The RIVERMorph tab provides for importation of stream reach design files from the 2-dimensional RIVERMorph program into Natural Regrade to produce a 3-dimensional design. The resulting 3-dimensional design is in a .tin format that can be directly exported to machine-control programs like Carlson Grade that guide heavy equipment operators to build the design without the need for additional field survey and staking work.
The Select RIVERMorph File button accesses the Open RIVERMorph Project - (rmp) file selection dialong box. The user can browse through RIVERMorph files to select the file to import, or select the file from a list of recently used files. When the user highlights the desired file and clicks the Open button, the file name appears below the Select RIVERMorph File button and the user is ready to begin importing the desired RIVERMorph reach.
The Select Reach dialog box then pops up and the user highlights the desired reach and clicks OK. Natural Regrade will advise the user by a pop-up dialog if there is a mismatch in slopes or, if the slope range is valid, will display the Place RIVERMorph Reach pop-up dialog box.
The Place RIVERMorph Reach dialog box gives the user options for Natural Regrade to place the reach at appropriate locations based on design .tin elevations, or at user-specified points of known elevation. If the user selects a point with a slope mismatch, Natural Regrade will place the reach at the nearest matching point.
When the reach has been placed, it will be displayed in the reach list on the RIVERMorph tab in the Channel "(name)" Settings dialog box. The user can highlight any reach on the list and click on the View button to get a summary of the reach details. The Remove button allows the user to select a reach from the list and delete it from the current GeoFluv project. The Reposition button allows the user to revise athe RIVERMorph reach location in the GeoFluv project.
When the user clicks the OK button at the bottom of the RIVERMorph tab dialog box, the RIVERMorph reach design data are imported into the GeoFluv design input data in Natural Regrade. The user can use the Preview button on Output tab to verify the reach location. When the user clicks the Draw Design Surface button on the Output tab, the RIVERMorph data are made into a 3-dimensional design in the GeoFluv project.
