A Comprehensive Model for Correcting Point Precipitation
Comprehensive Model Point Precipitation
2009/10/23
Wind induced errors in precipitation measurements result in systematic deficits, which are particularly large when the precipitation falls as snow combined with high wind speed. The actual magnitude o...
Adaptive Use of a Conceptual Model for Real Time Flood Forecasting
Adaptive Use Conceptual Model Real Time Flood Forecasting
2009/10/23
This paper investigates the adaptive use of a simple conceptual lumped rainfallrunoff
model based on a Probability Distributed Model complemented with a
Geomorphological Unit Hydrograph. Three diffe...
A Simple Automatic Calibration Routine for the HBV Model
Automatic Calibration Routine HBV Model
2009/10/23
A simple, but efficient, method for automatic calibration of the conceptual HBV
rainfall-runoff model was developed. A new criterion, which combines the com-
monly used efficiency criterion R 2 and ...
A Model for Water Exchange Between the Baltic Sea and the Gulf of Riga
Water Exchange Baltic Sea Gulf of Riga
2009/10/23
A model for water exchange of a basin connected to the open sea by two channels
has been worked out. The model is applied on the Gulf of Riga, where the
water exchange processes versus strong landba...
The Effect of Climate Change on River Flow and Snow Cover in the NOPEX Area Simulated by a Simple Water Balance Model
Climate Change River Flow Snow Cover NOPEX Area
2009/10/23
Within the next few decades, changes in global temperature and precipitation
patterns may appear, especially at high latitudes. A simple monthly water-balance
model of the NOPEX basins was developed...
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. ...
Mathematical Model of Hydrological Processes METQ98 and its Applications
Mathematical Model Hydrological Processes METQ98 Applications
2009/10/23
The mathematical model METQ98 for runoff simulation is described. The
METQ98 is developed from the model METUL (Krams and Ziverts 1993). Input
data for the model are daily mean values of air tempera...
Application of a Global Discharge Model to Atmospheric Model Simulations in the BALTEX Region
Global Discharge Model Atmospheric Model Simulations BALTEX Region
2009/10/23
In this study, a hydrological discharge model is presented which may be applied
as a tool to validate the simulation of the hydrologic cycle of atmospheric models
that are used in climate change stu...
A Recession-Forecast Model for the Blue Nile River
Recession-Forecast Model Blue Nile River
2009/10/23
An analytical model for the forecasting of the Blue Nile River low flow is developed
and compared with the current modified similar year method. The
model is based on the general non-linear reservoi...
Model Sophistication in Relation to Scales in Snowmelt Runoff Modeling
Model Sophistication Scales Snowmelt Runoff Modeling
2009/10/23
Snowmelt induced runoff from river basins is usually successfully simulated using
a simple degree-day approach and conceptual rainfall-runoff models. Fluctuations
within the day can not be described...
Estimation of Regional Parameters in a Macro Scale Hydrological Model
Regional Parameters Macro Scale Hydrological Model
2009/10/22
Macro-scale hydrological modelling implies a repeated application of a model
within an area using regional parameters. These parameters are based on climate
and landscape characteristics, and they a...
Interception of a Dense Spruce Forest,Performance of a Simplified Canopy Water Balance Model
Interception Dense Spruce Forest Water Balance Model
2009/10/22
The process of interception was studied in 25-year-old dense stands of Norway
spruce in South Sweden. The throughfall was measured intensively during one
month and extensively during four growing se...
Calculating Irradiance Penetration into Water Bodies from the Measured Beam Attenuation Coefficient,II:Application of the Improved Model to Different Types of Lakes
Irradiance Penetration Water Bodies Improved Model
2009/10/22
The method suggested earlier for estimating the spectra of diffuse attenuation
coefficient of light in the water bodies relying on the beam attenuation coefficient
measured from water samples, was i...
An Energy Balance Based HBV- Model with Application to an Arctic Watershed on Svalbard,Spitsbergen
Energy Balance HBV- Model Arctic Watershed
2009/10/22
In several studies of snowmelt using the temperature index method from the original HBV-model, the model fails to predict the timing of the snowmelt and underestimates the intensities on occasions wit...
Fuzzy Clustering Neural Network as Flood Forecasting Model
Fuzzy Clustering Neural Network Flood Forecasting Model
2009/10/22
Flood forecasting is always a challenge in Taiwan, which has a subtropical climate
and high mountains. This paper develops a fuzzy clustering neural network
(FCNN), and implements this novel structu...
