WISKI
Water Resources Management
Archiving and management of measured data
Measured data from different sources can be archived and managed directly:
Automatically and manually recording measuring devices
Remote calls
Manual data collection carried out during observation and checking trips
External data
Data archives
Digitalisation
WISKI provides cross media availability for all relevant parameters, e.g.:
Relative and absolute water level
Discharge
Velocities
Water and air temperature
Precipitation
Qualitative quality parameters, such as conductivity, pH value, cloudiness and other chemical-physical parameters
Measuring point height and ground level elevation (including history management) etc.
Self defined parameters can be added by the user.
All standard hydrological basic data is managed in concise basic data sheets (tabs). All measured data is stored systematically, continuously and centrally in a single database.
Discharge measurements are generated and evaluated (BIBER), and rating curves are adapted, validated and updated (SKED). WISKI offers an extraordinarily high level of data security, as original raw data is always maintained within the system. The processing and evaluation of measured data is always carried out on copies of the raw data. The GUI (graphical user interface) facilitates day-to-day operations with your data. Measurement network structures of any complexity are arranged in clear hierarchical structures - including your specific data set.
Collection of measured values
WISKI offers optimised tools for all means of data collection:
Automatic remote data calls via telephone, GSM, FTP, Internet (SODA)
Digitalisation of analogue recordings (gauge charts, precipitation sheets) (DIGIT)
Reading of field devices and data loggers
Optimised and adapted portable recording masks
Web interfaces
Extensive automated import routines and formats
Copy & Paste from other applications
Option for direct graphic visualisation / online monitoring of incoming data
All collected original data is archived as read-only data in the central database. All users can access data at any time.
Validation of measured data
Sophisticated graph and table tools (e.g. the outstanding graphical data editor) are available for validation checks of your data, i.e. observation, processing, and correction. Your measured data can be passed through automatic or manual tests and plausibility checks as it is read into the system.
The following are among the available test criteria:
limit value, distance, gradient (time or value difference)
completeness, periods (over/undershot of admissible drawdown values at certain times/periods)
calibration (daily, monthly, annual) and
own check algorithms (formula editor).
Furthermore, a commenting system and Quality Flag System with information on data quality, processing status, time and the way the work was carried out are also a part of the functions offered by WISKI. Status monitoring mechanisms with an alarm function are also available.
Assessment and analysis of measured data
WISKI offers a multidisciplinary system with comprehensive hydrological and meteorological evaluation tools, which can be used to analyse your measured data (e.g. double mass analysis or data validation in the gauge triangle). Powerful calculation, analysis, visualisation, reporting and import/export functions are available for the assessment and analysis of data.
Internationally standardised statistical and evaluation procedures and calculation rules (e.g. extreme value statistics, duration curves, trend analyses, long-term values) are integrated. WISKI is capable of carrying out comprehensive linear and multiple regression analyses across several segments and types. You can also integrate your own calculation algorithms by associating formulae with your data (e.g. calculation of representative flow velocity from locally measured velocities of an H-ADCP). An internal programming interface is available for project specific extensions.
Presentation of measured data
Several tools are available for the presentation of your measured data.
Complex evaluations (e.g. graphs and reports) can be generated directly through the graphical interface.
Automatic and manual generation of graphs and reports for arbitrarily selectable time periods (e.g. monthly and annual reports)
Forwarding, processing and integration of data or assessments in external formats (e.g. MS Excel, PDF, RTF, BMP, JPG, PNG) or in any type of document (e.g. Word files) is available
Evaluation according to different national rules and standards, e.g. German Guideline for Water Gauging and Discharge Measurements (Pegelvorschrift) or German Hydrological Yearbook Guideline, ISO-standards or USGS guidelines
Direct interface for Web display (Internet and Intranet)
Spatial evaluation through a direct connection to your Geographic Information System (GIS), for example for the generation of spatial interpolated precipitation or the current status of your measurement network
Technical integration and maintenance
Modular client-server application
Highly reliable backend through deployment of professional data base systems (ORACLE, MSSQL)
Project teams from hydrologists and IT-specialists
Advantages of Operative Processes
WISKI automatically meets legal requirements for the collection and publication of data, which is required in order to evaluate current predictions for water budgets, with consideration of the increasing number of measured points to be monitored (locations, positions), and of the increasing demand for information and the need for higher precision and better quality control. The increasing demand for data from environmental compatibility studies, flood protection, dry and drought analyses, as well as studies on climate change, river area and dam management can be easily met.
WISKI is a central, optimised solution for management and especially analysis and archiving of all relevant data with regard to an extensive hydrological network. The system meets process requirements for hydrometric activities, and guarantees collective data maintenance of quantitative hydrological and water quality data in one archive. Work processes and company processes are automated and optimised.
Support and maintenance expenditure is reduced. Central data storage provides cross-organisational access.
Automated plausibility checks mean less effort in data validation.
Furthermore, WISKI offers support via its unique Quality Flag system:
Centralised, automated data exchange with external organisations
Automated remote call system
Simple integration of flood water warning and alarm system
Easy integration of external hydrological models via KistersDataProvider.
