Modern hydrology of a typical Arctic fjord (Hornsund, SW Spitsbergen, Sval− bard) was investigated and compared with commonly used in paleoceanography proxies: benthic foraminiferal assemblages and their stable isotope ( 18O and 13C) composition. The benthic foraminifera from Hornsund comprised 45 species and 28 genera. Their spatial variations follow the zonation pattern, resulting from the in...
Abstract. Ecosystems in arid areas are fragile and easily disturbed by various natural human factors. As tracers widely exist nature, stable isotopes can be valuable for studying environmental change the water cycle. From 2015 to 2020, we took Shiyang River basin, which has highest utilization rate of resources most prominent contradiction use, as a typical demonstration basin establish improve...

Abstract The stable isotope ratios of oxygen and hydrogen in polar ice cores are known to record environmental change, they have been widely used as a paleothermometer. Although it is be simplification, the relationship often explained by invoking single condensation pathway with progressive distillation temperature at location core. In reality, physical factors complicated, recent studies iden...
Abstract The history of Nordic Hydrology/Hydrology Research is described from its initiation in 1970 to current state 2021. This includes dramatic changes leading first an ownership transformation Association for Hydrology (NAH) 1976, and much later, 2004, a joint between NAH, British Hydrological Society IWA Publishing. development publication policy during time covered as well.
This article presents snow hydrology updates made to iTree-Hydro, previously called the Urban Forest Effects—Hydrology model. iTree-Hydro Version 1 was a warm climate model developed by the USDA Forest Service to provide a process-based planning tool with robust water quantity and quality predictions given data limitations common to most urban areas. Cold climate hydrology routines presented in...
ABSTRACT Karst environments preserve some of the best archives past climate, vegetation, hydrology, anthropogenic impact, and landscape evolution providing that a reliable chronology can be established. Here we present an example system Plitvice Lakes (Dinaric karst, Croatia), which is characterized by intensive tufa lake sediment formations. The radiocarbon dating method, combined with other m...
