“…Dewasa ini telah berkembang pesat pemanfaatan teknik sidikjari sedimen (sediment fingerprinting) untuk mengungkap hubungan antar sumber sedimen potensial dan sedimen yang berada pada kawasan hilir [4]. Teknik sidik jari sedimen ini telah banyak di aplikasikan di negara lain untuk meneliti kontribusi sumber potensial di berbagai skala spasial dari yang berukuran demplot dalam puluhan m 2 [5], ratusan hektar [6] sub DAS baik di kebun campuran maupun di ladang. Aktivitas radionuklida Pb-210 total, Pb-210 supported dan Cs-137 pada lapisan sub-soil jauh lebih kecil dibanding pada lapisan tanah permukaan di kebun campuran dan di ladang.…”

Pengembangan perunut untuk penentuan kontribusi sumber sedimendi daerah aliran sungai Cisadane telah dilakukan. Penentuan kontribusi sumber sedimendilakukan dengan pengukuran kandungan radionuklida alam dalam tanah permukaan dandifokuskan pada daerah aliran sungai (DAS) Cisadane Hulu, yang terdiri dari sub DASCisadane Hulu dan sub DAS Cianten. Pengambilan sampel tanah permukaan (0-2 cm)dilakukan secara transek pada sumber sedimen potensial yaitu lahan olah, kebun campurandan lapisan sub soil yang ada di ke dua sub DAS. Sedimen suspensi diambil di pertemuanaliran kedua sub DAS yaitu di Dusun Tamilung. Pengambilan sedimen suspensi hanyadilakukan satu kali dengan sampling selama 10 jam. Analisis kontribusi sedimen dilakukanberdasarkan persamaan multivariate mixing model dan statistik distribusi. Kontribusi sumbersedimen dari sedimen suspensi di Dusun Tamilung adalah 0-5,2 %, 0,7-13,3 %, 0-4,2 %, 1,2-19,4 %, 28,5-55,5 % dan 25,3-45,1% masing-masing berasal dari kebun campuran di sub DASCianten, lahan olah di sub DAS Cianten, Kebun Campuran di sub DAS Cisadane Hulu, lahanolah di sub DAS Cisadane Hulu, Lapisan sub soil di sub DAS Cianten dan lapisan sub soil disub DAS Cisadane Hulu.Kata kunci : sumber sedimen, DAS Cisadane Hulu, proporsi kontribusi

“…The EPM model (Erosion Potential Method) was developed by Gavrilovic in 1988 and has been used in several studies (Ahmed et al, 2019;Amini et al, 2014;Efthimiou & Lykoudi, 2016;Kouhpeima et al, 2011;Othman et al, 2023;Pavlova-Traykova, 2022;Zahnoun et al, 2019). This method is based on three essential factors: the temperature coefficient (T), the mean annual precipitation (H), and the potential erosion parameter (Z).…”

In recent years quantitative and qualitative methods integration has become common in investigating and modeling hydric erosion. The present study focuses on using a synergistic approach of the Erosion Potential Model (EPM) and Priority Actions Program/Regional Activity Centre (PAP/RAC) in order to model the potential erosion in the Korifla Sub-watershed, Central Morocco. The combination of remotely sensed data and the EPM parameters demonstrated that the amount of soil estimated loss in the study area is between 0.001 m3/km2/y and 68.26 m3/km2/y. Furthermore, AUC (Area Under Curve) was computed to validate the EPM modeling results by implementing 162 high erosion sites, the AUC value indicates good mapping results (0.76). The PAP/RAC model shows that in the entire study area, the zones of very high and high erosion represent respectively 10.31 % and 14.53 %, whereas the equivalent of these zones by EPM represents 6.31 % and 9.52 %. The distribution of high-erosion areas correlates well with that of moderate to steep slopes, principally in forest and agricultural lands within the study area. However, the employed methods in this study successfully simulated erosion quantitatively as well as qualitatively. The findings of this study imply that hydric erosion can threaten ecological sustainability and agricultural production in several parts of the Korifla sub-watershed. Consequently, the present study results offer valuable insights for planning efficient erosion control strategies as well as redirecting soil and slope management. To sum up, the findings of this research have important implications for implementing efficient erosion control measures in north-western central Morocco, semi-arid area.

“…Erosion, sediment yield and siltation have been studied by several researchers [8] [14]- [19]. The majority have been focused on the characterization and regionalization of siltation, and they have been tried to produce practical models and monograph for each area [9] [12] [20]- [24]. Some researchers are oriented to identification and assessment of rate's erosion based on geometric, hydrological, lithological, geomorphological and climatic characteristics of the watershed [25]- [30].…”

The construction of small dams and hillside reservoirs is a common practice for dealing with erratic and unevenly distributed rainfalls in arid and semi arid areas. Moreover, these small hydraulics structures are recommended as a solution to adapt to climate change in rural areas. They are fundamental for the sustainability of the water resources. However, these dams are potential sinks for upstream sediment. Therefore, it would be useful to monitor and measure the amount of sediments in small dams because it is necessary to understand siltation and better functioning of these vital structures. This control and these measurements require the application of the bathymetry or topography surveys which is too expensive for the responsible of these small dams. In this context, this paper proposes a simple and low cost method called: Triangulation of the estimated silted level. This method is based on direct measurement of the accessible silted level in dam. This new method is compared with another method based on the initial Elevation-Capacity curve of dam, usually used when the bathymetry is not attainable. The results of both of them have been verified with those of the bathymetry and electrical tomography methods and validated the proposal method as the most approximate. Therefore, this method is recommended as a new direct and simple technique to evaluate the amount of silting in small dams and hillside reservoirs.
