Whether modeling Culverts, Channels, Inlets or Weirs you will need at some  point to know the flow rate.  Hydraflow Express has options on the Hydrology section to help develop run off  Hydragraphs and it uses a variety of methods.  It supports the Rational method, Modified Rational method and the SCS method.  You might hear the term volume flow rate and think it sounds boring, but volume flow rate keeps you alive. I'll tell you how in a second, but first we should define volume flow rate. Let's look at these a little further,  to start off with we'll use the Rational  method and let's look at an example.  For the Area I'm going to use .4 acres, for the Runoff Coefficient I'll use .8.  For the Tc Method I'll select User, but we do have a number of other methods here as well.  For the time I'll set that to two minutes,  the Storm Distribution and Duration are the -0- options, which means I don't need  input anything here so I'll skip those,  and I'll accept the value of one, and the ...

Open Civil 3D - From  Analyze Tab, select the Design Panel Pulldown........   In Hydraflow Express the first task we'll take a look at is working with Culverts  and this is an easy-to-use yet sophisticated Culvert Modeler.     It also assumes that you have a good understanding of fundamental hydraulic  principles and the variety of flow conditions for Culverts.  Let's work through an example. Starting with data to input..... Now here we have the Input column and this  is where we'll input all of our values; and we can see if I pick the different  fields, at the bottom of the dialog box you get a description of the values that  Hydraflow is looking for you to enter. So I'll start at the top and for the  Invert Elevation I'll start by entering 100.  For the Length I'll enter 30, for the Slope .5 (for half a percent slope),  then you'll notice that the Upstream Invert  Elevation is automatically calculated for you.  I'll move on and enter the Rise and I'll start with 18 inches, and this is for an  18 inch diameter pipe. ...

Driving in 3 Easy steps....... Step 1 - Choose your vehicle Click AutoDrive Arc and the vehicle libraries are automatically opened. Choose your vehicle from one of the vehicle libraries In addition to worldwide design vehicles, you’ll find “European Vehicles”, “North American Vehicles” and “Specialist Vehicles”;  Click Proceed.   Step 2 - Position your vehicle You will be asked whether you want to set the current vehicle as your default vehicle for all future paths. Select either Yes or No. The Drawing Settings window will appear; here you can change your path settings and units to match the drawing. If these are ok, click Yes to continue. Position the front of the vehicle where you want it and left click to accept, then you can set the orientation of the vehicle to point in the direction that you need. The Position Vehicle Window will appear with more options if needed, simply click Proceed to start driving.   Step 3 - Drive your vehicle As you move the mouse around, the vehicle path is calculated based upon the vehicles dimensions and geometry. If a maneuver can’t be performed, AVT wont let you complete that ...
