Evapotranspiration modelling at large scale using near-real time MSG SEVIRI derived data
Evapotranspiration modelling using near-real MSG SEVIRI
2011/3/4
We present an evapotranspiration (ET) model developed in the framework of the EUMETSAT "Satellite Application Facility" (SAF) on Land Surface Analysis (LSA). The model is a simplified Soil-Vegetation-...
Hydrological response unit-based blowing snow modelling over an alpine ridge
snow modelling an alpine ridge
2010/4/3
Snow redistribution by wind and the resulting accumulation regimes were simulated for
two winters over an alpine ridge transect located in the Canada Rocky Mountains. Simulations were performed using...
The extrapolation of artificial neural networks for the modelling of rainfall ATitlemdash;runoff relationships
artificial neural networks modelling rainfall ATitlemdash runoff relationships
2009/12/4
The last decade has seen increasing interest in the application of Artificial Neural Networks (ANNs) for the modelling of the relationship between rainfall and streamflow. Since multi-layer, feed-forw...
Modelling the Effect of Climatic Warming on the Hofsjökull Ice Cap,Central Iceland
Climatic Warming Hofsjö kull Ice Cap Central Iceland
2009/10/26
A time-dependent cylindrically symmetric computer model of the Hofsjokull
ice cap, Central Iceland, has been defined in order to investigate the time-scale
of possible glacier variations. The model ...
Impacts of urbanisation on hydrological processes are different for snowmelt
and rainfall events. Furthermore, snowmelt and runoff generation differ between
rural and urban areas. Within an urban ar...
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...
Rainfall Runoff Modelling Based on Genetic Programming
Rainfall Runoff Modelling Genetic Programming
2009/10/22
The runoff formation process is believed to be highly non-linear, time varying,
spatially distributed, and not easily described by simple models. Considerable
time and effort has been directed to mo...
Snow-Distribution Modelling in the Ammassalik Region,South East Greenland
Snow-Distribution Modelling Ammassalik Region South East Greenland
2009/10/22
The Ammassalik region is characterized by a strong alpine relief, with altitudes
up to 1,000 m. Glaciers are located mainly on the western side of ridges. The climate
is low arctic, with annual prec...
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...
A combined Pòlya process and mixture distribution approach to rainfall modelling
rainfall modelling stochastic model
2009/6/8
A new probabilistic interpretation of at site rainfall sequences is introduced for the development of a stochastic model of rain.
The model, is divided into two sub models; the first one describing t...
Significance of spatial variability in precipitation for process-oriented modelling：results from two nested catchments using radar and ground station data
rainfall spatial resolution temporal resolution
2009/5/18
The importance of considering the spatial distribution of rainfall for process-oriented hydrological modelling is well-known. However, the application of rainfall radar data to provide such detailed s...
Modelling of monsoon rainfall for a mesoscale catchment in North-West India II：stochastic rainfall simulations

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...
Inverse distributed hydrological modelling of Alpine catchments
Alpine catchments Inverse distributed
2009/5/13
Even in physically based distributed hydrological models, various remaining parameters must be estimated for each sub-catchment. This can involve tremendous effort, especially when the number of sub-...
