Abstract
The sustainable management and development of the newly reclaimed sandy solts at Bustan region is facing numerous problems. Amongst, poor 5011 physical and chemical characteristics, low son fertility, water logging and soil sallni(y in some areas, and lack of sustainabte crop rotation. Due to the expected water shortage in the next decades. water logging and the resultant s.alinlty problems appeared to be the utmost.
The aim of this study was to determine the behavior of spallal oistribulion of water table depth (WID). zones of water logging, and quality of groundwater for reuse in Irrigation, 10 approach the best sustainable management of about 50.000 (eddans (21.000 hal in Bustan 1 and 2 (8US1&2) areas.
A network of two grid systems monitored the WTD on monthly or bimonthly basis tor 18 months. Ihe first with 87 large-scale cbservation wells (LSOW) covering BUS 1 &.2 areas. and the second with 92 srnenscate observation weits (SSOW) distllbuled as 34, J 1. and 27 in three villages suffering from water logging problems. Ati tbn Abi Taleb (AlA T). Mohamed Retaat (MRFT), and Tawteek EI·Haxeem (THl<M). respectively. Water samples from the cbservation wells were collected to assess the parameters 01 water quality.
Results showed that INTO were ranged from 0.23 to 7.52 m. wnlch reneoed the existence of continuous water logging problems in some areas especially at AJAT, MRFT, and Tl-1KM villages. The spatial distributico of WTD was characterized through the geoslatistiQlI approach, and the tilted varioqrarn for temporal WTD was exponential Field maps using the Kriging technique were produced 10 explore the spatla: behavior of WTO, and to locate the areas with water 1099in9 probtems Results or the KrIging leci\nique were evaluated 10 assure their accuracy and evidenced by tow standard errors and highly Significant correlation coeffIcients
The v tater logging problem appeared In some areas of 8ustan region was mainly due (a seepage lrom irrigation canals. change (rom Ihe installed modem (sprinkler and drip) irrigation systems to surface system. lack of information 011 crop water requirements and irrigation scheduling, and insufficient drainage system. This problem reoresenls a major constraint for Ihe sustainable agricultural production at the Bustan region.
