This document is a terrain mapping report for an academic exercise conducted by Richmond Ho Shing Yu. The report summarizes Richmond's terrain mapping of the Valleyview area in Kamloops, BC from an aerial photo. Richmond conducted field surveys of two locations - Juniper Ridge and near the Valleyview arena. At these locations, Richmond observed materials such as till, colluvium, and glaciolacustrine deposits. Richmond also noted geomorphic processes including gullying, piping, and slopewash. Richmond then created a terrain stability map of the area using symbols to represent surface materials, landforms, and geological processes observed.

The study was carried out using the UAV for analyzing the characteristics of debris in order to present the methodology to estimate the quantitative amount of debris caught in small river facilities. A total of six small rivers that maintained the form of a natural river were selected for collecting UAV images, and the grouping of each target in the image was carried out using the object-based classification method, and based on the object-based classification result of the UAV images, the land cover classification for the status of factors causing the generation of debris for six target sections was carried out by applying the screen digitizing method. In addition, in order to verify the accuracy of the classification result, the error matrix was performed, securing the reliability of the result. The accuracy analysis result showed that for all six target sections, the overall accuracy was 93.95% and the Kappa coefficient was 0.93, showing an excellent result.
What is a Shoreline Management Plan?
Developed in partnership by local authorities, regulators and other stakeholders, a Shoreline Management Plan (SMP) is a high level non-statutory policy document designed to assist coastal flood and erosion risk management planning. It provides a large-scale assessment of the risks (to people, property, the natural and historic environment) associated with coastal erosion and flooding at the coast over the long-term. It also proposes policies to help manage these risks sustainably over the next hundred years.
The SMP enables planners and regulators to plan for and manage the way that the coast will change. This could be by maintaining or improving defences, by enabling the natural processes to play a greater role, creating new natural habitat or by helping areas that are at risk of flooding at some point in the future to cope with and limit the impact of flooding events.
The SMP2 for the Severn Estuary updates an earlier SMP1 (2000) for the estuary. It aims to provide more certainty for landowners, residents and businesses; to know how the coast will be managed by regulators during the next 100 years, so that they can plan ahead and make decisions about investments, homes, development and the management of their resources.

Scope
Geog 3200, have appointed Richmond Ho Shing Yu to perform terrain stability mapping,
terrain stability interpretation, field surveys, terrain and field description of the Valleyview
area in Kamloops, BC, Canada (Figure 1).
The terrain stability mapping and terrain stability interpretation is being commenced on an
air photo retrieved from GeoBC, Airphoto Viewer via Google Earth. The following
information provides the information about the air photo:

Terrain Stability Map
Terrain Stability Mapping Methods
The method of terrain stability mapping, is being computed by stereoscopic observation of
an air photo. In this project, the air photo that is being chosen for stereoscopic observation
is an air photo retrieved from Google Earth. The scale of the air photo is a digital copy that
is approximately 1:20000 scale, taken in 2011-07-06.
The method of terrain stability mapping, is carried out by polygons in the terrain stability
map. A polygon is a unit that is expresses an area with similar surficial matter, geomorphic
process, and slope stability. In order to map out areas of similar landforms, symbols is
being applied to display the geological features of a certain polygon.
Terrain Polygon Variable
The size of polygon is being mapped at a scale of 1:29,000 map, the smallest appreciate
polygon size of this project is set to 0.5cm x 0.5cm. Therefore polygons that is less than
0.5cm x 0.5cm will not be evaluated.
Within a polygon in the terrain stability map, terrain symbols within a polygon indicates an
area with similar terrain characteristics. Symbols used within the polygons follows the
guide of “Terrain Classification System For British Columbia 1997 Version 2” by
“Fisheries Branch, Minister of Environment, and Surveys and Resource Mapping Branch
Minister of Crown lands Province of British Columbia.” The guide offers directions and
symbols about the surficial material, surface expression, and process in classifying
polygons in the terrain stability map.
Terrain Stability Interpretation
Terrain stability interpretation, is the process of describing steepness of the slope in a
polygon. In order to depict steepness of various slope in the studied map, slope are being
classified into classes ranging from, plain, gentle slope, moderate slope, moderately steep
slope, slope and steep slope shown by (Table. 1). In general terms, these slopes shares the
common a characteristics in unidirectional surfaces that can be either be straight, concave
or convex. Slopes appeared in terrain map maybe over exaggerated or distorted.

