Abstract
Soil is considered one of the main factors of subsidence phenomena which
became continually happen in Baghdad (Ghazalia, Ameria, and Hay al-Amyl)
causing bad effects as shortage of drinking water, traffic jam and formation
swamps.
This thesis depends on soil study to a depth 15 meters, due to its
importance in subsidence. This done through specifying its chemical physical
properties.
Soil within Iraq climate, in case of water stopping for any reason it contract
and shrink away especially when it exposed to high pressure these factors
finally caused subsidence. In case of leakage underground water or that of
damaged water pipes this will contribute to chemical reactions which damage soil
structure and increasing solidity and liquidity of higher layers and sand washing
of lower areas of soil.
In case of stopping this leakage and dryness in the hot area will lead to
contract and shrink away the liquid soil and subsidence the upper layers. The
study reached that soil is a main factor behind this phenomenon.

Abstract
تناولت الدراسة ظاهرة هبوط سطح الأرض "التخسف" في منطقة الكرخ وتحديداً مناطق الغزالية والعامرية وحي العامل بالاعتماد على دراسة التربة وبعمق ١٥ متر اعتبارها عاملاً اساسياً في حدوث هذه الظاهرة ومن خلال تحديد خواصها الفيزياوية والكيمياوية كانت سبباً رئيسياً في حدوث هذه الظاهرة في المناطق المدروسة حيث أن هذه التربة وفي ظل مناخ العراق وفي حالة انقطاع المياه لأي سبب فانها تتقلص وتنكمش على نفسها وعند تعرضها إلى أي ضغط عالي يؤدي الى حدوث عملية الهبوط "التخسف".
