IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

ABSTRACT
Poor land use management especially on hilly areas, inadequate drainage system coincide with La-Niña phenomenon
frequently leads to flood events, and it has severe impacts on environment and socio-economy for the affected areas. This
study analysed flood occurence in Kota Marudu, Sabah based on rainfall data and flood records in Kota Marudu between
2000 and 2012 in relation to Southern Oscillation Index (SOI). Small variability (p<0.005) from all stations with the higher
average annual rainfall (AAR) for Ongkilan is the highest which demonstrates similar pattern during the study period.
Flood occurrence was recorded twice per year in 2000, 2006 and 2009. While the longest day of flood recorded on 1st to
15th Jan 2007. Significant relationship was observed between SOI with flood occurrence in Kota Marudu from 2000 to
2010 (p<0.0001). Flood mitigation action taken by the authorities efficiently prevent the flood occurrence in the strong La-
Niña year in 2008 (AAR>3000mm of all stations). However, there is strong influence of land use, due to urbanization and
development, and topography features where more frequent flood events were recorded in Tandek compared to Kota
Marudu (p<0.0001). The flood probability could be projected in the flood prone area such as Kota Marudu for more
efficient mitigation plan and controlling action.
