A phased creation of digital elevation model for hydrodynamic modeling in flat zones

open access: yesFacta universitatis - series: Architecture and Civil Engineering, 2022
Hydrodynamic modeling of rivers with flood simulation requires an accurate description of the riverbed and inundation morphology. Depending on a geodetic survey method and data collected, the digital elevation models with different accuracy can be created.

VARIATION IN THE FLOWERING PHENOLOGY OF AN EPIPHYTIC BROMELIAD ALONG AN ELEVATIONAL GRADIENT

open access: yesActa Biológica Colombiana, 2020
Elevational patterns in flowering phenology have been reported for trees, shrubs and herbs. However, for vascular epiphytes that rely on atmospheric sources for humidity and nutrients, and depend on phorophyte microhabitat, elevational patterns of ...

Improved Estimates of Population Exposure in Low-Elevation Coastal Zones of China [PDF]

open access: yesInternational Journal of Environmental Research and Public Health, 2019
With sea level predicted to rise and the frequency and intensity of coastal flooding expected to increase due to climate change, high-resolution gridded population datasets have been extensively used to estimate the size of vulnerable populations in low-elevation coastal zones (LECZ). China is the most populous country, and populations in its LECZ grew
