The student precisely described the methods selected for both primary and secondary data collection, detailing techniques such as stratified sampling and specific measurement methods for velocity, width, depth, and bedload size. The chosen methods were effectively justified, highlighting their accuracy and the rationale behind minimizing bias in data collection. The student selected suitable techniques to ensure quality data for analysis, employing both the orange method and flowmeter for velocity measurements. Furthermore, the student stated the date, time, and location of data collection, and included necessary figures to illustrate the methods used in the investigation. Overall, the student demonstrated a thorough understanding of the methodological framework for the investigation.
