in modeling techniques and software.
Projects that demonstrate groundwater flow modeling include:
| Title: |
North Kent Chalk Aquifer Model
|
| Location: |
North Kent, UK |
| Client: |
Environment Agency Southern Region, UK |
| Description: |
WMC has completed this major groundwater modeling project, involving conceptual and numerical modeling of the North Kent Chalk aquifer and the overlying Tertiaries. The project is largely driven by the EU Habitats Directive, and is focusing particularly on the potential effects of groundwater abstraction on the North Kent marshes. The aquifer system is complex, with only limited data available for the discharge zone. The project was completed in a number of phases including data compilation and GIS development, conceptual modeling investigative and then detailed numerical modeling with predictive scenarios exploring groundwater management options. |

| Title: |
Salar de Punta Negra Environmental Protection
|
| Location: |
Salar de Punta Negra |
| Client: |
Minera Escondida Ltda (MEL) |
| Description: |
Minera Escondida, the world’s largest copper mine, has a large demand for process water. A component of this water is abstracted from a wellfield in the Salar de Punta Negra. Groundwater drawdown in the Punta Negra wellfield has reduced discharges from natural springs which sustain the salar ecosystem. WMC produced a hydrological and geochemical risk model to assess likely long-term ecological impacts of groundwater abstraction. An artificial recharge system was designed and implemented to sustain the salar. |
