Abstract

Rivers play a crucial role in ecosystems and human life. Accurate understanding of hydraulic characteristics, such as flow velocity and discharge, is essential for sustainable water resource management, flood mitigation, infrastructure planning, and aquatic ecological studies. To comparatively examine the hydraulic characteristics of a river, this study was conducted on a micro scale using the float method, with simulations performed on the Toladan River.The research was carried out in the Toladan River Watershed (TRW) located in Jayapura Regency, mapped on a small scale and divided into three observation points, with a total observation area of approximately 514.75 m².Measurements were conducted using the float method, with the floating object being a cardboard box measuring 4 cm × 3 cm × 2 cm. The data collected consisted of the travel time of the water flow, which was used to calculate flow velocity and discharge. The results showed that the highest flow velocity was recorded at the first observation point at 0.367 m/s, followed by the second point at 0.331 m/s, and the third point at 0.148 m/s. In contrast, the highest discharge was observed at the third point, reaching 0.654 m³/s, followed by the second point at 0.448 m³/s, and the lowest at the first point with 0.382 m³/s. These findings indicate a linear relationship between flow velocity and discharge, influenced by the cross-sectional area of the stream: lower flow velocity with higher discharge suggests a wider cross-sectional area. The results also show that discharge in the Toladan River is not constant and that flow velocity is affected by watershed size, river depth, and watershed slope.

Abstract

The Toladan River, located in Jayapura Regency, Papua, offers promising opportunities for renewable energy development, particularly small-scale micro-hydropower systems. Accurate estimation of dependable flow is essential for determining hydropower feasibility and sustainable energy planning. This study analyzes the dependable flows of the Toladan River using field-based discharge measurements from three observation points and employing a flow-duration-curve (FDC) statistical approach. Discharge measurements were obtained using the float method, supported by cross-sectional geometry assessments at each site. Results show that average discharges at the three observation points were 0.382 m³/s, 0.448 m³/s, and 0.654 m³/s, respectively, reflecting significant variations in channel dimensions. These values were statistically processed to estimate dependable flow rates at exceedance levels of Q50, Q70, and Q90. The analysis indicates that Q90 dependable discharge remains adequate for small-scale micro-hydropower development. Overall, this study demonstrates that the Toladan River provides a stable flow regime conducive to micro-hydropower generation, offering essential baseline data to support renewable energy planning in Papua
