Abstract

During surface irrigation, some phases related to its hydraulics are produced. The monitoring of these phases allows determining dvance and recession curves. The recession phase occurs after the application of water to furrows. Hydraulically, it is the most complex phase and therefore difficult to predict in mathematical treatments. To obtain the recession phase, it is necessary to determine the time at which water advances over the soil surface to specific points, called stations, over the area and then record the time at which it disappears. Observing the passage of the recessive front through the measuring stations along the furrows as a function of time defines the recession curve. Using field data obtained by Ramsey (1976) and by the Department of Agriculture and Chemical Engineering, University of Colorado (1980), in three different farms:  Horticulture, Stieben e Benson. This work aimed to study the effect of the recession time on the infiltrated profile in surface irrigation.
