Runoff trends analysis and future projections of hydrological patterns in small forested catchments
climate change flow pattern headwater catchments hydrological modelling
2015/3/10
The aims of the present study were (i) to evaluate trends in runoff from small forested catchments of the GEOMON (GEOchemical MONitoring) network during the period 1994–2011, and (ii) to estimate the ...
Impact of landuse on runoff in mountain catchments of different scales
hydrological regime landuse change
2015/2/4
The paper presents two approaches to the analysis of the impacts of landuse changes on hydrological regime in mountain catchments of northern Slovakia. An intersite comparison of measured data along t...
Annual changes in the chemical composition of stream water in small catchments with different land-use (Carpathian Foothills, Poland)
river water chemistry water pollution nutrient compounds flow tendency
2015/2/4
The aim of the study was to identify the factors that influence annual changes in the chemical composition of stream waters. The research area was located in the marginal zone of the Carpathian Foothi...
Streamflow trends in Europe: evidence from a dataset of near-natural catchments
Streamflow trends Europe dataset
2010/12/22
Streamflow observations from near-natural catchments are of paramount importance for detection and attribution studies, evaluation of large-scale model simulations, and assessment of water management,...
Performance and reliability of multimodel hydrological ensemble simulations based on seventeen lumped models and a thousand catchments
multimodel hydrological ensemble simulations seventeen lumped models
2010/12/22
This work investigates the added value of ensembles constructed from seventeen lumped hydrological models against their simple average counterparts. It is thus hypothesized that there is more informat...
The role of climatic and terrain attributes in estimating baseflow recession in tropical catchments
climatic terrain attributes estimating baseflow recession tropical catchments
2010/12/22
The understanding of low flows in rivers is paramount more than ever as demand for water increases on a global scale. At the same time, limited streamflow data to investigate this phenomenon, particul...
Climate and terrain factors explaining streamflow response and recession in Australian catchments
Climate and terrain factors streamflow response recession Australian catchments
2010/2/1
Daily streamflow data were analysed to assess which climate and terrain factors best explain streamflow response in 183 Australian catchments. Assessed descriptors of catchment response included the p...

Experience Field Testings SHE Research Catchments
2009/10/28
The development of the European Hydrologic System (SHE) has now
reached such a stage, that it is ready for practical applications. Extensive field
testings and associated developments have been carr...
On Soil Retention Curves and Hydrological Forecasting in Ungauged Catchments
Soil Retention Curves Hydrological Forecasting Ungauged Catchments
2009/10/28
In many physically based hydrological models, there is the requirement to
specify the suction-moisture curve of the soil system. This paper shows that
where the suction moisture curve is known, then...

The Astdalen catchment (373 km2) represents largely a natural ecosystem,
typical for the higher central and southern parts of the Scandinavian Peninsula.
It is underlain by fractured sedimentary roc...
Modelling the Effects of Acid Deposition:Estimation of Long-Term Water Quality Responses in Forested Catchments in Finland
Acid Deposition Long-Term Water Quality Responses Forested Catchments
2009/10/27
A modelling study has been undertaken to investigate long-term changes in
surface water quality in two contrasting forested catchments; Yli-Knuutila, with
high concentrations of base cations and sul...
Calcium Budgets for Catchments as Interpreted by Strontium Isotopes
Calcium Budgets Catchments Strontium Isotopes
2009/10/27
Strontium isotopes in precipitation, soil and runoff water can be used to establish
a ratio of wet plus dry deposited Sr to Sr released by weathering. This ratio
is especially enhanced in areas with...
