Introduction

Rainfall analysis using rational methods is a crucial approach in hydrology to estimate the volume of rainfall or discharge in various return periods. Estimation of peak discharge with this method requires rainfall data for 22 years to be analyzed gradually. This process starts from statistical parameters, frequency distribution, distribution testing, rainfall design, to intensity calculation (I). By utilizing landscape data and watershed characteristics, we can determine the runoff coefficient (C). These two parameters, namely I and C, are used to determine the peak discharge in the watershed. Understanding the importance of rainfall analysis is essential in the planning and management of water resources, as it helps in designing the drainage system and flood control infrastructure.

The Importance of Rainfall Analysis

Rainfall analysis has a vital role in the planning and management of water resources. By understanding the pattern of rainfall, we can be more effective in designing the drainage system and flood control infrastructure. In the Bahbolon Das area, Simalungun Regency, floods often occur that cause environmental damage and threaten the safety of the community. Therefore, this analysis is very crucial for mitigating the impact of flooding. The consequences of flooding can be devastating, and it is essential to take proactive measures to prevent it. Flood control infrastructure is a critical component in preventing the impact of flooding, and rainfall analysis plays a significant role in designing and implementing effective flood control measures.

Rational Method in Debit Estimation

The rational method is one of the most common techniques used in hydrology to estimate the peak discharge. This method considers the relationship between rainfall, runoff coefficient, and watershed area. In its application, the first step is to gather and analyze rainfall data. After that, statistical parameters such as average and standard deviation of rainfall are analyzed to determine the pattern of distribution. The rational method is a widely used technique in hydrology due to its simplicity and accuracy. However, it requires careful analysis of rainfall data to ensure accurate results.

Data Processing Process

After the rainfall data is collected, the next step is to conduct a distribution test to ensure that the data is in accordance with certain distribution models, such as gumbel distribution or normal log. This test is important for validating the accuracy of the model used. After the appropriate distribution model is determined, the next step is to calculate the rainfall design for various return periods. The accuracy of the results depends on the quality of the data and the model used. Data processing is a critical step in rainfall analysis, and it requires careful attention to detail to ensure accurate results.

Calculation of the Railway Coefficient

The runoff coefficient (C) is an important parameter that shows how much the proportion of rainfall will flow into the river. Determination of the value of C depends on various factors such as the type of land use, the level of building density, and soil characteristics. By combining the values I and C, we can calculate the expected peak discharge in the watershed. The runoff coefficient is a critical parameter in rainfall analysis, and it requires careful consideration of various factors to ensure accurate results.

Benefits of Analysis for the Community and the Environment

The results of this rainfall analysis are not only beneficial for infrastructure planning, but also have a positive impact on the community and the environment. With a good flood control system, losses due to floods can be minimized. In addition, this analysis can also help in formulating a more sustainable water resource management policy, as well as increasing public awareness of the importance of environmental conservation. The benefits of rainfall analysis extend beyond infrastructure planning and have a positive impact on the community and the environment.

Conclusion

Thus, the analysis of rainfall and the estimation of peak discharge using rational methods in the Bahbolon Das, Simalungun Regency, is a strategic step in efforts to control floods and more effective water resources management. Through systematic research and accurate use of data, we can create better solutions to maintain the welfare of the community and the environment. Rainfall analysis is a critical component in water resources management, and it requires careful attention to detail to ensure accurate results.
