Surface Water Records Software-WISKI

Are you able to process all the water data you collect? Is the data processing burden preventing you from collecting all the data you need? All too often the records you worked so hard to collect sit indefinitely in a form in which they cannot be used - punched tapes, charts, or data loggers.

WISKI is a comprehensive hydrologic information processing system that allows you to display and edit your data using advanced graphics and tools. It also allows graphical comparisons of your data across water-year boundaries. WISKI uses popular relational databases such as Oracle, SQL Server, Sybase and works on all types of client server systems such as Windows 95/98, NT, 2000, or UNIX.

WISKI includes a complete USGS compatible surface water computation program and powerful statistical tools for hydrologic studies. Program features allow hydrologic data management and reporting for :

Surface water data is read from gage heights from graphical recorder charts, data loggers and ASCII files. Includes editors for entering and editing datum corrections, time shifts, stage shifts, ratings, and formulas. Computes daily means discharges using multiple ratings with log and rectilinear interpolation. Rating shifts and datum corrections to compute instantaneous daily, monthly, and yearly mean discharge. All computations are USGS compatible. Includes plotting programs. Prints out all the standard reports from Primary Computation Sheets, to Year-End Discharge and many more.

Water balance program features unlimited uses the daily flows of streamflow stations and combines them using any mathematical equation. Allows computation of water balances between any number of stations.

MMM (max, min, mean), a generic report program, summarizes any data type into a usable report - conductivity, barometric pressure, dissolved oxygen, temperature.

Sediment Computation and Report Program uses instantaneous discharge (cfs) and sediment concentrations (tons/day or tons/hour) to compute and print out the standard USGS report.

Stage reads in gage heights and generates water level reports at stage-only stations such as lakes and reservoirs.

Graphical Programs graph flow and stage hydrographs, storm mass curves and histograms, rating tables, discharge measurements.

Precipitation Program reduces rainfall data recorded graphically on punched tape, data loggers, or in ASCII files to hourly, monthly, and yearly totals. Computes and stores the maximum short duration intensity series for unlimited storms per water year.

Ground water

Snow survey records including snow depth and density.

The basic WISKI software package includes a time-series manager, BIBER the discharge measurement manager and a SKED the rating curve editor. Additional modules add digitizing capabilities, remote telemetry, automated data import from other sources, and automated reporting to Internet or Intranet web-pages.

Discharge Measurement Software - BIBER-SKED

For hydrographers that only need only the capability to manage discharge measurements and rating curves, and do not need to manage time-series data. Two modules have been combined to create the BIBER-SKED package.

The BIBER module is a discharge measurement and evaluation program. This is a particularly powerful program to use with agencies that don't use standard rated current meters but individually rate each meter and/or propeller. The BIBER module manages data from multiple meter/propeller combinations and provides comprehensive data reporting. AquaCalc data can be directly imported into this software and BIBER data is designed for direct implementation with the WISKI system. All results are stored directly in the database and are available for the creation of rating curves using the SKED module.

Due to the fact that the BIBER is able to work on local databases, it can be installed on stand alone laptops, so the BIBER can be used in the field at the gage for interactive discharge measurements. The results of measurement can be shown immediately on the screen and can be compared to other measurements and to the actual rating curve. Released measurements can be replicated into the WISKI database.

The BIBER measurement assistant advises the user through the input of verticals, bankpoint simple depths measurements and revolutions.

The SKED module is rating curve editor that uses the full capabilities of a graphical user interface to assist the hydrologist in developing, maintaining and shifting rating curves.

The SKED Rating Curve Editor allows statistical support for analysis of discharge measurements including multiple regression methods for fitting curves with up to five line segments for a single rating curve. Discharge measurements used in creating a rating can be filtered by stage, discharge, time, season or single point selectable. Instantaneous access to rectangular or log plots and power law function with or without vertical shift. A formula editor for user defined functions and predefined weir functions. The rating curve can be divided into as many as five segments and a regression analysis can be performed on each segment. Where an individual segment has few measurements, the software allows the insertion of artificial measurements called "support points" that aid in the analysis. Support points are typically needed in the high and low flow areas of a rating curve. SKED can also be used to create reservoir storage capacity curves and much more.
