Analysis of water quality for irrigation purposes in the lower Diyala River using the IWQG software
Abstract
The Water Quality Index (WQI) simplified concept is a way of integrating complex water quality data into a single value or statement. The current work is analysis and assessment of water quality downstream of Diyala River - Iraq in August 2019 using IWQG irrigation water quality guidelines software for irrigation purposes, using the IWQI model developed in Brazil by Meireles et. the. (2010), this indicator can be reflected by soil salinity, viscosity hazards, water toxicity to plants, and diverse effects on salt-sensitive crops. Eight regions along the river were collected, and these samples were analyzed. It has six parameters which are (EC), (Ca + 2), (Mg + 2), (Na + 1), (HCO3-1), and (Cl-1). The results showed that all study sites have few restrictions for agricultural use except for the site of the old Diyala Bridge and the site of downstream al-Rustamia, as the water quality index for these two sites has moderate restrictions for agricultural use, meaning that the quality of the river water is suitable for the irrigated soil on both sides of the river even if it is clayey. Heavy texture), and soil sodium problem does not occur. The software outputs recommended using the drip irrigation method for trees and vegetables to avoid direct contact of this water with crop. The researchers also recommend the IWQG irrigation water quality guidelines software as a good and efficient tool for evaluating water quality, providing recommendations and solutions for water management, and facilitating the task of evaluating water systems for agricultural purposes.
