Introduction

The drainage system in irrigation areas is a crucial element in accommodating water runoff and preventing flooding. Inadequate drainage channels can lead to inundation and flooding, causing significant damage to crops, infrastructure, and the environment. The Singosari irrigation area in Serdang Bedagai Regency is no exception, with frequent flooding events occurring due to the inability of the drainage system to accommodate excess water discharge. This study aims to evaluate the drainage system in the Singosari irrigation area, identify the causes of flooding, and provide recommendations for improvement.

The Importance of Drainage System Evaluation

The evaluation of the drainage system in irrigation areas is essential to determine the capacity of the drainage channel and predict the potential for flooding. By analyzing rainfall data and land use, we can identify the factors that contribute to flooding and take the necessary steps to prevent it. The rational method and mononobe method are commonly used to calculate flood discharge based on rainfall intensity, watershed area, and runoff coefficient. However, these methods have limitations, such as not taking into account the time of concentration and other hydrological factors.

Rational Method

The rational method is a simple method for calculating flood discharge based on rainfall intensity, watershed area, and runoff coefficient. This method is useful for the initial planning of the drainage system, but it has several limitations, such as not taking into account the time of concentration and other hydrological factors. The rational method is often used in conjunction with other methods, such as the mononobe method, to provide a more accurate estimate of flood discharge.

Mononobe Method

The mononobe method is used to change daily rainfall data into an hourly rainfall intensity. This method is important because the intensity of rainfall per hour is more relevant in drainage system planning. The mononobe method takes into account the time of concentration, which is the time it takes for water to flow from the watershed to the drainage channel. This method is more accurate than the rational method, but it requires more data and computational resources.

Changes in Land Use and Their Impact on Flood Discharge

Changes in land use, such as land clearing, infrastructure development, and land conversion, have a direct impact on flood discharge. A waterproof surface, such as concrete, reduces water infiltration to the ground, thereby increasing flood runoff and discharge. The increased runoff and discharge can lead to flooding, especially in areas with inadequate drainage channels.

Limitations of Drainage Channels

Inadequate drainage channels in terms of size and capacity, as well as sedimentation or blockage, can cause a decrease in the ability of the canal to accommodate flood discharge. Sedimentation and blockage can occur due to the accumulation of sediment, debris, and other materials in the drainage channel. This can reduce the capacity of the channel and increase the risk of flooding.

Solutions and Recommendations

To improve the drainage system in the Singosari irrigation area, several solutions and recommendations can be implemented.

Increasing the Capacity of the Drainage Channel

The capacity of the drainage channel may need to be expanded by increasing the size of the channel, cleaning sedimentation, and repairing channel structures. This can be achieved through the construction of new drainage channels, the upgrading of existing channels, and the implementation of sedimentation control measures.

Improvement of Water Management Systems

The application of efficient irrigation systems and good water management can minimize runoff and reduce loads in the drainage system. This can be achieved through the implementation of water-saving technologies, the use of efficient irrigation methods, and the implementation of water conservation measures.

Development of Flood Early Warning Systems

The development of flood early warning systems can help the community to prepare for flooding and reduce their impact. This can be achieved through the installation of flood warning systems, the implementation of emergency response plans, and the provision of education and training to the community.

Increasing Public Awareness

Education and socialization to the public about the importance of maintaining environmental cleanliness and drainage channels can help in maintaining the performance of the drainage system and preventing flooding. This can be achieved through the implementation of public awareness campaigns, the provision of education and training to the community, and the involvement of local stakeholders in the management of the drainage system.

Conclusion

The evaluation of the drainage system in the Singosari irrigation area is an important step to prevent flooding and maintain the smooth irrigation system. By analyzing rainfall data, changes in land use, and evaluating the capacity of the drainage channel, we can take the right steps to overcome the potential for flooding in the region. The solutions and recommendations provided in this study can be implemented to improve the drainage system and reduce the risk of flooding.

Recommendations for Future Research

Future research should focus on the development of more accurate and reliable methods for calculating flood discharge, the implementation of more effective sedimentation control measures, and the development of more efficient irrigation systems. Additionally, research should be conducted on the impact of climate change on flood discharge and the development of more effective flood early warning systems.
