Cosmogenic nuclides have been used successfully to quantify long-term rates of sediment generation in arid lands. However, cosmogenic nuclides have been applied outside of arid environments in only a few locations. We have collected 37 samples from the tropical, humid Rio Chagres watershed in Panama as a methodological test. Since the headwaters of the Rio Chagres watershed are remote, and rela...

A 6-year study of mussel communities and their • habitat in the Neversink River basin in southeastern New York found that the principal factors apparently affecting mussel-species richness were site (reach) elevation, drainage-area size, channel width, bottommaterial composition, water velocity, shear stress at bankfull discharge, and water quality (acidneutralizing capacity (ANC) and concentra...

Water quality impairments are widespread throughout the upper Mississippi River basin due in large part to agricultural production practices. Many agencies have worked with landowners to implement various agricultural best management practices (BMPs) to reduce nutrient and sediment losses to streams and rivers. However, it has been difficult to document the effectiveness of these practices at f...

In this paper, we present the applications of spatial technologies-Geographic Information Systems (GIS) and remote sensing-in the international monitoring of river basins particularly analyzing the ecological, hydrological, and socio-economic issues along the Senegal River. The literature on multinational water crisis has for decades focused on mediation aspects of trans-boundary watershed mana...

Let f∶ Ki→Kj be an involution between these subgraphs. The vertex set of the graph fusion is defined by : (Vi − Ai) ∪ Vj − Aj ∪ a f a | a ∈ Ai For one image, the cell files are inferred from the basin alignments obtained from the adjacency graph of cells given by a watershed algorithm. But how to merge consistently the cell files extracted in the different images of the mosaic? Multiscale filte...

We used remotely sensed weekly snow water equivalent (SWE) and snow cover extent (SCE) data to investigate streamflow response to seasonal snowcover change over the Yukon watershed. We quantified the seasonal cycles and variations of snowcover (both SWE and SCE) and river streamflow, and identified a clear correspondence of river discharge to seasonal snowcover change. We also examined and comp...

Mapping soil texture in a river basin is critically important for eco-hydrological studies and water resource management at the watershed scale. However, due to the scarcity of in situ observation of soil texture, it is very difficult to map the soil texture in high resolution using traditional methods. Here, we used an integrated method based on fuzzy logic theory and data fusion to map the so...

In this article, the existing international laws in field of transboundary waters, as well water treaties and approaches used to resolve disputes, have been reviewed analyzed by using documents information. 
 As convention’s provisions, every state common river basin has right fair reasonable exploitation flow watershed its territory, with obligation not cause damage other countries. This ...
