Erosions refers to the process of wearing away soil, rock, or other materials from the Earth's surface due to natural forces such as water, wind, and ice. This skill encompasses the understanding of the mechanisms and factors that contribute to erosion, as well as the assessment of its impact on landscapes and ecosystems. Knowledge of Erosions is used to develop strategies for soil conservation, land management, and environmental protection by mitigating the effects of erosion and promoting sustainable practices.

Sanitary Sewer refers to a system designed to transport wastewater and sewage from residential, commercial, and industrial sources to treatment facilities. This skill encompasses knowledge of the design, construction, and maintenance of sewer systems, ensuring the safe and efficient removal of waste to protect public health and the environment. Understanding Sanitary Sewer systems is used to assess infrastructure needs, implement effective waste management strategies, and address potential issues such as blockages or leaks.

Sediment Controls refer to practices and techniques designed to prevent sediment from leaving a construction site and entering nearby water bodies. This skill encompasses the implementation of barriers, filters, and other methods to manage soil erosion and sedimentation during land disturbance activities. Knowledge of Sediment Controls is used to ensure compliance with environmental regulations and to protect water quality by effectively managing runoff and minimizing the impact of construction activities on the surrounding ecosystem.

Stormwater management is an engineering practice focused on managing and mitigating the effects of rainfall and other natural water sources. This involves designing systems and techniques to manage stormwater runoff, improve water quality, and prevent flooding. It requires specialized knowledge in hydrology, engineering, and environmental science. Effective stormwater management is critical for maintaining the ecological health of our waterways and protecting public safety and property.

Stream restoration involves the application of specialized skills and techniques to improve the health and functionality of degraded or damaged streams. This may include activities such as stabilizing stream banks, restoring natural flow patterns, and reintroducing native vegetation and aquatic species. It requires expertise in hydrology, geomorphology, ecology, and engineering, as well as knowledge of local regulations and permitting requirements. Stream restoration is typically undertaken in partnership with stakeholders such as landowners, community groups, and government agencies.
