    InRoads Reports - xsl Stylesheet Editing

    Thanks, Bob. This is for the NJDOT. I have a lot of electronic files from them and haven't noticed any .xsl in the group, if that is what you mean. I understand that almost any software will edit the XSL or XML. But that is assuming you already know what you're doing as far as XSL/XML...

    InRoads Reports - xsl Stylesheet Editing

    I've got to put curve tables into a MicroStation file for the DOT. They need to be in a specific format. None of the stylesheets that come with InRoads out-of-box quite have what I need. They are close, and probably just need a small amount of editing. I have had limited success, but I...

    InRoads - Generate Front/Top of Curb Feature

    I subsequently realized that the creation of the temporary graphic offset at 3 feet into the street is unnecessary. If you simply use the back of curb feature as the primary and secondary, InRoads knows what to do. It doesn't need them to be two separate items. And it is cleaner with the...

    Puzzled about basin outlflow results

    "Water will discharge through an outlet even if there is no storage at that elevation", does not make any sense whatsoever. It absolutely should NOT discharge anything if there is nothing there stored to be discharged. The storage table determines the elevation of water at the inlet of the...

    InRoads - Generate Front/Top of Curb Feature

    mechamb, the problem I have with what you suggested is that I do not want the top of curb feature to be 0.5 higher in elevation than the gutter. This is not accurate; this is an estimate of something for which have surveyed data...Defeats the purpose, doesn't it? The surveyor has given me a...

    InRoads - Generate Front/Top of Curb Feature

    Here's the issue: Our surveyors, and most I've worked with, bring back survey for curbs by giving two lines: one represents the gutter line, one represents the back of curb. Assuming the front of curb is the same elevation as the back of curb, I always have to generate another offset feature...

    TR-55 Sheet Flow limit

    Always remember also, that the concept of sheet flow is violated for flow depths greater than 1" or 0.1'. I tend to look at a square area in sheet flow and use manning's equation on the flow to check that its depth has not gone too deep. For instance, take a square cross-section that is one...

    Encroachments in Hec-Ras

    Yup. The manual makes it seem like the program can do this efficiently, but I found that I had to manually set a lot of my encroachment stations. Even found that bringing the stations in closer to one another, made the resulting elevation get lower! I would move on to the next one, set that...

    NJ FHA Regs

    Much earlier than that. I have the Technical Manual for Stream Encroachment Permits dated December 2008 that reflects this. The old regulations were vague in how to determine the effects of future development. So Vince Mazzei and the NJDEP used the 25% to account for this.

    HEC-RAS veloctiy profile

    1. It is measured from d/s to u/s always. So, this is your value in the reach length column on your geometric data window for each cross-section (XS). XS 8 should have 0 as the reach length because it represents the distance from XS 8 to the next d/s section. Since XS 8 is the most d/s...

    HEC-HMS Deletes Data Table

    Sorry about the misinformation - HEC-HMS is up to 3.4 now.

    HEC-HMS Deletes Data Table

    Very strange. Are you using the paired data manager to create this table? Then going to the components tab to enter the data? Or maybe the first question should be what version are you using? They're up to 3.3, which is nice - now includes DelMarva DUH.

    Pipe Depth of Flow

    You can easily use goal seek in excel. No macro needed, but my way would be a one-by-one calculation - not a batch calculation for a long list of pipe. Basically, you are putting manning's equation in one cell, with references to other cells for n, R, and S. You'll need R as a function of...

    How do YOU design storm sewer?

    I recommend InRoads Storm & Sanitary also - but it has the best advantages when your roadway guys are modeling using InRoads. It is very easy to see conflicts, check cover, etc visually. When I first used it, I checked it against my spreadsheet and the answers are identical - not just close...

    Is this possible in HEC HMS?

    The quick answer is no. This would have to be done with two seperate runs. One run can only have 1 each of basin model, meteorological, and control. You could possibly change your loss or transform method for some of the subbasins to model the differing effects. Other than that, I do not...
