Formatted abstract
The purpose of this report is to evaluate the effectiveness of using high-resolution digital stereo-photogrammetry to measure erosion and apply surface recognition technology to determine the  spectrum of particle sizes. They key advantages of digital stereo- photogrammetry and topographic  recognition technology is their efficiency in effectively capturing three-dimensional surface data.  With the aid of mapping software, 3D models can be developed and utilized for various aspects in  geotechnical analysis. Photogrammetry has the capability to efficiently capture data for analysis  from large areas using high-resolution digital photographs. With its increased level of efficiency it is ideal for application on large surface areas such as rehabilitated landforms concerning to  evaluations of cost effectiveness, land stability, vegetation, and compliance with regulations. 

In this thesis the project aims and objectives are defined as:

  a) Investigate and obtain results on soil volume losses from high-resolution digital  stereo-photogrammetry and compare these results to those of previous studies.

  b) Investigate the relationship between surface textures and various slope locations through the  analysis and interpretation of computed particle size distributions.

  c) Compare and contrast particle size distributions of laboratory samples against processed  photography data, and determine the relative accuracy of the visually computed particle size  distributions.

  d) Briefly breakdown and determine the extent of human input effects on computer results and  program outputs.

  e) Investigate and compare the surface particle size distributions to the recorded results of  Bawden & Keighley (2001), and Aronis & Barnes (2007).

The first step in achieving the objectives of the thesis was the acquisition of collected and analysed data from previously designated slopes in past theses. Using the information, a time based comparative erosion measurement could be formulated and erosion effects evaluated.    ............................
