Spatial Analysis of the River Line and Land Cover Changes in the Kampar River Estuary: The Influence of the Bono Tidal Bore Phenomenon

Abstract

Abstract. The Kampar River estuary is well known for a tidal-bore phenomenon called system of Kampar River. Scoured materials, resulting from the hydraulic jump of the tidal bore, are carried into the middle of the river. These materials are then deposited when the velocity of the river decreases as a result of the collision of the tidal current sedimentation with respect to the river line and perform land-cover change analysis for the area around the Kampar River estuary for the years of 1990, 2007, 2010 and 2016. which uses an overlay technique to yield alternate information on the river line and land-cover changes in the form of time-series data. The largest erosion occurred during plantations (11.57 ha/year), building/settlement (48.11 ha/year) and scrubland (30.88 ha/year). The other types of land cover, such as bare land and sediment deposition, varied every single year. The changes to the river line are caused by land-cover changes, and the Bono waves that lead to erosion and sedimentation that is not stable in the middle of the river and downstream.Keywords: spatial analysis, land cover, Bono, Landsat imagery, Kampar River estuary. Kampar untuk periode 1990Kampar untuk periode , 2007Kampar untuk periode , 2010Kampar untuk periode , dan 2016 Abstrak. Muara sungai Kampar terkenal dengan fenomena Tidal Bore yang disebut terhadap dinamika sistem muara di sungai Kampar. Material sedimen yang teraduk karena lompatan hidrolik dari tidal bore terbawa hingga ke bagian tengah sungai. Material tersebut terendapkan ketika kecepatan arus menurun sebagai akibat dari pertemuan dua arus yaitu arus dari laut dan aliran sungai. Tujuan dari penelitian ini adalah untuk mengetahui wilayah erosi dan sedimentasi dengan menggunakan pendekatan analisis perubahan garis sungai dan tutupan lahan disekitar muara sungai

Policy Directives for Sustainable Settlement Development at Flood Hazard Zone in Limapuluh Kota District West Sumatera Province, Indonesia

“…According to Sadyohutomo (2008); Mutaáli (2012); Umar and Dewata (2017), that high population growth in a region will create conflicts between land use. Kaur et al, (2004), Personal et al, (2007, Putra et al, (2017), added high population growth will lead to a shift in the ecological function of space, waking space is more dominant and urges the natural space to change function. Changes in the ecological function of the space will lead to a reduction in the ability of the land to absorb water during the rainy season.…”

Karst of Gunung Sewu Land Use and Land Covers Dynamics: Spatio-Temporal Analysis

“…We used two types of data and combined them in order to make a comprehensive analysis. The LULC data were derived from Landsat 8 satellite imagery, which is commonly employed for LULC modelling (Afrin et al, 2019;Putra et al, 2017;Raziq et al, 2016;Setyowati, 2021;Wijaya, 2015), accessed through a GEE dataset. To capture the dynamics, we used the 2013 and 2021 data acquisitions.…”

Sediment Movements in Estuary of Siak River, Riau Basin, Indonesia

“…is phenomenon shows that the northward movement is more dominant, and hence it can be estimated that TSS will spread predominantly northward in the Bengkalis Strait, as a result of the residual circulation (Putri and Pohlmann, 2009). According to Edison et al (2009), the high concentration of sediment transport in the coast is caused by the high suspended particles transported by the waves. is is in line with the results of Mubarak at al (2017) study which explains that the distribution of sediment in the waters is strongly in uenced by the wave and the current movements.…”
