Title: | Evaluating a multi-level subsurface drainage system for improved drainage water quality | Contributor(s): | Hornbuckle, John (author); Christen, Evan W (author); Faulkner, Richard David (author) | Publication Date: | 2007 | DOI: | 10.1016/j.agwat.2007.01.004 | Handle Link: | https://hdl.handle.net/1959.11/4259 | Abstract: | This paper describes a multi-level drainage system, designed to improve drainage water quality. Results are presented from a field scale land reclamation experiment implemented in the Murrumbidgee Irrigation Area of New South Wales, Australia. A traditional single level drainage system and a multi-level drainage system were compared in the experiment in an irrigated field setting. The single level drainage system consisted of 1.8 m deep drains at 20 m spacing. This configuration is typical of subsurface drainage system design used in the area. The multi-level drainage system consisted of shallow closely spaced drains (3.3 m spacing at 0.75 m depth) underlain by deeper widely spaced drains (20 m spacing at 1.8 m depth). Data on drainage flows and salinity, water table regime and soil salinity were collected over a 2-year period. Comparisons of water and solute movement between the multi-level drainage system and a single level drainage system are presented. Differences in the performance of the multi-level and single level drainage systems were found in the water table regime, drain water salinity and soil salinity. | Publication Type: | Journal Article | Source of Publication: | Agricultural Water Management, 89(3), p. 208-216 | Publisher: | Elsevier BV | Place of Publication: | Netherlands | ISSN: | 1873-2283 0378-3774 |
