The new Scientific Decade 2013–2022 of IAHS, entitled "Panta Rhei—Everything Flows", is dedicated to research activities on change in hydrology and society. purpose Panta Rhei reach an improved interpretation the processes governing water cycle by focusing their changing dynamics connection with rapidly human systems. practical aim improve our capability make predictions resources support sustainable societal development a environment. concept implies focus hydrological systems as interface...
Global land water underpins livelihoods, socioeconomic development, and ecosystems. It remains unclear how availability has changed in recent decades. Using an ensemble of observations, we quantified global over the past two We show that Southern Hemisphere dominated declining trend from 2001 to 2020. The significant decrease occurs mainly South America, southwestern Africa, northwestern Australia. In Northern Hemisphere, complex regional increasing decreasing trends cancel each other,...
Sixteen small catchments in the Maroondah region of Victoria, Australia were analysed using rainfall, temperature and streamflow time series with a rainfall–runoff model whose parameters efficiently characterize hydrological response catchment. A set catchment attributes for each these was then compared associated characteristics as estimated by model. The constant governing quickflow recession (τq) related to drainage network area. slowflow (τs) slope shape parameter evapotranspirative...
This study examined daily streamflow response over up to four decades in northwest conifer forest and eastern deciduous sites the United States. We used novel methods analyze observations of climate spanning more than 900 basin years record at 14 treated/control pairs where removal regrowth experiments were underway period 1930–2002. In 1 5‐year after removal, maximum increases ranged from 2 3 mm sites, 6 8 sites. Significant spring surpluses persisted for 35 basins, but winter deficits...
Abstract Accurate prediction of runoff signatures is important for numerous hydrological and water resources applications. However, there are lack comprehensive evaluations various approaches predicting signatures. This study, the first time, introduces regression tree ensemble approach compares it with other three widely used (multiple linear regression, multiple log‐transformed modeling) assessing accuracy 13 characteristics or signatures, using a large data set from 605 catchments across...
Abstract Because remote sensing (RS) data are spatially and temporally explicit available across the globe, they have potential to be used for predicting runoff in ungauged catchments poorly gauged regions, a challenging area of research hydrology. There is use remotely sensed calibrating hydrological models regions with limited streamflow gauges. This study conducts comprehensive investigation on how incorporate gridded evapotranspiration (AET) water storage constraining model calibration...
Projections of streamflow under future climate are essential for developing adaptation strategies in the water and related sectors.

Abstract Water use by vegetation can be closely linked to streamflow patterns on a variety of time scales. However, many the details these linkages are poorly understood. We compared diel (24 h) transpirational water with in small headwater basin that displays marked variation during summer months. The study site was western Oregon. Our objectives were to: (1) determine phase shift, i.e. lag between maximum transpiration and minimum streamflow, strength correlation at lag; (2) amount is...
Abstract. Large Arctic river basins experience substantial variability in climatic, landscape, and permafrost conditions. However, the processes behind observed changes at scale of these are relatively poorly understood. While most studies have been focused on “Big 6” rivers – Ob', Yenisey, Lena, Mackenzie, Yukon, Kolyma few or no assessments exist for small medium-sized basins, such as Yana Indigirka River basins. Here, we provide a detailed analysis streamflow data from 22 hydrological...
ABSTRACT We describe the method and performance of a bias‐correction applied to high‐resolution (˜10 km) simulations from stretched‐grid Regional Climate Model ( RCM ) over Tasmania, Australia. The is quantile mapping empirical cumulative frequency distributions. Corrections are at daily time step five variables: rainfall, potential evaporation (PE), solar radiation, maximum temperature minimum temperature. calculated independently for each season. show that distributions can be highly...

Abstract Southeastern Australia experienced the worst drought of instrumental record from 1997 to 2009, which was broken by Australia's wettest 2 year period on (2010/2011). This primarily a cool season (April October) phenomenon. In contrast, breaking warm (November March) reduction in winter rainfall along with an absence very wet months led greater streamflow across region than would be anticipated based 12% mean annual alone. The results presented this article have linked extent,...
The Murray-Darling Basin (MDB) in south-eastern Australia is one of the world’s largest rivers, draining an area just over 1 million km2. However, being primarily a semi-arid region, its discharge much smaller than that from other similarly sized rivers worldwide. Despite relatively low discharge, MDB most significant agricultural contributing $30 billion to Australian economy each year. also home thriving ecosystem with 100 species native and migratory birds, 50 fish.Climate...
Abstract. Gap-filling streamflow data is a critical step for most hydrological studies, such as trend, flood, and drought analysis response variable estimates predictions. However, there lack of quantitative evaluation the gap-filled accuracy in studies. Here we show that when missing rate less than 10 %, obtained using calibrated models perform almost same benchmark (less 1 % missing) estimating annual trends 217 unregulated catchments widely spread across Australia. Furthermore, relative...
Predicting floodplain inundation under a changing climate is essential for adaptive management of water resources and ecosystems worldwide. This study presents framework combining satellite observations hydrological modeling to explore changes in inundation. We examine variability, trends, frequency across the Murray-Darling Basin (MDB), Australia's largest river system, over past 35 years (1988-2022). Our analysis shows that annual maximum 30-day runoff primary factor influencing Using this...
Hydrological systems present several difficulties for modellers. A data-based approach utilizing objective statistical analysis of output and/or input-output time series behaviour has much to offer, both understanding the response dynamics and future hypothesis formulation improved model structure, as well good predictive capacity. In this paper, essential elements tools a approach, using an Unobserved Components (UC) model, are presented illustrated with two examples.
