Android Canal Design Software

First of all I want to apologize to those whom I've distributed my first android app during the training on Palawan, which is for designing of canals. It has a glitch on the part of computation for wetted area and wetted perimeter.
I missed to include the depth of water for the computation so there is an error although there are times that it
could be correct, I suggest that you delete that app and replace with this new one with the bug been fixed.

Here is the screenshot.

Instruction for use:
1. I think almost all of the fields are explanatory except one, the sideslope.
    If your sideslope of the canal is for example, 1.5:1, you have to input 1.5.

   - That's all after you enter a value for trial of base, press the "Submit" button.

One thing more, I created this android app to support android devices with version 2.2 and up..
