Thanks for your input, civilman72. I'm very interested in your experiences in steep mountain areas. This is particularly valuable:
I design roads in steep mountain areas and have found that trying to maintain subcritical flow in a roadside ditch is usually impractical, both from a cost and...
Lincoln you make a good point - the client will have the system for around 20 years, and having to constantly fix erosion problems is certainly not a good outcome. I would feel more comfortable reducing the flow velocity.
Since we're going to line the channels with shotcrete, I was thinking of...
Thanks everyone for the replies. Much appreciated.
Sounds like my efforts would be better spent on erosion protection, rather than forcing subcritical flow.
The waste rock material on site is not overly competent, so I am thinking that shotcrete might be an option as it is plentiful on site...
I am working on a drainage problem that presents a number of interesting challenges. In a nutshell, it involves designing a system of drains to capture and convey runoff in a large open-cast mine. Due to the nature of this type of operation, the slopes along the ramps/haul roads are such that...
Can anyone suggest a tool for converting DEMs to flt files? The flt file extension refers to a "floating point grid" file. RAS Mapper uses files of this type for terrain when mapping HEC RAS outputs.
I understand that this file type is associated with ESRI Arc GIS - is there any way for...
