Evaluation of Irrigation Water Quality Index (IWQI) for Habbaniya Lake in Anbar Governorate, Iraq

Abstract

A study was conducted to estimate the Irrigation Water Quality Index (IWQI) for Habbaniya Lake in central Iraq for irrigation purposes. The samples were taken at sixteen stations in October 2019. Studied samples were examined for ten Physico-chemical parameters Hydrogen Number (pH), Electrical Conductivity (EC), Temperature (T °C), Total Dissolved Solids (TDS), Total Hardness (T.H.), Turbidity (NTU), Sodium Absorption Ratio (SAR), Na+, Cl−, and HCO3 −. The results showed that 68.75% of the study water samples fall within the low restriction category (LR) irrigation water in eleven stations (which is dominant in all parts) and 25% of the search region falls under the no restriction category (NR) irrigation water in four stations (which is dominant in the northwestern part at station 5-8). Meanwhile, a small part of the study area represents 6.25% of the water samples is classified as a moderate restriction (MR) irrigation water in one station (in the central part). Accordingly, these categories are suitable to use only with the soil having low to moderate permeability with a plant of some kind for specified tolerance of moderate salts content. The IWQI is homogeneous and suitable for irrigation in all parts, especially the northwestern part which represents the entrance waters through Warar Canal that fed principally from the Euphrates River.

Applying geographic information systems (GIS) techniques to estimate surface area of Al-Razzaza Lake, Karbala province, Iraq

“…These bodies of water, whether natural or artificial, are considered one of the most important elements in maintaining balance and are used, whether natural or artificial, primarily to maintain rivers at the appropriate water level and to store river water during flood seasons for later use when the rivers are low. Studies related to lake water are important, because it is one of the water supplies for domestic use, industrial uses, and crop irrigation, as well as to support life, whether for humans, plants, or animals [1]. Attention to water quality is essential and no less important than its quantity [2].…”

Assessment of Water Quality of Al-Habbaniya Lake by Using Statistical Techniques (Cluster and Factor Analysis)

“…Numerous scholars have examined biological and environmental studies to evaluate the properties of Habbaniya lake. [10][11][12][13][14][15][16][17][18]. The present study aimed to evaluate using multivariate data analysis techniques on Habbaniyia lake water quality and its fluctuation in Chemical parameters.…”
