In recent decades, multiple LSEPs have been constructed in the Yangtze Estuary, and the impacts of single project have been well studied, but their cumulative impacts remain elusive. This study investigates Yangtze Estuary morphological changes from 1958

Coastal groundwater salinization induced by marine transgression, sea level rising, and/or seawater intrusion due to anthropogenic activities has been a challenge for water security worldwide. Understanding of the spatial distribution of saline water and its sources is important for the protection of fresh groundwater resources from salinization necessitates. In this study, the processes of groundwater

The vulnerability of cities to flood has become a global issue due to urbanization. Although various studies have been evaluated urban flood resilience using various indicators, a comprehensive flood resilience assessment method considering the entire process of stormwater runoff production and concentration remains a gap.

The data assimilator, pre-processor, and post-processor in the ensemble hydrological prediction system (EHPS) are designed to handle uncertainties related to initial hydrological conditions, meteorological inputs, and hydrological predictions, respectively. They play distinct roles in the forecasting chain and may complement each other, but the interaction among them has not been well understood so

Urban drainage modelling is essential for effective city planning and flood management. The increasing complexity of urban environments and the growing availability of high-resolution data have led to the need to develop more sophisticated and freely accessible urban drainage models.

Short-term water demand forecasting is essential for ensuring the sustainable use of water resources. The accuracy of water demand forecasting directly impacts the rationality of water resources management and the effectiveness of scheduling. Therefore, it is vital to accurately forecast water demand across various timescales. Based on this motivation, we propose an improved patch time series Transformer

The accuracy of groundwater flow simulations is heavily influenced by the geological structure model. Relying on a single deterministic model does not effectively address the inherent uncertainties.

In the context of ongoing climate change and extreme rainfall events, urban flooding has become a global challenge. The layout of urban buildings is recognized as a crucial factor influencing flooding. The ability of a city to respond promptly and recover quickly from floods is referred as ’urban flood resilience’. To deepen our understanding of this issue, urban flooding simulation and resilience

Over 75 % of the terrestrial territory in the Northern Hemisphere is subjected to seasonally freezing and thawing cycles. The naturally occurred soil freezing processes induce the migration of soil water from unfrozen underlying depths towards the freezing front under gradients of matric potential, temperature and vapor concentration/pressure. The upward moving soil water and vapor change to ice near

Extreme daily evaporation from reservoir surfaces can lead to significant short-term water losses, affecting water quality, water supply, and reservoir operation strategies. Historical trends in daily reservoir evaporation events have eluded the scientific and operational communities, largely due to a lack of long-term, consistent data record. This study quantifies trends in extreme daily reservoir

Atmospheric Rivers (ARs) play a pivotal role in precipitation dynamics, often leading to hazardous flood events. While much research has investigated the relationship between ARs and precipitation in the northern hemisphere, the role of ARs in modulating Australia’s precipitation has received little attention. The ambiguity surrounding AR definition and identification criteria has resulted in the emergence
