Soil Characterization and Modeling of Spatial Distribution of Saturated Hydraulic Conductivity at Two Sites in the Volta Basin of Ghana
Author: Wilson Agyei AgyarePublisher: Cuvillier Verlag
ISBN: 3865371000
Category : Hydraulics
Languages : en
Pages : 211
Book Description
One of the key parameters in hydrological and climate change modeling is a good estimation of the soil hydrauic properties in the region of interest. This study investigates the spatial distribution and variability of soil physical properties, with emphasis on saturated hydraulic conductivity at two pilot sites in the Volta Basin of Ghana. It focuses on the potential of pedotransfer functions (PTFs) and artificial neural network (ANN) approach for estimating saturated hydraulic conductivity. Saturated hydraulic conductivity was observed to be highly spatially variable; however, it can be estimated using selected PTFs and ANN for soils in the Volta Basin based on soil parameters that can readily be obtained from detailed soil maps--From cover.

Surface Runoff and Infiltration Processes in the Volta Basin, West Africa

ISBN: 3865370977
Category : Hydraulics
Languages : en
Pages : 157
Book Description
"The study presents the analyses of field observations and simulation experiments with an event-based, two-dimensional hydrodynamic model. The model summarized the interactions between temporally dynamic rainfall, infiltration process and surface runoff in a catchment with varied soil physio-hydraulic properties, surface-roughtness, slope-lengths and vegetation structure. Both observation and simulation results indicate that the observation scale affects runoff coefficient and runoff discharge per unit area. The effect of scale is a result of spatial variability in infiltration opportunities, which vary with the slop length and distribution of saturated conductivity, leading to different trasmission losses potential during runoff routing downslope. The magnitude of the difference is influenced by surface and vegetated microtopography, which determine the flow rate"--Back cover.

The Spatial Distribution of Soil Salinity

Book Description
Soils of irrigated lands in the Aral Sea Basin are often plagued by high salinity,hampering profitable agriculture on these soils. In this context, the present study has three specific objectives: to identify techniques that enable a rapid estimation of soil salinity, to characterize its spatial distribution and to estimate its spatial distribution based on readily obtainable environmental parametersusing a Neural Network Model Approach. Topsoil salinity was highly variable atshort distances and terrain attributes were the most influential factors. The use of relationships between environmental attributes and soil salinity for upscaling spatial distribution of soil salinity from farm to district level proved to be satisfactory. A possible application is the development of salinity prediction toolsfor farm-level decision making.
