Description
Rather than write a numerical hydrograph separation tool, CFA has incorporated the numerical base-flow separation program “BFLOW,” developed by the by Arnold et al. (1995; Arnold and Allen 1999). BFLOW is an automated digital filter base-flow separation tool which performs a multi-pass separation of base-flow from total stream flow. In order to implement the windows executable BFLOW in CSIP, which uses a Linux platform, the windows emulator WINE (WineHQ 2012) was used within CSIP (Lloyd et al. 2012). For the ease of use, like the rest of the tools in CFA, BFLOW operates on uploaded or auto-extracted data. CFA also automatically generates and formats the data into the necessary input files for the BFLOW executable. Beyond simply performing the analysis and returning the results CFA’s base-flow analysis also graphs the outputs of BFLOW’s separation overlaid onto total stream-flow for a visual understanding of groundwater contributions to stream flow, see result .jpg. The result file (.out) of the BFLOW program is available for download like the other flow analysis modes in CFA.
