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.

Levees are specialized embankments or earthen barriers that are built along rivers, lakes, and other bodies of water to prevent floods and protect adjacent areas from water damage. This work requires specialized engineering and construction skills, including knowledge of soil mechanics, hydrology, and geotechnical engineering. In addition, levee construction often involves coordinating with local government agencies, environmental groups, and other stakeholders to ensure that the resulting structure is safe, effective, and environmentally sound.

Sediment Transport refers to the movement of solid particles, typically soil and rock, from one location to another by natural forces such as water, wind, or ice. This skill encompasses the understanding of the processes and mechanisms that govern sediment movement, including erosion, deposition, and sedimentation. Knowledge of Sediment Transport is used to analyze and predict changes in landscapes, manage river systems, and inform construction and environmental projects by assessing sediment dynamics and their impact on ecosystems.

Spillway refers to a structure designed to manage excess water flow from a dam or reservoir, ensuring controlled release to prevent overflow and potential flooding. This skill encompasses the design, construction, and maintenance of spillways, which are critical for maintaining water levels and protecting surrounding areas. Knowledge of Spillway is used to assess hydraulic performance, implement safety measures, and optimize water management strategies in various hydrological contexts.

Water Resources refers to the management and allocation of water supply for various uses, including agricultural, industrial, and domestic purposes. This skill encompasses the understanding of hydrology, water quality, and environmental impacts, enabling effective planning and sustainable use of water systems. Knowledge of Water Resources is used to develop strategies for water conservation, flood control, and the protection of aquatic ecosystems, ensuring the availability of clean water for current and future generations.
