Tsaliet
Tsaliet is a river in northern Ethiopia, belonging to the Nile basin. Rising in the mountains of Dogu’a Tembien, where it is first called May Leiba River and then Tinsehe River, it flows westward through a deep gorge, to become Tsaliet in its lower course, where it empties in Weri’i River, just upstream of the main Weri’i bridge along the road to Adwa. Characteristics It is mostly a confined river, locally meandering in its narrow alluvial plain, with an average slope gradient of 25 metres per kilometre. With its tributaries, the river has cut deep gorges. Along the middle of its course, it occupies sandy pediments in Addeha. Flash floods and flood buffering Runoff mostly happens in the form of high runoff discharge events that occur in a very short period (called flash floods). These are related to the steep topography, often little vegetation cover and intense convective rainfall. The peaks of such flash floods have often a 50 to 100 times larger discharge than the ...

Kidane Mihret River
Kidane Mihret is a river of the Nile basin. Rising in the mountains of Dogu’a Tembien in northern Ethiopia, it flows northward to empty finally in Weri’i and Tekezé River. Characteristics It is a confined bedrock river, with an average slope gradient of 102 metres per kilometre. With its tributaries, the river has cut a deep gorge. Flash floods and flood buffering Runoff mostly happens in the form of high runoff discharge events that occur in a very short period (called flash floods). These are related to the steep topography, often little vegetation cover and intense convective rainfall. The peaks of such flash floods have often a 50 to 100 times larger discharge than the preceding baseflow. The magnitude of floods in to a certain extent buffered by the presence of the large Awhi Dur forest in its catchment. Also, exclosures have been established; the dense vegetation largely contributes to enhanced infiltration, less flooding and better baseflow. Physical conservati ...

Graliwdo
Graliwdo is a river of the Nile basin. Rising in the mountains of Degua Tembien, Dogu’a Tembien in northern Ethiopia, it flows northward to empty finally in Wari River, Weri’i and Tekezé River. Characteristics It is a confined ephemeral river, locally meandering in its narrow alluvial plain, with an average slope gradient of 78 metres per kilometre. Hydrology The effects of check dams on hydrograph, runoff response have been studied in this river. An increase of hydraulic roughness by check dams and water transmission losses in deposited sediments are responsible for the delay of runoff to reach the lower part of the river channels. The reduction of peak runoff discharge was larger in the river segment with check dams and vegetation (minus 12%) than in segment without treatment (minus 5.5%). Reduction of total runoff volume was also larger in the river with check dams than in the untreated river. The implementation of check dams combined with vegetation reduced peak flo ...

Ferrey River
Ferrey is a river of the Nile basin. Rising in the mountains of Dogu’a Tembien in northern Ethiopia, it flows northward to empty finally in Weri’i and Tekezé River. Characteristics It is a confined bedrock river, with an average slope gradient of 141 metres per kilometre. Flash floods and flood buffering Runoff mostly happens in the form of high runoff discharge events that occur in a very short period (called flash floods). These are related to the steep topography, often little vegetation cover and intense convective rainfall. The peaks of such flash floods have often a 50 to 100 times larger discharge than the preceding baseflow. The magnitude of floods in this river has however been decreased due to interventions in the catchment: exclosures have been established; the dense vegetation largely contributes to enhanced infiltration, less flooding and better baseflow. Physical conservation structures such as stone bunds and check dams also intercept runoff. Irrigate ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Korowya
Korowya is a river of the Nile basin. Rising in the mountains of Dogu’a Tembien in northern Ethiopia, it flows westward to empty finally in the Weri’i and Tekezé River. Characteristics It is a meandering stream in a semi-confined alluvial plain, with an average slope gradient of 31 metres per kilometre. Flash floods and flood buffering Runoff mostly happens in the form of high runoff discharge events that occur in a very short period (called flash floods). These are related to the steep topography, often little vegetation cover and intense convective rainfall. The peaks of such flash floods have often a 50 to 100 times larger discharge than the preceding baseflow.
