Abstract

This study employs an AI-based approach using a non-negative matrix factorization tool, a kind of topic modeling method, to identify key research areas in hydrology. The observed hot topics were categorized into two main topic strands through a rigorous validity analysis which are “river basin” and “soil moisture.” Focusing on studies from January 1, 2022, to December 31, 2023, it examines the interconnected topics of "river basin" and "soil moisture," narrowed down to 130 by expert review. These research items have been rigorously detailed in a tabular form for clarity and comprehensive understanding. Key findings indicate that 67 % of studies focus on “river basin,” 47 % on “soil moisture,” and 14 % on both, with “climate change” being a primary focus across these topics. The review highlights the increasing use of software, AI, and machine learning in hydrology, driven by digitalization. Optimization and forecasting are identified as prominent research areas, reflecting the ongoing relevance of climate crisis and water resource management in contemporary research.

期刊介绍： Physics and Chemistry of the Earth is an international interdisciplinary journal for the rapid publication of collections of refereed communications in separate thematic issues, either stemming from scientific meetings, or, especially compiled for the occasion. There is no restriction on the length of articles published in the journal. Physics and Chemistry of the Earth incorporates the separate Parts A, B and C which existed until the end of 2001. Please note: the Editors are unable to consider submissions that are not invited or linked to a thematic issue. Please do not submit unsolicited papers. The journal covers the following subject areas: -Solid Earth and Geodesy: (geology, geochemistry, tectonophysics, seismology, volcanology, palaeomagnetism and rock magnetism, electromagnetism and potential fields, marine and environmental geosciences as well as geodesy). -Hydrology, Oceans and Atmosphere: (hydrology and water resources research, engineering and management, oceanography and oceanic chemistry, shelf, sea, lake and river sciences, meteorology and atmospheric sciences incl. chemistry as well as climatology and glaciology). -Solar-Terrestrial and Planetary Science: (solar, heliospheric and solar-planetary sciences, geology, geophysics and atmospheric sciences of planets, satellites and small bodies as well as cosmochemistry and exobiology).
