Description
Week 1 - Assignment 1
Stream Morphology Laboratory
[WLO: 1] [CLOs: 1, 3, 5]
This lab enables you to construct a physical scale model of a stream system to help you understand how streams and rivers shape the landscape, and how human actions can affect river ecosystems. This lab is done with materials that you will need to supply; the list of items you will need to obtain is in the Stream Morphology Investigation Manual.
The Process:
Take the required photos and complete all parts of the assignment (calculations, data tables, etc.). On the “Lab Worksheet,” answer all of the questions in the “Lab Questions” section. Finally, transfer all of your answers and visual elements from the “Lab Worksheet” into the “Lab Report.” You will submit both the “Lab Report” and the “Lab Worksheet” to Waypoint.
The Assignment:
Make sure to complete all of the following items before submission:
- Before you begin the assignment, read the Stream Morphology Investigation Manual and review The Scientific Method (Links to an external site.) presentation video.
- Complete Activity 1 and Activity 2 using the materials that you supply. Photograph each activity following these instructions:
- When taking lab photos, you need to include in each image a strip of paper with your name and the date clearly written on it.
- Complete all parts of the Week 1 Lab Worksheet and answer all of the questions in the “Lab Questions” section.
- Transfer your responses to the lab questions and the data tables and your photos from the “Lab Worksheet” into the Lab Report Template.
- Submit your completed “Lab Report” and “Lab Worksheet” through Waypoint.

Introduction
Question One.
It is imperative to bear that stream morphology comprises of the topographies which
form beside the course of a river as it streams down. It gives the aptitude of constructing a
physical scale model that enhances a comprehension on the way watercourses act to shape the
landscape and also the way human activities impact on river ecosystem. Stream morphology
comprises of a flood plain, watershed, river deposition, erosive activities as well as all the
streamflow features. Streamflow features comprise of discharge: the quantity of water that flows
past a particular stream position. The intensity of corrosion relies on a river’s velocity as well as
the difference in relief that is a result of gradient variance (Environmental Science Manual,
2016). Features which are created from erosion comprise of meanders which mostly are an
indication of sinuosity.
Question Two.
The essence of this report is to aid in understanding the way human actions as well as
activities can affect river ecosystem. On the other hand, this report will be essential in facilitating
comprehension of how rivers shape the scenery. Moreover, it helps in comprehending various
physical features which are created along the river course as a result of these activities. The
features comprise of oxbow lakes and meanders. Nevertheless, it provides knowledge of
analyzing various morphological features of rivers. On the other hand, the report enlightens on
how to calculate river sinuosity velocity, relief as well as river discharge velocity. Last but not
least, the report will be essential in understanding the relief hypothesis, gradient hypothesis,
sinuosity hypothesis and velocity hypothesis. The theoretical data therein will be essential in
analyzing the factors which result in the establishment of these features

Question Three.
The hypothesis for activity one
We have several influences which affect sinuosity velocity. To begin with, the angle of
slope of a river bed impacts on sinuosity speed. This is due to the fact that when the river bed is
slanted at a sharper angle, the great...
