In every twenty days A group of engineers stated that this barrage discharges two thousand million cubic meters in every twenty days in years when the Nile is high, and two thousand and fifty million cubic meters in years when the Nile is low. The Nile is a million cubic meters, and the Nile is low, and the Nile is low. Before the construction of this barrage, they used to fill the bank of the Nile, where the barrage is now, with a solid fill and cover its surface with huge stones during winter, spending a lot of money on this, in addition to conscripting a large number of people from Giza Governorate and Beni Suef Governorate, and some people from Fayoum Governorate. When summer came and the Nile began to rise, they would refill what had eroded and guard it diligently, increasing patrols day and night. This continued until the Nile's rise was complete and the upstream canals were ready to be supplied. When it was time to discharge into the Qashisha, the Governor of Beni Suef, the Governor of Giza, a group of engineers, officials, and a large number of the Egyptian people would guard this dam. They would set up their tents along the bank and spend their days and nights ready for any emergency until the order came to break the dam. They would break it with caution and care, and all the floodwaters would be discharged into the Nile. Every year, a considerable amount of money was spent on this dam, and then they would break it and throw it into the river. This continued until they built that barrage, which saved them from all these troubles. When it was broken during the reign of Hayy, the matter of the dam returned as if it had never existed, and things went back to how they were in the river. Within a year, they broke the barrage. When they broke the barrage, things returned to how they were in the river. Within a year, they broke the barrage. When they broke the barrage, things returned to how they were in the river.
