The document discusses a water level monitoring system using LabVIEW developed by a group of students to enhance flood preparedness in Marikina, Philippines, in response to disaster management needs. It highlights the system's accuracy, independence, and alignment with flood alert standards, aiming to reduce casualties during heavy rains. The research underscores its significance for students, residents, local authorities, and future researchers in managing flood risks more effectively.

2. Introduction
 Marikina officials together with the National
Disaster Risk Reduction Management Council
(NDRRMC) made a way to prevent the flood
casualties.
 Philippine Disaster Risk Reduction Management Act
• enhances the disaster preparedness and capabilities of the
national government and local government units
 Water Level Monitoring System using LabVIEW.
• More accurate
• More independent
• aligned in the standards of the Flood Alert Level Monitoring
in Marikina River

3. Statement of the Problem
The problem is, due to the lack of
awareness of the abrupt increase of water
caused by heavy rain, most families fail
to make a quick response with regards to
the flood.This scenario causes
devastating effects such as deaths and
infrastructural casualties.The researchers
would like to resolve this common
situation during storm surges.

4. Significance of the Study
 1.To the Students
• For future proposals and studies concerning operational
systems integrated to LabVIEW Programming.
 2.To the Residents
• For their safety and security purposes that may reduce future
casualties
 3.To the Authority
• for them to take into account the rise and fall of the water level
and relay the information to their respective subordinates to
prepare and evacuate as needed as possible.
 4.To the Future Researchers
• used as their reference in terms of creating the same prototype
to achieve more empirical and experimental results.

5. Review of Related Literatures and
Studies
 Related Literatures
1. Badilla (2008), developed a simulation of river
flows in the Upper Marikina, based on linking
the HBV rainfall-runoff model with the DUFLOW
1D unsteady hydraulic model.
2. Soon after Tropical Storm Ondoy, Abon et al.
(2010), developed a hydraulic model of flow in
the Marikina River.Their semi-distributed model
combined the SCS Curve-Number loss model
with the SCS Unit Hydrograph, using the HEC-
HMS modelling environment.

6. Review of Related Literatures and
Studies
Related Studies
1. Flooding is the most common natural disaster
worldwide which happens without any prior
warning. Floods have been known to do some
significant damage. (Subramaniam, et. al.,
2010)
2. According to Mani, N.,et al., (2014), in the last
few decades several monitoring system
integrated with water level detection have
become accepted.

7. Methodology
Process
• LED indicators
• Sonic Range Finder
• medium-sized aquarium
Front Panel
Block Diagram
Actual Set up

8. Conclusion
 The researchers used the aquarium and miniature.
Once the sensor detected the level of the water, the
corresponding LED will blink. It uses three LED
indicators with respective warnings.
 The levels set in Virtual Instrument during the testing
experiment are scaled.The first level was set from 0-7
inches.The second level was set from 7-8 inches. And,
the third level was set from 8- above inches.
 The amount of casualties in flood-prone areas will
decrease through the use and implementation of this
project.
