Abstract
The most hazardous type of floods are flash floods,
which combine the devastating force of a flood with extremely high speeds. This
project entails creating a flash flood warning system that can identify floods
and instantly notify drivers plying Nkpolu Road in Rumuigbo, Port Harcourt,
using a mobile device. Soil samples collected from Nkpolu Road were transferred
to the laboratory and examined, along with rainfall data collected from the
Nigeria Meteorological Agency (NIMET). On the basis of the examination of the
soil samples and rainfall data, the measurement apparatus was constructed. The
HC-SR04 ultrasonic sensor, the SIM900L data transmission module, the DFRobot
gravity pH sensor, the SHT20 soil temperature/humidity sensor, and the Arduino
microcontroller are all integrated into the system. According to the analysis,
the soil types on Nkpolu Road are sandy loam and loamy sand, and the intensity
of the rainfall is often highest between July and September. The analysis's
conclusion indicated that the road experienced flash floods because of the
heavy rainfall and the soil's limited capacity to hold water. As a result,
water runoff was heavy, particularly in July and September. When the system was
installed on Nkpolu Road, it could detect flash floods when it rained and could
send out warning alerts via a mobile device every six minutes. The alerts would
first say "no flooding," but as the rain got heavier, they would
change to "minor flooding," "moderate flooding," and
finally "severe flooding," sending out warnings in real time as soon
as each level of flooding was identified. "No flooding" was the
warning issued on the day it drizzled. There was no warning signal issued when
it did not rain at all. This system developed help road users on Nkpolu road to
avert the road when flooded and use other available routes in real time.
