Has anybody designed an earthen basin that desalinates runoff? Should this basin be lined to prevent sub-surface salt migration? We are having plants die that are downstream from snow stockpile runoff.
Has anybody prepared cost comparisons between conservation developments and conventional developments, particularly with regard to commercial and industrial sites?
The city of Chicago requires that these restrictors be provided. There are some successful pre-fab ones on the market now. The skupper is the overflow provision and there are general enough drains to accommodate the 100% drainage in an overflow condition. Debris and ice are apparently not an...
Thanks guys. You confirmed my suspicions. To answer your question, I've only worked with HEC-RAS a little bit. I understand it but am not proficient with all its nuances. I'm more familiar with the Rational Method and mannings. Their results are only as good as their input and can be...
Apparently 3D is some add-on software that works with HEC-RAS. I'm just now trying to understand what it entails. I've worked with AutoCAD Civil and 3D earthworks calcs before but had not heard of 3D hydraulic modeling until this morning. I'm told 3D can evaluate velocities more precisely.
What are the advantages of 3D modeling? We have a project where it was suggested that 3D modeling may be necessary since we are proposing to grade around some existing trees that will remain in place. They are currently along the bank but will end up in the middle of the river. Can't we make...
