Quantification of coastal erosion alongSpey Bay and the Spey River usingphotogrammetry and LiDARimagery-derived DTMs

Coastal erosion has become an important phenomenon for all the beaches in theworld. There are many physical changes involved in the Coastal erosion. This paperis more concentrated towards the quantification of the coastal erosion andmovements of sediments along the beach. It tries to understand the volumetricchanges and Sediment movement along the Spey Mouth and River Spey. The thesisincludes the study of the changes along the beach and river over a long period oftime. The study area is located to the Northeastern part of the Scotland, UK. The areais located at Latitude 490N and Longitude 30W .The main purpose of this thesis work is to create the DTMs from the stereo imagesgot from the year 2000 using the software Socet Set 5.3. Then Orthophotos arecreated using the same software for further study of the Geomorphologic changesalong the Spey mouth and River Spey. The DTM and images derived from LiDAR inthe year 2003 are also used to study the changes. This research explains thephotogrammetrical methods used to generate the Orthophoto and DTM for theLower Spey River and Spey beach. Using the generated models in the GIS analysis tocalculate the volume and area change in the Spey area. This paper aims to visualizeand understand the changes in height that took place from 2000 to 2003.The main objectives of this project include the calculation of the changes in volumeof the Spey River and the Spey Bay Beach; generate the height changes in differentparts of the Spey area and to visualize the processes
