Some Brief Musings on Hydrologic Science in the First Half of the 21st Century

摘要

There never is a shortage of ideas on science questions and data needs in hydrology and water resources. Many have thought deeply about this issue, and some insightful commentaries recently were published in a special section of Water Resources Research (WRR) on the 50th anniversary of WRR (2015). The International Association of Hydrological Sciences, through their "Panta Rhei-Everything Flows" initiative, is leading a conversation on 23 unsolved problems in hydrology that could revolutionize research in the 21st century-questions that must relate to observed phenomena, are universal and can be solved. I will borrow from these collections and others as I put forward a few ideas.
