Global extent of rivers and streams

Science, 2018
Expanding the role of rivers The surfaces of rivers and streams are interfaces for a host of chemical exchanges with the atmosphere and biosphere. For instance, carbon dioxide outgassing from rivers is estimated to be equivalent to one-fifth of combined ...

River classification and river network structuration in river auto-selection

2014 22nd International Conference on Geoinformatics, 2014
River auto-selection is an essential part of the automatic generalization of thematic maps. To complete the task of river selection, the key is to reasonably evaluate the importance of various rivers on the global structure. A grading system is needed here to quantify the importance.

Urban rivers are hotspots of riverine greenhouse gas (N2O, CH4, CO2) emissions in the mixed-landscape chaohu lake basin.

Water Research, 2020
Growing evidence shows that riverine networks surrounding urban landscapes may be hotspots of riverine greenhouse gas (GHG) emissions. This study strengthens the evidence by investigating the spatial variability of diffusive GHG (N2O, CH4, CO2) emissions

Ice Atlas 1985 - 1986. Monongahela River, Allegheny River, Ohio River, Illinois River and Kankakee River.

1987
Abstract : The ice maps in this atlas were prepared to document the 1985-86 ice conditions on those reaches of the Monongahela, Allegheny, Ohio, Illinois and Kankakee Rivers that are included in study areas for the River Ice Management (RIM) Program, namely river mile 0 to 12 on the Monongahela River, mile 0 to 17 on the Allegheny, mile 0 to 437 on the

Lunar Rivers

Science, 1968
Mature meanders in lunar sinuous rills strongly suggests that the rills are features of surface erosion by water. Such erosion could occur under a pressurizing ice cover in the absence of a lunar atmosphere. Water, outgassed from the lunar interior and trapped beneath a layer of permafrost, could be released by a meteoritic impact and overflow the ...

River Regime with Special Reference to River Nile

Journal of the Hydraulics Division, 1975
Regime theory of canals and rivers is reviewed and the concept of independent adjustment of slope, depth, and bed width was found irrelevent when applied to the River Nile channel, i.e., silt equation and flow equation. The silt equation relates the discharge, depth, and slope, and the median grain size of the bed.
