Importing Data to Vflo™
To develop a Vflo™ model, data from many different sources and formats may be imported to the program (see Data requirements). This page serves as a quick file formatting reference for the many data types that may be imported to Vflo™.
Contents
Parameter maps
Parameter maps may be loaded by three different means:
- 1. Using AutoBOP.
- 2. With the File | New | Use ASCII File option (see Developing a Vflo™ model with GIS maps.
- 3. Using the Tools menu.
For descriptions of the Vflo™ parameters listed below, see the Hydraulic properties and Infiltration parameters pages. Once parameter data is loaded, the Vflo™ model is saved as a single BOP (basin overland properties) file (*.bop).
- Flow direction maps
- Note: As an alternative to GIS development, flow direction may also be automatically calculated using AutoBOP.
- Roughness maps
- Slope maps
- Channel width maps
- Channel side slope maps
- Baseflow maps
- Hydraulic conductivity maps
- Wetting front maps
- Effective porosity maps
- Soil depth maps
- Initial saturation maps
- Abstraction maps
- Impervious maps
Evapotranspiration
See Evapotranspiration file format requirements for instructions.
Shapefiles
See Shapefiles.
Background maps and images
See Background maps and images. Background images must be in the same projection as the parameter maps used to develop the Vflo™ model.
Rating curve, cross section, and reservoir files
Rated channel cells require area-stage and discharge-stage rating curves to define channel hydraulics. Cross section cells use distance-elevation data pairs. Reservoir cells require storage-stage and stage-discharge curves. See Preparing rating curve and cross section files for instructions on formatting data files for each of these cells.
Rainfall files
Key information regarding supported rainfall data formats may be found at Overview: Precipitation. Once loaded, rainfall data may be saved in a single RRP (rainfall rate properties) file (*.rrp).
Single rain gauge
See Formatting single rain gauge and design storm files.
Design storm
See Formatting single rain gauge and design storm files.
Interpolated gauge
The interpolated gauge option requires data for multiple rain gauges to be loaded in a single file. See Formatting interpolated gauge files for instructions.
ASCII rainfall
See Formatting ASCII rainfall files.
CSV rainfall
See Formatting CSV rainfall files.
UF (Universal Format) radar
See UF and Level II file formats.
Level II radar
See UF and Level II file formats.
Filter files
Filter files, or BAG (basin average group) files (*.bag), are used to harmonize data established in different projections. See Creating filter files for information and instructions.
Observed data
Observed flow data is used for model calibration. For information about formatting observed data for a single cell, see Observed data file format for a single cell. For information about formatting observed data for several cells in a single file, see Observed data file format for basin.
