Characterization and cost estimation of erosion in Abay basin: Case study on Meja watershed por Desalegn, B.

“…The result revealed that both sediment and nutrient concentrations were highly variable both in space and time; in which lower concentration occurred towards the end of the rainy season than at the beginning in each station. Based on the complex interaction of multiple natural and anthropogenic factors; the Ridge of Meja River was the most critical source areas for the loss of sediment and associated plant nutrients in the watershed during the rainy period. …”

Application of a quantitative method to evaluate flow regulating functions of ecosystems in the Zambezi Basin. Project report submitted to UNEP under the SADC project "Dam Synchron... por McCartney, Matthew P., Xueliang Cai, Smakhtin, Vladimir U., Nhamo, Luxon

“…Results indicate that the different ecosystems affect flows in different and complex ways. Broadly: i) floodplains decrease flood flows and increase low flows; ii) headwater wetlands increase flood flows and decrease low flows; iii) miombo forest, when covering more than 70% of the catchment, decreases flood flows and decreases low flows. …”
