The effect of variation of dimensions of solar reflectors on solar enhanced model pond

Waste water stabilization pond is a simple way of treating waste water but one of its limitations is that it requires large area of land to be efficient. This study employed the use of solar reflectors to improve the efficiency of waste water stabilization pond by investigating the effect of variation of solar reflectors on the physical, chemical and biological properties of the pond. To achieve this, three model ponds...

Quantifying the impact of integrated watershed management on groundwater availability in Gerduba watershed, Yabello district, Ethiopia

Integrated watershed management has a positive impact on groundwater balance. However, most parts of the study area particularly, Borana is the one which is suffering from severe rangeland degradation. Among others, heavy grazing, bush encroachment, gully expansion, topsoil fertility loss, sedimentation and less adequate water availability account for the greatest noticeable rangeland degradation phenomena. Due to...
