From the Integrating Mathematical Problem Solving project by Mathematics in Education and Industry (MEI), this activity for post-16 students demonstrates that the efficiency of a river can be measured using the hydraulic radius; this depends on the cross-sectional area of the river and the wetted perimeter of the cross-section. Topic areas covered are:
• Area
• Perimeter
• Spearman's rank correlation coefficient
• Statistical hypothesis testing
