9 Diver data view9.1 About the Diver and Data management ToolThis chapter describes the Diver and Data management tool of Menyanthes. Although started asa separate tool, it currently is fully integrated in Menyanthes. The main functions of this tool are:• Efficient importing of large amounts of data (from data loggers).• Simply and correctly joining of data from various reading rounds.• Detect, monitor, correct, and validate possible deviations of data loggers using manualmeasurements.• Record and comment on measurements and corrections to keep everything transparentand reproducible (the original data and all corrections are recorded).• Manage the technical data of piezometers and data loggers, including the changes ofthis data and their relation to the piezometric heads.• Sharing data in a multi-user environment with options for different user rights.• Effective and complete visualization of the data, reading rounds, comments andcorrections.Files from the data loggers of Van Essen (MON files) and Keller (IDC files) and manualmeasurements can be imported.Section 9.2 gives a quick walk through and section 9.3 provides more in depth information onthe various screens and functions of the Diver and Data management tool.the manual of the program Menyanthes. In this manual, the various functions of Menyanthes arediscussed. Menyanthes is a program for time series data management, visualization, statisticalanalysis, and time series analysis with the PIRFICT model.Only topics directly related to the use of Menyanthes are described. For a detailed descriptionof the theory on time series analysis in general, we refer to [Box and Jenkins, 1970; Hipel andMcLeod, 1994; Ziemer et al., 1998; Ljung, 1999]. A detailed description of the PIRFICT time seriesmodel and methods specific for Menyanthes is preserved in [Von Asmuth et al., 2002, VonAsmuth and Bierkens, 2005, Von Asmuth et al., 2006, Von Asmuth et al., 2008].The program is available in two versions: a Windows executable version and a p-file versionfor use with MATLAB. Both versions have the same functionality.9.2 Walk through of Diver and Data management tool (step by step)Release history of Menyanthes9.2.1 IntroductionThe button ‘Diver Data View’ in the tool bar starts the Diver and Data management tool.The button ‘Quadrant View’ brings the user back to the main Menyanthes window.First barometric data have to be imported (see section 9.2.2), before a database can be filledwith groundwater data (see section 9.2.3).9.2.2 Barometric compensatonCarry out the following steps when the values in your diver files are absolute (i.e. not yetcompensated for barometric pressure):Menyanthes Manual© KWR - 37 -
