Flooding and the Effects of Shearlines on Water Flow in Palawan, Philippines

Introduction

Palawan, known for its stunning landscapes and rich biodiversity, is also vulnerable to natural disasters like floods, especially due to its proximity to active geological zones. The Philippines sits on the Pacific Ring of Fire, meaning it experiences frequent tectonic activity, including earthquakes and the shifting of tectonic plates that create shearlines or fault lines. These shearlines can alter the natural flow of water, leading to increased flood risks in certain areas. This unit will explore the effects of shearlines on water flow and flooding in Palawan, Philippines. By the end of this unit, you will produce an in-depth report and an infographic explaining how tectonic activity influences flooding in Palawan and what can be done to mitigate these risks.

Task

Your task is to create an infographic and a detailed report that explains the effects of shearlines on water flow and flooding in Palawan. The project should include:

  1. Infographic: A visually engaging diagram or infographic that demonstrates the role of shearlines in altering water flow, with specific references to Palawan’s geological features.
  2. Written Report: A comprehensive report that includes:
    • An explanation of shearlines and their formation.
    • A description of how these geological features affect water flow and flooding in Palawan.
    • Real-world examples of flood events influenced by tectonic activity in Palawan.
    • Flood prevention strategies and how local communities can mitigate the effects of shearlines on flooding.
Process

  1. Research:

    • Start by exploring the geographical and geological characteristics of Palawan, focusing on the island’s location along tectonic fault zones.
    • Research how tectonic activity and the presence of shearlines in the Philippines impact local rivers, drainage systems, and flood risk.
    • Look for case studies or news reports on flooding in Palawan that may have been influenced by shearlines or fault lines. Pay attention to any historical floods that may be connected to seismic activity.
    • Investigate local flood control measures and how the government and communities in Palawan address flooding risks.

  2. Create the Infographic:

    • Use a graphic design tool like Canva, Piktochart, or Venngage to create an infographic that includes:
      • A brief explanation of shearlines and their formation.
      • An illustration of how shearlines affect local river systems and drainage.
      • Examples of flood-prone areas in Palawan influenced by tectonic activity.
      • A simple flowchart or diagram showing how tectonic shifts influence water flow and increase flood risks.
    • Ensure that the infographic is clear, visually appealing, and easy to follow.

  3. Write the Report:

    • In your report, explain:
      • The geological processes that lead to the formation of shearlines and how they are related to fault lines in Palawan.
      • How these shearlines affect the natural drainage systems, creating barriers or altering water courses, which can lead to flooding in vulnerable areas.
      • Use examples of floods in Palawan, such as those in river basins or near areas with known fault lines, and analyze how these events might have been influenced by shearlines.
      • Discuss the role of the local government and other stakeholders in mitigating flood risks in areas near fault lines. Include measures like improved drainage systems, flood forecasting, and community awareness programs.
