1. Evaluation of Modern Irrigation Techniques with Brackish Water
Sammanfattning : Modern irrigation techniques are becoming increasingly important in water-scarce countries especially in arid and semiarid regions. Higher crop production and better water use efficiency are usually achieved by drip irrigation as compared to other irrigation methods. LÄS MER
2. Microbial remediation of heavy metal ion polluted soil and water
Sammanfattning : Contamination of soil and water by heavy metal ions (HMs) is a problem all over the world.The use of biological methods alone or in combination with other techniques for treatment of such polluted sites constitutes a major challenge. LÄS MER
3. Soil compaction: effects on soil hydraulic properties and preferential water flow
Sammanfattning : Soil compaction caused by passage of agricultural machinery over the surface is an issue in many agricultural soils with a high clay content. Compaction is known to modify soil pore structure and soil hydraulic properties, but can also affect the occurrence of preferential flow. LÄS MER
4. Effect of Compactive Effort on the Behaviour of a Gypsiferous Subgrade Soil
Sammanfattning : Presented in this thesis is a study of the effect of compactive effort and long-term soaking on strength, stiffness and deformation characteristics of a gypsiferous subgrade soil from Kirkuk city.The tested soil is sandy lean clay (CL) according to the Unified Soil Classification System and A-6 (6) soil according to AASHTO soil classification system.
