Changes in runoff regime. The Lomnice catchment case study
Bilan model hydrological regime mass curve method water balance
2015/3/13
Water distribution in landscape is essentially influenced by the nature of the catchment rainfall-runoff process. Firstly, this paper presents an analysis of trends in the rainfall-runoff regime of th...
Estimating Precipitation Phase using a Psychrometric Energy Balance Method: Tests in a Canadian Rockies Headwaters Catchment
snowfall rainfall, precipitation phase change Canadian Rockies energy balance model
2014/4/3
Precipitation phase is fundamental to catchment hydrological response to precipitation events in
cold regions and is especially variable over time and space in mountains. Phase is controlled by
t...
Effects of Excess Rainfall Time Distribution on Catchment Area Hydrograph
Excess Rainfall Time Catchment Area Hydrograph
2009/10/27
The effect of triangular excess hyetographs on catchment area runoff process is
investigated, thereby fixing the precipitation time. The approach accounts for
the kinematic wave theory and allows a ...
Predicting Sedimentgraphs for a Small Agricultural Catchment
Predicting Sedimentgraphs Small Agricultural Catchment
2009/10/23
The key components of a sedimentgraph prediction procedure for small agricultural
catchments are outlined in the paper. An instantaneous unit sedimentgraph
(IUSG) based on the IUH and on a dimension...
Snow Cover Modelling as a Tool for Climate Change Assessment in a Swiss Alpine Catchment
Snow Cover Modelling Climate Change Assessment Swiss Alpine Catchment
2009/10/23
The daily step conceptual hydrological model IRMB (Integrated Runoff Model
= Bultot) is further developed by the addition of a module designed to calculate
the energy balance in high spatial resolut...
Seasonal Water Balance of an Alpine Catchment as Evaluated by Different Methods for Spatially Distributed Snowmelt Modelling
Seasonal Water Balance Alpine Catchment Snowmelt Modelling
2009/10/22
The application of three temperature-index based models and of one energy balance
based snowmelt model was investigated. The snow models were integrated
in the spatially distributed hydrological mod...
Modelling of monsoon rainfall for a mesoscale catchment in North-West India II：stochastic rainfall simulations
circulation patterns monsoon rainfall mesoscale catchment
2009/5/15
Within this study we present a robust method for generating precipitation time series for the Anas catchment in North Western India. The method employs a multivariate stochastic simulation model that ...
Modelling of monsoon rainfall for a mesoscale catchment in North-West India I：assessment of objective circulation patterns
monsoon rainfall circulation patterns mesoscale catchment
2009/5/15
Within the present study we shed light on the question whether objective circulation patterns (CP) classified from either the 500 HPa or the 700 HPa level may serve as predictors to explain the spatio...
Investigation of dominant hydrological processes in a tropical catchment in a monsoonal climate via the downward approach
hydrological processes tropical catchment monsoonal climate
2009/5/15
This study explores the dominant processes that may be responsible for the observed streamflow response in Seventeen Mile Creek, a tropical catchment located in a monsoonal climate in Northern Territo...
Threshold effects in catchment storm response and the occurrence and magnitude of flood events：implications for flood frequency
catchment storage flood frequency flood
2009/5/12
The aim of this paper is to illustrate the effects of selected catchment storage thresholds upon runoff behaviour, and specifically their impact upon flood frequency. The analysis is carried out with ...
Aspects of seasonality and flood generating circulation patterns in a mountainous catchment in south-eastern Germany
flood generating seasonality circulation patterns south-eastern Germany
2009/5/12
Analyses of discharge series, precipitation fields and flood producing atmospheric circulation patterns reveal that two governing flood regimes exist in the Mulde catchment in south-eastern Germany: f...
Predictions of rainfall-runoff response and soil moisture dynamics in a microscale catchment using the CREW model
rainfall-runoff response microscale catchment soil moisture dynamics
2009/5/7
Predictions of catchment hydrology have been performed generally using either physically based, distributed models or conceptual lumped or semi-distributed models. In recognition of the disadvantages...
