Abstract A new computer program, FLASH (Flow-Log Analysis of Single Holes), is presented for analysis of borehole vertical flow logs. The code is based on an analytical solution for steady-state multi-layer radial flow to a borehole. The code includes options for (1) discrete fractures and (2) multilayer aquifers. Given vertical flow profiles collected under both ambient and stressed (pumping or injection) conditions, the user can estimate fracture (or layer) transmissivities and far-field hydraulic heads. FLASH is coded in Microsoft Excel 5 with Visual Basic for Applications routines. The code supports manual and automated model calibration.
