Geography
The ''tabia'' occupies a massive ridge at the southwest of Dogu’a Tembien, between the Zeyi gorge and the large amphitheatre-like valley of Mennewe, through which the main road winds from the lowlands to the Tembien highlands. The southern boundary is the Giba river. The highest peak is at the northern end of the ''tabia'' (2710 m a.s.l.) and the lowest place at the confluence of Zikuli and Giba rivers (1395 m a.s.l.). The difference in elevation is more than 1300 metres.
Geology
From the higher to the lower locations, the following geological formations are present:
* Upper basalt
* Interbedded lacustrine deposits
* Lower basalt
* Amba Aradam Formation
* Mekelle Dolerite

Climate and hydrology
Climate and meteorology
The rainfall pattern shows a very high seasonality with 70 to 80% of the annual rain falling in July and August. Mean temperature in Dengolo is 18 °C, oscillating between average daily minimum of 10 °C and maximum of 25.7 °C. In the lowland Kemishana village, at 1430 metres, the mean temperature amounts to 26.7 °C. The contrasts between day and night air temperatures are much larger than seasonal contrasts.
Rivers
The Giba River
The Giba is a river of northern Ethiopia. It starts at the confluence of Genfel and Sulluh (which rises in the mountains of Mugulat) (3,298 metres above sea level) and flows westward to the Tekezé River. Future Lake Giba will occupy the plain w ...

. This river and its tributaries have incised deep gorges which characterise the landscape.
The drainage network of the ''tabia'' is organised as follows:
* Giba River, with two tributaries (from upstream to downstream):
** Zeyi River, at the border of ''tabias'' Simret and Walta
** Gereb Awehi (Mennewe) River, in ''tabia'' Simret and Abergele (woreda)
Whereas they are (nearly) dry during most of the year, during the main rainy season, these rivers carry high runoff discharges, sometimes in the form of flash flood
A flash flood is a rapid flooding of low-lying areas: washes, rivers, dry lakes and depressions. It may be caused by heavy rain associated with a severe thunderstorm, hurricane, or tropical storm, or by meltwater from ice and snow. Flash f ...

Springs
As there are no permanent rivers, the presence of springs is of utmost importance for the local people. The main springs in the ''tabia'' are:
* May Fatewa in Addi Gumare
* May Neteba in Dagabr
* Damtekle in Blbla
* Gunfal in Drgza
* Mennewe in Mennewe
* May Liham in Hitsa
Water harvesting
In this area with rains that last only for a couple of months per year, reservoirs of different sizes allow harvesting runoff from the rainy season for further use in the dry season. Overall they suffer from siltation. Yet, they strongly contribute to greening the landscape, either through irrigation or seepage water. Main reservoirs are:
* Traditional surface water harvesting ponds, particularly in places without permanent springs, called ''rahaya''
* ''Horoyo'', household ponds, recently constructed through campaigns
Settlements
The ''tabia'' centre Dengolo holds a few administrative offices, a health post, a primary school, and some small shops. There are a few more primary schools across the ''tabia''. The main other populated places are:

. Particularly, Ras Alula was born in Mennewe, the son of Engda Eqube, a farmer of modest origins. In Alula's childhood, a group of people carrying baskets of bread to a wedding ceremony were stopped by a group of children led by the future ''Ras'', who demanded to know where they were going. "To the Castle of Ras Alula Wedi Qubi," they mockingly replied. Thereafter, his friends and the people of Mannewe nicknamed him Ras Alula. Later, he was to become one of the most famous African generals.
Religion and churches
Most inhabitants are Orthodox Christians. The following churches are located in the ''tabia'':
* Abune Aregawi in Zeyi, a monastery that holds the entrance to the Zeyi cave
* Abba Gabir in Dagabr
* St. Yohannes in Godba
* St. Gebriel in Dengolo
* Abba Zelibanos and St. Mariam Monastery in Mennewe
* Abba Selema in Drgza
* Sillasie in Elalla and Blbla

Trekking routes
A trekking route has been established in this ''tabia''. The tracks are not marked on the ground but can be followed using downloaded GPX files. Starting from Inda Maryam Qorar, trek 8 leads directly down to Zeyi church and cave and further across the Zeyi and Giba gorges; the trek route meets Zikuli river and follows it upstream back to the main road, down from Mennewe.
