Validation evaluation of some wells in Wadi Al-Mohammadi basin for agricultural exploitation

Abstract

The present examines study examined the chemical properties of the groundwater in the Wadi Al-Mohammadi basin, which is located between the cities of Ramadi and Hit in the Upper Euphrates region. The study is conducted based on the field, geomorphological and geological study of the study area. The water quality of some wells in the region was monitored during 2017, for irrigation according to the FAO Standard (FAO 1989) and their classification according to Richards (1954). The results of the laboratory analysis showed that all the well water studied exceeded the criteria for use of irrigation. Indoning, it is not recommended to use it in the Wadi Al-Mohammadi basin because it is saline water, where the values of electrical conductivity, which is a factor affecting agricultural use, ranged between 3.68-7.51dS/m-1 for wells 7 and 5, respectively, while the SAR ratio ranged between 7.20 - 183.6 for wells7and2, respectively. Wells (5,4,1), according to Richard's chart, 1954, were classified as C4-S2, medium and very high, and wells (2,6,3,7) C4-S4, C3-S3, C4- S3, C3-S1, respectively. Throvghont use, salt accumlations are fromd whic eventually lead to salinization of the soil and increase the state of the problem of desertification and conversion of agricultural land from producing to unproductive land. In the case of its use, follow the methods and accuracy Management intentions and selection of soil types as well as cultivation and selection of plants resistant to salinity and reduce the state of degradation of those soils within the valley.
