Software
Overview
Our team has designed a Eutrophication Management App in order to
elaborate on the topic of eutrophication and raise public awareness of
this worldwide aquatic issue. We utilized Xcode and Swift with the
connection to Firebase Console Authentication to build the application. In
this page, we will examine two major features, the calculation of the
severity of eutrophication and the status of eutrophication in Taiwanese
reservoirs.
Feature 1: Calculation of the Severity of Eutrophication
Our team determines different water qualities based on their respective
concentrations of phosphorus and nitrogen. We referred to the Vollenweider
index (Fig. 1) and calculated the most applicable range of water qualities
(Fig. 2). The standard is divided into three categories: oligotrophic,
mesotrophic, and eutrophic from the spectrum of lowest to the highest
concentration. We built a user interface where the user can input the
concentration rate of nitrogen and phosphorus. Subsequently, the system
will calculate the scale of eutrophication and return it to the user. This
will certainly give the audience a better understanding of the water
quality and concepts of eutrophication.

When the user input certain values regarding the concentration of
phosphorus and nitrogen, the system will return the index of
eutrophication (mesotrophic, oligotrophic, eutrophication, or no eutrophic
conditions)
Feature 2: Taiwanese Reservoir Map of Current Eutrophication Status
We constructed a user interface with a Taiwan map and annotated the major
reservoirs on the map. When the user taps on the annotated reservoir, the
software will provide information about the basic information and
eutrophic status of the certain reservoir. In the same token, we operated
the scale of eutrophication based on the aforementioned standard. By
viewing different reservoirs, the audience can clearly understand the
current eutrophication status in Taiwan.
Fig. 2 A particular reservoir’s background and status of eutrophication
are displayed when the user clicks on a major reservoir on the map.
Future Plan: The Implementation of Arduino Chip
For the future enhancement of the software, we hope to append a third
feature to connect with the Arduino chip. By operating different
conditions of the chips and implementing modules to connect with the
application, the users can change the filters when they receive the
message from the sensor of GFP and mCherry. The users can also monitor the
conditions of the chip at any time, operating the experiment with a more
precise procedure.
