The Two-layer Surface Energy Balance Parameterization Scheme (TSEBPS) for estimation of land surface heat fluxes
Two-layer Surface Energy Balance Parameterization Scheme (TSEBPS) estimation land surface heat fluxes
2010/4/7
A Two-layer Surface Energy Balance Parameterization Scheme (TSEBPS) is proposed for the estimation of surface heat fluxes using Thermal Infrared (TIR) data over sparsely vegetated surfaces. TSEBPS is ...
Investigation of a parameter estimation method for contaminant transport in aquifers
Investigation parameter estimation method contaminant transport aquifers
2009/12/4
Real world groundwater aquifers are heterogeneous and system variables are not uniformly distributed across the aquifer. Therefore, in the modelling of the contaminant transport, we need to consider t...
Estimation and propagation of parametric uncertainty in environmental models
Estimation propagation parametric uncertainty environmental models
2009/12/4
It is proposed that a numerical environmental model cannot be justified for predictive tasks without an implicit uncertainty analysis which uses reliable and transparent methods. Various methods of un...
An adaptive neuro-fuzzy inference system for the post-calibration of weather radar rainfall estimation
adaptive neuro-fuzzy inference system post-calibration weather radar rainfall estimation
2009/12/4
An Adaptive Neuro-Fuzzy Inference System, based on a jack-knife approach, is proposed for the post-calibration of weather radar rainfall estimation exploiting available raingauge observations. The met...
Estimation of the impact of short-term fluctuations in inputs on temporally aggregated outputs of process-oriented models
short-term fluctuations inputs outputs process-oriented models
2009/12/4
Process-oriented models driven by highly resolved meteorological inputs and comprising a short internal time step are sometimes used to predict substance fluxes in air, soil and water over fairly long...
AN ESTIMATION OF EVAPOTRANSPIRATION BY MEANS OF THE WATER BALANCE OF A SOIL COLUMN
ESTIMATION OF EVAPOTRANSPIRATION MEANS OF THE WATER BALANCE SOIL COLUMN
2009/10/30
In this paper water-balance studies of a soil column at an observation site
at Ulvsunda, Stockholm, are reported. The change of the water storage in
the soil was obtained from soil moisture measurem...

Estimation of Parameters of a Uniformly Nonlinear Surface Runoff Model
Estimation of Parameters Uniformly Nonlinear Surface Runoff Model
2009/10/29
The surface runoff model, based on the concept of uniform nonlinearity
(Dooge 1967), has three parameters. It is shown that these parameters can be
estimated from the informaion that can be easily o...

Estimation Transmissivity Permeability Swedish Bedrock
2009/10/29
Statistical analysis of pumping-test data from wells have been used to calculate
average values of transmissivity and permeability in different Swedish rocks. The
influence of the well-loss on the c...
Estimation of Parameters of Converging Overland Flow Model
Estimation Parameters Overland Flow Model
2009/10/29
The converging overland flow model contains five parameters, three geometric
and two kinematic. An attempt is made in this study to estimate these parameters
utilizing watershed topographic characte...
A Comparison of Some Methods for Estimation of Potential Evaporation
Methods Estimation Potential Evaporation
2009/10/28
In most of the important agricultural regions of the world, evaporation in the
growing season exceeds the precipitation, and also often the sum of
precipitation and plant available water in the root...
The frequency analysis of flood flows recommended in textbooks yields
different results by the graphical method of plotting on probability paper
using e.g. the Weibull plotting position formula and ...
Estimation of Combined Sewer Overflow Discharge From the City of Malmö
Estimation Combined Sewer Overflow Discharge City of Malmö
2009/10/28
The function of combined sewer overflows (CSO) from both a quantitative
and a qualitative point of view is often little known in the Nordic communities.
Since large pollution loads are discharged fr...
