Unformatted text preview: f c ( t − t c ) t = t p = f c ( t p − t c ) = P TCA condition #1: TCA condition #2: f c ( t ) dt = P ⋅ t p t p − t c ∫ Depending on the particular infltration capacity model chosen (Philip or GreenAmpt), the two TCA conditions (equations) can be solved explicitly for the two unknowns (time to ponding and compression time) to get an explicit expression for the actual infltration: f(t) . See supplementary TCA notes for more details… F = f ( t ) t r ∫ dt = P t p ∫ dt + f c ( t − t c ) dt t p t r ∫ Q = P − f ( t ) t r ∫ dt = P − f c ( t − t c ) dt t p t r ∫ = Pt r − F From actual infltration model, can compute cumulative infltration and/or infltration excess runo±±:...
