A new question for Istanbul, which smiles with the rains: Will the dams overflow?
Heavy rain on my son’s days, I was pumping occupancy to Istanbul. This future, however, has caused some dams to reach full capacity. Even when this is the case ‘flood’ relationship in relationships. ‘The owners of the ‘precaution’ for possible floods in the İS and dam pools in the beloved schools were found.
Well, while it is so important for Istanbul, is there a risk of overflowing the dams? Former State Hydraulic Works General Manager and Water Policies Association President Dursun Yıldız answered Hürriyet.com.tr’s questions.
Dursun Yildiz; He says that the type of flood can be minimized by the controlled discharge of the water in the dams whose fill rate is increasing, but “The construction points out that the highest point in the dam lake will be passed and there is a mechanism that can pass this one as well” said.
HERE ARE THE RISKY AREAS
Floods may occur from the water in the reservoir in a way that cannot be controlled somehow Yıldız, “Riva Stream due to Ömerli Dam, Şile Pot Stream due to Darlık Dam, Alibeyköy Stream due to Alibeyköy Dam, Göksu Stream due to Elmalı Dam” The risks involved.
WHEN DOES THE RISK REDUCE?
I’m talking about how it will be applied to living things in situations where water is both less and more.
Star, ‘The lakes in ‘Aşirı Lake’ are found in the amount given to the dam lakes in Istanbul. If the level continues to rise in the dam, some of this water is gradually opened from the dam gates to the lower rivers in the dam from the water discharge system somehow. This dam will not overflow in case said and continued:
— However, it is mentioned in the warning that some dams will overflow. In the dams to be built for this, there is water filling such as bottom spillway and spillway. These are taken care of by the flood from the dam lake. By draining the flood water into the dam lake within a plan and how much, it is also prevented from the shelf from the water. This is called flood routing work.
— Operations in the reservoirs are aimed at keeping the excess water supplied to the reservoir in a way that is not in danger, without losing it. The amount of water that cannot be retained is for rivers. Used water as spent water without an operational study. However, some discharged water, such as the Kazandere Dam and the dam in Istragalar, can be discharged from the river. In this case, flooding is risky.
HAS THE DAM OVERFLOW HAPPENED BEFORE?
There are periods when the average occupancy of the dams in Istanbul is higher than when they are in the open, and they are left,”However, there has never been an event such as an overflow.” said.
The current general occupancy rate of the dams in Istanbul is higher than last year’s… As of March 24, the occupancy rate is 89 percent… So how should we interpret this? Can I have a water shortage in Istanbul, including the coming summer?
Stating that the average occupancy rate was 93 percent in 2012 and 95 percent in 2015, Yıldız said, “However, it is seen that the dams to be built will be filled. With the expected rain and snowfall in the coming week, even more forecasts are made for these dams. This situation increases the flood,” he said.
According to Yıldız; At these rates, Istanbul will not experience water shortages this year.
The energy of water supply in Istanbul is high. In order to save this energy, it should be determined which dams are in the foreground. The waters from other dams are checked, they should be tried to be discharged around the river bed.

Your megacity is based on 20 million. Experts are among the people living in Istanbul, from his days of opportunity.
The existing water cannot support Yıldız, which has a population of 25-30 million in Istanbul, ”Today, a socialist right to speak understanding should be adopted in the supply of water to Istanbul. The use of treated wastewater and rainwater harvesting should be expanded as a pilot. In the smart city design, the necessary infrastructure for smart water management should already be formed before the people.” found in my opinion.
What worries me is; Today, water management is greatly affected by the changes that will be difficult due to the increasing pressure climate in production. Relationships between water management and energy, food and environment have increased. Warnings for disruptions. This leads to the possibility of social, economic and ecological balances.

Making predictions like water would write the rest of his days about it.
— Water is a living right and its supply service promotion as a public service. But it is getting harder to read this principle and spend the day constantly. The most correct policy in the direction of water is the policy to ensure a balance between the economic, ecological and social region. However, this is often unpleasant and one starts to give up on these goals.
— The influence of socio-politics and populist plans deviate from long plans. Then, they are victims of uneconomical and ecological solutions that disrupt the ecological balance. Because water is a constant and vital resource that is needed. Since it cannot be replaced with anything else, it must be provided in a clean and constant condition. This, in turn, forces the managements from planning to evacuation, to immediate nurturing, and deteriorates.
