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
The source code of the software can be seen at the
open source page.
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 hydrologic factors.
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
page and on the
The same holds for reclamation, rehabilitation,
restoration and improvement of salty, saline,
alkaline and acid sulphate/sulfate soils.
I intend to update and expand this website
