    (use for flood stage, fluvial processes, gage height, stream current, stream flow, stream stage, streamflow data, streamflow modeling) stream discharge Volume of water in a stream passing a given point at a given moment in time, expressed as a measure of volume per unit of time, i.e. cubic feet per second, million gallons per day, or gallons. Erosion control has the potential to sequester carbon as well as restoring degraded soils and improving water quality. Since the second edition of Soil Erosion and Conservation was published in , soil erosion has assumed even greater importance because of the higher priority now being given to the environmental issues associated with sediment.

    The standard sieving, pipette, and hydrometer methods for soil particle size analysis (PSA) have three main drawbacks: (i) the procedures are tedious, (ii) the procedures are time consuming, (iii). To search for phrases, use quotation marks: "climate change smith" To search for combinations of words, separate them by "AND" or "+": climate + change + Smith If you don't use either of the above, the search will run on ANY keyword.

    Sediments in aqueous systems are of increasing interest to academics, researchers, practitioners and stakeholders around the world. This book not only covers the characteristics of the sediments themselves, but also their physico-chemical impact on aquatic .

The D50 is the median point of the distribution that divides the distribution in two equal parts.

The particle size for which 25% of the distribution is finer is the 25th percentile, or the D The D25 and D75 are also called quartiles. Theoretically, any percentile value. Nitrate uptake by benthic algae appears to account for a small portion of the NO3- removal.

Laboratory experiments suggest that most of the nitrate disappearance from the river reaches is caused by bacterial denitrification and nitrate reduction in stream sediments.
