Determining the Storage Efficiency and Deficit Coefficient for Linear Distribution of Infiltration Depths

Abstract

This study used the definitions of irrigation systems evaluation parameters: application efficiency; application adequacy and application uniformity, in addition to the storage efficiency, the deficit coefficient and deep percolation losses. It was adopted the linear distribution of the infiltration depths for cases that intersects the line of the distribution infiltration depths with the depth required in the root zone. It was determined a several equations for the expression of each of the storage efficiency and deficit coefficient first: as a function of both the application adequacy and application uniformity second: as function of both the application adequacy and application efficiency third: as function of both the application adequacy and deep percolation losses. These equations lead to ease of use and recruitment of these transactions, both in the evaluation of irrigation systems or follow-up infiltration depths within the root zone leaching of a particular crop during the growing season to find a function of productivity.
