"Darkness" waiting for light; A river that wants to breathe

Durood - After years of demands for the dredging of the Tirah River in Durud, the cleaning operation and increasing the flow of this river in the city limits has reached its final stages.

Ambassador Arjan - Group of Provinces: The river in the city is not just a path for water to pass. On normal days, it may be part of the urban landscape; The stream that passes by the neighborhoods and its presence has become a part of the daily life of the citizens.

But with the change of weather conditions, increase in water flow or occurrence of heavy rains, this same river can become one of the most important concerns of urban management and citizens' safety. At that time, the calm appearance of the river is no longer decisive; What is important is the capacity of the bed to pass water and the preparation of the path against high volume flows.

In Darud, the "Tire" river passes through the city; The route that has been facing the problem of not being dredged for years and its handling has been considered as one of the demands of the citizens.

Now, the dredging operation of this river in the urban area is followed with the participation of Lorestan Regional Water Company, the private sector, the municipality and the city officials, and according to the explanation of the CEO of the Regional Water Company, the main part of the desired route has been completed.

This action is carried out in a situation where the officials have pointed to weather forecasts and the possibility of El Nino phenomenon, and they consider the preparation of the river path for the safe passage of possible floods to be one of the goals of the project.

In such a situation, "dark" dredging is not only a construction operation; It is part of the effort to reduce the city's vulnerability to possible risks caused by increased water flow.

However, the issue of Durood does not end with the end of the dredging operation. The experience of urban river management shows that cleaning the bed, although it can remove some of the obstacles to the passage of water, alone does not guarantee the prevention of floods.

The condition of the upstream, the amount and intensity of rainfall, the actual capacity of the bed, the conditions of the water crossing structures and the continuous maintenance of the route also play a role in the risk level. Therefore, the importance of the recent action, along with the implementation of the project, is tied to the decision of the authorities to continue the annual dredging and the necessity of turning it into a regular and evaluable program.

The role of "Tire" river in the passage of seasonal floods

In an interview with Mehr, Aminullah Jamshidi, the head of water affairs in Durood city, announced the implementation of the dredging operation of the "Tire" river in the city limits and explained that this project is being carried out using legal capacities and various credits.

In the operation of arranging the bed of the "Tireh" river, a range from Saadi Bridge to Ezzatabad area is on the agenda; According to Jamshidi, the piece is being dredged with the selection of the contractor and under the supervision of the technical experts of the regional water company.

Referring to the role of "Tireh" river in the passage of seasonal floods, Jamshidi emphasizes that this operation is followed with priority and intensive planning due to the necessity of protecting residential areas and preparing for upcoming rains. The completed targeting is also the end of the work before the beginning of the rains of the new water year; When the state of the bed and the degree of openness of the river can become more important in the passage of the currents caused by rainfall.

6.5 km from the "Tire" route under the dredging blade

According to the head of Durood water affairs, in addition to facilitating the flow of water during rains, timely dredging can prevent the accumulation of sediments and aquatic plants and disrupt downstream facilities. Maintaining the condition of the river bed and taking care of urban facilities are also among the other functions that are listed for this operation.

According to him, a part of the operation will proceed by using the capacity of the production and infrastructure financing law and through an auction, and another part will be implemented in the form of a tender from the Planning Council's appropriations. Two separate contractors have been employed to do this.

This method of implementation shows that the provision of resources and the organization of operations are not based on a single financial and operational path and different capacities have been used to advance the project.

In projects like this, it is important to coordinate between the financing method, the selection of contractors and the implementation plan; Because the delay in each section can affect the completion time of the whole route.

Jamshidi stated that the main goal of dredging is to increase the flow of the river and to prepare for the safe passage of possible floods.

From the point of view of the water management of the city, the operation should help the river course to face fewer obstacles in the conditions of increased water flow. He also appreciated the support and follow-up of the governor and officials of Durud, and emphasized the determination of Lorestan Regional Water Company to complete the projects related to flood management and protection of water resources in the region as soon as possible.

About 500 meters of dredging of this route is left and it is expected that this section will be finished in the next four to five days.

The details announced by the CEO of Lorestan Regional Water Company make the implementation dimensions of the project clearer.

In an interview with Mehr, Alireza Kakavand says: The target area for dredging is about 6,500 meters long and extends from the entrance of the city to its exit point.

According to his explanation, about 500 meters of this route remain and it is expected that this section will be completed in the next four to five days.

In this way, the major part of the route that was intended for dredging is on the verge of completion.

"Dark" river is not a new topic for Durood. Its passing through the urban area has caused the condition of the bed and the need to deal with it to be noticed by citizens and officials in different periods.

Ruhollah Lak Aliabadi, the representative of the people of Durud and Azna in the parliament, in an interview with Mehr, has described the dredging of the river as one of the old demands of the people of Durud.

Referring to meteorological warnings about the possibility of El Nino phenomenon, he said that the issue of "dark" dredging was of particular importance due to the river passing through the middle of the city and the problems that have arisen in the past years.

According to the representatives of Durood and Azna, this operation has reached a suitable stage with the follow-up of the CEO of the regional water company, the governor's support and the cooperation of the municipality.

Lak Aliabadi has informed about the agreement made between the officials for the continuation of annual dredging

Lak Aliabadi has also informed about the agreement reached between the officials for the continuation of annual dredging; An agreement that, if turned into a specific implementation plan, can become one of the most important results of this project. Because the problem of a river that passes through an urban area is not limited to a period of construction operations, and its bed conditions change over time.

From this point of view, the old demand of the citizens has two parts: first, to deal with the situation which, according to the officials, has been faced with a lack of dredging for years; Second, prevent the same situation from returning in future years.

If current operations cannot continue without a maintenance plan, more extensive measures may be needed again over time. Therefore, the agreement on annual dredging becomes practical when the responsibilities, timing, funding method and criteria for determining the need for dredging are clear.

El Nino and worry about floods; Why is river preparation important?

One of the stated reasons for placing the dredging of the "Tire" river on the agenda was the weather warnings and forecasts about the possibility of the El Nino phenomenon.

In their statements, the regional water officials and representatives of the people of Durud and Azna have raised this issue with regard to the weather forecasts, along with the necessity of preparing the river route for the safe passage of possible floods.

Preventive preparation of waterways before possible periods of heavy rainfall is part of risk management.

In a river that passes through an urban area, any reduction in water carrying capacity can raise concerns about flow conditions in high water conditions.

Therefore, "dark" dredging can be considered as one of the preventive measures in flood management, not an independent solution that removes all risk factors. Even after the completion of the operation, monitoring the condition of the river, checking the sensitive points, paying attention to the water crossing structures and coordination between the responsible agencies will maintain their importance.

The private sector, provincial credits and the cooperation of several institutions

The implementation of the "Tire" dredging project has progressed based on the cooperation of several departments. The head of Durood water affairs announced the use of the capacity of the production and infrastructure financing law as well as the credits of the planning council and said that two separate contractors participated in the implementation of the operation.
