Assessment of River Plan Change Using Rs and Gis Technique

Abstract

Rivers is one of the complex natural systems. Classification of the river plan change is very important to know the river problems in early stage, where the classification database can help to understand the behavior of the river in each part. This article discusses about the classification of river plan change at the mainstream of Pahang River, Malaysia. Based on Geographical Information System (GIS) and Remote Sensing (RS) database, analysis of Types Of Lateral Activity (TYLAT) method and Modes of Meander Movement (MOME) method have been used to identify the evolution of the river plan change. The study results indicated, methods of TYLAT are more suitable to use for examining the evolution of river plan change for large and width rivers. While, method of analysis MOME index is more suitable for smaller types of rivers as the upper and middle reaches of the river. From this result, this study can be produced the basic information or database to understanding the characteristics or behavior parts in parts of the main Pahang River. This result also is very important to local authorities to know the early river problems in this area.

Assessment of Hydrological Inspection using Development Low-Cost Boat Application in University Sultan Zainal Abidin (UniSZA) Lake, Terengganu, Malaysia

“…There are some problems occur but had been solved at the end of the fabrication process [24]- [26]. The expected result for this study is hydro survey boat can give the best performance during the process of collecting data (environmental impact assessment) [27]- [30]. Moreover, the hydro survey boat can give a huge impact in terms of safety to the user compared to the manual boat.…”

Influence of Catalyst Preparation Conditions on Coconut Shell-derived Solid Acid Catalyst Performance for Transesterification

“…In addition, biodiesel produced less emission, non-toxic and biodegradable [2]. The application of biodiesel could contribute to reducing the impact of global warming [3]- [7].…”

Assessment of Natural Groundwater Recharge in Terengganu, Malaysia

“…Recharge estimation has no reliable techniques that will lead to the accurate results, but it can be based on a wide variety of models which are designed to represent the actual physical processes. The most common methods use for estimation of natural groundwater recharge include groundwater balance method, soil water balance method, zero flux plane method, onedimensional soil water flow model, and inverse modeling techniques and isotopes and solute profile techniques [1]- [4].…”
