Basin scale hydrologic/water quality models that are capable of predicting long-term effects of land management are necessary to aid water quality assessment of river systems.
Instead, the geographic region for the entire input stream's map layer is used.

Basin Modeling
Compute sub-basin runoff in either a lumped or linearly distributed fashion.
Determine losses based on several methods, including Green & Ampt, SCS Curve Number, gridded SCS Curve Number, and the
Initial/Constant method.
basin A synclinal structure, roughly circular in its outcrop pattern, in which beds dip gently toward the center from all directions.

Biology
The flora and fauna of rivers are much different from those of the ocean because the water is sweet (non-salty). Living things in a river must be adapted to the current of the moving water.

A classification system that represents the relative position of streams in a drainage basin. The highest tributaries in the basin are first order streams.
The area is glaciated and has numerous small wetland basins. The uplands are used almost exclusively for agriculture. Landsat TM data from May and September of 1986 processed by methods developed by Koeln and Wesley (1987) and Koeln et al.
Dobson and Alf Shepherd projected the amount of water needed for energy produ ction and compared it with the amount of water available in each basin in the United States.
Similar to a large catch basin. Typically, a watershed boundary or perimeter is comprised of ridgetop or high elevation areas. All water runs downhill by the force of gravity, so you can think of a watershed as a drainage basin.
Moderate accuracies (1:5,000) are used in most pipelines, sewers, culverts, catch basins, and manhole stakeouts; general residential-building foundation and footing construction; major highway pavement; and concrete-runway stakeouts.
I concentrated on deep ocean basins where the artifacts were most noticeable and the bottom flat, making the edits easier to accomplish. By contrast, the fractured topography of mid ocean ridges received minimal editing.

Continental Divide:
The line of high ground that separates the oceanic drainage basins of a continent; the river systems of a continent on opposite sides of a continental divide flow toward different oceans.
From those you would select only areas where people live (basing your criterion on data about population density, for example). Then you would choose the precipitation records for those areas only and perform your analysis of this subset.
In addition, in climatological studies surface water storage is a critical element of the water cycle since the analyses integrate all hydrologic processes (precipitation, runoff, evapotranspiration, and so on) over a given basin; ...
