The new functions that can be added at the soft for horizontal drainage design DrenVSubIR [articol]

Abstract

The objective of this paper is to study the possibilities for the performances betting of DrenVSubIR soft starting from the observations made up when this was tested for the conditions from experimental drainage fields from Bihor County. The DrenVSubIR soft, used for agricultural drainage design is made out three modules, the first one for determining distance between horizontal drains, with help the Ernst – David relation, the second one for verifying the possibility of using the drainage in sub irrigation and the third one for the technical and economical calculation of a hectare of equipped land. In the experimental drainage fields from Bihor County (Avram Iancu, Cefa, Sanmartin and Diosig) were verified over the years, different variations of drainage, with or without prism ballast filter associated with deep-loosening work through scarifying. Simulating the conditions from these experimental drainage fields led to the same distance between drains with the distance obtained in the experiments. This simulations allows the identification of the main defiences of DrenVSubIR soft.
