Abstract Mountains are an essential source of the terrestrial component hydrological cycle, supplying high‐quality water to river networks and floodplain aquifers, especially during droughts. Traditionally, mountain hydrology has focused on shallow processes, overlooking significance deep‐seated rock formations due characterization challenges. Recent field studies have revealed that fractured can host rich aquifers despite their low permeability. Nonetheless, it is unclear how deep flows interact with overall functioning areas, they contribute long‐term budget, climate, morphology, geology jointly control them. Through numerical simulations, we gained new insights into addressing (a) proportion groundwater base flow its age distribution, (b) storage sensitivity recharge, (c) impact long term mean recharge extent groundwater‐fed surface drainage network under various morphological geological settings. We showed subsurface travel times follow a Gamma whose parameters modulated by hydraulic conductivity, topography. High strong decay depth conductivity in hilly topography lead table mimicking spatially distributed low‐intensity outflows feed dense network. In rugged catchments, contribution intensifies concentrates downstream portion as declines. These findings help assess changing climate might regimes geomorphological conditions identify sustainable uses environments.
