In traditional watershed delineation and topographic modeling, surface depressions are
generally treated as spurious features and simply removed from a digital elevation model …

The spatial relationship between wetlands and streams influences their structure and
function, and is currently tied to the regulatory status of wetlands. Efforts have been made to …

With extraordinary resolution and accuracy, Light Detection and Ranging (LiDAR)-derived
digital elevation models (DEMs) have been increasingly used for watershed analyses and …

Drainage network analysis is fundamental to understanding the characteristics of surface
hydrology. Based on elevation data, drainage network analysis is often used to extract key …

A new method is introduced to delineate hydrogeomorphic elements from light detection and
ranging (lidar) digital elevation models. Landscape segmentation is achieved using an edge …

In terrain analysis and hydrological modeling, surface depressions (or sinks) in a digital
elevation model (DEM) are commonly treated as artifacts and thus filled and removed to …

Wetlands are important ecosystems that provide many ecological benefits, and their quality
and presence are protected by federal regulations. These regulations require wetland …

This paper presents a new method for extracting flow directions, contributing (upslope)
areas, and nested catchments from digital elevation models in lake‐dominated areas …

In this article, a method for drainage network extraction from high‐resolution digital elevation
models (DEMs; eg, those derived from airborne laser swath mapping) is presented, which …

Conventional hydrologic analyses of digital elevation models (DEMs) perform well in areas
of high topographic relief, where surface water flow is typically unidirectional, convergent …
