Analysis of Potential Water Supply and Flood Vulnerability in Subdas Sei Bingei and Sei Sending to Flood Disaster Mitigation

Introduction

The river is a vital water resource that provides numerous benefits for human life, including drinking water, irrigation, and hydroelectric power. However, excess rainfall can cause flooding, which occurs when the river or water body overflows, resulting in devastating consequences for communities and the environment. This study aims to analyze areas that are vulnerable to flooding and potential water supply in the Wampu Sei Sendas Sendas River Basin (DAS) Sei Sendas and Subdas Sei Bingei, with a focus on flood disaster mitigation strategies.

Background

The Wampu Sei Sendas Sendas River Basin (DAS) Sei Sendas and Subdas Sei Bingei is a critical water resource that supports the livelihoods of many communities. However, the area is prone to flooding, which can have severe consequences for the environment and human settlements. The study area is characterized by four types of land systems and three types of landforms, which are identified as follows:

Land Systems: The study area is divided into four types of land systems, including:
- Alluvial plains and alluvial valleys
- Mountainous areas and hills
- Coastal areas and deltas
- Upland areas and plateaus
Landforms: The study area is characterized by three types of landforms, including:
- Alluvial plains and alluvial valleys
- Mountainous areas and hills
- Coastal areas and deltas

Methodology

The study used a combination of remote sensing and field observations to analyze the land cover and land use patterns in the study area. The Sentinel 2-A image analysis was used to identify five types of land cover, including:

Vegetation: Forests, grasslands, and shrublands
Agriculture: Croplands, orchards, and plantations
Water: Rivers, lakes, and wetlands
Built-up areas: Urban and rural settlements
Barren land: Bare soil, rocks, and sand

The study also analyzed the rainfall data for the five-year period (2016-2020) to identify the average daily maximum rainfall and its relationship with the land cover and land use patterns.

Results

The results of the study showed that the area with the highest level of vulnerability to flooding is the alluvial plains and alluvial valleys. The geological characteristics of these two types of land make it very difficult to absorb water, considering that it is generally downstream of the river. On the other hand, mountainous areas and hills have a large potential to be a water supplier that causes flooding. This is caused by the high rainfall intensity and geographical position in the upstream of the river, where the water from the rain flows down to the lower area.

Discussion

The study highlights the importance of flood mitigation strategies in the Wampu Sei Sendas Sendas River Basin (DAS) Sei Sendas and Subdas Sei Bingei. The results of the study suggest that increasing water interception by planting conservation plants, such as banyan, cempedak, and bamboo, can help reduce the speed of water flow and improve the quality of the soil. Additionally, increasing soil infiltration through making reservoirs or reservoirs, as well as making biopori holes, can help accommodate excessive rainwater, thereby reducing the possibility of flooding.

Conclusion

The study concludes that the Wampu Sei Sendas Sendas River Basin (DAS) Sei Sendas and Subdas Sei Bingei is a critical water resource that requires careful management to mitigate the effects of flooding. The study highlights the importance of flood mitigation strategies, including increasing water interception and soil infiltration, to protect the community and the environment from the adverse effects of flooding. It is essential for stakeholders to work together in implementing this strategy for the sustainability of water resources and community safety.

Recommendations

Based on the findings of the study, the following recommendations are made:

Increase water interception: Planting conservation plants, such as banyan, cempedak, and bamboo, can help reduce the speed of water flow and improve the quality of the soil.
Increase soil infiltration: Making reservoirs or reservoirs, as well as making biopori holes, can help accommodate excessive rainwater, thereby reducing the possibility of flooding.
Implement flood mitigation strategies: Stakeholders should work together to implement flood mitigation strategies, including increasing water interception and soil infiltration, to protect the community and the environment from the adverse effects of flooding.

Limitations

The study has several limitations, including:

Data availability: The study relied on secondary data, which may not be comprehensive or up-to-date.
Methodological limitations: The study used a combination of remote sensing and field observations, which may not be sufficient to capture the complexity of the study area.
Scalability: The study was conducted at a small scale, and its findings may not be applicable to larger areas.

Future Research Directions

The study highlights several areas for future research, including:

Flood modeling: Developing flood models that can simulate the effects of flooding in the Wampu Sei Sendas Sendas River Basin (DAS) Sei Sendas and Subdas Sei Bingei.
Flood mitigation strategies: Evaluating the effectiveness of flood mitigation strategies, including increasing water interception and soil infiltration, in reducing the effects of flooding.
Community engagement: Engaging with local communities to raise awareness about the importance of flood mitigation strategies and involving them in the decision-making process.
