ABSTRACT

This study investigates the relationship between land use types and sedimentary characteristics of fluvial bed at three rivers in Selangor, Malaysia; namely Sungai Tengi, Selangor and Langat. The diversity in population density and land development at the adjacent river banks gives associated dominant land use type as forest, agriculture and urban for Tengi, Selangor and Langat, respectively. Field sampling was conducted at consistent spatial locations for Tengi and Selangor, whereas for Langat, the bed sediment was taken at non-uniform spatial points due to limited access. Statistical analysis of the sediment bed mixture shows that forest dominated land gives finer bed sediment size at < 200 μm. Agriculture-type of land use increases the mean sediment size to medium sand, whereas bed material near to urbanized areas has coarser sediment size with > 650 μm. Correlation analysis proved that there is a relationship between types of land use with the mean sediment size. No distinctive correlation can be observed for sorting, skewness and kurtosis of the sediment with the types of land use.

 

Keywords: Correlation analysis; land use type; sedimentary characteristics; tropical rivers

 

ABSTRAK

Kajian ini melihat kepada hubungan antara guna tanah dan ciri sedimentari sedimen dasar sungai daripada tiga sungai di Selangor, Malaysia iaitu Sungai Tengi, Selangor dan Langat. Ketiga-tiga sungai ini mempunyai kepadatan penduduk dan jenis guna tanah yang berbeza dengan Tengi, Selangor dan Langat masing-masing didominasi oleh hutan, pertanian dan perbandaran. Pengumpulan sampel di tapak dilakukan pada lokasi jarak reruang yang tekal untuk Tengi dan Selangor manakala untuk Langat, sampel dasar diambil pada titik persampelan reruang yang tidak seragam disebabkan akses yang terhad. Analisis statistik bagi campuran sedimen menunjukkan kawasan didominasi guna tanah jenis hutan memberikan sedimen dasar bersaiz < 200 μm. Jenis guna tanah pertanian meningkatkan saiz purata sedimen kepada julat jenis pasir sederhana, manakala sedimen kasar dengan saiz > 650 μm dijumpai di dasar sungai dengan kawasan tebing adalah jenis perbandaran. Analisis korelasi membuktikan terdapat hubungan antara jenis guna tanah dan saiz purata sedimen. Tiada korelasi ketara dijumpai bagi pengisihan, kepencungan dan kurtosis bagi campuran sedimen diambil dengan jenis guna tanah.

 

Kata kunci: Analisis korelasi; ciri sedimen; jenis guna tanah; sungai tropika
