Often this was not possible, so they had to make other waterworks, such as large cisterns (gwiebi), smaller close-bottom wells (bjar) or a groundwater well (spiera). In some cases they brought water from afar with an aqueduct (akwedott) or an underground tunnel (mina). Draining the sewage and storm water outside the fort was equally important in order to avoid contamination and diseases. When under siege, what was the most important thing for any fort to have? High strong walls? Surrounding ditches? Weapons and gunpowder? A lot of guards?

  • Every Life in 19Th and Early 20Th Century Malta
    MALTESE HISTORY Unit L Everyday Life and Living Standards Public Health Form 4 1 Unit L.1 – Population, Emigration and Living Standards 1. Demographic growth The population was about 100,000 in 1800, it surpassed the 250,000 mark after World War II and rose to over 300,000 by 1960. A quarter of the population lived in the harbour towns by 1921. This increase in the population caused the fast growth of harbour suburbs and the rural villages. The British were in constant need of skilled labourers for the Dockyard. From 1871 onwards, the younger generation migrated from the villages in search of employment with the Colonial Government. Employment with the British Services reached a peak in the inter-war period (1919-39) and started to decline after World War II. In the 1950s and 1960s the British started a gradual rundown of military personnel in their overseas colonies, including Malta. Before the beginning of the first rundown in 1957, the British Government still employed 27% of the Maltese work force. 2. Maltese emigration The Maltese first became attracted to emigration in the early 19th century. The first organised attempt to establish a Maltese colony of migrants in Corfu took place in 1826. Other successful colonies of Maltese migrants were established in North African and Mediterranean ports in Algiers, Tunis, Bona, Tripoli, Alexandria, Port Said, Cairo, Smyrna, Constantinople, Marseilles and Gibraltar. By 1842 there were 20,000 Maltese emigrants in Mediterranean countries (15% of the population). But most of these returned to Malta sometime or another. Emigration to Mediterranean areas declined rapidly after World War II.

  • Shrinking Sea of Galilee Has Some Hoping for a Miracle 13 November 2018, by Clothilde Mraffko
    Shrinking Sea of Galilee has some hoping for a miracle 13 November 2018, by Clothilde Mraffko Plans are being devised to resuscitate the freshwater body known to Israelis as the Kinneret and to some as Lake Tiberias. For Israel, the lake is vital, having long been the country's main source of water. Israeli newspaper Haaretz provides its water level daily on its back page. Its shrinking has been a source of deep concern. When two islands appeared recently due to falling water levels, it received widespread attention in the Israeli media. The Sea of Galilee has been shrinking for years, leading to the appearance of sandy spots at the water's edge It was not so long ago when swimmers at Ein Gev would lay out their towels in the grass at the edge of the Sea of Galilee. Today, they put up their parasols 100 metres (yards) further down, on a sandy beach that has appeared due to the shrinking of the iconic body of water. "Every time we come we feel an ache in our hearts," said Yael Lichi, 47, who has been visiting Believed by Christians to be where Jesus walked on the famous lake with her family for 15 years. water, the Sea of Galilee has been shrinking mainly due to overuse "The lake is a symbol in Israel. Whenever there is a drought, it is the first thing we talk about." In front of Lichi, wooden boats with Christian Since 2013 "we are below the low red line" beyond pilgrims aboard navigate the calm waters, among which "salinity rises, fish have difficulty surviving groups from across the world that visit.

  • Aqueduct Architecture: Moving Water to the Masses in Ancient Rome
    Curriculum Units by Fellows of the Yale-New Haven Teachers Institute 2006 Volume IV: Math in the Beauty and Realization of Architecture Aqueduct Architecture: Moving Water to the Masses in Ancient Rome Curriculum Unit 06.04.04 by Ralph Russo Introduction This unit seeks to raise awareness of basic, yet, historic principles of architecture as they apply to the provision of water to an urban center. Exploration of Roman aqueducts should serve this goal. It fits the study of classical civilizations in the ninth grade world civilizations curriculum. Moreover, it lends itself to interdisciplinary teaching, a great way for students to see things in context. Studying aqueduct architecture encourages proficiency in quantitative skills, language arts, and organizational skills. Quantitative activities such as measuring, using scale, and calculating volume facilitate developing math skills. Critical reading of primary and secondary sources, document based questions, discussion, reflective writing, descriptive writing, and persuasive writing teach and/or reinforce language arts skills. Readings and activities can also touch on the levels of organization or government necessary to design, build, and maintain an aqueduct. The unit is not a prescribed set of steps but is meant to be a framework through which objectives, strategies, activities, and resources can be added or adjusted to meet student needs, address curriculum goals, and help students to make connections between the past and contemporary issues. The inhabitants of Rome satisfied their need for water first from the Tiber River. Rome grew from a small farming community along the Tiber into the capitol city of an empire with almost one million inhabitants.
