“…Aerial photographs provide useful historical data that can be used to explore geomorphic change (Trimble and Cooke, 1991), including the dynamics of fluvial landforms. In recent decades, researchers exploited GIS (geographic information systems) to enhance the utility of aerial photographic data (e.g., Gurnell et al, 1994Gurnell et al, , 1998Graf, 2000;Winterbottom, 2000).…”

“…Pemanfaatan informasi historis dalam bentuk peta, foto udara, citra satelit, dan survey dapat memberikan informasi kondisi masa lalu untuk penelitian geografi khususnya di bidang geomorfologi (Trimble and Cooke, 1991). Penelitian perubahan garis sungai juga telah banyak dilakukan (seperti Gurnell, et al, 1994;Gurnell, 1997;Li, et al 2007;Ollero, 2010;Brookes, 1994dan Sarma, et al 2007).…”

Sungai senantiasa mengalami perubahan dari segi ruang dan waktu, khususnya Sungai Musi di Kota Palembang yang memiliki peran strategis sebagai urban rivers mulai dari pemerintahan kolonial hingga saat ini. Salah satunya adalah perubahan sempadan sungai akibat erosi dan sedimentasi. Tujuan dari penelitian ini adalah untuk mengidentifikasi seberapa besar perubahan sempadan Sungai Musi dalam kurun waktu 90 tahun terakhir dan pemanfaatan lahan hasil sedimentasi sungai saat ini. Fokus penelitian ini adalah Sempadan Sungai Musi sepanjang 10,85 km dari panjang total 27,47 km Sungai Musi yang membelah Kota Palembang.Metode penelitian yang diterapkan adalah deskriptif kualitatif dengan penerapan teknologi Sistem Informasi Geografis (SIG). Data yang diolah berupa Peta Sejarah Kota Palembang Tahun 1922 dan Citra satelit Quickbird Tahun 2012 yang dianalisis dengan teknik overlay berupa symmetrical difference dan geoprocessing. Hasil dari penelitian ini menunjukkan bahwa tingkat sedimentasi di sempadan Sungai Musi sangat besar dibandingkan tingkat erosinya yaitu sebesar 93%. Kecamatan Gandus dan Kecamatan Seberang Ulu I memiliki wilayah tersedimentasi yang paling besar yaitu 31% dan 29% yang banyak dipengaruhi oleh aktifitas manusia. Sebaliknya, wilayah yang tererosi cukup besar adalah Kecamatan Kertapati sebesar 65% akibat pengaruh arus dari Sungai Kramasan. Hasil sedimentasi di sempadan Sungai Musi banyak dimanfaatkan menjadi lahan permukiman (47,4%), waduk/danau (22,3%), rawa (10,7%) dan 7 penggunaan lahan yang lain dengan kisaran 0,2-6,6%. Hasil akhir penelitian ini berupa peta perubahan sempadan sungai musi di kota Palembang. Hasil temuan penelitian ini, dapat dijadikan acuan penelitian selanjutnya dalam mengembangkan produk pembelajaran sebagai upaya mengenalkan perubahan Sungai Musi di Kota Palembang baik di sekolah maupun pada mata kuliah Sistem Informasi Geografis, Geologi, Geomorfologi, dan Hidrologi.

“…Historical hydromorphological adjustments should be evaluated on an accurate spatial scale and a high temporal resolution to identify past evolutionary processes and causal relationships (Bogen et al, 1992;Horowitz et al, 1999). 30 Interdisciplinary and retrospective studies, however, rarely combine different data sources to obtain a comprehensive view of functional changes (Bravard and Bethemont, 1989;Gurnell et al, 2003;James et al, 2009;Lawler, 1993;Lespez et al, 2015;Rinaldi et al, 2013;Trimble and Cooke, 1991). Furthermore, historical studies rarely consider sediment dating and pollution (Bogen et al, 1992;Garban et al, 1996;Horowitz et al, 1999;Woitke et al, 2003).…”

Abstract. While the history of a fluvial hydrosystem can provide essential knowledge on present functioning, historical context remains rarely considered in river restoration. Here we show the relevance of an interdisciplinary study for improving 15 restoration within the framework of a European LIFE+ project on the French side of the Upper-Rhine (Rohrschollen Island).Planimetric evolution combined with historical high flow data enabled to reconstruct pre-disturbance hydromorphological functioning and major changes that occurred on the reach. A deposition frequency assessment combining vertical evolution of the Rhine thalweg, chronology of deposits in the floodplain and a hydrological model revealed that the period of vertical incision in the main channel corresponded to high rates of narrowing and lateral channel filling. The analysis of filling 20 processes by Passega diagram and IRLS dating highlight that periods of engineering works were closely related to fine sediment deposition, which present also concomitant heavy metal accumulation. In fact, current fluvial forms, processes and sediment chemistry around the Rohrschollen Island directly reflect the disturbances that occurred during past correction works, and up to today. Our results underscore the advantage of combining functional restoration with detailed knowledge of pasttrajectory to: (i) understand the functioning of the hydrosystem prior anthropogenic disturbances, (ii) characterize the human-25 driven morphodynamic adjustments during the two last centuries, (iii) characterize physio-chemical sediment properties to trace anthropogenic activities and evaluate the potential impact of the restoration on pollutant remobilization, (iv) deduce postrestoration evolution and (v) evaluate efficiency and sustainability of the restoration effects. We anticipate our approach to expand the toolbox of decision-makers and help orientating functional restoration actions in the future.
