“…After entering the plain it follows a meandering track in a southwest direction, c. 8 m deep incised into the old fan surface (J1). Across the two younger fans (J2 and J3) it continues via nearly straight river sections over an elevated alluvial ridge until it ends up in a distributary system of bifurcating canals, all debouching into the Shadegan Marshes (Walstra et al , ; Heyvaert et al , ). The Zohreh is the only other river (in addition to the Karun) that reaches the Persian Gulf and has developed a small delta (Gharibrezaa et al , ). It enters the Lower Khuzestan Plain north of the Rag‐e Safid Anticline and follows a meandering course until its mouth (Z1).…”

This study aims to understand (mainly qualitatively) the long‐term role of human impact on avulsion processes and the development of fluvial (mega‐) fans in semi‐arid environments. In this paper we refer to human impact as the direct influences of actions on the river's hydraulics (i.e. flow regulation, flow diversion and channel engineering). In five case‐studies drawn from the Khuzestan plains in southwest Iran we have analysed the setup and triggering conditions of specific avulsions that occurred in the past (timescale of millennia) and identified the role of human interference in their causation. Our analysis is based on the integration of historical, archaeological, geomorphological and geological data. Through this study we demonstrate that avulsions in the Khuzestan plains are the result of long‐term and complex interplay between multiple human‐induced and natural causes. In similar ways human‐induced actions may play important roles during different phases of avulsion development. The ‘success‘ of an avulsion in the post‐triggering phase may be defined by human‐induced setup causes as well as morphodynamic processes. We suggest that present‐day flood events may be partly inherited from long‐term human alterations of the natural processes. These finding could have implications for any fluvial system (e.g. distributive fluvial systems, deltas) where avulsion plays a major role in their development and research tends to emphasize on natural mechanisms.

“…1.3). Sedimentation decreases the storage capacity of reservoirs worldwide (Gharibreza et al 2014;Palmeiri et al 2001;Nagle et al 1999). Based on these outcomes he stated that yearly suspended sediment yields from river basins in many unindustrialized states could be likely to twofold within almost 20 years.…”

“…Deforestation in Iran has been more rapid in the past 50 years than at any time in Iran's history. The important influences of soil erosion are manifest in areas which don't have erosion but suffer from its consequences by sediment deposition in watercourses and reservoirs, water quality and flow rate decreasing (Gharibreza et al 2014). Moreover, sedimentation in water channels clogs the water ways; it may also transfer pollutants into farm lands and dams, which are used for irrigation and drinking purposes (Sarmadian et al 2010).…”

Environmental impact of the Midia Port - Black Sea (Romania), on the coastal sediment quality

Abstract:The aim of the study was to evaluate the impact of potential pollution sources, mainly from the upstream anthropogenic sources and port-related activities. The investigated area covered a wide range of anthropogenic impacts (e.g., industrial wastes, storm water runo , accidental oil spills, intentional discharges and shipping activities). The quality of water and sediments was assessed using standard methods, as physical-chemical parameters, chemistry and biology (microbiology, ecotoxicology) aiming to gure the level of pollution and the e ect of portrelated activities. Seawater quality results agreed generally with environmental standards. Though, in some samples the concentrations of sulphates (mg/l) and heavy metals (µg/l), as B, As and Se exceeded the recommended limits, without posing a serious environmental concern. Most of the surface sediment samples contain critical levels of hydrocarbons (C>12), (mg/kg), polycyclic aromatic hydrocarbons (ng/g) and polychlorobiphenyls (ng/g). For some heavy metals (mg/kg), exchangeable concentrations were found to be very close or above the regulations. The signicance of this study is incontestable taking into account the lack of previous relevant historical data of this area. In this sense, it was possible to indicate, in general, good environmental conditions, despite the industrial and concentrated local port-related activities in the investigated area.
