The Integrated Approach to Hydrologic Modelling in Water Resources Engineering

Traditional water resources engineering has often relied on compartmentalized models that address specific aspects of the hydrological cycle. However, as we navigate through an era marked by unprecedented environmental challenges and the increasing complexity of water systems, it has become evident that a more comprehensive and integrated strategy is required.

Benefits of Integrated Hydrologic Modelling

  • Improved understanding of hydrologic systems

  • Increase operational efficiency

  • Promote interdisciplinary collaboration

  • Enhanced decision support

  • Minimize uncertainty

  • Expand your service offerings

  • Provide exceptional client support

Provide enhanced decision support to your clients via HGSRT – our real-time hydrologic forecasting service – and expand your service offerings.

Aerial view of a winding river flowing through lush green forested landscape.

Improved understanding of hydrologic systems by integrating surface water and groundwater into a unified, tightly-coupled model which supports explicit exchange of water between domains.

Use the Hydraulic Mixing Cell functionality to track the origin and fate of any “tagged” water source within the model (easily disaggregate baseflow, overland flow and direct precipitation).
