ABSTRACT: The Digital Elevation Model (DEM) data from traditional stereo photogrammetric methods is inadequate in providing accurate vertical parameters to feed hydrological models for low-lying, extremely flat areas. High-resolution Light Detection And Ranging (LiDAR) data provides the robust capability of capturing small variations in low-relief playa wetlands. This research focuses on the development of a procedure with applicable protocols to produce LiDAR-derived 3D wetland maps and extract the critical surface parameters (i.e., watershed boundaries, flow direction, flow accumulation, and drainages lines) for playa wetlands. The topo-hydrologic conditions of playa wetlands were evaluated at the watershed level. The results show that the majority of playa wetlands’ topographic conditions have been substantially changed and the SSURGO and the NWI data cannot fully reflect current topographic reality for playa wetlands. The methodology and statistical results contribute directly to the wetland conservation programs and are potentially applicable to the management of other wetlands across the region and globally.
