This study examines the transport of solutes in groundwater systems with variable density flow. The mathematical equation that is used to explain how groundwater moves through an aquifer is known as the groundwater flow equation and is used in hydrogeology. The auxiliary equation method is used to gain the analytical solutions to the underlying model equation. These solutions are gained in the form of hyperbolic, trigonometric, exponential, and rational function solutions. Mathematica generates two-dimensional and threedimensional graphs with suitable parameter values. The resulting solutions are also useful for researching wave interactions in several novel structures.eninfo:eu-repo/semantics/openAccessExact solutionsNon-linear wave equationUnderground water equationNew auxiliary equationArticle58N/AWOS:001186747800001Q12-s2.0-8518728720210.1016/j.rinp.2024.107444
