Introduction

The Krueng Aceh River, located in Lampulo District, Banda Aceh City, Aceh Province, plays a vital role in the lives of the people living in the surrounding areas. As a major drainage flow, it serves as a means of transportation and a source of electricity raw materials. However, the river's existence is not without its challenges. When the river experiences a blockage, the flow of water becomes hampered, leading to flooding. One of the primary causes of flooding is the deposition of sedimentation in the river, which can result in river siltation and reduce the depth of water flow. If this silting exceeds the depth of the river, the flow of water can be broken, increasing the risk of flooding.

The study of sediment content in the mouth of the Krueng River Aceh is crucial in understanding the impact of sedimentation on river flow. The research aims to determine the rate of sediment transport in the river using various methods, including Engelund and Hansen, Yang's, Shen and Hung, and Laursen. Each method requires specific data, including river geometry and sediment characteristics obtained through laboratory analysis.

The Importance of River Management

Rivers play a vital role in the ecosystem, supporting economic life and functioning as a regulator of ecosystems. However, when rivers experience blockages, the flow of water becomes hampered, leading to flooding. The deposition of sedimentation in the river is one of the primary causes of flooding, which can result in river siltation and reduce the depth of water flow. If this silting exceeds the depth of the river, the flow of water can be broken, increasing the risk of flooding.

The study of sediment content in the mouth of the Krueng River Aceh is essential in understanding the impact of sedimentation on river flow. Knowledge of sediment content can help in the management of water resources, as well as disaster prevention efforts such as flooding. Therefore, sustainable management of watersheds is the key to maintaining the balance of ecosystems and preventing adverse natural disasters.

Methodology

The researchers used several methods to determine the rate of sediment transport in the Krueng Aceh River. The methods used include Engelund and Hansen, Yang's, Shen and Hung, and Laursen. Each method requires specific data, including river geometry and sediment characteristics obtained through laboratory analysis.

The calculation results indicate that the sediment charge using the Engelund and Hansen method reaches 832,089.66 tons, the Yang's method 652,263.81 tons, the Shen and Hung 2,819,915 ton method, and the Laursen 815,014.80 ton method for 2007. Based on the analysis, it can be concluded that the most accurate method for the calculation of sediment content in the Krueng Aceh River is the Engelund and Hansen method.
