dc.description | Abstrak. Menentukan jalur aliran yang dominan di dalam daerah aliran sungai dan bagaimana air mengalir berpengaruh terhadap terhadap kandungan kimia airnya merupakan hal penting dalam memahami proses limpasan. Saat ini pendekatan secara hidrometrik dan hidrokimia telah banyak dilakukan untuk memahami perbedaan persepsi antara pendekatan menggunakan model dengan konsep formal dalam mempelajari proses limpasan. Tujuan penelitian ini adalah mempelajari dinamika aliran bawah permukaan selama proses limpasan dan mempelajari keragaman ketersediaan kandungan kimia air secara spasial dan temporal. Penelitian dilakukan melalui beberapa tahapan yaitu: karakterisasi wilayah penelitian, pengamatan kedalaman batuan (bedrock), pemasangan peralatan pengamatan hidrometrik dan hidrokimia, dan pengambilan sampel air untuk analisis kimia. Hasil penelitian menunjukkan bahwa dinamika perilaku aliran bawah permukaan mempengaruhi keragaman kandungan kimia air secara spasial dan temporal. Perubahan besaran dan arah aliran bawah permukaan di wilayah lereng disebabkan adanya perubahan konsentrasi kimia air secara spasial dan temporal. Abstract. Defining the dominant flow path and how the water undergoes chemical changes is critical in understanding the process of runoff. In recent decades, hydrometric and hydro-chemical approaches have been done much to understand the differences in perception between the models and the formal concepts of runoff processes. The aims of the research were to study the subsurface flow dynamics during runoff process and the spatial and temporal variation of water chemistry. The research was conducted through several stages, i.e. characterization of the study area, observation of bedrock depth, installation of hydrometric and hydro-chemical equipment and water sampling and analysis. The results showed that the dynamics of subsurface flow behavior affected the diversity of water chemistry spatially and temporally. Changes in the amount and direction of the subsurface flow in sloping area were caused by the change in solute concentration spatially and temporally. | id-ID |
