Groundwater flow is influenced by gravity, topography, and geology. The study investigates how topography controls groundwater circulation at different scales. Exact solutions and numerical models are used to analyze this relationship. The results show that topography is fractal, affecting groundwater flow patterns at various spatial scales. Geological factors like layering and permeability also impact groundwater flow. Layers of Quaternary deposits and decreasing permeability with depth create smaller, shallower circulation cells in the groundwater flow field.
