Member of the academic staff of the Department of Meteorological Engineering of Istanbul Technical University (ITU) Prof. Dr. Hüseyin Toros, drawing attention to the two new waves of rainy weather coming next week, said: “But of course “The accuracy of weather models increases as time increases, the margin of error is high. We need to study existing water resources as if the water in our dams has run out or will run out tomorrow.” “We need to keep working quickly to be able to use it economically.”
After the waters drained from the Sazlıdere Dam, cracked soils and tree trunks emerged. The birds were also seen looking for food in the prey, which was without water.
Taurus said: “Some of the Istanbul waters come from ISKI dams, some of them come from Melen Stream or Yeşilçay, Istranca streams. When we look at the previous months except December during the last year 2020, we see that 477 million cubic meters of water comes from outside of Istanbul. And when we look at the values in December, while it did not receive the precipitation that it should have had in December, we did receive it partially, this precipitation had a serious effect on the Istanbul dams, according to my calculations we gained 30 million cubic meters of water, water consumption decreased.
Our need for water decreases as the weather is cold or wet. This already has an effect on reducing water in dams. Also, in fact, the water saving studies that started in November were carried out in many publications. When we look at the water consumption in 2019 and 2020 in the summer period, it was high in 2020. When we look at these values in November, we see that the water consumption in November 2020 is less than the water consumption in November last year. . Here we also see that such posts are extremely effective. ”
Prof. Dr. Toros spoke about the image of the future as follows:
“We had a rain yesterday, we entered the year 2021 with rain. Of course, this has an effect, it has a positive effect on the dams. For example, the daily water consumption in Istanbul dams is 24 per thousand, when We look today, I see it’s 11 per thousand. ” We see that Istanbul or its surroundings has had a positive effect directly on the dams since the soil is saturated with water, although there is a light rain since evaporation is less in the next period.
Again, when we look at the weather forecasts, a new system will arrive Monday through Tuesday. It will have an effect. Then we see a new system coming on Friday, this system seems to leave a really nice shower according to some model results. Next week, the precipitation appears to be based on the model results. I hope we get the expected rain in January 2021. If we get the expected rain, the water level in the dams will start to rise rapidly. When we look at the changes of average annual precipitation in Istanbul over many years, 13% of the annual precipitation in January, 11 in February, 9% in March, 7 in April, 5 in May and June ‘on July 4 and 3, that is, 51 percent of the precipitation in Istanbul falls during the next 7 months.
Even in the case of almost normal rains and now that the inhabitants of Istanbul are paying attention to saving water, I guess we will go through a positive process without experiencing water shortages in Istanbul in the next period. But of course, as forecast consistency from weather models increases, the margin of error is high. We need to study the water resources we have as if the water in our dams is running out or tomorrow it will run out. We need to keep working quickly on how to use water economically in our own way.
Because even if the amount of precipitation that should fall in January has fallen twice, there is no downside to saving water that we will do, even if the water in the dams is too much. Because we are talking about a global climate change. We are talking about the water scarcity increasing even more in the next year, we are talking about the rapid warming of our world. We can reduce the negative effects by gradually adapting to this climate change on our own. ”
