On the evening of the 13th December cru of the three spillway gates of the Dicle Dam at the Tigris River in Turkish-Kurdistan has broken. Since then the water level in more than km downstream river stretch increased up to 6 meters and flooded a big area of land along the river with hundreds of affected settlements.
Fortunately nobody died, but the physical and agricultural destruction is enormous and unique for the last decades. The Dicle Dam1 has been constructed for electricity, irrigation and drinking water supply in the north of the province of Diyarbakir with a height of 75 m and a volume of Mio.
This will continue until the water level in the dam reservoir will fall 11 meters which is expected for these days.
Before the construction of the Dicle and creu upper Kralkizi Dam — also large — the Tigris had every years such a high flow rate. The people along the Tigris organized live corresponding to these natural floods which have been cut with the operation of these two dams.
Since people started to settle down in the former flooding areas of the Tigris River. As there were several hours for the warning by state authorities no people have been killed by the flood. But many thousands people spent the night outside with temperatures around zero degree. Also the city neighbourhood Dicle, a number of cafeterias in the urban area, several fisheries, more than 15 sand querries and other business facilities have been destroyed partly or completely.

It is assumed that due to poor maintenance and lack of training of the dam personal the gate of the dam spillway has burst. The day after the chamber of civil engineers IMO of Diyarbakir stated that these two aspects may have contributed mainly evacuatur this disaster.
In this framework for example the gates need to be replaced on time what is questioned. In the first days after the bursting of the gate, the risk was very high that the other two gates could experience the same and the upper Kralkizi Dam as well because the Kralkizi dam was also full and rains continued; luckily at a low level.
Because of economic reasons evacuatejr dam reservoir has not been emptied at an early stage. Probably it was supposed the rain would stop soon. Very limited information is shared.
The chamber of geology engineers JMO of Diyarbakir ecacuateur that a critical problem is that the Tigris in the upper km stretch and several large tributaries are categorized only as a creek3.
This status means that no areas of flood risk have been classified along the Tigris river which includes the urban area of Diyarbakir. If necessary flood risk plans would have been developed and corresponding measures against settlements and other constructions in the wetlands taken, thousands of people would have not been affected gravely.
In its statement on the 17th Decemberthe JMO proposed a plan how to implement a better policy.

It needs to be stated that profession organisations like JMO or IMO are not included in any planning or discussion on dam and water policies. The Mesopotamia Ecology Movement MEM critized that the current state policies aim to dominate fully nature with engineering and narrow economic approaches.
Further the MEM stated: What we need is less extractivism and more harmony with nature. In the next days we will understand better the destruction. We evacuateut that with the mentality the state will be the source for more disasters. We need no large dams, but small solutions for water supply, developed and operated by local people which lead to much less consumption. The Tigris should not be used for electricity, rather the river ecosystem needs to be renaturated.
The disaster caused by bursting of the spillway gate of the Dicle Dam shows how problematic and destructive dvacuateur dam policies of the Turkish state is organized.
It focus on maximum production of electricity and irrigation without taking into consideration peoples rights to land, livelihoods and basic services, balance and diversity of ecosystems and cultural heritage Tigris within Turkish state is source of first human settlements.
The state constructs and operates dams and related water infrastructures without any participation and transparency. If constructed it will lead to grave social, cultural, ecological and downstream impacts and consequently is one of the most cure dams worldwide.
There is still time to stop construction of the Ilisu Dam which is equivalent to highest destruction along km Tigris River and km tributaries and even in the downstream river parts until South Iraq.
