Water Saving Devices (WSDs) sustain demands for potable water, soften impacts on supply systems and inflict a positive effect on wastewater treatment systems. This study evaluated the effect of some WSDs in Oman. A questionnaire survey and some case studies were used. The survey results revealed that the pipe line syst …
The combination of aridity, extensive urbanization and expansion of irrigated fanning have brought about substantial wale demand increase and intensified the gap between rising water demands and limited existing water supply in the Sultanate of Oman. Creenhouse farming has hem adopted as pan of the government effects t …
A model is outlined that predicts NAPL which is held in pore wedges and as films or lenses on solid and water surfaces and contributes negligibly to NAPL advection. This is conceptually referred to as residual NAPL. Since residual NAPL is immobile, it remains in the vadose zone after all free NAPL has drained. Residual …
Improving irrigation efficiency is of great importance in conserving water resources of arid countries. The effect of a hydrophobic polymer (called Guilspare) to improve yields and water use efficiencies of okra (Adelmoschus esculentus) plants was investigated using a 3x3 Latin Square field experiment. Soils were treat …
Soil amendments are used to improve the water and nutrient holding capacity of coarse textured soils, and alleviate problems of infiltration and percolation in fine textured soils. The effects of a gel-forming absorbent copolymer and peatmoss as soil amendments, on intermittent evaporation, moisture distribution, and s …
