Course
The Logiya rises in the Ethiopian Highlands, then flows eastwards to join the Awash near Semera, below the Tendaho Dam.[1] It runs through flat lowland areas with mountainous boundaries in the Great Rift Valley of northeastern Ethiopia.[citation needed]
Watershed
The Logiya watershed is part of the Lower Awash River Basin (LARB). The upper part is in the North Wollo Zone of the Amhara Region. Lower down it is in the Afar Region.[2] The Logiya watershed lies to the west of the Awash River, and covers an area of 3,197.968 square kilometres (1,234.742 sq mi). Elevations range from 384 to 2,487 metres (1,260 to 8,159 ft) above sea level.[3] The average altitude is 890.6 metres (2,922 ft) above sea level. Mean annual temperature is 20.8 °C (69.4 °F) in the highest parts and 29 °C (84 °F) in the lower part.[4]
The watershed is mainly arid lowlands, and has fluctuating temperature and rainfall.[2] Ground cover includes grass steppe, shrub, tree steppe and bare soil with very sparse vegetation.[5] The watershed suffers from severe degradation of the soil and desertification. However, particularly in the upper regions during the periods of high rainfall, it may be subject to flooding.[6]
Hydrology
The main rainy season is from June to September. The dry season in from October to January and the small rainy season is from February to May. Mean annual precipitation varies from 1,600 millimetres (63 in) in the highlands to 160 millimetres (6.3 in) in the lowlands.[4]
