| Popis: | Researchers of CSIRO Land and Water in Griffith in Australia have found a way to repeatedly reuse drainage water to grow crops. In the process the system will concentrate the salt in the water to a manageable level which can then be used or stored in an environmentally friendly manner. The process, known as sequential biological concentration, is based on a novel system for Land, based treatment of secondary treatment of effluent re-use. This research is regional suitability assessment of SBC for Murrumbidgee Irrigation area (MIA) an multiplication SBC suitability Index was developed by reclassifying and assigning suitability factors to groundwater depth, groundwater quality and soil texture data in a raster environment. In this study depth of watertable, groundwater salinity and hydraulic conductivity of soil for the MIA, are achieved by the combination of fieldwork subsequently followed by the Two-dimensional flow and using MODFLOW/MT3D model software. The groundwater depth and groundwater quality were regrouped by the groundwater depth suitability and groundwater quality suitability factors. To determine the regional SBC suitability we used SBC suitability Index. The results of Regional suitability assessment of SBC are presented. Preliminary GIS assessment in MIA shows that thousands of hectares of agriculture land can be benefit SBC technique of managing and exporting salts. |
