A Modified Time Domain Random Walk Approach for Simulating Colloid Behavior in Fractures: Method Development and Verification

Abstract Colloids are ubiquitous in groundwater systems, and understanding their behavior is of critical importance as they can pose a threat to human and environmental health. Extensive research has been conducted to model colloid behavior in fractures leading to the development of a number of analytical solutions, albeit for single fractures. However, the application of these analytical solutions at the network scale has not yet been …
