Estimation of Parameter Uncertainty in the HBV Model
Estimation of Parameter Uncertainty HBV Model
2009/10/23
Usually the HBV model is calibrated by seeking one optimal parameter set that
represents the catchment. From experience we know, however, that it is hardly
poss~ble to find an unique parameter set. ...
Uncertainty in parameterisation and model structure affect simulation results in coupled ecohydrological models
parameterisation vegetation structure ecohydrological models
2009/10/10
In this paper we develop and apply a conceptual ecohydrological model to investigate the effects of model structure and parameter uncertainty on the simulation of vegetation structure and hydrological...
Note on semiclassical uncertainty relations
Husimi distributions Fisher information Localizability in phase-space
2010/7/5
An important manifestation of the Uncertainty Principle, one of the cornerstones of our present understanding of Nature, is that related to semiclassical localization in phase-space. We wish here to a...
A novel approach to parameter uncertainty analysis of hydrological models using neural networks
hydrological models neural networks Artificial Neural Network
2009/7/22
In this study, a methodology has been developed to emulate a time consuming Monte Carlo (MC) simulation by using an Artificial Neural Network (ANN) for the assessment of model parametric uncertainty. ...
Uncertainty in river discharge observations：a quantitative analysis
river discharge quantitative analysis
2009/7/22
This study proposes a framework for analysing and quantifying the uncertainty of river flow data. Such uncertainty is often considered to be negligible with respect to other approximations affecting h...
Structure of the transport uncertainty in mesoscale inversions of CO2 sources and sinks using ensemble model simulations
transport uncertainty mesoscale inversions CO2 sources sinks model simulations
2010/1/20
We study the characteristics of a statistical ensemble of mesoscale simulations in order to estimate the model error in the simulation of CO2 concentrations. The ensemble consists of ten members and t...
Uncertainty of solute flux estimation in ungauged small streams：potential implications for input-output nutrient mass balances at stream reach scale
nutrient retention hydrological conditions
2009/5/18
Input-output mass balances within stream reaches provide in situ estimates of stream nutrient retention/release under a wide spectrum of hydrological conditions. Providing good estimates of the mass b...
Spatial and temporal patterns of land surface fluxes from remotely sensed surface temperatures within an uncertainty modelling framework
Generalised Likelihood Uncertainty Estimation land surface fluxes surface temperatures
2009/5/18
Characterising the development of evapotranspiration through time is a difficult task, particularly when utilising remote sensing data, because retrieved information is often spatially dense, but temp...
Cascading model uncertainty from medium range weather forecasts (10 days) through a rainfall-runoff model to flood inundation predictions within the European Flood Forecasting System (EFFS)
Generalised Likelihood Uncertainty Estimation weather forecasts uropean Flood Forecasting System
2009/5/18
The political pressure on the scientific community to provide medium to long term flood forecasts has increased in the light of recent flooding events in Europe. Such demands can be met by a system co...
Precipitation forecasts and their uncertainty as input into hydrological models
rainstorms European Centre for Medium-Range Weather Forecasts
2009/5/18
Torrential streams and fast runoff are characteristic of most Slovenian rivers and extensive damage is caused almost every year by rainstorms affecting different regions of Slovenia. Rainfall-runoff m...
Uncertainty in soil physical data at river basin scale – a review
soil physical river basin scale
2009/5/15
For hydrological modelling studies at the river basin scale, decision makers need guidance in assessing the implications of uncertain data used by modellers as an input to modelling tools. Simulated ...
Uncertainty in geological and hydrogeological data
hydrogeological data geological environmental data
2009/5/13
Uncertainty in conceptual model structure and in environmental data is of essential interest when dealing with uncertainty in water resources management. To make quantification of uncertainty possible...
Uncertainty, sensitivity analysis and the role of data based mechanistic modeling in hydrology
sensitivity analysis mechanistic modeling hydrology
2009/5/8
In this paper, we discuss a joint approach to calibration and uncertainty estimation for hydrologic systems that combines a top-down, data-based mechanistic (DBM) modelling methodology; and a bottom-u...
Regional climate model data used within the SWURVE project – 2：addressing uncertainty in regional climate model data for five European case study areas
uncertainty European regional climate mode temperature
2009/5/8
To aid assessments of the impact of climate change on water related activities in the case study regions (CSRs) of the EC-funded project SWURVE, estimates of uncertainty in climate model data need to ...
Towards integrated environmental models of everywhere: uncertainty, data and modelling as a learning process
Developing integrated environmental models Europe Water Framework Directive
2009/5/6
Developing integrated environmental models of everywhere such as are demanded by the requirements of, for example, implementing the Water Framework Directive in Europe, is constrained by the limitatio...
