Gereb Segen (May Gabat)
Gereb Segen is a reservoir located in the Inderta ''woreda'' of the Tigray Region in Ethiopia. The earthen dam that holds the reservoir was built in 2016 by the Tigray Water Bureau, with the main aim of providing Mekelle with water. Challenges In 2018-2019 the reservoir was unable to sustain the water needs of Mekelle * Pipe diameters are underfit * Leakage through the abutment * Sediment deposition by May Gabat river Irrigation Though the reservoir was not intended for irrigation, its seepage water is used in the downstream valley for irrigation. The lithology of the catchment is Antalo Limestone. Part of the water is lost through seepage; the positive side-effect is that this contributes to groundwater recharge, and it allows irrigation by the downstream communities. Homonymous places There is a (much smaller) reservoir with the same name, some 20 km to the southeast: Gereb Segen (Hintalo) Gereb Segen is a reservoir located in the Hintalo Wajirat ''woreda'' of the Tigra ...

May Gabat
May Gabat is a river of northern Ethiopia. Rising in the mountains of Enderta (woreda), Inderta (2233 metres above sea level), it flows westward to Giba River which empties finally in the Tekezé River. The Gereb Segen (May Gabat), Gereb Segen reservoir has been built on this river in 2016, mainly for providing Mekelle with potable water. Hydrography It is a confined river, locally meandering in its narrow alluvial plain, with a slope gradient of 15 metres per kilometre. With its tributaries, the river has cut a deep gorge. Tributaries Main tributary is Kalamino River which drains a large part of Mekelle; it joins May Gabat downstream from the Gereb Segen (May Gabat), Gereb Segen reservoir. Hydrology Hydrological characteristics The runoff footprint or annual total runoff volume is 58 million m³. Hydrograph#Terminology, Peak discharges up to 190 m³ per second occur in the second part of the rainy season (month of August) when there are strong rains and the soils are water ...

Reservoirs In Ethiopia
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley, and rely on the natural topography to provide most of the basin of the re ...

Gereb Segen (Hintalo)
Gereb Segen is a reservoir located in the Hintalo Wajirat ''woreda'' of the Tigray Region in Ethiopia. The earthen dam that holds the reservoir was built in 2000 by SAERT. Dam characteristics * Dam height: 14.86 metres * Dam crest length: 473 metres * Spillway width: 8 metres Capacity * Original capacity: 337408 m³ * Dead storage: 22400 m³ * Reservoir area: 11.7 ha In 2002, the life expectancy of the reservoir (the duration before it is filled with sediment) was estimated at 25 years. Irrigation * Designed irrigated area: 24 ha * Actual irrigated area in 2002: zero ha Environment The catchment of the reservoir is 3.53 km² large, with a perimeter of 11.66 km and a length of 5200 metres. The reservoir suffers from rapid siltation. The lithology of the catchment is Agula Shale. Part of the water that could be used for irrigation is lost through seepage; the positive side-effect is that this contributes to groundwater ...

Groundwater Recharge
Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table surface. Groundwater recharge also encompasses water moving away from the water table farther into the saturated zone. Recharge occurs both naturally (through the water cycle) and through anthropogenic processes (i.e., "artificial groundwater recharge"), where rainwater and or reclaimed water is routed to the subsurface. Processes Water is recharged naturally by rain and snow melt and to a smaller extent by surface water (rivers and lakes). Recharge may be impeded somewhat by human activities including paving, development, or logging. These activities can result in loss of topsoil resulting in reduced water infiltration, enhanced surface runoff and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Soil mechanics is a branch of soil physics and applied mechanics that describes the behavior of soils. It differs from fluid mechanics and solid mechanics in the sense that soils consist of a heterogeneous mixture of fluids (usually air and water) and particles (usually clay, silt, sand, and gravel) but soil may also contain organic solids and other matter.Mitchell, J.K., and Soga, K. (2005) Fundamentals of soil behavior, Third edition, John Wiley and Sons, Inc., .Powrie, W., Spon Press, 2004, ''Soil Mechanics – 2nd ed'' A Guide to Soil Mechanics, Bolton, Malcolm, Macmillan Press, 1979. Along with rock mechanics, soil mechanics provides the theoretical basis for analysis in geotechnical engineering, a subdiscipline of civil engineering, and engineering geology, a subdiscipline of geology. Soil mechanics is used to analyze the deformations of and flow of fluids within natural and man-made structures that are supported on or made of soil, or structures that are buried in soils.L ...

Antalo Limestone
The Antalo Limestone, also known as the Antalo Sequence, is a geological formation in Ethiopia. It is between 300 and 800 metres thick and comprises fossiliferous limestones and marls that were deposited in a reef. Marine microfossils have shown an age between 165 and 150 million years. Name and definition The Antalo Supersequence includes two main stratigraphic units: the Antalo Sequence and the Agula Group. The Antalo Sequence, or Antalo Limestone has been named after the town of Hintalo in Tigray, Ethiopia. The name of the formation was coined by geologist William Thomas Blanford, who accompanied the British Expedition to Abyssinia in 1868. At that time, Hintalo was a major town on the route of the invading British army. So far the nomenclature has not been proposed for recognition to the International Commission on Stratigraphy. Geographical extent The sedimentary succession is found in Ethiopia, in the Mekelle Outlier, in the Blue Nile gorge, in the Harrar Plateau and a ...

May Gabat Dam
May is the fifth month of the year in the Julian and Gregorian calendars and is the third of seven months to have a length of 31 days. May is a month of spring in the Northern Hemisphere, and autumn in the Southern Hemisphere. Therefore, May in the Southern Hemisphere is the seasonal equivalent of November in the Northern Hemisphere and vice versa. Late May typically marks the start of the summer vacation season in the United States ( Memorial Day) and Canada (Victoria Day) that ends on Labor Day, the first Monday of September. May (in Latin, ''Maius'') was named for the Greek goddess Maia, who was identified with the Roman era goddess of fertility, Bona Dea, whose festival was held in May. Conversely, the Roman poet Ovid provides a second etymology, in which he says that the month of May is named for the ''maiores,'' Latin for "elders," and that the following month (June) is named for the ''iuniores,'' or "young people" (''Fasti VI.88'').
