Perennial springs provide information to predict low flows in mountain basins

Channel-reach morphology in mountain drainage basins

A classification of channel-reach morphology in mountain drainage basins synthesizes stream morphologies into seven distinct reach types: colluvial, bedrock, and five alluvial channel types (cascade, step pool, plane bed, pool rime, and dune ripple). Coupling reach-level channel processes with the spatial arrangement of reach morphologies, their links to hillslope processes, and external forcin...

The layered structure in exchange flows between two basins (Middle and Southern basins of the Caspian Sea)

Ocean waters often show layered structures especially where exchange flow between two basins occurs. These structures are often attributed to processes such as double.diffusive convection, internal waves, turbulent modulated mixing. In this paper by examining the vertical structures of temperature, salinity and density, of the middle parts of Caspian Sea it is shown that such layered structure ...

Data to Provide Relevant Information

We are always seeking for relevant and useful information. However, the information provided to us generally does not conform to our information needs, mainly manifested from two aspects: One, when we search for some items, the number of candidate items is so large that targeting the most relevant items is difficult. Two, when our goal is to obtain some high-level and global type of information...

A Mathematical Model for Analysis of Mountain Drainage Basins

Regional Analysis Low Flows in the Karkheh and Karoon Catchments

Analysis of low flow is one of the important considerations in any water resource project. Meanwhile, as a general idea it seems that flow control is more important than drought mitigation but it is necessary to pay more attention to drought problem in future projects. In this paper, available data for 28 selected watersheds were analyzed and then Flow Duration Curve was drew, and discharge of ...
