Abstract Although there have been extensive studies on the hydrological and erosional impacts of logging, relatively little is known about the impacts of conversion into agricultural plantation (namely rubber and oil palm). Furthermore, studies on morphological impacts, sediment-bound chemistry and forensic attribution of deposited sediment to their respective sources are scarcer. This chapter introduces the potential for using the multi-proxy sediment fingerprinting technique in this context. Featuring pilot projects in two major flood-prone river systems in Malaysia, the studies explore application of geochemistry-based sediment source ascription. The geochemical signatures of sediment mixtures on floodplains were compared to sediments from upstream source tributaries. The tributaries were hypothesised to have different geochemical signatures in response to dominant land management. The first case study took place in the Segama River system (4,023 km2) of Sabah, Malaysian Borneo where a mixture of primary forest, logged-forests and oil palm plantations were predominant. The second case study was in the Kelantan River Basin (13,100 km2) with two major tributaries (Galas River and Lebir River) where logged-forests and rubber and oil palm plantations are dominant land-uses. Both case studies demonstrated the applicability of this method in ascribing floodplain deposited sediment to their respective upstream sources. Preliminary results showed that trace elements associated with fertilisers (e.g. copper and vanadium) contribute to agricultural catchment signatures. Alkaline and alkaline-earth elements were linked to recently established oil palm plantations due to soil turnover. Mixing model outputs showed that contributions from smaller, more severely disturbed catchment are higher than those from larger but milder disturbed catchments. This method capitalises on flood events to counter its adverse impacts by identifying high-priority sediment source areas for efficient and effective management.

Abstract Flood Emergency Response Plan (ERP) is a plan that guides responsibilities for proper operation of Sultan Abu Bakar (SAB) dam in response to emergency incidents affecting the dam by high water storage capacity. Based on this study, four major responsibilities are needed for SAB dam owing to protect any probable risk for downstream which can be Incident Commander, Deputy Incident Commander, On-scene Commander and Civil Engineer. Having organisation charts based on ERP exercise can be helpful for decreasing the probable risks in any projects such as Abu Bakar Dam and it is a way to identify and suspected and actual dam safety emergencies. A dam safety emergency is an event, which could potentially lead to dam break and need to be taken care of a massive plan. To mitigate the hydro hazard due to dam break, UNITEN has developed a new application software known as INSPiRE (Interactive Dam Safety Decision Support System). INSPiRE, as an intelligent dam safety software, is developed to address emergencies, which demand fast, decision making and effective multi-agency collaboration due to SAB dam break event. INSPiRE will contribute towards the sustainability of SAB dam’s owner as corporate reputations can be ruined through dam structural failures that can affect the economy of the nation and enhance the quality of life of the people.
