== Anthropogenic effects ==

[[Human impact on the environment|Anthropogenic]] effects to baseflow include [[forestry]], [[urbanization]], and [[agriculture]]. Forest cover has high infiltration and recharge because of tree roots. Removal of forest cover can have short term increase in mean flow and baseflow because less interception and [[evapotranspiration]].<ref name=":0" /> Urbanization includes a re-organization of surface and subsurface pathways so that water is flushed through catchments because of reduced hydraulic resistance, [[Manning's n|Manning’s n]], channels and impervious surfaces which decreases infiltration. In urban areas water is often imported from outside the watershed from deep wells and [[reservoir]]s. The pipes that transport the water often leak 20-25% to the subsurface which can actually increase baseflow. Agriculture c≈ancan lower baseflow if water diverted from stream for irrigation, or can raise baseflow if water is used from a different watershed. Pastures can increase compaction and reduce organic matter with reduces infiltration and baseflow.<ref name=":0" />
