Effect of rainfall intensity, slope and two soil conditioners on bulk density and modulus of rupture for some IRAQI western soils under simulated rainfall condition

Abstract

This study have been conducted to know the effects of rainfall intensity, land slope and Bitumen & wheat straw addition on the changeability of soil bulk density and modulus of some soils at western Iraqi soils under simulated rainfall. Soil samples have been taken from (0-30cm) depth for four regions which are: Zangora, Mhammadi, Madheek and Heet whose erodibility classes are; high, moderate-high, moderate and low respectively. The samples air dried and sieved through 4 mm diameter sieve then situated in experimental flumes.
