Study and GIS-Based Mapping of Soil Chemical Properties in Kirkuk City, Iraq

Abstract

The study included selecting seven sites in Kirkuk city to determine the soil chemical properties characteristics. The samples were collected and analyzed laboratory for the period from November 2016 and for three months at the rate of three samples per site. The main objective is to study the chemical properties of the soil of the selected areas. Also, the GIS technique has used to predict soil maps. However, soil chemical properties have analyzed for samples. The highest measurement concentrations of chemical properties (pH, Electrical conductivity, organic material, total soluble salts, gypsum, total carbonates, nitrates, chlorides and sulphates) were (9, 1695 µS/cm, 6.488%, 847.5%, 3.57%, 6 mg/l, 1290 mg/l and 4.57 mg /l) respectively. Furthermore, Inverse Distance Weighting (IDW) interpolation technique has used to produce geotechnical maps of the study area. The soil in the study area tends to be basal According to the chemical properties measurements.

Evaluation of Acid Rain Impacts Using Geostatistical Analysis and Remotely Sensed Data in Kirkuk City, Iraq

“…Construction materials will degrade over time due to environmental factors, acid rain affects by accelerating the degradation (Yates, 1988). The spatial variance and distributions are determined by a geostatistical approach according to the spatial scale of the study area, the spatial pattern of the model, and the distance of the samples (Sulyman et al, 2020).…”
