What is TDT?

Terrace Design Tool (TDT) is a software tool designed to assist field office staff and engineers to design erosion control terrace systems for conservation projects consistent with national conservation practice standards Code 600 Terrace and Code 638 Water and Sediment Control Basin.

TDT is a plug-in component that operates seamlessly with the Engineering Field Tool framework and takes advantage of previously developed components and applications such as the Survey Engineering Tool (SET).  More specifically, it can use SET's survey and alignment tools, TIN engine, cut/fill volume calculation engine, waterway design tools, earthworks structure design tools and reporting framework.

TDT benefits field office staff and engineers by consolidating knowledge and practices in the form of an easy-to-use tool for design of terrace systems. TDT benefits the end customer, the citizens and farmers, by assisting in implementation of properly planned conservation projects for the land.
