Discussion of Results:
The results obtained from the measurements allow us to calculate the stream discharge for both the Kefamo and Mafemo Rivers. For the Kefamo River, the calculated discharge was 145.77 cubic meters per second. This value represents the volume of water flowing through the river per unit of time. For the Mafemo River, the calculated discharge was 604.47 cubic meters per second. This indicates a higher flow rate compared to the Kefamo River. To ensure accuracy in the measurements, a correction factor of 0.85 (85%) was applied to both river discharges. This correction factor accounts for any potential errors in the measurements. After applying the correction factor, the adjusted discharge for the Kefamo River was 123.90 cubic meters per second, while the adjusted discharge for the Mafemo River was 513.80 cubic meters per second.
The results of the measurements and calculations indicate that the Mapemo River has a higher stream discharge compared to the Kefamo River. This suggests that the Mapemo River carries a larger volume of water and has a greater flow rate.
It is important to measure and understand stream discharge as it provides valuable information for various practical applications. Knowing the stream discharge helps in assessing water availability, flood forecasting, water resource management, and designing infrastructure such as bridges and dams.
Additionally, measuring the physical and chemical parameters of the stream, such as dissolved oxygen, pH, color, turbidity, and conductivity, provides further insights into the health and characteristics of the water body. These parameters help in evaluating water quality, assessing aquatic ecosystem health, and monitoring any potential pollution or contamination.
The measurements and calculations of the stream discharge for the Kefamo and Mafemo Rivers provide valuable information about their flow rates and water volumes. Understanding these parameters is crucial for various practical applications and for monitoring the health and quality of the water bodies.
Conclusion:
Based on the measurements and calculations obtained during the field trip, we were able to determine the discharged cross-sectional area and mean velocity of the stream. By repeating the procedure multiple times and recording the time it took for the float to travel the marked section, we were able to obtain accurate data.
Our key findings for Kefamo and Mafemo River revealed that the stream had an average depth of 3.065cm and 64.58 cm and a width of 41meters and 9 meters. The mean velocity of the stream was calculated to be 1.16 meter and 1.04 meters per second.
Overall, the field trip objectives were successfully achieved. We were able to gather the necessary data to analyse and understand the stream’s characteristics.
Recommendations:
Positives: The use of various sensors (dissolved oxygen, pH, colorimeter, turbidity, and conductivity) provided a comprehensive understanding of the stream’s water quality.
The inclusion of a weather sensor and tablet allowed for real-time tracking of weather conditions during the measurements. Negatives use of a lemon as a floating device may not have provided the most accurate results. It is recommended to use a more standardized and precise floating device, such as a dedicated stadia rod. The field trip procedure could have benefited from more detailed instructions and guidance on data collection and calculations.
Suggestions for Improvement- Provide more training and guidance on the use of equipment and data collection procedures. Consider using more advanced technology, such as drones or remote sensing, to gather data from a larger area of the stream. Incorporate a larger sample size and more repetition of measurements to ensure accurate and reliable results. Involve more interactive activities or demonstrations to further engage students and enhance their understanding of stream dynamics.

Introduction:
Streamflow and discharge are important parameters to measure and understand in order to assess the health and characteristics of a stream or river. In addition, conducting physiochemical parameter tests on streams and rivers provides valuable information about water quality and potential contamination. The objective of this field trip was to measure and calculate the stream discharge for the Kefamo and Mafemo Rivers, as well as collect data on various physiochemical parameters to evaluate water quality.
The research questions for this field trip were: What is the stream discharge for the Kefamo and Mafemo Rivers? How do these rivers compare in terms of flow rate and water volume? What are the physiochemical characteristics of the water bodies and what insights can be gained from these measurements?
The purpose of the field trip was to gather data and analyze the characteristics of the two rivers, specifically their flow rates, water volumes, and water quality. By measuring the stream discharge and conducting physiochemical parameter tests, we aimed to gain a better understanding of these water bodies and their potential impacts on surrounding ecosystems and communities.
The importance of this field trip lies in the practical applications of the data collected. Measuring stream discharge helps assess water availability, monitor flood risks, manage water resources, and design infrastructure. Understanding the physiochemical parameters of the water can provide valuable insights into water quality, ecosystem health, and pollution levels.
However, it is important to acknowledge the limitations and setbacks experienced during the field trip. The use of a lemon as a floating device may have introduced some inaccuracies in the measurements. It would be recommended to use a more standardized and precise floating device, such as a dedicated stadia rod. In addition, the field trip procedure could have benefited from more detailed instructions and guidance on data collection and calculations.
Despite these limitations, the field trip successfully achieved its objectives of gathering data on stream discharge and physiochemical parameters. The results obtained provide valuable information about the characteristics and health of the Kefamo and Mafemo Rivers, contributing to our understanding of these water bodies and their potential impacts on the environment and communities.
