Global system of rivers: Its role in organizing continental land mass and defining land‐to‐ocean linkages [PDF]

open access: yes, 2000
The spatial organization of the Earth\u27s land mass is analyzed using a simulated topological network (STN‐30p) representing potential flow pathways across the entire nonglacierized surface of the globe at 30‐min (longitude × latitude) spatial ...

Assessment of Soil Erosion Over Six Decades in a Long‐Term Experiment Using Fallout 137Cs and RUSLE: A South American Case Study

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Soil erosion remains a major global concern affecting agricultural productivity and land sustainability. This study investigates the magnitude and variability of soil erosion in a long‐term experiment (LTE) established in 1963 in Colonia, Uruguay, aiming to compare the performance of the 137Cs tracer technique and the RUSLE model across ...

Investigation of the relationships between basin morphology, tectonic uplift, and denudation from the study of an active fold belt in the Siwalik Hills, central Nepal [PDF]

open access: yes, 1999
The present study investigates correlations between an extensive range of geomorphic properties that can be estimated from a digital elevation model and the uplift rate on geological timescales.

Coal Mining as a Driver of Land Use and Land Cover Change and Degradation: A Case in Moatize City, Mozambique

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Coal remains a major global energy source despite ongoing environmental controversies, particularly, regarding climate change and landscape transformation. This study investigates the spatiotemporal dynamics of land use and land cover (LULC) in the Moatize Coal Basin (MCB), Mozambique, between 1990 and 2024, with a specific focus on land ...

Drainage basin characteristics from ERTS data [PDF]

open access: yes
The author has identified the following significant results. ERTS-derived measurements of forests, riparian vegetation, open water, and combined agricultural and urban land use were added to an available matrix of map-derived basin characteristics.

Double-diffusive convection • Buoyancy-Driven convection • Convection in an inclined porous slot [PDF]

open access: yes, 2013
The quantitative analysis of drainage system is an important aspect of characterization of watersheds. Using watershed as a basic unit in morphometric analysis is the most logical choice because all hydrologic and geomorphic processes occur within the ...

Isotopic characteristics of the Garonne River and its tributaries [PDF]

open access: yes, 2009
The Garonne is the largest river in the south-west of France, and its drainage basin stretches between the Pyrenees and the Massif Central mountains. Until now, no water stable isotope study has been performed on the whole Garonne river basin which is ...

Topological analysis of the human lymph node reticular network predicts outcome in breast cancer

open access: yesThe Journal of Pathology, EarlyView.
Abstract Axillary LNs (ALNs) initiate immune responses in breast cancer (BC) but how and when ALNs become dysfunctional, facilitating metastasis, is unclear. The fibroblastic reticular cell (FRC) network within ALNs provides structural support and mediates immune homeostasis, but we have yet to elucidate whether this network changes during BC ...
