I am looking at a utility plan from the early 1900s, and there is what is called out as "10' CC Sewer" shown on the plans. This "pipe" has an invert depth of greater than 50-feet. There are no structures visible anywhere on the plan sheets that I have.
Does anyone know what this could be? This...
I am trying to model the spread of water overflow from a tank that occurs over a period of time.
The scenario I have is this....this tank overflowed for approximately 16 hours, at an estimated rate of 1.65 cfs.
I'm trying to estimate the probable extents of this overflow on the surrounding...
I am curious as to your thoughts on a situation.
An agreement was made between and Prime and Sub (verbal only via telephone) to team up for an upcoming proposal. After discussing strategies, planning an approach, etc., the sub decides to pursue this project on their own as a Prime.
Obviously...
I am trying to model a chamber in HydroCAD that utilizes a combination of gates and pumps.
The scenario is this:
Gate is open until elevation 100, at elevation 100 gate closes and pump kicks on, at elevation 105 pump turns off and gate opens back up.
Any help or ideas would be appreciated. We...
All these years I've never used HydroCAD for Rational Method!
So anyway, I downloaded a NOAA IDF Curve, following the Help Menu, and the IDF Curve shows up when I click "View IDF" under Calculation Setting>Rainfall but it doesn't seem to be loading. I can not get the red bar "IDF File not...
I would like to model a trapezoidal channel with three sequential check dams.
I am using this BMP for peak rate and volume control.
Channel Slope = 0.06 ft/ft (average of the three)
Width= 2 ft
Sides = 4:1
Depth = 2 ft
Height of Check Dam = 1.50 ft
Section L = 90 ft; 180 ft; 180 ft (upstream...
I am working on a few intersection improvement projects (widening, turning lanes, etc), and I am trying to come up with an approach for SWM.
These improvements are all occurring within populated (developed) areas, and any ROW I need will be taken from the individual property owner. That being...
I'm having a problem with StomCAD V81 (SS 4) with creating a drop structure.
The calculated pipe slope is going from bottom of box > bottom of box, regardless of the inverts I input.
I have the boxes and conduits set to "false" for design.
Default Design Constraints are set to "allow drop...
Any ideas or thoughts on how I could model a stone wick separating a forebay and the primary infiltration basin?
I really need to somehow show this as a broad-crested weir, that has a 40% void ratio from bottom of basin to crest.
I am working on a raingarden lined with an impermeable liner, with 4' of ammended soil (peat/organics) above the liner.
Bottom elevation = 100
Primary outfall 8" PVC = 100
Top of ammended soils = 104
Riser pipe = 104.50
Berm = 106
The calculations use an exfiltration rate of .5"/hr above...