Surface Materials
Surface Material
According to “Terrain Classification System For British Columbia 1997 Version 2”
contributed by “D. E. Howes and E. Kenk”. Surficial materials are being defined as “non-
lithified, unconsolidated sediment” that are produced by various activites like weathering,
erosion and many more process parent material.
“Surficial materials are defined as non-lithified, unconsolidated sediments. They are produced by
weathering, sediment deposition, biological accumulation, human and volcanic activity.” (Howes,
Kenk, 1997).
Throughout the survey, there are various types of material are being identified in different
locations. Different types of material reflects the geological history. The following surface
material found in surveyed sites and observing air photo. It is suggested that, Valleyview
was located on the floor of a glacial lake.
Glaciofluvial (FG
)
Glaciofluvial sediments is a glacial material that is made up of sands and gravel,
transported by glacial melt water. Glaciofluvial material is can be found in terraces above
river level.
Fluvial (F)
Fluvial material, is a type of material that is made up of sand and gravel, deposited and
transported by river discharge. Likewise, the process that transport fluvial sediment may
include, deposition and transportation includes solution, suspended sediment transport and
bed load transport that occurs in active floodplains.
Colluvium (C)
Colluvium are material that are transported down slope by mass/slope movement, due to
earth’s gravity. Material in colluvium may vary from till, bedrocks and other materials that
can be found on slopes. Colluvium materials may be found in process of mass movement
motions like, avalanching (ice/snow or sand/dust), toppling or falling.
Till (M)
Till is a material that is deposited by glaciers. The characteristic of till consist of
unconsolidated, unsorted, matrix supported clast that consist of a mixture of clay, sand and
sand matrix.

Glaciolacutrine (LG
)
Glaciolacustrine are material that is deposited into a lake ice the presence of glacial ice; for
example sediment of ice dammed lakes. This sediment consist of sand, silt and clay.

Terrain Discerption
Interior Plateau of Kamloops
Kamloops is an interesting area that is composed of varieties of geological materials.
According to a brochure, published by the mystery of Kamloops, “GeoTour Guide For
Kamloops, British Columbia”, written by “R.J.W Turner, R.G Anderson, M Cathro, C.
Huscroft, E. Frey and K. Favrholdt.” The timeline of Kamloops’s geological history can be
described in the following:
1) Limestones, mudstone and volcanic rock, that are found on top of glaicalfluvial
sediment and terraces, have suggested that Kamloops was once located under the
sea floor.
2) North American tectonic plate pushes the seafloor and volcanic westward, as the
Atlantic Ocean began to open. This causes the plates to collide with each other.
3) As the North American tectonic plate pushes the Atlantic Ocean plate westward, it
causes formed mountains.
4) Volcanoes eruption forms plateau. This is where volcanic deposits covers the
mountains landscapes of Kamloops
5) Ice Age arrives to Kamloops, this is where ice sheets carved modern valleys.
6) The end of Ice Age caused glacier ice to melt. Potentially melted ice water form
gullies, and glaciolacustrine sediments.
7) Glacier have completely melted, this is where rivers carved the present landscape of
Kamloops.

Mass Movement Description
Colluvium Flow (f)
Colluvium flow is a type of mass movement, which transports ranging from rock, soil, debris,
and earth material downslope, by over saturation of pore pressure in soil. Moreover,
colluvium flow produced colluvium “fan”.
Piping/Sub Surface Pipping (P)
Piping is mass movement that is related with sinkholes. Likewise, both geologic phenomenon
occurs in area of fine silt, and sand. This is where over saturation of pore pressure in soil
causes a downward collapse of material in a vertical void.
Gullying (V)
Gullying is a rectangular, V-shaped landform, with deep head scarps. The process of gullying
involves movement of water; this is where high volume of water cuts and form drainage
channels.
Washing/ Slopewash (W)
Washing/slopewash, is a type of mass movement that transport material by
flowing water down slopes.
