Regularly updated land cover information is a requirement for various land management application. Remote sensing scenes can provide information highly useful for real-time modeling of the earth environment. However, the spatial resolution is also a very important factor to acquire the information on satellite imagery. This paper summarizes the bas...

Habitat mapping as defined by plant communities is a common component of the planning and monitoring for conservation management. This study provided the test of two classifiers for producing the vegetation mapping in a tropical island. The selected area is Prathong Island, Phang Nga Province, Southern part of Thailand. The performance of the suppo...

Digital Elevation Model (DEM) has been widely used in hydrological model. The accuracy of hydrological model depends on the source and resolution of DEM data. This study investigated the effects of DEMs on deriving topographic and hydrological attributes. Two DEMs at four resolutions including 5m, 10m, 20m, and 30m were prepared and tested for gene...

This study aims to investigate an appropriate range of average rainfall in Phuket Province, Thailand for using in GIS applications. Kriging interpolation technique was used in the study. Rainfall data and Historical of ENSO phenomenon between 2002 and 2011 were collected from Meteorology Department, Royal Irrigation Department and NOAA (National Oc...

The paper reports the findings of an ongoing research which utilizes document analysis and the qualitative methods of in-depth interviews, focus group, participant observation, and trian-gulation. It proposes that knowledge manage-ment has a social innovation role in sustainability building and identifies the processes required to support successfu...

A self-prepared test kit for outdoor dissolved oxygen determination was prepared and evaluated against the azide modification Winkler method. Three hundred and five water samples with 3 replicates were taken from ditches at Prince of Songkla University, Pattani campus. The result showed that the 2 methods had good correlation (r = 0.999, p < 0.00)...

The effects of different concentrations of growth regulators and activated charcoal on micropropagation were studied. Seedlings of orchid, Dendrobium friedericksianum Rchb.f, cultured on Vacin and Went medium containing 1.0 mg/l α-naphthaleneacetic acid (NAA) and 1.0 mg/l kinetin (KN) significantly yielded per cultured plant, the highest average nu...

Water levels (at 5-minute intervals) and surface current velocities (at 15-minute intervals) were measured at five locations around the shore of Pattani Bay over two periods, each of 25 hours duration, and one week apart in mid-1996. Ribbon plots are used to show how the direction and speed of the surface current change with time at each location....

A combination of remote sensing techniques andin situmeasurements along a chronosequence was used to elucidate the rate of progression of the mangrove forest in the Pak Phanang Bay (SE Thailand), a large bay with an extended and rapidly accreting mud flat. The examination of black and white aerial photographs of the forest in 1966, 1974, 1989 and 1...

The effects of experimental sediment accretion on the survival and growth of Rhizophora apiculata seedlings planted on an expanding mud flat in Pak Phanang Bay (south-east Thailand) were assessed. Seedling mortality rates increased linearly (R2 = 0.87, F=75.9, P<0.0001) with increasing sediment accretion, at a rate of 3% per cm of sediment deposite...

The Coastal Resources Institute (CORIN) at Prince of Songkla University worked with local communities to understand coastal issues and opportunities of the Pak Phanang Bay in Nakhon Si Thammarat, Southern Thailand. Historically, the area has been an important agricultural field and trading town but now it is characterized by slow population growth...

Effective environmental management in Phuket is a great challenge. Phuket's rapid changes in terms of bio-physical, economic and, socio-cultural characteristics render an attempt to manage environmental impacts through traditional planning and regulation using top-down management approaches ineffective. Phuket's environmental issues are classic exa...
