## Description

Suitable software for modelling groundwater flow and transport in a range of geological settings pertinent to the UK GDF programme\. The required technical features, hardware compatibility, licencing, and support necessary to meet NWS's needs\. Capability to simulate groundwater flow and transport using a • Capability to simulate groundwater flow and transport within fractured rock, including Discrete Fracture Network \(DFN\) and Equivalent Continuous Porous Media \(ECPM\) modelling\. • Capability to simulate hybrid models \(part DFN, part \(E\)CPM\)\. • Functionality for transport calculations, either as an inert tracer \(concentration field\) or through particle tracking algorithms\. • Flexible import functionality to include geological and structural information, lithological bodies/surfaces, borehole information etc\. • Gridding functionality suitable for DFN, CPM or hybrid models\. • Flexible export functionality of model output to support integration with other work streams \(e\.g\., post-closure safety\)\. • Functionality for density-driven flow due to variations in groundwater salinity \(e\.g\., through transport of a saline tracer\)\.
