Abstract :

The aim of the research is to design suitable basin irrigation system for the downstream of Girei earth dam, for efficient use of the available water for the dry season farming activities. An effective irrigation system requires the determination of the slope of the field, the infiltration rate of the soil and the textural classification of the soil. All these parameters were used to design the basin irrigation for the downstream of Girei earth dam. The percentages of sand, silt and clay were determined using the hydrometer method and the result was found to be 78.4%, 5.2% and 16.4% respectively. The textural triangular chart was used to interpret the result which showed that the soil is a sandy loam soil which is suitable for irrigation of rice farming. The double ring infiltrometer was used to determine the soil infiltration rate and result shows the moderate intake rate of the soil. The infiltration rate was 7.72 mm/min. The slope of the area was determined using the grid method of leveling and was found to be 0.0017 which is suitable for basin irrigation system. A trapezoidal channel was design based on the slope and soil type in the research area.
