eBook - Preliminary Dam Grading Analysis

PUBLICATIONS

In 2017 I authored and published the world's first dam grading manual. At nearly 300 pages, this book outlines through pain-staking detail a highly efficient method for producing small earthen farm dam construction documentation compliant with existing regulatory frameworks. 

The content is divided between five main chapters:

  • I. Introduction
  • II. Mapping
  • III. Grading
  • IV. Analysis
  • V. Output

Each chapter is broken down to the major and minor steps that guide the reader from the initial project brief and concept design towards the culmination of the output of all the various grading plans, reports and data exports.
