MOXXI update

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 ( ) 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.
