Free downloads of software
The site gives free download opportunity of software and models
freeware and computer programs (tools I developed because of need in my work).
The programs relate to statistics (segmented linear regression with break-point,
cumulative frequency analysis and recurrence predictions), groundwater flow to subsurface drains
(horizontal/tile drainage) and pumped tubewells (vertical drainage), rainfall-surface runoff relations
simulated with a nonlinear reservoir, and agro-hydro-salinity simulation models including
groundwater hydraulics in unconfined and semiconfined aquifers.
See further down for more information
Free downloads of general articles
The site offers free downloading of general articles and manuals
in the field of waterlogging, agricultural land drainage for soil desalination (desalinization),
salty soils, and subsurface drainage for agriculture (horizontal and vertical).
In addition one can find here supporting papers on the software referring to land reclamation
(rehabilitation) of waterlogged land, and the remediation (restoration) of salt affected, saline,
soils. The same holds for the models on statistical analysis, segmented linear regression of plant
growth, crop production and yield responses, as well as cumulative frequency distributions of
Reports and case studies
A list of project evaluations and case studies on water-management, agricultural land drainage,
irrigation, drainage for salinity control in agriculture for remediation of soil salination
(salinisation) can be found on the published reports page and on the
particular reports page.
The same holds for reclamation, rehabilitation, restoration and improvement of salty, saline,
alkaline and acid sulphate/sulfate soils
Answers to frequently asked questions
Frequently asked questions, often on irrigation, soil salinity, alkalinity and acidity (i.e.
saline, salty, alkali, alkaline sodic and acid sulphate/sulfate soils), land rehabilitation and
remediation are answered on the
with papers and lecture notes.
Further, one may find here the answers to questions on the selection of land drainage systems in
agriculture, on the determination of hydraulic conductivity, on interception drainage, on subsurface
drains in sloping land, and on downstream river salinity.
I intend to update and expand this website regularly and include
