The Integrated Flood Management (IFM) Approach in Malaysia

In Malaysia, the Integrated Flood Management (IFM) approach includes a combination of structural and non-structural measures to reduce flood risk and minimize the impact of floods on people and property.

Structural measures include:

  1. Construction of dams and embankments: These structures are built to contain and control the flow of water, thereby reducing the risk of flooding.

  2. Improvement of drainage systems: This includes the construction of drainage channels and culverts, as well as the improvement of existing drainage systems to increase their capacity to handle water.

  3. River dredging: This involves removing sediment and debris from rivers to increase the capacity of the river to carry water and reduce the risk of flooding.

Non-structural measures include:

  1. Land use planning and zoning: This involves the development of land use plans that take into account the potential for flooding and the need for flood protection.

  2. Building codes: This involves the implementation of building codes that require new buildings to be constructed above the flood level.

  3. Flood warning systems: This involves the implementation of early warning systems and flood forecasting models to provide timely warning of potential floods to the public.

  4. Community-based flood management: This involves engaging local communities in flood management efforts and educating them about flood preparedness.

  5. Emergency preparedness: This includes the development of emergency evacuation plans and providing training for local communities in emergency response.

Despite these efforts, flood remains a recurrent problem in Malaysia, particularly in urban areas where the risk of flooding has increased due to rapid urbanization and land development. The factors that contribute to this include the lack of proper urban planning, poor drainage systems, and the lack of enforcement of building codes. Additionally, climate change is also exacerbating the problem, with more intense and frequent heavy rainfall events in Malaysia.

In summary, In Malaysia, the Integrated Flood Management (IFM) approach includes a combination of structural and non-structural measures to reduce flood risk and minimize the impact of floods on people and property. These measures include construction of dams and embankments, improvement of drainage systems, river dredging, land use planning and zoning, building codes, flood warning systems, community-based flood management, and emergency preparedness.

The Malaysian Meteorological Department (MMD)

The Malaysian Meteorological Department (MMD) is responsible for providing weather forecasts and warning services to the public in Malaysia. They use a combination of observational data, numerical models, and human expertise to make accurate weather predictions.

Observational data includes information from weather stations, radar, and satellites, which is used to provide real-time information about current weather conditions. The MMD uses this data to initialize the numerical models, which are used to make predictions about future weather conditions.

Numerical models are mathematical models that simulate the behavior of the atmosphere. The MMD uses several models for weather forecasting, including the Global Forecast System (GFS) and the European Centre for Medium-Range Weather Forecasts (ECMWF) models, which are two of the most widely used global models for weather forecasting. These models take into account factors such as temperature, pressure, wind, and precipitation, and use equations to simulate how these factors will change over time.

The MMD also uses regional models such as the Regional Spectral Model (RSM) and the Global Environmental Multiscale (GEM) models to make more detailed predictions for specific regions in Malaysia. These models use a higher resolution than the global models, which allows them to make more accurate predictions for a specific area.

In addition to observational data and numerical models, the MMD also relies on human expertise to make accurate weather predictions. Weather forecasters at the MMD use their own knowledge of meteorology and their experience in interpreting the data from the models to make predictions about future weather conditions. They also collaborate with international meteorological organizations such as the World Meteorological Organization (WMO) and the United Nations Framework Convention on Climate Change (UNFCCC) to improve the accuracy of their predictions.

They also use regional models such as the Regional Spectral Model (RSM) and the Global Environmental Multiscale (GEM) models to make more detailed predictions for specific regions in Malaysia. Additionally, the MMD also uses other weather forecasting tools such as radar and satellite imagery, and it also collaborates with international meteorological organizations to improve the accuracy of its predictions.

GDM2000, GDM2000 (Rev2006), GDM2000 (Rev2009), GDM2000 (Rev2016) and GDM2020

In addressing the effects of plate tectonic motion due to natural disasters such as earthquakes on the coordinates reference system and vertical datum systems for the whole country, JUPEM has successfully established a more accurate, precise and contemporary GDM2020. This newly derived geodetic datum system is fully aligned to ITRF2014, where velocities and PSD are modelled as an intrinsic component of the kinematic/ semi-kinematic concept of the CORS coordinates.

In order to facilitate the conversion of various coordinates system in Malaysia, JUPEM has produced numerous sets of datum transformation and map projection parameters to relate the different types of coordinate system.

The parameter values relating to different coordinate reference systems are derived from standard coordinate conversion formulae, Bursa-Wolf transformation formulae and multiple regression model.

The determination of a position requires the choice of a coordinate reference system. A situation now exists whereby it is common for a user acquiring data in a coordinate system that is completely different to which the data will be ultimately required.

Development of Web-Based Application for Shapefile Coordinate System Conversion for Malaysia

By Elysonia Alim
Supervised by Dr. Shahabuddin Amerudin
UTM Undergraduate Thesis Year 2018
It is difficult to process GIS vector data when they are not aligned with one another. The need for different coordinate systems rose from the fact that some coordinate systems are better fitted to describe the phenomenon happening in a specific area. However, even commercial software had been proven to have questionable accuracy in coordinate system conversions. The purpose of this study is to develop a web application capable of converting the coordinate system of a GIS data format such as a shapefile for Peninsular Malaysia. The web application named Coordinate Conversion Application (CCA v1.1) was developed using Django 2.0 with Python 3.6 and is capable of 5 coordinate transformations namely WGS84 to GDM2000 (forward and backward), WGS84 to MRSO (old) (forward only), MRSO (old) to Cassini (old) (forward and backward). Results obtained were compared with existing software such as GDTS v4.01 and ArcGIS 10.3, and analysis shows that CCA v1.1 has achieved satisfactory accuracy

ABSTRACT: It is difficult to process GIS vector data when they are not aligned with one another. The need for different coordinate systems rose from the fact that some coordinate systems are better fitted to describe the geographical phenomenon occurring in a specific area. However, even commercial software had been proven to have questionable accuracy in coordinate system conversions. The purpose of this study is to develop a web application capable of converting the coordinate system of a GIS data format such as a shapefile for Peninsular Malaysia. The web application named Coordinate Conversion Application (CCA v1.1) was developed using Django 2.0 with Python 3.6 and is capable of five-coordinate transformations namely WGS84 to GDM2000 (forward and backward), WGS84 to MRSO (old) (forward only), MRSO (old) to Cassini (old) (forward and backward).
