تأثر بعض صفات التغطية الطينية للكثبان الرملية بظروف التجوية في منطقة المصب العام " القاطع الأوسط "

Abstract

This field study was conducted to understand the physical properties of the soil covering layer as affected by repeated clay covering layer operations in the Al-massab Al- Aam area " middle section " .It was found that using good technical method at the start of covering processes and repeated covering operations with time , had positive impacts on mean weight diameter " MWD" , thickness of layer , and solidity of the covering layer soil . The covering layer in the areas in wind ward of dunes had good soil structure and solidity compared to the covering layer in the crest and the lee ward dunes . The reasons of that were because of replicated movement and compaction processes on its areas , and enough time for natural plants to grow and protect soil from water and wind erosion .
