Metodología para el cálculo de la humedad del suelo usando parámetros topográficos(MDE), climáticos y edáficos en un sector del piedemonte depositacional del municipio de Villavicencio
(Universidad Nacional de Colombia - Sede Bogotá, 2012)
El estudio estableció una metodología para estimar la humedad del suelo a partir de atributos geomorfométricos e hidrológicos derivados de los modelos digitales de elevación, MDE, en un sector del piedemonte depositacional ...
Controls on stand transpiration and soil water utilization along a tree density gradient in a Neotropical savanna
(Elsevier Science, 2008-06)
Environmental controls of stand-level tree transpiration (E) and seasonal patterns of soil water utilization were studied in five central Brazilian savanna (Cerrado) sites differing in tree density. Tree density of Cerrado ...
Use of hydrogeomorphic indexes in SAGA-GIS for the characterization of flooded areas in Madre de Dios, Peru
(Universidad Continental, 2017)
The work aims to identify and cartographically represent sensitive areas (scenarios) to river flooding in the lower section of the Madre de Dios hydrographic unit in the Peruvian Amazon, from the use of digital terrain ...
Debris flow susceptibility mapping using frequency ratio and seed cells, in a portion of a mountain international route, Dry Central Andes of Argentina
(Elsevier Science, 2020-06)
Debris flow and floods represent one of the main natural hazards that impact transport infrastructure, causing serious damage, economic losses and hinder regional economic development. These processes are eventually ...

Modelagem do terreno e mapeamento digital de solos por extrapolação das relações solo-paisagem
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Ciência do Solo, 2016-05-31)
Research on digital soil mapping (DSM) in Brazil is subject to the existence of legacy soil data obtained through conventional methods for extrapolation of soil-landscape relations. In areas with no available soil maps, ...
Predicting spatial variability of selected soil properties using digital soil mapping in a rainfed vineyard of central Chile
(Elsevier, 2020)
Soil physical properties influence vineyard behavior, therefore the knowledge of their spatial variability is essential
for making vineyard management decisions. This study aimed to model and map selected soil properties ...
Digital elevation models (DEM) used to assess soil erosion risks: a case study in Boyaca, Colombia
(Universidad Nacional de Colombia, 2016-05-01)
The objective of this research was to develop a model for assessing the risk of erosion, exploring the potential of DEMs from SRTM, ASTER, ALOS PALSAR and one made with interpolation of a 1:25,000 contour map to calculate ...
