Rock Mechanics and Rock Engineering
Fracture initiation and propagation from a wellbore within a rock formation exhibit nonlinear and inelastic behaviors. When the rock material undergoes plastic deformation prior to failure, the classical Griffith theory is no longer valid. In this st

Halite formations are attractive geothermal reservoirs due to their high heat conductivity, resulting in higher temperatures than other formations at similar depths. However, halite formations are highly reactive with undersaturated water. An underst

The heterogeneity in the soil medium makes it economically impossible to measure the soil characteristics across the whole soil profile. Inverse modelling configures a computer model to simulate the groundwater system and calibrates it to identify th

Porosity measurement is a key factor to identify the hydraulic performance of low permeable porous materials (e.g. rock or concrete). Porosimetry tests such as Mercury Intrusion Porosimetry (MIP), Nuclear Magnetic Resonance (NMR), or Gas Expansion (G

In deep reservoirs, the formations consist of naturally or artificially fractured rocks. The fluid flow coupled with heat transfer through fractures is commonly modeled by discrete fracture approach. In this study, fluid flow and solute/heat transpor

Snow and ice accumulation induces hazardous driving conditions due to the effect of reduced friction on the road surface. A traditional chemical-based snow melting approach is not environmentally friendly and effective when the temperature is below

Nitrogen is a key agricultural input which is crucial for crop growth, development, and yield. However, an excess application of nitrogen may result in the nitrate contamination of groundwater. This research focused on the estimation of nitrate leach

Soil moisture is highly variable in space and time. Climate change is expected to increase the variation in precipitation that may cause more frequent extremes in soil moisture. This will have major impacts on agriculture and infrastructure. Hence, f

Electromagnetic induction surveys are commonly used to assess soil salinity. In this study, a DualEM 1S instrument was used to survey an area in southern Manitoba to characterize sulphate-dominated salinity in clay-rich alluvial soils. The efficacy o
