WebMay 13, 2024 · The flow in a normal vein is monophasic and has very little phasicity with normal breathing and cardiac patterns with increased reversal of flow after distal augmentation. Norma venous flow in cephalic vein. Fistula waveform. A fistula waveform is going to be high velocity, low resistance in both the artery and the vein. WebIn previous work a solution was developed for the kinematic wave overland flow equation with rainfall excess given by Philip's infiltration equation. Subsequent application of this solution to field data from small plots revealed the need for an improved model. The principal requirement is the incorporation of depression storage into the rising ...
