Geomorphology is the scientific study of landforms and the processes that shape them. It involves analyzing the physical features of the earth's surface, such as mountains, valleys, rivers, and coastlines, to better understand how they were formed and how they are changing over time. Geomorphology combines elements of geology, geography, and other related fields, and requires specialized knowledge and techniques to accurately interpret and analyze data.

Hydrologic modeling is the process of simulating or estimating the behavior of the water cycle components (such as evapotranspiration, infiltration, runoff) and their impact on surface and groundwater resources over a specified area and time. It involves the use of mathematical equations and computer models to simulate the various components of the hydrological system. This specialized skill requires knowledge of hydrology, engineering, and numerical methods as well as proficiency in hydrologic modeling software. The results of hydrologic modeling can be used for a wide range of applications, such as flood forecasting, water resource management, water quality assessment, and climate change impact assessment.

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.

Total Maximum Daily Load refers to a regulatory framework used to determine the maximum amount of a pollutant that a water body can receive while still meeting water quality standards. This skill involves assessing pollutant sources, analyzing water quality data, and establishing limits to ensure the protection of aquatic ecosystems and public health. Knowledge of Total Maximum Daily Load is applied in the development of pollution control strategies and in the management of water resources to achieve compliance with environmental regulations.

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.
