Instruction overview

Version 3 and beta version 4 both have single national user interfaces through which information can be obtained for data-collection stations anywhere in the United States. Data recovery knoxville Information for stations within a state where StreamStats has been implemented can be obtained using the version 3 application for that state. 7 data recovery keygen Individual state applications may be accessed through the Version 3 State Applications link.


H2 database client The Beta Version 4 Application may be used to obtain information for streamgages in states that are not implemented in version 3. Dayz database Links to these applications appear in the gray box to the left on this page, and on most other StreamStats web pages.

Station information can be obtained using version 3 by (1) zooming in to the area in which a station of interest is located, (2) clicking on the Streamgage Information button , and then (3) clicking on the triangular map symbol that indicates the station location. I phone data recovery Station information can be obtained using beta version 4 by (1) either typing the streamgage number or name into location search box near the top of the sidebar or zooming in to the area in which the station of interest is located, (2) clicking on the Exploration Tools button , and then (3) clicking on the Query Streamgages button .

The output appears in a pop-up Web browser window. Database 3d At the top of the window is the USGS logo, followed by the title, “StreamStats Data-Collection Station Report.” Immediately below the title, the official USGS station number, the station name, and a hyperlink to the NWIS-Web site for the station are provided. Yorku database NWIS-Web is a USGS national database from which users can obtain period-of-record streamflow data time series and real-time information, if available, for the stations. O o data recovery For stations in North Carolina only, links appear below the NWIS link to two text files of additional streamflow statistics. Data recovery illustrator Below this, four tables are provided. Database management software The information that is available in the tables varies substantially among stations according to the data that have been collected there, and the analyses that have been done by the local USGS office on those data. Database normalization example Descriptive Information Tables:

Station type: Indicates the type of record collected at the station. Database virtualization Possible types are: continuous-record streamgage, low-flow partial-record station, peak-flow partial-record station, peak- and low-flow partial-record station, miscellaneous-measurement station, peak-flow partial record and stage-only, continuous-record stage-only, and undefined.

Regulated?: Indicates if streamflow at the station is affected by flow regulations or diversions. Data recovery machine Possible values are True, False, or Unknown

Hydrologic unit code: The 8-digit hydrologic cataloging-unit number assigned to the drainage basin in which the station is located. Data recovery cell phone Additional information can be obtained at http://water.usgs.gov/nawqa/sparrow/wrr97/geograp/geograp.html

These tables may contain any of potentially hundreds of physical characteristics of the drainage basin that contributes streamflow to a data-collection station. Data recovery wizard free The table is separated into sections of characteristics of the same type. Pokemon x database The types may include precipitation, temperature, climate, runoff, flood depth, recharge, topographical, soil, geological, stream channel, basin dimensional, and burned area characteristics, as well as additional descriptive information. Data recovery chicago The table consists of four columns:

• Citation Number – gives a number that corresponds with the Citation Number in the Citations table. R studio data recovery full version Each physical characteristic and streamflow statistic that is provided by StreamStats has been published previously in a report that is cited in the Citations table and is referenced by the Citation Number in the other tables.

These tables may contain any of more than 1,400 streamflow statistics separated into as many as 26 sections of statistics of the same type, such as peak-flow statistics, low-flow statistics, and flow-duration statistics. Database wiki The tables include up to 13 columns:

• Standard Error, percent – the standard error, in percent, of the computed statistic, which indicates there is an approximately 2/3 chance that the true value is within the given percentage of the provided value

• Variance, log-10 – the variance of the estimate, as computed from the base-10 logarithms of the data that were used to compute the statistic

• Lower 95% Confidence Interval – the lower end of the interval within which there is a 95 percent chance that the true value of the statistic occurs

• Upper 95% Confidence Interval – the upper end of the interval within which there is a 95 percent chance that the true value of the statistic occurs

Typically, when a new value of a statistic is published for a station, and the new value was computed using a longer record or improved methods, or both, then the new value is considered to supersede the older value. Data recovery freeware As a result, normally when new values of a statistic become available they replace the older values in the database that stores the statistics for StreamStats. Database clustering However, StreamStats can provide multiple values of the same statistic in cases where there is justification to do so. Icare data recovery An example is where a state has regulations that require the use of statistics from a specific report, but newer values have become available since the report was published. Data recovery jacksonville fl In such cases, IsPreferred? will be set to Y for the newer value and to N for the older value, and both values will appear in the statistics table.

Unless otherwise noted, all streamflow statistics presented in the output tables, except low-flow frequency statistics, were computed on the basis of water years, which begin October 1 of the preceding year and end September 30 of the given year. 510 k database search Low-flow frequency statistics, such as the 7-day, 10-year low flow, were computed on the basis of climatic years, which begin on April 1 of the given year and end on March 31 of the following year. Database engineer Statistics that were computed using data from nonstandard time periods or periods of less than a year will indicate those time periods in their names and definitions.

These tables contain columns of the citation numbers given in the previous tables, the corresponding citations for the reports that contain the statistics, and links to the online versions of the reports, respectively. Data recovery california Users can refer to those reports to determine when, why, and how the statistics were calculated.

Many of the statistics presented in the tables have an associated citation of “Imported from Basin Characteristics file.” The Basin Characteristics File (BCF) was a USGS database that was retired in the late 1990s. Moto x data recovery No time tags were associated with any of the data entered in the BCF. Database administrator As a result, users should understand that information from the BCF is likely to be 20 or more years old. Database acid In many cases, newer information is available in reports published by the various USGS Water Science Centers. Database 10g Users should check the Web pages of the individual Centers to determine if reports containing newer statistics are available.
