Modelling field scale water partitioning using on-site observations in sub-Saharan rainfed agriculture
field scale water partitioning on-site observations sub-Saharan rainfed agriculture
2010/4/7
Smallholder rainfed farming systems generally realise sub-optimal crop yields which are largely attributed to dry spell occurrences during crop growth stages. However, through the introduction of appr...

Spatial Variability of Physical Parameters and Processes in Two Field Soils Part Ill:Solute Transport at Field Scale
Spatial Variability Physical Parameters Two Field Soils Field Scale
2009/10/26
A numerical analysis of solute transport in two spatially heterogeneous fields is
carried out assuming that the fields are composed of ensembles of one-dimensional
non-interacting soil columns, each...
APPLICATION OF GEOTECHNOLOGY TO WATERSHED SOIL CONSERVATION PLANNING AT THE FIELD SCALE
Soil conservation planning India mountainous watersheds
2009/10/12
Soil conservation planning in inaccessible mountainous watersheds is a very tedious and expensive job. Generally, in India most soil conservation programs are carried out with physical reconnaissance ...
Comparison of three stream tube models predicting field-scale solute transport
convective lognormat transfer stochastic stream tube solute transport
2009/6/8
In this paper the relation between local- and field-scale solute transport parameters in an unsaturated soil profile is investigated. At two experimental sites, local-scale steady-state solute transp...
Field scale variability of solute transport parameters and related soil properties
convective-dispersive equation mobility index breakthrough curves
2009/6/8
The spatial variability of transport parameters has to be taken into account for a reliable assessment of solute behaviour in natural field soils. Two field sites were studied by collecting 24 and 36 ...
