Special Issue Information

Dear Colleagues,

Complex hydrological systems are characterized by processes and events whose dynamics depend on various direct and indirect factors. It has been argued that large-scale hydrological data sets may include substantially more information than hydrologists have been able to translate into theory or process-based models. Due to the enormous advances in computational power, machine-learning algorithms have recently undergone substantial advancements in handling and processing complex and big data, which has sparked a surge in machine learning applications across all domains of hydrology.

In this Special Issue, we invite researchers to contribute papers on the application of machine-learning methods together with big data to address critical issues in hydrology. The final results should either enhance our understanding of fundamental hydrological processes or provide a novel perspective on the current trends and future challenges in applying machine learning techniques to hydrology. We encourage papers on combining physics-based modelling of hydrological systems and machine learning. In addition, we welcome authors to disclose any data and code specific to their analyses that can be distributed legally. Review papers will also be considered.

Potential topics for this Special Issue may include, but are not limited to, the following:

  • Integrating scientific knowledge with machine learning for hydrological systems;
  • Improving interpretability in machine learning approaches;
  • Uncertainty quantification, propagation, and characterization in model networks;
  • Developing benchmark data sets for machine learning applications in hydrology;
  • Assembling multiple physics-based models via machine learning methods.

Complex terrain, the sparse distribution of rain gauges, and the poor resolution and quality of satellite data in remote areas severely restrict the development of watershed hydrological modeling, meteorology, and ecological research. In this study, based on the relationship between cloud optical and physical properties and precipitation, a daily geographically weighted regression (GWR) precipitation downscaling model was constructed for the Three Rivers Source region, China, for the period from 2010 to 2014. The GWR precipitation downscaling model combined three different satellite precipitation datasets (CMORPH, IMERG, and ERA5) which were downscaled from a coarse resolution (0.25° and 0.1°) to a fine resolution (1 km). At the same time, the preliminary downscaling results were calibrated and verified by employing the geographic difference analysis (GDA) and geographic ratio analysis (GRA) methods combined with rainfall data. Finally, the analytical hierarchy process (AHP) and the entropy weight method (EW) were adopted to fuse the three downscaled and calibrated satellite precipitation datasets into the merged satellite precipitation dataset (MSP), which provides a higher quality of data (CC = 0.790, RMSE = 2.189 mm/day, and BIAS = 0.142 mm). In summary, the downscaling calibration and precipitation fusion scheme proposed in this study is suitable for obtaining high-resolution daily precipitation data in the Three Rivers Source region with a complex climate and topography.
