“…In recent times, the impacts of land use/cover change (LULCC) on hydrology have gained tremendous concern on the part of researchers [22][23][24][25], with little consideration accorded sediment fluxes [5,10]. This in part is explained by the extreme difficulties in measuring sediment fluxes and hence the unavailability of required sediment data for further studies [26,27]. The spatial extent of soil erosion causing sediment fluxes presents many difficulties for its continuous monitoring amidst scarce human resources, site remoteness and logistical constraints [28].…”

Abstract:Intensified human activities over the past decades have culminated in the prevalence of dire environmental consequences of sediment yield resulting mainly from land use changes. Understanding the role that land use changes play in the dynamics of sediment yield would greatly enhance decision-making processes related to land use and water resources management. In this study, we investigated the impacts of land use and cover changes on sediment yield dynamics through an integrated approach of hydrologic modelling and principal component analysis (PCA). A three-phase land use scenario (2000, 2007 and 2013) employing the "fix-changing" method was used to simulate the sediment yield of the Olifants Basin. Contributions in the changes in individual land uses to sediment yield were assessed using the component and pattern matrixes of PCA. Our results indicate that sediment yield dynamics in the study area is significantly attributed to the changes in agriculture, urban and forested lands. Changes in agriculture and urban lands were directly proportional to sediment yield dynamics of the Olifants Basin. On the contrary, forested areas had a negative relationship with sediment yield indicating less sediment yield from these areas. The output of this research work provides a simplistic approach of evaluating the impacts of land use changes on sediment yield. The tools and methods used are relevant for policy directions on land and water resources planning and management.

“…The standard deviation of trended and detrended series shown in Figure 5, indeed, is very similar (0.55 g/m 3 for the first and 0.49 g/m 3 for the latter). Such a trend can be associated to a reduction in the precipitation rate during the autumn-winter season in the Mediterranean basin as observed for the 1951-2010 period for the Bradano river catchment [46]. Despite this general decreasing tendency, the occurrence of moderate-to-heavy rainfalls has increased in frequency and intensity over the last decade [34], generating for example the extreme December 2013 event.…”

Abstract:Monitoring river plume dynamics and variations in complex coastal areas can provide useful information to prevent marine environmental damage. In this work, the Robust Satellite Techniques (RST) approach has been implemented and tested on historical series of Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) data to monitor, for the first time, Suspended Particulate Matter (SPM) anomalies associated to river plumes. To this aim, MODIS-Aqua Level 1A data were processed using an atmospheric correction adequate for coastal waters, and SPM daily maps were generated applying an algorithm adapted from literature. The RST approach was then applied to these maps to assess the anomalous presence of SPM. The study area involves the Basilicata region coastal waters (Ionian Sea, South of Italy). A long-time analysis (2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015) conducted for the month of December allows us to find that the maximum SPM concentration value was registered in December 2013, when an extreme hydrological event occurred. A short-time analysis was then carried out applying RST to monitor the dynamics of anomalous SPM concentrations. Finally, the most exposed areas, in terms of SPM concentration, were identified. The results obtained in this work showed the RST high potential when used in combination with standard SPM daily maps to better characterize and monitor coastal waters.

Abstract. Many ports in Indonesia who have problems with limited dock land, yard and warehouse and equipment. There is a dock that has good equipment, but Yard Occupancy and Berth Occupancy ratio are high ratio. Boom Baru port in the city of Palembang, in Indonesia, has good hinterland and the number of ship visits is quite high, but can not increase productivity or capacity of the port due to the rapid sedimentation of the port basin and land constraints to accumulation of goods. In this study, the method used to determine the condition of the real problems of sedimentation conducted through analysis of sediment concentration and sediment discharge a total of either scenario sediment from upstream (river) as well as the source of sediments estuary (port basin) [1] . By knowing the pattern of flow and sediment caracteristic process of sedimentation and erosion in the estuary, can be calculated by the method of Yang [2] .The calculation and analysis show that the sedimentation on the Musi river is high enough where the sludge reaches 40 cm/month. While the volume of sedimentation in the pools of Boom Baru port calculated using the Yang method, amounting to 13,081.42 m3/year.
