Agefet
Agefet is a river of the Nile basin. Rising in the mountains of Gheralta in northern Ethiopia, it flows westward to empty finally in 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 13 metres per kilometre. At the end of its course, it occupies a sandy pediment. 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. Physical conservation structures such as stone bunds and check dams intercept runoff. On many steep slopes, exclosures have been establishe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amblo
Amblo 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 ephemeral bedrock river, with an average slope gradient of 63 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 this river has however been decreased due to interventions in the catchment. On steep slopes, exclosures have been established; the dense vegetation largely contributes to enhanced infiltration, less flooding and better baseflow. Physical conservation ...

Ginda'i
Ginda'i (also spelled Gindae) is a reservoir located in the Kilte Awula’ilo ''woreda'' of the Tigray Region in Ethiopia. The earthen dam that holds the reservoir was built in 1998 by SAERT.

Tufa
Tufa is a variety of limestone formed when carbonate minerals precipitate out of water in unheated rivers or lakes. Geothermally heated hot springs sometimes produce similar (but less porous) carbonate deposits, which are known as travertine. Tufa is sometimes referred to as (meteogene) travertine. It should not be confused with hot spring (thermogene) travertine. Tufa, which is calcareous, should also not be confused with tuff, a porous volcanic rock with a similar etymology that is sometimes also called "tufa". Classification and features Modern and fossil tufa deposits abound with wetland plants; as such, many tufa deposits are characterised by their large macrobiological component, and are highly porous. Tufa forms either in fluvial channels or in lacustrine environments. Ford and Pedley (1996) provide a review of tufa systems worldwide. Fluvial deposits Deposits can be classified by their depositional environment (or otherwise by vegetation or petrographically). Pedle ...

Wukro is located along Genfel River, in the Misraqawi (Eastern) zone of the Tigray region on the Asmara-Addis Ababa highway (Ethiopian Highway 2). Wukro is surrounded by Kilte Awulaelo woreda. The rock-hewn churches around Wukro are the town's most distinctive landmarks. In earlier sources the area is usually referred to as Dongolo ( Ge'ez: ዶንጎሎ) before the foundation of Wukro as a modern town, after the name of the main village nearby, while the term Wukro just referred originally to the church area of Wuqro Cherqos which was situated within the land of Dongolo village. Due to the establishment of modern infrastructure, including a far-distance road, the area around Wuqro Cherqos evolved into a town by itself, thus separated from Dongolo and became an economic and administrative ce ...
