Respons kawasan tadahan air adalah disebabkan oleh pelbagai faktor. Urbanisasi adalah satu faktor yang penting dalam menyebabkan perubahan ciri-ciri hidrologi di dalam dunia. Pulau Pinang adalah salah satu Bandar yang berkembang dengan pesat di negara Malaysia. Bukti-bukti in telah ditunjukkan oleh Jabatan Pengairan dan Saliran (DID) dalam projek-projek mitigasi yang dijalankan untuk mengawal masalah banjir di Malaysia. Perbangunan bandar akan menyebabkan perubahan terhadap peratus kawasan telap di negara ini. Jadi, ini telah menjadi amat penting untuk memahami hubungan guna tanah dengan respons tadahan. Model sumber air sekarang amat popular di kalangan jurutera di dunia dalam meramal perubahan dalam proses hidrologi persekitaran. HECHMS adalah salah satu model sumber air yang dicipta oleh US Army Corps. HEC-HMS boleh mensimulasi presipitasi dan aliran sungai. Analisis perubahan peratusan guna tanah telah menunjukkan bahawa perkembangan zon komersial menyebabkan kesan perubahan yang lebih ketara daripada perkembangan kawasan pertanian. HEC-HMS telah digunakan untuk pengajian ini dan boleh mensimulasi hidrograf kawasan tadahan Sg. Pinang. ___________________________________________________________________________________ Catchment response are caused by various different factors. Urbanisation is one of the major factors causing hydrological changes to the world. Penang Island is also one of the most rapid growing city in Malaysia. This is shown by Department of Drainage and Irrigation (DID) flood mitigation projects to counter flood problems in Malaysia. Since city development will cause changes in impervious land percentage. It is necessary to understand the relationship between land use and catchment response. Precipitation runoff models are widely used in predicting changes in hydrologic processes. HEC HMS is a one of the common rainfall runoff models released by US Army Corps. The model will be able to simulate the rainfall runoff in the Sungai Pinang Catchment. Analysis of the land use changes on the catchment runoff showed that increase of commercial development shows a highest increase in peak discharge compared with agricultural expansion. The HEC HMS has been used as modeling tool in this study. HEC HMS is able to simulate the design runoff hydrograph of Sg. Pinang catchment.
