Abstract:

This study presents a range of drain spacing for the drainage system design in Gbely Meadows located nearby the border of Czech Republic in South Moravia, using selected hydraulic method. The method based on suitable theory to determine drain spacing (L). The boundary condition in selected area collected from previous study of Štibinger et al. (2015), which is conducted in the same location and area with pond created as an outlet. Hooghoudts equation is one of the most common and widely used method for homogenous soil, and will be suitable for this study. Situated in the line of Morava River, Gbely Meadows has suffer enough from waterlogging. Subsurface drainage combined with ditches will be one of the solution to help the local farmers, fight against waterlogging and failed crop. Due to temperature increase, which could lead to dry period together with limited amount of water and low precipitation. An integrated drainage system and irrigation was designed. To cover high rate of evapotranspiration, the area require input water flow to keep water table at some point below the surface soil. According to the previous study of Štibinger et al. (2015), a brook located nearby selected area which has outflow water 3 m3/s. After calculation using irrigation formula, it is sufficient enough to irrigate the selected area and develop an irrigation network integrated with drainage system. A recommendation could be provided in the end of the study to introduce the farmers an effective yet efficient integrated system, to help reduce the waterlogging.
