Reservoir Reservoir Capacity Analysis in the USU Kwala Bekala Campus Area: Anticipating Floods and Ensuring Water Resilience

Introduction

The University of North Sumatra (USU) Kwala Bekala campus, located in Pancur Batu District, Deli Serdang Regency, is prone to flooding due to the presence of the Tualang River that flows through the middle of the campus. To mitigate this risk, a reservoir was constructed to control floods and ensure the availability of water for campus activities. This study aims to analyze the reservoir's capacity to handle water discharge and peak flood discharge in the Tualang River, using secondary data including 10-year rainfall data, watershed maps (DAS), and reservoir characteristics.

Background

The Tualang River, which flows through the USU Kwala Bekala campus, poses a significant threat to campus activities due to the potential for flooding. The construction of a reservoir is a crucial step in controlling floods and ensuring the sustainability of water resources for campus activities. However, the reservoir's capacity to handle water discharge and peak flood discharge is a critical factor in determining its effectiveness.

Methodology

This study employed a multi-stage analysis to determine the reservoir's capacity to handle water discharge and peak flood discharge. The analysis stages included:

Analysis of Rainfall Distribution Patterns

Rainfall data were analyzed using normal and logarithmic statistical parameters to understand the pattern of rainfall in the area. This analysis is crucial in determining the reservoir's capacity to handle water discharge and peak flood discharge.

Flood Discharge Analysis

The HSS Nakayasu method was used to analyze flood discharge, considering the 100-year period. This analysis is essential in determining the maximum flood discharge that the reservoir can handle.

Flood Routing Analysis

This analysis was carried out to determine the maximum discharge that came out of the reservoir and estimating the height of the water that passed through the spillway. This analysis is critical in determining the reservoir's capacity to handle peak flood discharge.

Results

The analysis results showed that:

Reservoir Reservoir Capacity

Based on the reservoir topography, a total volume of 780,555.16 m3 was obtained. Water discharge that can be utilized for raw water needs is 14.65 liters/sec for one year.

Peak Flood Discharge

The results of the 100-year flood discharge analysis using the HSS Nakayasu method showed a debit of 71.73 m3/sec. Flood routing analysis shows the maximum discharge that passes through the overflow reaches 15.40 m3/sec on the elevation of 73.50 m.

Height of Religion

Analysis shows the height of a freboard at 0.5 meters.

Conclusion and Recommendations

The results of the analysis showed that the USU Kwala Bekala Campus Reservoir was not safe against runoff of the maximum flood discharge of 100 years. This means that the height of the reservoir embankment needs to be raised at 1.5 meters to ensure the safety of flooding.

Additional Recommendations

River Discharge Monitoring

Periodic river discharge monitoring is very important to anticipate changes in discharge and ensure the effectiveness of reservoirs in flood control.

Socialization and Education

Socialization to the campus community regarding the importance of maintaining the cleanliness and sustainability of the Tualang River and Reservoir River watershed, as well as education about the dangers of flooding.

Development of Flood Early Warning Systems

Development of Flood Early Warning Systems can help in increasing preparedness and minimizing the adverse effects of flooding.

Implementation of Recommendations

By implementing these recommendations, the USU Kwala Bekala Campus Reservoir can be an effective solution in controlling floods and ensuring the sustainability of water resources for campus activities. The reservoir's capacity to handle water discharge and peak flood discharge can be improved by raising the height of the reservoir embankment and implementing river discharge monitoring, socialization, and education, and development of flood early warning systems.

Conclusion

The USU Kwala Bekala Campus Reservoir is a critical infrastructure in controlling floods and ensuring the sustainability of water resources for campus activities. This study has analyzed the reservoir's capacity to handle water discharge and peak flood discharge, and provided recommendations for improving its effectiveness. By implementing these recommendations, the reservoir can be an effective solution in controlling floods and ensuring the sustainability of water resources for campus activities.

Limitations

This study has several limitations, including the use of secondary data and the assumption of a 100-year flood discharge. Future studies should aim to collect primary data and consider other factors that may affect the reservoir's capacity to handle water discharge and peak flood discharge.

Future Research Directions

Future research should aim to:

Improve the accuracy of flood discharge analysis

Future studies should aim to improve the accuracy of flood discharge analysis by considering other factors that may affect the reservoir's capacity to handle water discharge and peak flood discharge.

Develop a more comprehensive flood management plan

Future studies should aim to develop a more comprehensive flood management plan that considers the reservoir's capacity to handle water discharge and peak flood discharge, as well as other factors that may affect the campus's vulnerability to flooding.

Implement flood early warning systems

Future studies should aim to implement flood early warning systems that can help in increasing preparedness and minimizing the adverse effects of flooding.

By addressing these limitations and future research directions, the USU Kwala Bekala Campus Reservoir can be an effective solution in controlling floods and ensuring the sustainability of water resources for campus activities.
