Topography & Drainage

ADMS's Topography module converts your topography points into a simple and useful format. There are also tools for removing unwanted data or poor quality data.

Collecting Data


It is recommended to collect topography data on 45' to 50' wide passes maximum width. Make sure you drive the ditch bottoms. Here is a view of imported data.

Topography Image


Topography imaging gives you the rise and fall within the field, but does not capture problem areas. This image is the backbone to all the watershed layers ADMS will create. The elevation image is the base for creating all of the other ADMS topography layers. The color relief image shows the highs and lows of elevation throughout the field.

ADMS Topography Layers



Watersheds


This layer shows all the water in an area that wants to flow to a common outlet. Every outlet will have an individual colored area of the field.

Flow Accumulations


Flow Accumulations show where water wants to flow in a field. More importantly these lines show you how much water is flowing to a specific outlet.

Depressions


The depressions layer displays the areas of the field where water is prone to standing. It shows you the areas that need work.

No more searching for those wet spots you saw earlier in the season. Note: The ditch bottoms were not driven so we get an angle ditch in the lower left corner of the field that has multiple depressions.

Hills


The hills layer displays areas of the field that have both slope and elevation and will generally shed water quickly.

Profile Tool


As part of the Topography package, the profile tool is very helpful in drainage planning. As you lay out your drainage paths you can see how much slope, cut and fill is required for that path. Very useful in ditch planning.

The light purple line in the middle of the field is represented by the profile line on the bottom of the window. There is also line information on length, drop, cut and slope.
