I have a site, on which I've created both a berm and a retention pond to contain runoff. I now need to see if this is retaing enough water at a certain surface elevation.
The existing site is one surface and the berm/pond are another surface.
Is there a way to do this?
I am trying to add an entry point to a retention pond that was created by grading tools. I will to entry point to be shaped like a trapezoid. I also want to grade a entry point to the slope of pond to control water erosion.
I have been trying to add the entry point for days.
I’m using 2011, due to printing issues in 2013. My question relates to determining how runoff gets diverted, or spreads out, after leaving a well defined channel.
I have a street intersection scenario. It’s a “Y” situation in which the main trunk of the “Y” is curbed and contains all the water for the three storms I’m studying. Runoff flows towards the two streets that branch off. I need to know what percentage of runoff water splits during the 2-, 10-, and 100-year storms from the main (curbed) roadway to the other two streets - one curbed, one uncurbed.
I assume that velocity, runoff volume, storm intensity, street cross sections, slopes, and other variables play a big role in how the water diverts, but I’m not sure how to set up this scenario in SSA. Do I somehow use a weir? Do I use an open channel, or user-defined channel? I have a subbasin area defined with my concentration point at the end of my main curbed street before the water splits off. I’m not sure where to go from here when it comes to inserting links, weirs, channels, etc.
how I can set this up? I’m not even sure it’s possible to have the software provide this type of calculation.
I am looking to calculate the volume of an existing berm from a TIN surface. I have read through some of the Civil 3D tutorials, and realize that I will need to have two surfaces (base and comparison), but need to figure out how to create the comparison surface.

View 3 Replies View RelatedI'm working with TIN surfaces, doing cut/fill comparisons for a surface mine.
My volume surface statistics show a cut volume of 5167.22 cy and fill volume of 8456.18 cy.
The sample line group volume report show cumulative cut of 5527.67 cy and fill of 8465.56 cy.
What could be some causes of this disparity. All reference surfaces are built from points and use a non-destructive boundary.
I've read a few threads on this way back but cannot locate them. I have two surfaces and create a volume surface and it reported the volume as 493 cy. I then ran some sample lines at 25 foot interval and the total volume is reported as 964 cy.
View 1 Replies View RelatedI want to use it as my primary hydrologic and hydraulic modeler. It only makes sense. Well, I got the program to work and had things linked in and was able to route a storm through the network. But when I routed the storms, I had to model double the storage that i expected.
So I went back to the program I'm familiar with - Pondpack by Benltey - and designed the same system I routed in SSA in that program - and got the storage volume that I would expect for a site of this size - about 2 acres.
Is there possibly a setting that I'm missing that makes my outlet structures route slower or less than they should? Or is there some other reason that a system would give this kind of inflated need for storage?
I have an issue with using Bounded Volume or Adding a Boundary to Volume Surface things so bad... = incorrect volumes.. sometimes extremely incorrect.. I understand that the surface rectangle when a boundary is added but this could be horrible if not checked.

I have a manure storage pond that I am trying to figure out the total storage volume for. It has 2.5:1 Side slopes and a 10 foot wide ramp at 10:1 entering the pond to the floor bottom. I am trying to figure out what the volume of this pond is. What is the fastest and most efficient way to get this volume? I do not want it compared to any other surface such as existing ground.
View 7 Replies View RelatedI have a surface and i have the outer border of a pond i want to create (see attachments). What makes it difficult for me is that different areas of the pond have different slopes. The area marked as "A" has a slope of 1:5, the are has a slope of 1:2 and the rest of the pond has a slope of 1:1.
My problem: I do not know how to grade the borderline so i end up having a surface with different slopes as my pond.
I have a surface built for the bottom of a pond. The way to get the surface area (not the volume) of the bottom of this pond?

I inserted elevation points at an increment of every 3 ft., which should make a smooth arc of contours around the pond.If the issue was resolved by this method, please click on "Accept As Solution".
View 9 Replies View RelatedI am designing a retention pond in an existing surface. I set the base of the pond and execute the grading at the desired slope and it generates the pond just fine, with the exception of rounded corners. I need the corners to be square, mitered corners instead of the round.
I'm using Civil 3D 2013.
I created a Pond Grading object with the associated surface. How can I cut and plot Section Views of the Pond Grading object just as I could do(using "Create Multiple Section Vtews" command) with Corridor object of a Linear project?
View 2 Replies View RelatedAfter crating my squared pond (or waste landfill for that matter) I runned a cross section from an alignment running across the the entire pond. The cross section did not show the bottom of the pond. I noticed that I forgot to do an infill to the bottom of the pond so I did it. But, still the bottom of the pond its not showing up in the cross section, just the side slopes. Do I have to delete the alignment across the pond and recreate it? That is probably the only thing I have not done. BTW, I have an access road coming down the side of the pond with a corridor created already and is not showing up neither on the cross section.
PD: I am running Civil 3D 2012!
I have a small site where i've essentially designed a storage pond. I've cut 3.0m off the original ground at a 2:1 slope and built a berm at a 2:1 fill slope to a designed elevation. I've managed to balance the site to zero. The contour drawing I have shows elevations - which is great - however the client has asked to see the contours showing a Fill or Cut label from the original ground.

We work on landfills that need stormwater control terraces and letdowns. It occurred to me to ask if there is some way to modify the water drop trace function (which examines a surface and determines the 90 degree to contours path) so that you could specify an angle to the contours of your choice. This would basically automate finding the flow path of a diversion berm. Any method of laying out, for instance a 2% flowline along a 3to1 slope or tougher yet, a face with variable slopes.

We have a long corridor that we are upgrading, and along this corridor, we have various water course passing through. We are replacing the existing culverts. They are large circular culverts. How do we show the culverts on our model? Do I create a short pipe network for each culvert crossing? And also, how do I daylight to the outside of the culvert as the corridor crosses over it?

Every time I go to use the water drop tool on a surface I have to change from the default layer 0 to my 'water drop' layer. I'm sure there must be a way to change it but I couldn't seem to find it in the surface styles...
View 3 Replies View RelatedOriginal intent was for daylight to have 4:1 slope and keep within the R/W. This causes some areas to hold water as shown circled in the image. I know I should be able to give it parameters or targets to avoid this.

Surface does exist as we can see the triangles/contours or whatever we choose to display. When we run the Water drop command, we are getting a message saying that the point is outside of the surface. We have selected a valid surface by both picking it visually and selecting it from the dialogue. All layers are on and thawed and we are picking well inside of the surface.
Why it would be telling us that the point is outside the surface?
i'm jumping into 3d late in life...playing with volumes. i've created surfaces from aerial surveys and have saved the surfaces as separate files. i would now like to run volumes of the two as they represent the same quarry site from different years. it appears (?) i need to have both surfaces listed in prospector to run volumes. each separate file has its own surface listed. question...how do i get (import?) the second surface drawing into one of the files so i have both listed and can run volumes? i see where i can create a surface from importing a .tin file...but i don't see how to export the surface as a .tin file.
