Abstract
Accelerated industrialization and overpopulation are placing tremendous pressure on the country's water supplies. Demand for surface water has risen because of insufficient groundwater. Twenty-one surface water samples were obtained during rainy and dry seasons and analyzed for different parameters such as sodium, calcium, magnesium and bicarbonate etc. Irrigation indices such as sodium adsorption ratio (SAR), permeability index (PI), sodium percentage (Na percent) have been calculated to evaluate surface water's suitability for irrigation. Some of the indices showed that the water reached the allowable limits.
