| Abstract | This study attempts to develop a methodology for assessing the environmental
impacts in large irrigation systems. The Thamaka sub-project, part of the Mae Klong
irrigation project, in Thailand has been taken as the project under consideration.
Drainage water quality, ground water table, ground water quality, water-borne
diseases and soil parameters were selected for intensive study. Selected parameters
were analyzed using chemical analysis and Geographic Information System (GIS).
Vector based thematic maps on the impact parameters were developed by digitizing
existing maps and information and the same were analyzed to detect any impacts on the
environment.
In addition a computer program was written to assess the environmental impacts
on the basis of water balance model and the same was applied to the study area and it
indicates that the most of the environmental impacts of the system studied are due to
excessive water supply.
From the intensive study it can be concluded that the large irrigation systems
over a period of time causes impacts on environment which could vary from system to
system and also within the system from location to location.
The methodology used in this study could be used to study the impacts on
environment in large irrigation systems and could be a useful tool for monitoring and
evaluation of irrigation systems. |
