The paper presents a mathematical model for the study of the advective transport problem where gravity‐induced entry of chemicals takes place from open regions of lined boreholes and fracture‐type cavities that are deeply located in porous geological media. A characteristic feature of a gravity driven deep geological disposal concept is the presence of time‐dependent advective flow velocities in the system. It is shown that certain exact closed‐form solutions can be developed to describe the gravity‐driven transport of a contaminant into a fluid‐saturated host porous geologic medium.
