Dam Break Analysis in Warsamson Dam, East Papua using HEC-RAS and HEC-HMS

This project involves conducting a comprehensive dam break analysis for the Warsamson Dam using advanced hydraulic and hydrological modeling techniques. The goal of the project is to assess the potential impact of a dam break scenario and provide critical information for emergency planning and risk management.

Project Description:

The project utilizes HEC-RAS (Hydrologic Engineering Centers River Analysis System) and HEC-HMS (Hydrologic Modeling System) to simulate the hydrological and hydraulic conditions of the Warsamson Dam. Detailed models are created to analyze the flood propagation and potential impact areas downstream in the event of a dam break. The analysis provides valuable insights for developing mitigation strategies and improving dam safety.

Objectives:

  • Dam Break Simulation: Conduct comprehensive simulations using HEC-RAS and HEC-HMS to model potential dam break scenarios.
  • Risk Assessment: Assess the flood risks and potential impact areas downstream of the Warsamson Dam.
  • Emergency Planning: Provide critical information to support the development of emergency response plans and risk mitigation strategies.
  • Data Visualization: Create detailed flood maps and visualizations to communicate the analysis results effectively.

Methodology:

  • Data Collection:
    • Gather hydrological and meteorological data relevant to the Warsamson Dam area.
    • Collect existing dam design and operational data.
    • Conduct field surveys to validate and supplement the existing data.
  • Modeling: Utilize HEC-RAS and HEC-HMS software to create hydrological and hydraulic models, including dam break scenarios and flood routing.
  • Simulation: Run simulations to analyze flood propagation, identify high-risk areas, and evaluate the potential impacts of a dam break.
  • Data Processing and Visualization: Process the simulation results using GIS and CAD software to generate flood maps, risk assessments, and other visual aids to support decision-making.
