The World Association for Sedimentation and Erosion Research (WASER) is an independent international organization that is non- profit, non-political, non-governmental, and free of any racial, ethnic or gender prejudices. WASER fully supports WHO’s commitment to public health, science, and to serving all the people of the world without fear or favour. Working together in solidarity without any discrimination based on race, nationality or ideology is the only way to win this fight against the coronavirus. As the president of WASER, I invite you to join our voices to combat all forms of rumour, discrimination, and xenophobia related to the pandemic. The COVID-19 pandemic is inflicting major disturbance on all aspects of our lives. On behalf of the Association’s Officers and Council, I wish you and your loved ones good health and I hope that you will stay safe and protected. The Association will continue its services to the members through email, newsletters, and the WASER website (http://www.waser.cn/). I am pleased to inform you that the organization of the 15th International Symposium on River Sedimentation (15th ISRS) to be held in Florence in 2022 is proceeding as planned, and that three issues of the International Journal of Sediment Research have already been published this year despite the pandemic. At this critical time, I call on all members to follow the guidelines and advice given by the WHO on how to control the COVID-19 pandemic, to support the measures to contain the virus put forward by the country in which they live, and to provide all possible help and support to their country and the world in our fight against the coronavirus. I hope everyone is keeping well and doing what is needed to keep themselves and their family safe!

As a result, Taiyuan launched a Meanwhile, the Ministry of Ecology and comprehensive treatment project for the nine rivers Environment released a plan urging local and completed it in 2018.
