This document summarizes a student project analyzing stream hydrology. It includes sections on the water cycle, watersheds, motivations from different fields of study, techniques for mapping contours, channel lines, flow direction, outlets, and floodplains using CAD software. Maps were created showing stations along the waterways, floodplain boundaries, and references were provided. The overall goal was to model and map key hydrological features and flooding impacts for an engineering analysis of water infrastructure and sustainability.
2. Introduction to Hydrology
● The water cycle
○ Continuous movement of water
○ Humans and their effects on the water
cycle
● Watershed and drainage
○ Watershed: Area of land that drains into
a stream
○ Drainage area: Allows for water volume
predictions

3. Motivation
● Our areas of study analyze water
○ Civil Engineering - the battle between
infrastructure and nature
○ Biosystems Engineering - a sustainable
means to find a solution, pollution
○ Ex. permeable pavement

4. Contour
● Rough draft imported
○ Traced over
● Index contours
marked and bolded
● Peaks, depression,
and saddle marked
5. Channel Line
● Made using Polyline
● High to low elevation
○ Through “V’s” in
contour lines
6. Direction of Flow
● Qleaders along straight
lengths
○ Arrow size changed
● Text rotated
○ Background mask
on
7. Outlet
● 12 ft. diameter circles
● Text with background
mask on
8. Main Channel
● Normal capacity of
channel
● Channel lines offset
by 5 ft.
● MUDST hatch
○ Scale of 80
● Trimmed and
extended
11. Station-Station Hydrograph
● 24 stations total across both
waterways
● Represents water surface
elevation of flow at a given
time
12. Stations
● 24 stations along 2 channels
● Changed point size
● Made using the channel length
and Measure tool
13. Station Angles
● Helps to establish
Floodplain Boundary
● Created by making 90
degree lines off channel
line and using the
Station-Stage Hydrograph
14. Stations and Lines
● Shows each line for the
floodplain with individual
station label
16. Floodplain
● Defined by the dry, flat area
adjacent to the river, stream,
or lake
● Determined via delineation
● Areas and lengths shown
● Hatch is GRASS
○ Scale of 70

Editor's Notes
A picture of the rough draft was imported into AutoCAD and traced over to create the contour lines. The index contours are labeled and bolded with a 0.50 mm lineweight. The peaks, depression, and saddle are marked with tick marks signifying the depression, two peaks in the lower half of the picture showing a saddle, and one peak in the upper-middle half of the image.
The channel line was made using polyline commands going from high elevation to low elevation and through the bottoms of the “V’s” of the contours
The direction of flow shows the flow of the channel and it is shown using qleaders along the straight lengths of the channel line with arrow size changed accordingly. The text was rotated to be parallel with the channel line and has background mask on to be seen over the contour lines.
The outlet shows where the water would exit the channel and is indicated by a 12 ft. diameter circles at the downstream ends of the channel lines. The text was added with background mask on and qleaders were used to connect the text to the circles.
The main channel is the normal capacity of the channel. In the drawing, the main channel lines are 5 ft. offsets of the original channel line and are trimmed and extended to the boundary. The area was hatched with the MUDST hatch with a scale of 80.
The bankfull is the maximum capacity without overflowing. In our drawing, the bankfulls are 5 ft. offsets of the main channel lines and are hatched with the GRAVEL hatch with a scale of 100. The bankfulls were trimmed and extended to the boundary.
