Analytical treatments were made based on the linearized diffusion analog model. \n[1] It was clarified that parameter α obtained as a result of the analyses was an effective factor to describe the response of the operation, and α was denoted as \nα=√X=√T …（A) \nin which, \nX=w₀x/4µ₀, T=w₀²t/4µ₀ \nX:Distance represented non-dimensionally, T:time represented non-dimensionally, x:distance from the　upside end of open-channel (m), t:time from the change of discharge (sec), w₀: velocity of hydraulic　bore(m/sec), µ:equivalent to(hv)/2i, (hv): discharge per unit wise of channel, suffix 0 shows uniform flow and i:bottom slope. \nAlso, the phenomena of the response in the operations were transferred to down stream as dynamic, dynamic～kinematic and kinematic waves for α≪1, α≃1 and α≫1, respectively. \n[2] A simple and useful equation was derived as a result of solving the linearized diffusion analog model with in the effective range of X. \nX-T/√T={1.0(KQ=0.1, 0.1≦X≦10.0) 0.0(KQ=2/3, 0.1≦X≦10.0) -0.6(KQ=0.9, X≒1.0) \nin which, the folowing indexes were introduced to evaluate the conditions of response with the operation.
