Wetland science research has earned great attentions and wetland assessment is an important part of wetland science characterized by complex context and various assessment methods. What's more, there is not unified standard on the evaluation of wetland functions. This paper enumerates the commonly used evaluation methods for different functions of wetland both at home and abroad. The advantages, disadvantages, application range of each method and relevant outcomes were discussed, which can provide a reference for the wetland assessment in our country.

The use of Unmanned Arial Vehicle (UAV) photogrammetry is a valuable tool to enhance our understanding of wetlands. Accurate planning derived from this technological advancement allows for more effective management and conservation of wetland areas. This paper presents results of a study that aimed at investigating the use of UAV photogrammetry as a tool to enhance the assessment of wetland ecosystems. The UAV images were collected during a single flight within 2½ hours over a 100 ha area at the Kameelzynkraal farm, Gauteng Province, South Africa. An AKS Y-6 MKII multi-rotor UAV and a digital camera on a motion compensated gimbal mount were utilised for the survey. Twenty ground control points (GCPs) were surveyed using a Trimble GPS to achieve geometrical precision and georeferencing accuracy. Structure-from-Motion (SfM) computer vision techniques were used to derive ultra-high resolution point clouds, orthophotos and 3D models from the multi-view photos. The geometric accuracy of the data based on the 20 GCP’s were 0.018 m for the overall, 0.0025 m for the vertical root mean squared error (RMSE) and an over all root mean square reprojection error of 0.18 pixel. The UAV products were then edited and subsequently analysed, interpreted and key attributes extracted using a selection of tools/ software applications to enhance the wetland assessment. The results exceeded our expectations and provided a valuable and accurate enhancement to the wetland delineation, classification and health assessment which even with detailed field studies would have been difficult to achieve.

This chapter discusses characteristics of wetlands, where they are found, history of loss and degradation, and regulation and conservation of wetlands. Although wetlands have received much less public attention and research than streams in Kentucky, they are equally important habitats because they perform ecosystem functions that are valuable to humans and wildlife alike. Functions include flood attenuation, filtration of pollutants and sediments, water storage and supply, and wildlife habitat, many of which have human values. The chapter closes with wetland protection successes and efforts to address shortcomings through development of wetland assessment techniques and improved wetland preservation and mitigation.
