EVALUATION OF SURFACE SEAL THICKNESS AND HYDRAULIC CONDUCTIVITY OF FOUR SOILS AS AFFECTED BY SAR AND IONIC STRENGTH OF THE SOIL SOLUTION | تقدير سمك القشور السطحية والتوصيل الهيدروليكي لأربعة أراضي وتأثرها بنسبة إدمصاص الصوديوم والقوة الأيونية للمحلول الأرضي | ABSTRACT: A surface seal is defined as a top layer of soil with hydraulic properties significantly lower than that of the subsurface layer. The surface seal could be a very thin layer or a diffused layer several centimeters thick. The thick |
