URBANIZATION, STREAM BASE FLOW, AND STREAMFLOW PERMANENCE
Urbanization processes alter runoff generation and stream base flow and therefore can shift streamflow permanence, either through shifts in streamflow intermittence or ephemeral flow. Changes to streamflow intermittence can occur with changes in groundwater recharge and discharge due urbanization processes such as infiltration of stormwater, changes to evapotranspiration, lawn irrigation, water supply pipe leakage, impervious surface cover, and infiltration of groundwater into wastewater pipes. Changes to runoff generation processes in urban areas can increase or decrease the presence of ephemeral flow in streams. Spatial and temporal changes to streamflow permanence may dramatically alter the ecological and social characteristics of headwater streams as they undergo urbanization. The effects of urbanization on stream base flow are explored across climate regions in this presentation. Particular focus is given to the effects of stormwater infiltration on urban stream base flow, with empirical, modeled, and conceptual frameworks.
