How did the Romans build aqueducts?

Most Roman aqueducts were underground, 0.5 metres to 1 metre below ground. They were flat-bottomed, arch-section conduits with regular accesses to them. Conduits above ground were usually slab-topped. Initially they were made of stone brick. Later concrete, which was waterproof, was used. Water was moved by gravity and therefore the aqueducts had to have a gradient. A low gradient was used to prevent damage. The conduits could be supported by bridgework when valley has to be crossed or when they were needed to maintain the gradient. They had arches built in stone, brick or cement. When deep valleys had to be crossed the bridges had two or three piers of arches. Then a valley or a depression was too deep or long siphons were used instead. The conduit ended in a tank which fed the water into pipes which run to the lower level of the valley, were supported by a low bridge and ended in a tank lower down which passed the water on to another conduit. This system maintained the desired gradient. The pipes were made of led or, less often, stone or ceramic and sealed with led. They were sometimes reinforced by concrete cases or stone sleeves. The siphons could be vulnerable blockages of blow-out at the lower level where the water pressure was greater and needed careful maintenance. Maintenance was also needed to repair cracks, clear gravel and debris and remove lime scale in areas with hard water which narrowed the passage of water. The greatest example multi-pier bridge the Pont du Gard, which is part of the aqueduct which supplied Nimes, in southern France. It hasthree tiers of recessed arches with the main piers in line one above the other. The first two tiers have very high and wide arches and a third tier has low and narrow arches. It was built to carry an aqueduct to Nimes in southern France. It reaches a height of 48.8 metres (160 feet). The lower tier is 142 metres (466 feet) long and has six aches with a height of 22metres (72 ft.). The second tier is 242 metres (794 ft.) long and has eleven arches 20 metres (66 ft.) high. The upper tier is 275 metre (902 ft.) long. It originally had 47 arches (only 35 have survived) 7 metres (23 ft.) high. The width of the first pier is 6 metres (20th.), that of the second pier is 4 metres (13 ft.) and that of the third pier is 3 metres (23 ft).


Why did so many men die on the Western Front?

*For most of the war the two sides were very evenly matched. *The development of themachine gun (combined with poor tactics)turned every battle into a massacre. *Both sides had industrial economies that matched one another and could keep up with one another in terms of output, and so on. *The generals on both sides were extremely stupid, verging on the feeble-minded. They relied again and again on 'more of the same' - more men, more machine guns, more shelling. When one side invented something new - the tank - and worked out how to use it properly, it won quickly and easily! Joncey


What will happen to a woman if she disguised as a man back in the old days?

Unless she were a member of Royalty and there were (largely symbolic like Betty Grable on a tank in modern times) Battle Queens in those days, any would-be Girl Knight would be in plenty of hot (including hot holy) water! The olower her status insociety the rougher the punitive tract, though chivalry inspired a high respect for ladies who would be usually of the Noble class- fit for Knights, and barons and higher ups to take up as wives, etc. One interesting thing polygamy was rare inthe dark Ages though the moslems espoused it. (Four Queens!) Among the nobillity , LADIES DID TAKE PART in campaigns and affairs of state and there were modified maritla get-up for them, if they were of the nobility to begin with.. Joan Of arc was (Damed) after the battle of Rheims so she couldn"t easily lose her stripes , or rather fleurs de lis, but women doingmen"s jobs was generally a punishable offense and one would assume especially peasants and low-lifers, not doen under penalty. The baroness say, De Bayonne could don armor and ride with the troops, but plain Jane from Green acres fields- forget about it! There is some evidence that unlike cross-dressing-always a taboo, there were Female Spies inthe middle ages some would abuse their protective status, being totally off-base and possibly a capital crime to kill a womanin the field. Oh, (fictional) I am Lady Tatiiana of Moscow- I bear diplomatic papers- any roght swtufdf and a w3ar could break out if a female messenger (called Pages, some may have had armor- and diamond device signifying Female gender- were roughed up by the Male gentry, especially Palace guards and staff. women were at least by Christians treated with high esteem and respect.-but any low life Jane donning the equialnet of levis, no way! the higher ups have more latittude, as in any society- Noblesse Oblige! In Both senses, not merely the Rockefeller-Bilko.
