Modeling of 137Cs and 60Co transport in calcareous soils by groundwater
The fate of transport of radionuclides is one of the most important factors to be considered for the safety assessment of repositories of radioactive wastes in porous media. Laboratory batch and column experiments were investigated to assess the transport of 137Cs and 60Co in calcareous loam and clay soils leached with groundwater (GW) using convection-dispersion equation model (CDE). Fractionation of Cs and Co in eight...

Effects of three tree species on microclimate and soil amelioration in the central rift valley of Ethiopia
The effect of Balanites aegyptiaca, Acacia tortilis and Acacia seyal on soil fertility and microclimate was studied in the central rift valley of Ethiopia. Sampling was done in randomized complete blocks at 1/3 radius, 2/3 radius and at crown edge radius from the tree base and control was maintained at an open area. All soil and microclimatic parameters observed under the canopy distances were significantly different...
