Abstract
The impacts of climate change on water resources management as well as the increasing severe natural disasters over the last decades have caught global attention. Reliable and accurate hydrological forecasts are essential for efficient water resources management and the mitigation of natural disasters. While the notorious nonlinear hydrological processes make accurate forecasts a very challenging task, it requires advanced techniques to build accurate forecast models and reliable management systems. One of the newest techniques for modelling complex systems is artificial intelligence (AI). AI can replicate the way humans learn and has the great capability to efficiently extract crucial information from large amounts of data to solve complex problems. The fourteen research papers published in this Special Issue contribute significantly to the uncertainty assessment of operational hydrologic forecasting under changing environmental conditions and the promotion of water resources management by using the latest advanced techniques, such as AI techniques. The fourteen contributions across four major research areas: (1) machine learning approaches to hydrologic forecasting; (2) uncertainty analysis and assessment on hydrological modelling under changing environments; (3) AI techniques for optimizing multi-objective reservoir operation; and (4) adaption strategies of extreme hydrological events for hazard mitigation. The papers published in this issue can not only advance water sciences but can also support policy makers toward more sustainable and effective water resources management.
Highlights
Natural disasters have been inclined to increase and become more severe over the last decades due to climate change
This Special Issue aims at overcoming these challenges, addressing continuing efforts undertaken to gain insights on hydrological processes, dealing with the effect of forecast uncertainty, and engaging in more efficient water management strategies in a changing environment
We notice that artificial intelligence has been satisfactorily used to enhance our knowledge, to learn hydrological processes, and to engage in more efficient water management strategies under changing environmental conditions
Summary
Natural disasters have been inclined to increase and become more severe over the last decades due to climate change. The forecast uncertainty plays an important role in reservoir operation and has been extensively studied in hydrology, there are comparatively less studies discussing the effect of forecast uncertainty on real-time reservoir operations [31,32,33,34,35,36]. This Special Issue aims at overcoming these challenges, addressing continuing efforts undertaken to gain insights on hydrological processes, dealing with the effect of forecast uncertainty, and engaging in more efficient water management strategies in a changing environment
