Assessing sediment enrichment ratio in Mai-Negus catchment, northern Ethiopia

Clay enrichment ratio in sediment from a small agricultural watershed in iran

Temporal variation of suspended sediment transport in the Koga catchment, North Western Ethiopia and environmental implications

Cop Abstract: Event sediment transport and yield were studied for 45 events in the upstream part of the 260 km agricultural Koga catchment that drains to an irrigation reservoir. Discharge and turbidity data were collected over a period of more than a year, accompanied by grab sampling. Turbidity was very well correlated with the sediment concentrations from the samples (r = 0.99), which allowe...

Predication of sediment delivery ratio in a small agricultural watershed

Child malnutrition in Tigray, northern Ethiopia.

OBJECTIVE Estimate levels of and identify factors contributing to child malnutrition in Tigray, Northern Ethiopia. DESIGN Cross-sectional survey. SETTING Rural communities from four zones of Tigray. SUBJECTS Three hundred and eighteen under five children representing 587 randomly selected households were included. RESULTS Among the children surveyed, 46.9%, 33.0% and 11.6% were stunted,...

Sediment delivery to the three gorges: 1. Catchment controls

The paper examines sediment yield and its response to catchment disturbance and environmental variables in the Upper Ž . Yangtze basin, where the attention of environmentalists has been drawn to the Three Gorges Project TGP . Information about the source and conveyance of sediment from the catchment area to the Three Gorges Reservoir has implications for management strategies. Methodologies for...
