Evaluation and development of drainage manageme south Qantara sharq area-Egypt

الملخص EN

Subsurface drainage methods were applied for disposing excess soil wate drainage methods, open and four covered drainage methods.

Covered methods based on decreasing vertical soil water movement to above.

The construction feature as it was appli study area for open drainage method, (OD) treatment, the four covered drainage methods follows: the first, perforated plastic hose enveloped with gravels and polyethylene textile (C second, perforated plastic hose enveloped with geo textile (CDf), the third, perforated pla enveloped with gravels (CDg) and the forth, only perforated plastic hose (CDs).

The theory o drainage method depends on decreasing vertical movement of wastewater to abov Performance evaluation of the subsurface drainage was carried out in terms of two agricultura and comparing with the applied drainage method in the region.

Chemical and Physical pro soil, irrigation and drainage water were measured during the agricultural seasons of 2015 private farm in south Qantara Sharq area at North Sinai Governorate-Egypt.

The meth evaluated taking into consideration crop-productivity, adding value costs of production unit, d of ground water level, and soil salinity.

The results showed that the increment of crops p percentage were (7-9%, 13-15%, 16-19%, 23-26% and 20-22%) for winter and summer crop CDgt, CDf, CDg and CDs comparing with the applied drainage system in the study area, resp Adding value costs of production unit were 28.8, 329.2, 91.3, 229.8 and 73.3 LE/ fad., whi water levels were 0.78, 1.18, 1.19, 1.24 and 1.21m under the same drained methods, respecti best results were achieved with the use of the drainage method CDg.
