Agricultural activities have been known to contribute significant impact on hydrological responses. Some of these impacts are manifested in the magnitude and frequency of flood. The watershed of the Muar river in Malaysia for instance were largely forested before and there were hardly any floods until some of the forests were converted into rubber, then into palm oil plantations. The shifting of land cover changed the natural physical characteristics of the trees and increases the frequency and magnitude of flood. This paper presents a method to investigate the relationship of leaf area index (LAI) for palm oil and rubber trees which influence hydrological responses in the watershed. The research framework is divided into three stages of work flow which are (i) historical land cover changes detection, (ii) LAI estimation and (iii) hydrological modeling. Land cover changes detection will be conducted using the satellite image classification technique, involving land cover data for 50 years. The LAI of rubber and palm oil trees will be measured utilizing the hemispherical photograph technique. Stages (i) and (ii) take into consideration the age of the trees (young, middle age and mature) because it has the influence to the structure and density of the canopy. The results of both stages (i) and (ii) will be used in stage (iii) for hydrological modeling using Soil Water Assessment Tools (SWAT). The hydrological modeling will highlight the influence of different LAI values on the hydro responses. The hydrological response results are subsequently correlated with the LAI value of rubber and palm oil trees to find the relationship between both parameters. If indeed LAI has influence in hydrological response, a series of recommendations concerning plantation practices to counter measure the impact of different LAI.
