"Dear researchers and experts,

I am currently conducting a study on the transfer of contamination from landfill leachate to groundwater and its subsequent discharge at an outlet spring. In order to better understand this process and its potential impacts, I am seeking insights on the most suitable modelling method and software.

I would greatly appreciate your professional opinions and experiences regarding the selection of the best modelling approach for this specific scenario. Please consider factors such as accuracy, efficiency, applicability to landfill leachate contamination, and compatibility with groundwater and contaminant transport modelling.

If you have any firsthand experience or knowledge in this field, kindly share any relevant information or case studies that could assist in making an informed decision. Your valuable input will contribute significantly to the success of my research.

Thank you in advance for your time and expertise.

Best regards,

Sareh
