Abstract

The purpose of this research is a technical and economic evaluation of SUBSURFACE DRAINAGE system implementation in date palm orchards of Abadan with four cases of drain envelopes including local GRAVEL, standard GRAVEL, and SYNTHETIC ENVELOPEs (polypropylene 700 and POLYPROPYLENE 450). To achieve this, 16 laterals (subsurface drains) were installed in a 12 hectare area of date palm, in irrigation and drainage project of Abadan, in 2004. Four laterals equipped with envelopes were constructed. In order to determine and evaluate hydraulic resistance, water table curves and other needed parameters, pizometers were installed on and between drains at 0.25L, 0.5L and 0.75L (L is the length of lateral) and started to record parameters for the assessment of: 1- Technical and economic evaluation for application of various envelopes in SUBSURFACE DRAINAGE system, 2-Economic evaluation of the project and finally a selection of the best or other acceptable methods for the construction of SUBSURFACE DRAINAGE system in date palm orchards of Abadan.Finally, with regard to the obtained results, and according to importance, the fallowing four acceptable methods are proposed: 1) Construction of SUBSURFACE DRAINAGE system using trencher and pre-wrapped pipes with SYNTHETIC ENVELOPE pp-450 (Iran- made). 2) Construction of SUBSURFACE DRAINAGE system using trencher and pre-wrapped pipes with SYNTHETIC ENVELOPE pp-450 (made in Netherlands). 3) Construction of SUBSURFACE DRAINAGE system using trencher and pipes (made in Iran) with standard GRAVEL envelope. 4) Construction of SUBSURFACE DRAINAGE system using backhoe and pipes (Iran made) with standard GRAVEL envelope.
