HidroTool provides a fast assesment toolbox for common hydraulics problems. It solves the pressure pipes flow, open channel flow, regime theory for natural streams and finally the sediment movement threshold. The Colebrook-White equation and Manning formula are implemented and solved focusing in different scopes, structures dimensioning, field data survey, etc.

The background idea is to provide a field tool able to solve desktop computations. Taking advantadge of the new mobile processors in possible to implement numerical methods in order to solve nonlinear equations. The powerful user interface of this devices simplifies the data input and increases the results presentation quality.
