Nicola Calder has 17 years experience in numerical modelling of hydrogeologic, hydraulic and hydrologic systems. Working at Geofirma since 2002, Ms. Calder has focused on hydrogeologic modelling, with extensive experience conducting flow, two-phase flow and transport modelling in support of safety assessments, environmental assessments, site remediation assessments and research in two-phase flow transport mechanisms. Recently, Ms. Calder has been the lead modeller for infiltration modelling conducted to evaluate the final landfill cover design for highly toxic waste; for a calibrated flow model to support calculation of remediation costs at a superfund site; for two-phase modelling to support delta pressuring in underground natural gas storage reservoirs; and for gas flow and transport modelling to evaluate the feasibility of geologic repository for intermediate radioactive waste. Ms. Calder has also been extensively involved in detailed flow, two-phase flow and transport modelling to support safety assessments of hypothetical deep geologic repositories for high-level waste in Canada and the proposed low-level and intermediate level waste repository at the Bruce Site in Ontario. She has also been involved in contaminant transport modelling and groundwater source protection modelling in Ontario.

In addition to numerical modelling, Ms. Calder has developed software tools, including development of T2GGM, a gas generation model coupled to the two-phase flow model TOUGH2; and development of a 1D hydro-mechanical model coupled with T2GGM to simulate glaciation events in a hydrogeologic model. Ms. Calder also develops model pre- and post- processing software tools to support Geofirma’s modelling work within the mView application framework.
