Hydrological Basins andd Agricultural Sustainability
Te influence of mountains on metro hydrology cannot t be overstated. The region faces a fundamentamental water paradox: mott precipitation falls in thee winter, while agricultural equal in thee dry summer. The solution to this mismatch lies largely in thee mountains.
Snowpack as a Strategic Water Reserve
High mountain ranges capture winturer precipitation in the form of snow. This snowpack melts slowly during the spring and arrly summer, releasing water gradually into river systems.
