Sensitivity of urban drainage wash-off models:compatibility analysis of HydroWorks QM and MouseTrap using CDF relationships
urban drainage wash-off models compatibility analysis HydroWorks QM MouseTrap CDF relationships
2009/12/4
One of the key aspects in urban drainage (water quality) modelling is the accurate simulation of the input into such models. The modelling of surface sediment build-up, erosion and wash-off is discuss...
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...

2009/10/28
High precipitation amounts of strongly varying ionic composition make the
western parts of southern Norway well-suited for studies of certain relationships
between precipitation chemistry, hydrology...
Regional Flood Relationships by Nonparametric Regression
Regional Flood Relationships Nonparametric Regression
2009/10/26
Since some theoretical assumptions needed in linear regression are not always
fulfilled in practical applications, nonparametric regression was investigated as
an alternative method in regional floo...

2009/10/13
A hydrochemical study of the Hindon river system in western Uttar Pradesh (India) has been carried out with the objective to examine variation in water quality characteristics within the river system,...
Relationships between spruce plantation age, solute and soil chemistry in Hafren forest
dissolved organic nitrogen Acid neutralizing capacity soil chemistry
2009/6/8
Rain, throughfall, soil waters from surface peaty O horizon and deeper mineral B horizon, and stream water, were collected every four weeks for one year in a moorland catchment, and in four forested c...
Relationships between statistics of rainfall extremes and mean annual precipitation：an application for design-storm estimation in northern central Italy
mean annual precipitation rainfall extremes
2009/5/13
Several hydrological analyses need to be founded on a reliable estimate of the design storm, which is the expected rainfall depth corresponding to a given duration and probability of occurrence, usual...
Neural network modelling of non-linear hydrological relationships
Neural network modelling non-linear hydrological relationships
2009/5/13
Two recent studies have suggested that neural network modelling offers no worthwhile improvements in comparison to the application of weighted linear transfer functions for capturing the non-linear na...
Generalisation of physical habitat-discharge relationships
Physical Habitat Simulation river ecosystem health river flows
2009/5/6
Physical habitat is increasingly used worldwide as a measure of river ecosystem health when assessing changes to river flows, such as those caused by abstraction. The major drawback with this approac...
Extension of the Representative Elementary Watershed approach for cold regions：constitutive relationships and an application
