WebPractical application of stream channel routing often require the specification of lateral inflows. The lateral inflow could be concentrated (tributary flow), or distributed along the channel (groundwater exfiltration or infiltration). A mass balance leads to: (∂Q/∂x) + (∂A/∂t) = qL Multiplying this equation by dQ/dA (or βV) leads to:
