Flash-flood forecasting by means of neural networks and nearest neighbour approach–a comparative study
Flash-flood forecasting neural networks nearest neighbour approach
2009/11/9
In this paper, Multi-Layer Perceptron and Radial-Basis Function Neural Networks, along with the Nearest Neighbour approach and linear regression are utilized for flash-flood forecasting in the mountai...
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...
Determination of Anisotropy of Tills by Means of Azimuthal Resistivity and Conductivity Measurements
Determination of Anisotropy Means of Azimuthal Resistivity Conductivity Measurements
2009/10/23
Anisotropy of glacial tills in Lapland revealed with azimuthal galvanic (Terrameter 300 C) resistivity and inductive (Geonics EM-31) electrical conductivity measurements, which were carried out at fou...
Estimation of actual evapotranspiration of Mediterranean perennial crops by means of remote-sensing based surface energy balance models
evapotranspiration surface energy balance Mediterranean perennial crops
2009/7/22
Actual evapotranspiration from typical Mediterranean crops has been assessed in a Sicilian study area by using surface energy balance (SEB) and soil-water balance models. Both modelling approaches us...
Evaluation of 1-D tracer concentration profile in a small river by means of Multi-Layer Perceptron Neural Networks
1-D tracer concentration profile small river Multi-Layer Perceptron Neural Networks
2009/5/13
The prediction of temporal concentration profiles of a transported pollutant in a river is still a subject of ongoing research efforts worldwide. The present paper is aimed at studying the possibility...
Assessing winter storm flow generation by means of permeability of the lithology and dominating runoff production processes
winter storm flow coefficients permeability of the lithology runoff production processes
2009/5/13
In this study two approaches are used to predict winter storm flow coefficients in meso-scale basins (10 km² to 1000 km²) with a view to regionalization. The winter storm flow coefficient co...
Exploratory data analysis and clustering of multivariate spatial hydrogeological data by means of GEO3DSOM, a variant of Kohonen's Self-Organizing Map
self-organizing map Exploratory data analysis
2009/5/8
The use of unsupervised artificial neural network techniques like the self-organizing map (SOM) algorithm has proven to be a useful tool in exploratory data analysis and clustering of multivariate dat...
Estimating the suspended sediment yield in a river network by means of geomorphic parameters and regression relationships
suspended sediment yield geomorphic parameters
2009/4/28
An application of regression relationships depending on geomorphic parameters is proposed to predict the amount of the average annual suspended sediment yield at different sections of the drainage net...
