Biochemical Oxygen Demand" is an essential educational resource tailored for environmental science and engineering students, aiming to deepen their understanding of water quality assessment and pollution control. This unit comprises a series of engaging lessons, each meticulously designed to explore the dynamics of Biological Oxygen Demand (BOD) and its implications for aquatic ecosystems.Beginning with foundational concepts of dissolved oxygen and BOD, learners progress to advanced topics such as the Dissolved Oxygen Model and SAG (Submerged Aquatic Growth) curve analysis. Through interactive discussions and problem-solving exercises, students develop proficiency in calculating key parameters related to water quality, including DO concentrations and BOD levels.
Students build a watershed model to define what a watershed is, identify the different parts within a watershed, and discover how water moves within a watershed. After learning Best Management Practices and mitigation techniques, students rebuild their models.
