The present work deals with the problems related to the generation of Digital Terrain Model (DTM) of braided rivers by means of the open source GIS GRASS. In particular, we investigated how to optimize the terrain survey, that is how to reduce the density of topographic points that we have to survey and which is their best distribution, related to the employed interpolation method and with resp...

Analysis of 41 ERS 1 synthetic aperture radar images and simultaneous ground measurements of discharge for three large braided rivers indicates that the area of active flow on braided river floodplains is primarily a function of discharge. A power law correlation is found between satellite-derived effective width We and discharge Q, where We is the water surface area within a braided reach divi...

The zooplankton community of the lower Xingu River shows strong fluctuations in species richness and number of organisms during periods of water level fluctuation. Pulses of density and species richness are adapted to the pulses in water flows and water level. This is conected with reproductive strategies of some zooplankton groups. The spatial heterogeneity of the lower Xingu River consisting ...

—The longest river in North America, the Missouri, trends southeast from Montana across the mid continent of the United States, 3,768 km to its confluence with the Mississippi River near St. Louis, Missouri. Frequent flooding, a shifting, braided channel, and high turbidity characterized the precontrol “Big Muddy.” Major alterations occurred over the past century primarily for flood protection,...

Original scientific paper Studies on the evolution of paleo-channels in coastal areas are important for submarine engineering construction and to reveal changes in the global paleoenvironment. Thus, to explore the characteristics of paleo-channels during the late Last Glaciation in the western South Yellow Sea, digital terrain analysis method and ArcGis river extraction function were employed, ...

mTORC1 inhibitors were first approved for the use in metastatic kidney cancer. However, observed treatment benefit was highly heterogeneous among patients. Through case-based cancer genomic sequencing of therapeutic outliers, we can begin to appreciate the convergent evolution of given cancer pathways/phenotypes beyond genes in kidney cancer, like a braided river.
