\"\"<\/a>A notable characteristic of Maine’s heavily forested, post-glacial landscape is the ubiquitous patchwork of paired pit and mound features, often on the scale of single meters wide and decimeters to (rarely) a meter in-depth and generally caused by factors related to tree fall and underlying surficial geology.\u00a0 These and other small-scale topographic variations in the landscape – referred to as microtopography – play an important hydrologic role, intercepting surface overland flow during precipitation events and storing it as “puddles” or routing it to the shallow subsurface.\u00a0 School of Earth and Climate Sciences Ph.D. student Bea Van Dam<\/a>\u00a0and her advisor\u00a0Sean Smith<\/a> have investigated the use of remotely-sensed high-resolution elevation data from LiDAR (Li<\/strong>ght D<\/strong>etection A<\/strong>nd R<\/strong>anging), which is increasingly available across coastal and interior Maine, to detect and quantify spatial patterns of microtopography across different settings and land uses.<\/p>\n
