1. Assessing Water Erosion Processes in Degraded Area Using Unmanned Aerial Vehicle Imagery
ABSTRACT The use of Unmanned Aerial Vehicles (UAVs) and Structure from Motion (SfM) techniques can contribute to increase the accessibility, accuracy, and resolution of Digital Elevation Models (DEMs) used for soil erosion monitoring. This study aimed to evaluate the use of four DEMs obtained over a year to monitor erosion processes in an erosion-degraded ar

2. Indirect quantitative-qualitative pedologic geomorphic characterization in sub-basin of 7th order of the middle São Francisco watershed - northern Minas Gerais state
Abstract The characterization presented in this study aims to identify and map the different types of pedogeomorphic units found in a 7th order, the Pandeiros river basin, in the upper São Francisco River (1st order basin), located in the North of Minas Gerais State. A general panoramic view of the geodiversity is presented, since the Pedogeomorphic Maps al

3. Soils Developed on Geomorphic Surfaces in the Mountain Region of the State of Rio de Janeiro
ABSTRACT: The evaluation of soils in representative landscapes constitutes an opportunity to evaluate spatial distribution, discuss formation processes, and apply this knowledge to land use and management. In this sense, from the perspective of an environmentally diversified region, the aim of the present study is to evaluate the occurrence and understand th

4. Morfologia e sedimentologia da Plataforma Continental Interna entre as Prais Porto de Galinhas e Campos-Litoral Sul de Pernambuco, Brasil
The analysis of geomorphic and sedimentological characteristics of the inner continental shelf is an important propriety to studies of the coastal zone since they inform the conditions of the sea bottom, the predominant features and the types of associated sediments. Associated to morfodinamic study it can, for example, identify predisposed areas to erosive

5. Morphological and structural constraints on the dynamics of the river basin of the River Benevente - Espírito Santo / Condicionantes morfológicos e estruturais na dinâmica fluvial da bacia hidrográfica do Rio Benevente - Espírito Santo
The study of watersheds in the humid tropical environment, has acquired great importance in recent decades due to growing demand for water resources planning. However, many studies have confused the concept of watersheds, believing that this was simply a network of interconnected channels that form the hydrography of the land, thus making it as simple cartog

6. Sistema pedológico Planosolo-Plintossolo no Pantanal de Barão de Melgaço-MT / Pedological system Solonetz-Plinthosol in the Pantanal of Barão de Melgaço-MT
The Pantanal is the largest continental flood plains, comprising a mosaic of different habitats, maintaining plant diversity, animal and soil. It consists of eleven sub-regions, one of which the of the Pantanal of Barão de Melgaço, which is located north of the Quaternary sedimentary basin. It presents a spatial heterogeneity that is related to the diversi

7. A planície aluvial do médio rio araguaia: processos geomorfológicos e suas implicações ambientais / The alluvial plain of the middle Araguaia River: geomorphological processes and their environmental implications
The Araguaia River is the most important fluvial system of South America. With an area of 380.000Km, its includes two phytogeography regions that have a good part of planet biodiversity: Cerrado, in the south, and Amazonia Forest, in the north of Brazil. The high level of Cerrado ecosystem destruction and changes in the land using, after 1965, promoted an in

8. Attributes of an alluvial river and their relation to water policy and management
Rivers around the world are being regulated by dams to accommodate the needs of a rapidly growing global population. These regulatory efforts usually oppose the natural tendency of rivers to flood, move sediment, and migrate. Although an economic benefit, river regulation has come at unforeseen and unevaluated cumulative ecological costs. Historic and c
