The soils which show very high shear strength in a dry state but rapidly lose their on wetting are known as collapsible soils. Such rapid and massive loss of produces severe distress leading to extensive cracking differential settlements, instability building foundations, even collapse structures built these Waste marble dust is an industrial byproduct being produced large quantities globally p...

buildings with high degree of importance such as hospitals, police stations, fire stations and other vital facilities play a crucial role in crisis and risk management of cities. therefore, special attention should be paid to design and construction of these buildings in order to maintain their performance during and after the earthquake. important buildings in iran is designed according to the...

General Comments The discussion paper offers interesting results and a welcome alternative to assessing the soil carbon stocks and changes in Alaska. The equilibrium model approach is particularly helpful since the only other alternative to addressing the question of SOC response to warming seems to be process model outputs (i.e. “ESM’s” in the paper). The map is probably an improvement over ot...

Added organic materials [1], composts and organic fertilisers are involved in building soil organic matter. They are a factor in soil property improvement, and can represent an important source of nutrients for both plants and soil organisms. Even a century ago [2], the composition of added organic materials was thought to have a direct influence on organic matter transformation. Intense work i...

[1] Soil temperature and moisture are important factors that control many ecosystem processes. However, interactions between soil thermal and hydrological processes are not adequately understood in cold regions, where the frozen soil, fire disturbance, and soil drainage play important roles in controlling interactions among these processes. These interactions were investigated with a new ecosys...
