Modeling of vegetation dynamics in hydrological models for the assessment of the effects of climate change on evapotranspiration and groundwater recharge
vegetation dynamics hydrological
2010/2/3
Vegetation affects water balance of the land surface by e.g. storage of precipitation water in the canopy and soil water extraction by transpiration. Therefore, it is essential to consider the role of...
The Combination of Simulated Discharges of Hydrological Models
Combination Simulated Discharges Hydrological Models
2009/10/27
Hydrological models are frequently used to simulate streamflow. A method for
improving performance is to combine the simulated discharges of two or more
models. Three different methods are given in ...
Spring Characteristics and Hydrological Models of Catchments
Spring Characteristics Hydrological Models Catchments
2009/10/27
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...
HESS Opinions “Crash tests for a standardized evaluation of hydrological models”
catchments hydrological models
2009/10/10
As all hydrological models are intrinsically limited hypotheses on the behaviour of catchments, models – which attempt to represent real-world behaviour – will always remain imperfect. To make progre...
A novel approach to parameter uncertainty analysis of hydrological models using neural networks
