TS 5449

TS 5449 is a terminology standard for drainage and soil reclamation, bringing together the terms and definitions used in this technical field. Standards of this type help ensure that engineers, agronomists, and researchers use the same concepts in the same way, especially when discussing land improvement, water removal, and the preparation of land for productive use.

What the scope includes and excludes

The standard is limited to drainage and soil reclamation terminology. It explicitly excludes terms and definitions related to soil, soil studies, soil conservation, irrigation, fertility, and fertilization. That distinction matters because drainage focuses on the control and removal of excess water, while soil reclamation addresses broader measures to improve land conditions. As a terminology standard, its role is to define the shared language, not to prescribe engineering design rules or field procedures.

Why terminology matters in this field

In general technical practice, drainage is concerned with managing surface water or groundwater so that land can function properly. Soil reclamation is a wider land-improvement discipline that may address problems such as excessive wetness, salinity, poor structure, or other limitations affecting usability. A clear set of terms supports design documents, site reports, training, and technical communication, reducing ambiguity when multiple disciplines work on the same land area.

This document was adopted in 1988 and later withdrawn. It therefore serves as a historical terminology reference for its subject area rather than a current operative technical specification.
