Green Infrastructure refers to a network of natural and semi-natural systems that provide environmental, social, and economic benefits. This skill encompasses the design and implementation of practices such as green roofs, permeable pavements, and urban forests to manage stormwater, improve air quality, and enhance biodiversity. Knowledge of Green Infrastructure is used to create sustainable urban environments by integrating natural processes into urban planning and development, thereby mitigating the impacts of climate change and urbanization.

HEC-HMS is a hydrological modeling software developed by the U.S. Army Corps of Engineers to simulate the precipitation, runoff, and streamflow of watersheds. It allows water resource managers, engineers and other professionals to forecast river flows, calculate dam and levee capacities and design reservoirs. HEC-HMS uses precipitation data, soil characteristics, land use and vegetation cover, and other parameters to simulate the hydrological cycle and hydraulic processes in a watershed. The software is used to support water management and planning decisions by providing data and information to stakeholders.

Natural Channel Design refers to the process of creating and restoring stream channels to mimic natural conditions, promoting ecological health and stability. This skill involves understanding hydrology, sediment transport, and habitat requirements to develop channels that support diverse aquatic and riparian ecosystems. Knowledge of Natural Channel Design is used to enhance water quality, reduce erosion, and improve flood management by integrating natural processes into channel design and restoration projects.

Professional Traffic Operations Engineer (PTOE) certification is a nationally recognized credential that validates the knowledge, skills, and abilities of transportation professionals in the field of traffic operations. It is designed for engineers and other professionals who work in the planning, design, and management of transportation systems to ensure the safe and efficient movement of people and goods. The certification process includes a rigorous examination that covers a wide range of topics, including traffic flow theory, geometric design, traffic signal operations, and safety. Holding a PTOE certification demonstrates a commitment to excellence and professionalism in the field of traffic engineering.

Water Quality Modeling refers to the process of simulating the physical, chemical, and biological processes that affect water quality in various environments. This skill encompasses the use of mathematical and computational techniques to predict the behavior of pollutants and assess the impact of different management strategies on water systems. Knowledge of Water Quality Modeling is utilized to inform decision-making in environmental management, regulatory compliance, and the development of water quality improvement plans.
