A procedure for delineating a search region in the UAV-based SAR activities
Geomatics, Natural Hazards & Risk, 2017 We propose a simple geometrical approach for delineating a region above which an Unmanned Aerial Vehicle (UAV) should fly to support the Search and Rescue (SAR) activities.

Comparison of Algorithms and Parameterisations for Infiltration into Organic-Covered Permafrost Soils [PDF]
, 2010 Infiltration into frozen and unfrozen soils is critical in hydrology, controlling active layer soil water dynamics and influencing runoff. Few Land Surface Models (LSMs) and Hydrological Models (HMs) have been developed, adapted or tested for frozen ...

Geomorphometry 2020 - Conference proceedings
, 2020 Geomorphometry is the science of quantitative land surface analysis. It gathers various mathematical, statistical and image processing techniques to quantify morphological, hydrological, ecological and other aspects of a land surface. Common synonyms for geomorphometry are geomorphological analysis, terrain morphometry or terrain analysis and land ...

High resolution geomorphological classification of benthic structure on the Western Pacific Seamount
Frontiers in Marine Science, 2022 The benthic structure of seamounts is critical for understanding the ecological environment and for assessing the influence of resource exploitation. However, the characteristics of the benthic structure of the seamount, especially for guyot, are still ...

A New European Slope Length and Steepness Factor (LS-Factor) for Modeling Soil Erosion by Water [PDF]
, 2015 The Universal Soil Loss Equation (USLE) model is the most frequently used model for soil erosion risk estimation. Among the six input layers, the combined slope length and slope angle (LS-factor) has the greatest influence on soil loss at the European ...

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 4, April 2025.Abstract Arctic shrub productivity trends display variability at multiple spatial scales. Fine‐scale studies have generally observed the greatest shrub expansion in landscape positions that accumulate water and nutrients. While considerable work has focused on the mediating effect of these resources on growth responses to warming, less is known about ...
