Mid-term Workshop of the Vietnam-Belgium Fund Project "Developing, training and transferring tools for flood mappingin the Central coastal area by ArcGIS and Hydrological Models"
Create date: 12/24/18
On December 21, 2018, Vietnam Academy for Water Resources - The project owner cooperates with the consultant team to organize the Mid-term Workshop of the Project under the Belgium-VietnameseStudy and Consultancy Fund (SCF)"Developing, training and transferring tools for flood mapping in the Central coastal area by ArcGIS and Hydrological Models"

The project is funded by the Embassy of Belgium through the Belgium-Vietnamese Study and Consultancy Fund. The project aims to research and develop a new solution that can improve the effectiveness of widespread flood control in the central coastal area based on current conditions, firstly piloting in Quang Nam – Danangregion. The project was approved from May 30, 2018, closing on March 31, 2019. At present,50% of project has been completed. In order to report project progress and results to the sponsor and governing agency, Vietnam Academy for Water Resources - the project owner cooperated with the Consultant team to organize the Mid-term Workshop to consult managers, experts, scientists for comments on the implementation process and initial results of the project.

Participants in the workshop were Mr. Cao Manh Cuong - Deputy Director General of Foreign Economic Relations Department - Ministry of Planning and Investment - Director of Belgium-Vietnamese Study and Consultancy Fund; representative of Disaster Management Authority - Ministry of Agriculture and Rural Development; representative of Irrigation Department of Quang Nam, Da Nang and Nghe An; representative of Thuy Loi University. Participants of Vietnam Academy for Water Resources are Prof. Dr. Tran Dinh Hoa - Deputy Director General of VAWR - Director of Project Management Unit; representatives of the Project Management Unit of VAWR. In addition, there are 02 consultant teams assisting VAWR to implement the Project.

On behalf of the Ministry of Planning and Investment, Mr. Cao Manh Cuong - Deputy Director General of Foreign Economic Relations Department - Ministry of Planning and Investment Director of Belgium-Vietnamese Study and Consultancy Fundaffirmed that this project is very meaningful for Vietnam, whichwas considered by the Ministry of Planning and Investment based on the current urgent requirements relating to climate change to reduce future losses caused by natural disasters. He hoped that after the project was completed, the results of the Project would not only be documented, but also carried out in the reality, supporting localities to obtain a set of tools to collect necessary information in terms of the flood peak, flooding areas, flood risks ... in order to respond timely to flash floods especially for the central coastal region.

In addition, he also hoped that if results were good, these can be applied to the Northern mountainous region - where many floods, extreme weather and climate change occur frequently, so losses of life and property can be reduced. He would like experts and scientists to contribute positive opinions to the project. He said that if the projectoutput achieves good results, the Belgian side will continue to support in the future to expand the scope of this project.

Prof. Dr. Tran Dinh Hoa- Deputy Director General of VAWR - Director of the Project Management Unit said that Vietnam is a country heavily affected by natural disasters and the impact of climate change has made this issue worse. In fact, management agencies and scientists have researched new technological solutions for forecasting and applied them in practice to minimize the impact of natural disasters and floods.

Prof. Dr. Tran Dinh Hoa said that, Vietnam has had many tools for hydrological-hydrauliccalculation in general and developing flood maps in particular so far; In the context of flood simulation and calculation, tools applied in Vietnam have solved many problems to facilitate the actual production and the operation of natural disaster prevention and control. However, existing softwares in Vietnam  still have certain shortcomings; for example, it has not been integrated into the GIS; it is not interested in flood problems on a large scale; it is not addressed inter-regional and inter-basin flooding; issues related to online warning and database extraction for directing natural disaster prevention and control are also limited.

Based on practical issues arising in the natural disasters and flood prevention in the Central region and other regions across the country, VAWRwould like to have a new set of tools along with existing tools to support the Central Steering Committee for Natural Disaster Prevention and Control and localities to respond to floods in the current climate change conditions timely and effectively. Therefore, the proposal of Vietnam Academy for Water Resources and was supported by SCF in order to develop, train and transfer the online flood warning and flood risk warning tool based on the geographic information system (GIS) to provide timely flood peak information, flooded areas and flood risks at any location and locality with an estimated time from 1h to 24h; piloting in Da Nang City and Quang Nam Province. The Project Director hoped that Ministry of Planning and Investment can allow topilot this tool in other provinces, first of all in Nghe An province.

On behalf of the Vietnam Academy for Water Resources Research, Prof. Dr. Tran Dinh Hoa - Deputy Director General - Director of the Project Management Unit would like to thank Ministry of Planning and Investment; Ministry of Agriculture and Rural Development; Disaster Management Authority; Quang Nam and Da Nang Irrigation Departmentshave cooperated closely with the consultant team to implement the project onschedule.

Then, representatives of two consultant teams reported the progress and the first project results in Quang Nam and Da Nang. At the same time, the delegates also discussed and contributed many valuable opinions to help the Project implementation on schedule with good quality and bring about practical effects.

Assoc. Dr. Nguyen Thanh Tung - Thuyloi University said that for complex models, there are experts at the central level being able to operate these models, but at localities, it is necessary to have tools which are not too complicated so that they can take the initiative in developing inundation maps, quickly responding to disasters, immediately showing the results of flooded area to make a timely response. Therefore, he said that this project has a suitable approach.

This tool helps localities assess the damage and warn risks, so it is necessary to point out flooded area in ​​each commune because after the response there is damage assessment. For algorithms, it is necessary to validate with many floods, the typical rain-causing form of the region. Besides, for a set of models running in a large river basin, how long does it take to generate a food map when the rainfall data are input? How is the computercapacity required? And what are the input data in the case of connecting with the rainfall stations. Assoc. prof. Dr. Tran Thanh Tung emphasized that these are necessary and important issues for the locality to prepare for transferring.

In addition, according to Assoc. Prof. Dr. Tran Thanh Tung,the process of inundationspreading and maintaining the inundation depth is also an important information, helping the locality to respond and prepare such as evacuation, shelter, preparation of food and water ...

Assoc. Dr. Tran Thanh Tung highly appreciated the initial research results, appropriate approach with the localities and he expected that the tool will be improved and transferred to the localauthority in order to contribute to thenatural disasters prevention and mitigation, especially flood in the central coastal provinces.

Representative of Quang Nam Irrigation Department said that in order to use project results for a long time, DEM module should be flexible and time adjustable. The project should propose tools to help the locality carry out warning and response measures before natural disasters occurs such as computer configuration, running time ... He also recommend the Consultant to point out how many rain gauge stations should be íntalled in Quang Nam, how is the density of rain gauge stations and hydro-meteorological stations and where they should be constructed; He hoped that the Consultant cancalibrate the standard parameters, update large floods in 1999, 2007, 2013, 2016, 2018 ...
