Project Specifics
Swimming is a good way to determine the overall accessibility
of our rivers because it involves aspects of all river activities:
desirability, feasibility, and hazards. I identified a number
of indicators believed to determine the current state of each
of these three aspects. This data should be useful for other
people interested in fishing, boating, hangin out and waterfront
development.
I used an outboard boat to document 50 miles of shoreline along
the Allegheny, Monongahela and Ohio Rivers of Pittsburgh. I tried
to find every existing and potential swimming point within this
area. Locations were judged based on access to the river. Some
places would not be accessible to everyone if they required climbing
ropes or scaling steep slopes but I included them because they
do provide access for some. I recorded a GPS point, a photo and
an evaluation of indicators for desirability, feasibility and
hazards. It was not possible to swim at every location because
there are so many; instead, I chose a range of places to swim
and used my years of experience to judge the others.
I interviewed a number of people from a range of perspectives
to understand the different perspectives associated with the
rivers. The range included people who had never been near the
rivers, those who grew up near the rivers, those who have rarely
visited the river, fishers, boaters, people just walking near
the rivers, young and old. Between the recorded data, the interviews
and my own experiences with the river I was able to crack into
the current state of swimming in the rivers.
The recorded data was linked to the GPS points and photos through
GIS software. GIS generates maps to show the data layered spatially
which helps to find trends and locations of interest. I produced
a website and a printed equivalent. The website has a full report
of the different factors affecting swimming in the rivers as
well as maps that outline each of the 3 main aspects. Probably
the most important product on the website is the dynamic map
which lets users search all the sites I recorded for features
that they find attractive and view photos for each.
Understanding the indicators used to evaluate points of access:
Feasibility
These are the physical factors that aid or prevent access to
the water.
Berm and Bank Materials
Surface materials can hinder access and can also make the space
very nice. There is no rules as to which do what. For instance
cement can make a great access ramp but in some places it is
just dumped making the area very difficult to traverse.
Berm and Bank Angles
Flood planes and flood walls can have a great effect on the accessibility
of a site. Steep banks can be difficult both going up and down
however combined with some access structure such as stairs
the angle is a non-factor.
Structure
Most of the sites found in the study do not have constructed
access infrastructure which is what makes this study different
from others. It is not necessary to have a structure but they
can greatly increase the accessibility of the river.
Difficulty
There is no one indicator that shows if a site is easily accessed
or not however a combination of a few indicators is very accurate.
The values assigned to each site were determined based on the
other indicators.
Desirability
This aspect is the most overlooked. The river is naturally an
attractive place but there are many factors that determine
a specific locations attractiveness.
Setting
The character of a site is largely based on what objects are
present. This indicator classifies the overall set of objects
present.
Activity
What type of swimming that can take place a spot can change they
way it is viewed. An activity such as cliff jumping would not
be as attractive to older people as it would the kids.
Background
The space outside of the access point can affect the way people
feel within the space.
Campsite
A campsite adds a more lasting and homey aspect.
Waste
Unfortunately many generations of people have left things they
no longer need at the river and we have not cared enough to
clean up.
Description
Each site has something unique.
Usage
In some cases I have been around a site enough to know how often
it is used but for the most part one can tell based on what
was left behind.
Hazards
The river environment has a number of general hazards just as
any place does. Some access points have hazards beyond those
of the whole river.
Water
Water moving too fast is a danger, but water moving too slowly
can become stagnant and unhealthy.
Waste
Some things left behind are not just unpleasant, they are dangerous.
Ecoli Indicators
Our sewage system regularly overflows into the river. The sewage
will wash away but at some times it is not pretty. Ecoli is
often tested for and used as an indicator for those things
that are harmful to humans.
