In 2013, the International Association of Hydrological Sciences (IAHS) established the Measurements and Observations in the XXI Century (MOXXI) working group with the specific aim to promote the advancement of novel observational techniques toward an improved comprehension of the hydrological cycle. Since then, MOXXI has attracted a vibrant multidisciplinary and international community and has organized special sessions at international conferences (EGU, AGU, and IAHS General Assembly) and focal workshops. A recent currently free-to-view community paper in the Hydrological Sciences Journal (http://www.tandfonline.com/doi/full/10.1080/02626667.2017.1420191 ) offers a synthesis of MOXXI objectives: a proactive behavior toward observations, multidisciplinarity and contamination from other fields of science, and the use of affordable and opportunistic technologies to enrich our understanding of hydrological processes.

In December 2017, the joint MOXXI – World Meteorological Organization (WMO) HydroHub “Innovation in Hydrometry - From ideas to operation” meeting was held in Geneva at the WMO headquarters. This two-half day workshop brought together members of the science and operations communities to learn about innovative observational methodologies and to foster the uptake of such novel solutions in operational environments. On the first day, around 70 participants from all over the globe attended 28 short presentations followed by Q&A on a variety of topics, including flood gauging, monitoring networks, citizen science, and drone initiatives in hydrology. On the second day, keynote talks, expert interviews, and breakout group discussions motivated the participants to identify key challenges and needs for the uptake of new technologies into hydrological practice. According to a questionnaire administered by WMO after the event, 94% of the surveyed participants deemed both days either good or excellent. We hope that similar events will help open channels of communication and cooperation between the academia and national services for the development of adequate standards and quality management practices. More information on the meeting, including the workshop report and speakers’ presentations, can be found at https://iahs.info/Commissions--W-Groups/Working-Groups/MOXXI/Information/MOXXI-2017.do

Dear colleagues,

On behalf of the IAHS-International Commission of Remote Sensing, we announce that abstract submission for the Remote Sensing and Hydrology Symposium is now open until the end of February. The University of Córdoba hosts this edition, devoted to “Earth Observation for Integrated Water and Basin Management: New possibilities and challenges for adaptation to a changing environment”, from 8-10 May 2018 in Córdoba, Spain.

During the conference, we will discuss the state-of-the-art on this topic and current and future needs from remote sensing to provide hydrologists and other related branches of science with data and tools for research on the water cycle components, hydrological modelling, water resource management, and integrated river basin management, among others.

We encourage the international community to participate in this event and contribute to its results and success; young researchers are especially encouraged to join the discussion. All accepted abstracts will be electronically edited by Copernicus; an extended version of a limited number of works will be solicited to the authors upon acceptance of abstracts to be published in a special issue of PIAHS, the proceedings journal of IAHS. Moreover, selected works from the presentations in the conference will be invited to submit a full paper to a special issue of Hydrological Sciences Journal, the official journal of IAHS, indexed in the JCR.

Please, visit our website for further details about registration and submission of abstracts http://rshssymposiumcordoba2018.com

Different options for accommodation with special fares for the conference attendees are available; we kindly advise to book in advance from our website and technical office to avoid higher prices due to the tourist season in Córdoba.

Please, distribute this information to your colleagues and international partners. We apologize for potential cross-posting. We are looking forward to welcoming you in Córdoba in May 2018.

With our best regards,

The Organizing Committee
Prof. Dr. María J. Polo, University of Córdoba
Dr. María Pat. González-Dugo, IFAPA
Prof. Christopher Neale, University of Nebraska

In November 2017 IAHS launched the new initiative to generate the 23 unsolved problems in Hydrology that would revolutionise research in the 21st century with a YouTube video.

The generation of questions is open to everyone and will be distilled through discussion on the IAHS LinkedIn group https://www.linkedin.com/groups/13552921  We aim to finalise the questions in Spring 2018.

We already have entries over a wide range of topics with draft questions and comments. Recent contributions include:

How do droughts and floods shape hydrological risk awareness? By Panta Rhei Working group “Changes in flood risk”

How are changes in vulnerability influencing trends in flood risk? By Panta Rhei Working group “Changes in flood risk”

How to assess water scarcity by considering both water quantity and quality. By  Panta Rhei Working group “Water Scarcity”

Do flood rich-poor periods exist? By Panta Rhei Working Group “Flood Change”

There is still time to add your own draft question or add a comment to the existing discussion on the group so please join the conversation.

The annual subscription is now due for Volume 63 (2018) of Hydrological Sciences Journal. Volume 63 remains at 16 issues but we have managed to keep the annual subscription rate the same. Volume 63 will continue to publish a special series of invited opinion papers directly linked to the IAHS "Panta Rhei" initiative that will be collated in the online virtual special series. Discussions and replies on these opinion papers wll also be published.

In July 2017 we announced the continued rise in Impact Factor for HSJ. The Impact Factor is 2.222 with a 5-Year Impact Factor of 2.372 (©2017 Thomson Reuters, 2016 Journal Citation Reports®).

Following the retirement of Mike Acreman, Attilio Castellarin was confirmed as the Editor-in-Chief at the IAHS Scientific Assembly at Port Elizabeth, South Africa, with Demetris Koutsoyiannis the Outgoing Editor-in-Chief and Ross Woods as the most recent Editor and a new Editor will be appointed in due course. The number of Associate Editors has risen to 41.
