Analisis Hidrometri Dengan Variasi Metode Pengukuran Pada Aliran Sungai Air Hitam
ABSTRACT
This study aims to analyze hydrometric parameters in the Air Hitam River by comparing two commonly used measurement methods: the float method and the current meter method. Both methods are employed to measure flow discharge and water velocity along the river, which exhibits variations in flow due to natural factors and human activities. The float method tracks the time taken by a float to travel a specific distance across the flow surface, while the current meter method directly measures the water velocity at specific depths using a flow velocity instrument. Measurements were taken at several observation points along the Air Hitam River over a defined period, focusing on depth, flow velocity, and discharge at each point. The results show discrepancies between the two methods in terms of accuracy and reliability, with the current meter method yielding more precise and stable results in varying flow conditions, whereas the float method proved more effective under simpler flow conditions. Statistical analysis indicates that, despite each method's strengths and limitations, a combination of both methods can enhance the accuracy of hydrometric monitoring in rivers. This study is expected to provide valuable insights for the planning and management of water resources in the Air Hitam River and its surrounding areas.
