An innovative index for evaluating water quality in streams.
A water quality index expressed as a single number is developed to describe overall water quality conditions using multiple water quality variables. The index consists of water quality variables: dissolved oxygen, specific conductivity, turbidity, total phosphorus, and fecal coliform. The objectives of this study were to describe the preexisting indices and to define a new water quality index t...

متن کاملErosion Hazard Index Methodology (EHIM) for Streams Erodibility Assessment (Ardabil-Province)
An erosion hazard index methodology (EHIM) was developed for assessing stream erosion. The index of stream erosion is designed as a management tool. Assessing stream erosion involves consideration of a range of aspects of streams and a value judgment about a desirable state. The assessment of the erosion indicators of streams was based on a state-wide assessment of physical stream condition. A ...
متن کاملData Quality for Temporal Streams
Temporal data pose unique data quality challenges due to the presence of autocorrelations, trends, seasonality, and gaps in the data. Data streams are a special case of temporal data where velocity, volume and variety present additional layers of complexity in measuring the veracity of the data. In this paper, we discuss a general, widely applicable framework for data quality measurement of str...
متن کاملAn Index Model for MPEG-2 Streams
. The MPEG standards are playing a more and more important role in many multimedia applications now, and will continue in the future. An effective index model for MPEG-1, 2 streams is presented in this paper. Moreover, the algorithm of constructing the index for MPEG-1, 2 streams is designed, as well as the solution to access any frame in the streams rapidly based on the model. The experimental...
