Short summary
Short summary
We built a hybrid machine learning model that first screened many weather and land metrics, retaining only the most informative metrics, and then learned from decades of monthly records to predict droughts. Through the test of 28 regions in the Huaihe River Basin of China from 2011 to 2020, its accuracy is higher than that of multiple comparison models.

This study aims to analyze the impact of climate change and watershed characteristics on the spread of drought. Based on the GAMLSS (Generalized Additive Model for Location, Scale, and Shape) framework and Copula model, the probability and threshold of drought spread in different seasons were calculated without being affected by climate factors. The results show that: the spatiotemporal variability of drought spread is influenced by climate change and watershed characteristics

This study proposes an innovative method for predicting drought in the Huaihe River Basin of China using advanced machine learning and interpretable artificial intelligence techniques. By analyzing more than 50 years of data, the model successfully predicted four drought categories with an accuracy of 79.9 %. It used explanatory methods to analyze the contribution of different drought influencing factors, providing key insights for early warning systems and water resources planning.

It is an important disaster reduction strategy to forecast hydrological drought. In order to analyse the impact of human activities on hydrological drought, we constructed the human activity factor based on the method of restoration. With the increase of human index (HI) value, hydrological droughts tend to transition to more severe droughts. The conditional distribution model involving of human activity factor can further improve the forecasting accuracy of drought in the Luanhe River basin.

Short summary
This study examines the risk of possible water shortages in the Huaihe River Basin and explores whether dry periods can be predicted more reliably. Using decades of daily environmental records, we built a model that separates complex signals into simpler parts and learns their patterns. It forecasts dry conditions more accurately than earlier methods and performs well across regions and time spans. The findings can help the basin prepare for potential water shortages and support better planning.
