Hello, I am currently working on my undergraduate thesis, which focuses on modeling seepage through a dam. I am exploring the use of MODFLOW for this purpose, as it is widely recognized for simulating flow through porous media (based on information from the USGS website and my advisor's suggestion). However, I have been struggling to find relevant papers, case studies, or comprehensive tutorials to guide me in this specific application, which has left me feeling a bit overwhelmed. Additionally, the numerous add-ons and plugins available for MODFLOW make it challenging to understand their differences and how they might apply to my work. I would greatly appreciate any explanations, references, or resources that could help me better understand this topic. Thank you very much!
