3rd FLOWERED Exchange of Experience on the Field, Addis Ababa, Ethiopia, 5th July 2019

A field visit was organized on 4 July 2019 in the project study area in Ethiopia for the members of the consortium and several Ethiopian stakeholders. Three sites were visited:

1st site: View of the Rift axis (Coordinates: (UTM, m) 520329 Easting, 942031 Northing, Altitude 1843)

To the south are the Rift Plateau and the Wonji sugar plantation. South and southeast, a series of quaternary slag cones align with the Wonji Fault Belt (WFB) fault system. On the farthest view to the south is a series of NNW-SSW faults intersecting the edge of the Gedemsa caldera (not visible). In the foreground (near the view) is a pumice excavation site for many cement plants (one of these is the National Cement Factory).

This area is the northeastern part of the FLOWERED project area.

To the southwest is the Koka Reservoir built in 1960 over the Awash River at an altitude of 1590 m and a crest height of 40 m. It has a surface area of ​​180 km2, a maximum depth of 14 m and an average depth of 9 m. The reservoir serves to regulate the flow of the river, the water reservoir to irrigate the Wonji plantation and the electricity production at the Awash Melkassa hydropower plant.

2nd site: The Rift Plateau (Coordinates: (UTM, m) 492360 Easting, 915300 Northing, Altitude 1672)

This is a view of the Rift Plateau and its typical setting, flat land mainly grown for teff, corn and sorghum. To the east are the active Quaternary volcanoes Tulu Moye and Bora Bericho, aligned on the axis of the Rift. The Tulu Moye Volcanic Complex is a rhyolitic and pumice complex known for its geothermal potential, mainly used for therapeutic purposes. The region is under study for the production of geothermal energy, such as the Aluto Langano geothermal field in the southwest.

On the west side of this area are the Rift Butajira margin and the Butajira basaltic field which forms the boundary fault of the western escarpment. A series of rift scarf faults are also visible.

3rd site: Fluorine Filtering in the DOLESA Community (Coordinates: (UTM, m) 485276 Easting, 915886 Northing, Altitude 1701)

Detour at the junction of Sori (village of Tejitu, coordinate: 488213 East; 911578 North, altitude: 1687m) and 7 km crossing the Mojo-Hawassa Expressway under construction and the Sulula River on an all-weather road to get to in Bora Woreda, Sori Dolesa Zone and a water filtration plant for the community. This water treatment plant uses bone char to clean the water to safe levels and is managed by the community.
