Studeis on Shallow Infiltration Tube Wells
Abstract
Studeis On Shallow Infiltration Tube Wells Groundwater irrigation is one of the alternative methods to irrigate the paddy crops beside surface water. The use of shallow tube well for paddy irrigation is able to overcome water scarcity especially during dry season and off planting season in Malaysia. The performance of a shallow tube well was evaluated based on well efficiency and pump efficiency. The study was conducted at Seberang Perak Integrated Agricultural Development Area (Seberang Perak IADA). In this study, on-off automatic water controller was installed in the field and connected to the pump system which gave the command to the pump to irrigate the field during pre-saturation and normal growth plantation period.
Conclusion
The performance of groundwater irrigation in term of well efficiency and pump efficiency was studied in this paper. The well efficiency of the pumping well was varied between 91 and 94% and the pump efficiency was 87.5%. The potential well yield of shallow tube well was evaluated as 450 m3day-1 and it was sufcient to irrigate 1 ha of paddy eld by single well with the depth of 11 m from ground surface at Seberang Perak IADA.
