Sea-level rise and storms cause major changes on coastal landscapes, including shifts in elevation, ecosystem type (for example, dunes and tidal wetlands), soils, and plant communities. Because these changes can have impacts on human communities, the local economy, and ecosystems, understanding how, when, and why these changes occur can be important for informing policy and natural resource management decisions. However, much is still unknown in our understanding of and ability to forecast coastal landscape change, and many current modeling approaches do not include important feedbacks between the physical landscape and the species inhabiting it. Examples of these types of feedbacks include the rapid development...

The three-dimensional (3D) form of the Earth’s surface results from both abiotic and biotic forces. Major abiotic forces, such as tectonic uplift, erosion, and climate, exert strong influence over land surface morphology. Biotic forces, including, significantly, humans, also shape the landscape, but often at different temporal and spatial scales and magnitudes than geologic forces. Because the processes shaping the land surface, as expressed in its topography, are ongoing, topographic change is ever present and is a factor that must be broadly considered in studies of natural and built environments. Remote sensing data, especially in the form of derived high-resolution measurements of the topography, have been widely...
