Estimation of aquifer hydraulic characteristics from electrical sounding data: the case of middle Imo River basin aquifers, south- eastern Nigeria
Aquifer hydraulic characteristics Dar - Zarrouk parameters
2015/8/11
We have used the concept of Da - Zarrouk parameters (transverse unit resistance (R) and longitudinal conductance (C)) in porous media to determine aquifer hydraulic characteristics within the middle I...
Assessment of the Impact pf Mining on Agricultural Land using Erosion-Deposition Model and Space Borne Multispectral Data
Mining Agricultural Land Erosion-Deposition Model Space Borne Multispectral Data
2015/8/6
Since erosion of mine overburden and mine dump leads to its deposition down the slope in the catchment, an attempt was made to study the erosion-deposition pattern in a micro watershed in part of Goa ...
Case Studies of Applying Urban Surface Data in Evaluating Stormwater Management Issues
Urban runoff impervious surfaces suspended solids
2015/1/7
Pollutant load estimation is often required to evaluate stormwater management issues associated with water quality and urban development. Land use (e.g. residential, commercial) is commonly employed a...
The Selection of Narrow Wavebands for Optimizing Water Quality Monitoring on the Great Miami River, Ohio using Hyperspectral Remote Sensor Data
remote sensing hyperspectral chlorophyll turbidity
2014/11/12
Remote sensing data were successfully used to estimate spatial and temporal variation of optical
water quality parameters such as chlorophyll a, turbidity and Total Suspended Solids (TSS) of
the Gre...
Data-based mechanistic modelling and forecasting of hydrological systems
Data-based mechanistic modelling forecasting hydrological systems
2009/12/7
The paper presents a data-driven approach to the modelling and forecasting of hydrological systems based on nonlinear time-series analysis. Time varying parameters are estimated using a combined Kalma...
Subsymbolic methods for data mining in hydraulic engineering
Subsymbolic methods data mining hydraulic engineering
2009/12/7
This paper describes the results of experiments with artificial neural networks (ANNs) and genetic programming (GP) applied to some problems of data mining. It is shown how these subsymbolic methods c...
Managing temporal data in a comprehensive modeling environment
Managing temporal data comprehensive modeling environment
2009/12/7
Numerous graphical pre- and post-processors have been developed for numerical modeling. Many of these systems support numerical models that can be used for both steady state and transient simulations....
Fuzzy mapping of momentum fluxes in complex shear flows with limited data
Fuzzy mapping momentum fluxes complex shear flows limited data
2009/12/4
This study is divided into three parts centred around modelling the complex turbulent fluxes across strong shear layers, such as exist between the channel and floodplain flow in an over bank flood flo...
The physical components of catchments that are commonly included in deterministic
rainfall-runoff models are examined. Data are presented which can be
used for design purposes, to provide a guide to...
Land Use Planning in Denmark:The Use of Soil Physical Data in Irrigation Planning
Land Use Planning Soil Physical Data Irrigation Planning
2009/10/28
The present paper deals with a model developed and used at the Danish
Ministry of Agriculture, Bureau of Land Data, for calculation of the amount
of water needed for irrigation. The model incorporat...
Simulation of Discharge using Different Methods of Meteorological Data Distribution,Basin Discretization and Snow Modelling
Simulation of Discharge Meteorological Data Basin Discretization Snow Modelling
2009/10/26
This contribution investigates the performance of discharge modelling when
proceeding from rather simple methods of snowmelt modelling to more sophisticated,
distributed approaches. In all cases, th...
Inter-Comparison of two Snow Models with Different Complexity using Data from an Alpine Site
Inter-Comparison Snow Models Alpine Site
2009/10/22
This contribution describes the modelization of the snow cover evolution with the two physically based snow models CROCUS and ESCIMO at the Col de Porte station (1,325 m a.s.l., French Alps) for the ...
