Abstract

Drainage of excess precipitatio, stream water and soil ground water as meliorative measure belongs to an important water management measures in areas affected by unfavorable climatic conditions. In the area City of Slavonski Brod in the Brod-Posavina County, research of the precipitation impact on the water flow in the eastern lateral canal "Jelas polje" was done. The aim of this work was monitoring of daily precipitation for three months (February, March, April, 2022) to determine its impact on the wetted surface (Op) and t he water flow volume (Pv) in the lateral canal. Monitoring excess water in the cannel network of the drainage system can be a good indicator of the efficiency of the drainage system, its influence on the slopes of the cannel and can have positive effects on the yield of agricultural crops. The highest water flow volume during this research was 744.33 m3 h-1, while the lowest was 33.71 m3 h-1. The lowest water velocity of 0.57 m s-1 was recorded at the same time as the lowest water flow volume. Based on the collected data, it can be concluded that the cannel and its slopes are well hydraulically designed. Also considering the collected water that affects the wetted surface and the water flow volume, there is no significant increase on the speed of water, which can unfavorable affect the cannel slopes.
