Abstract
water quality index(WQI) in a simplified concept is a way for combining the complex water quality data into a single value or single statement . The present work is a trial to evaluate and classify the water quality of Al- Husseinieh River / Karbala Governorate -Iraq for irrigation purpose, by using the model of Irrigation water quality index (IWQI) developed in Brazil by Meireles et. al. (2010), this index can be reflects soil salinity, sodicity risks, water toxicity to plants and miscellaneous impacts on sensitive salts crops. Seventy two water samples were collected from three stations :( 1-Um Al- Hammam, 2-Asalamih and 3-Bab–Baghdad) on Al- Husseinieh river from (January) until (December), 2011. These samples were analyzed for six parameters which were (EC), (Ca+2), (Mg+2), (Na+1), (HCO3-1) and (Cl-1). The results showed that the values of ( IWQI) ranged from(70.04) to( 83.63) and all stations fall within the 2nd category ‘‘low restriction’’, That means the river water quality is suited to irrigated soils with light texture . And Since the the nature of soil in irrigated lands on both sides of the river is clay loam (heavy texture) so the problem of soil sodicity may occurs. The researcher also recommends farmers to avoid grow salts sensitive plants to increase agricultural productivity in the study area.
