Show WATER PROBLEM the year 1902 was marked by fihs ihs completion in egypt of one ot the most colossal engineering works of modem times this was the construction at assouad As near ahe island of of a gigantic dara stretching across the nile flora bank to bank and capable of holding back its and regulating its flow this huge dara was built in order to allow the water of the nile to be utilized toa to a greater extent n irrigation than had been the case before egypt Is a dry country where rata is scarce and its people are lo 10 rail back on the nile to water lands the water of the nile moreover carries a rich silt which when deposited upon fbi landt dormi a layer of extremely fertile go that not only docs the nile serve for irrigating tho land but tor fertilizing it us well As ight be naturally expected divers means have since thousands of years been employed tor enabling alie land to be watered by the nile the assouad dam is only a move in abo same direction by a system of openings made ii the dam the flow of the river can be regulated and water stored up above so that when needed this water could be made use of for the nile becs not always maintain the same level but rises during a certain period known as the flood season and subsides again reaching a comparatively ively low depth when the wa ter is plentiful a part of it instead of being allowed to waste into the sea Is stored up tor use during the low tide season large areas of daml which only received water in winter arc enabled to have water in summer while 9 tracts of waste lanil which received no water and were consequently barren have become irrigated and are thus rendered cultivable |
