Drylands are home to more than 38% of the world's population and are one of the most
sensitive areas to climate change and human activities. This review describes recent …

Drought is a complex natural hazard that impacts ecosystems and society in many ways.
Many of these impacts are associated with hydrological drought (drought in rivers, lakes …

Regional rainfall–runoff modeling is an old but still mostly outstanding problem in the
hydrological sciences. The problem currently is that traditional hydrological models degrade …

Rainfall–runoff modelling is one of the key challenges in the field of hydrology. Various
approaches exist, ranging from physically based over conceptual to fully data-driven …

Abstract Model calibration and validation are critical in hydrological model robustness
assessment. Unfortunately, the commonly used split‐sample test (SST) framework for data …

This paper is the outcome of a community initiative to identify major unsolved scientific
problems in hydrology motivated by a need for stronger harmonisation of research efforts …

We introduce the first catchment dataset for large sample studies in Chile. This dataset
includes 516 catchments; it covers particularly wide latitude (17.8 to 55.0∘ S) and elevation …

Research gaps in understanding flood changes at the catchment scale caused by changes
in forest management, agricultural practices, artificial drainage, and terracing are identified …

Floods are a natural hazard that affect communities worldwide, but to date the vast majority
of flood hazard research and map** has been undertaken by wealthy developed nations …

Abstract Karst regions represent 7–12% of the Earth's continental area, and about one
quarter of the global population is completely or partially dependent on drinking water from …
