We know HEC-RAS has two units (i.e., feet or meter), so people can choose which one to use. <br /><br />Here is a unique situation. We have a HEC-RAS model used in the Souris River System which covers both Canada and US; the model is calibrated by Army Cops of Engineers in unit of feet. Then we in Canada want to use this model, but our unit here is meter for flow, lake level, and discharges. <br /><br />So can we simply change the unit to meter in HEC-RAS, and have our inputs with this model? Or we need to have our inputs converted to feet, then to feed inputs into this model? I feel that latter makes more sense. What is your thought?<br /><br />West<br />Westhttps://www.blogger.com/profile/14027840397254644387noreply@blogger.comtag:blogger.com,1999:blog-1675184707067447729.post-25532978397613761412019-01-08T07:33:47.884-08:002019-01-08T07:33:47.884-08:00when i do that it appear error in saving file alra...when i do that it appear error in saving file alrady open how i solve this problemAnonymoushttps://www.blogger.com/profile/05280251840617156551noreply@blogger.comtag:blogger.com,1999:blog-1675184707067447729.post-41873729015683179132017-08-17T09:06:45.038-07:002017-08-17T09:06:45.038-07:00Hi JC, I got the same error, but it converted the ...Hi JC, I got the same error, but it converted the projection anyway!
