PREFACE

This is one in a series of training manuals on subjects related to irrigation that will be issued in 1985 and 1986.

The papers are intended for use by field assistants in agricultural extension services and irrigation technicians at the village and district levels who want to increase their ability to deal with farm-level irrigation issues.

The papers contain material that is intended to provide support for irrigation training courses and to facilitate their conduct. Thus, taken together, they do not present a complete course in themselves, but instructors may find it helpful to use those papers or sections that are relevant to the specific irrigation conditions under discussion. The material may also be useful to individual students who want to review a particular subject without a teacher.

Following an introductory discussion of various aspects of irrigation in the first paper, subsequent subjects discussed will be:

· topographic surveying
· crop water needs
· irrigation scheduling
· irrigation methods
· irrigation system design
· land grading and levelling
· canals and structures
· drainage
· salinity
· irrigation management

At this stage, all the papers are marked provisional because experience with the preparation of irrigation training material for use at the village level is limited. After a trial period of a few years, when there has been time to evaluate the information and the use of methods outlined in the draft papers, a definitive version can then be issued.

ABOUT THIS PAPER

Elements of Topographic Surveying is the second in a series of training manuals on irrigation. This manual describes elementary surveying equipment and provides examples of their application. It thus guides field assistants and irrigation technicians in setting out straight lines, measuring distances, setting out right angles and perpendicular lines, calculating surface areas, setting out horizontal lines, slopes and contour lines and measuring differences in elevation.
