Special Issue Information

Dear Colleagues,

We invite you to submit your latest study findings demonstrating progress in River Delta Research. The world’s river deltas are densely populated and vital to global food security, commerce, energy production, and industrial development. Many of these deltaic regions are rapidly sinking into the sea due to a number of natural and anthropogenic factors, including disconnection of rivers with their floodplains, reduced sediment input, river engineering, coastal land subsidence, and sea level rise. Over the past decades, the world’s river deltas have experienced rapid population increase and urbanization. The anthropogenic activities have interfered with delta-forming processes and, in return, the altered deltaic forming processes are affecting humans, presenting a dynamically coupled natural–human system. As global sea level continues to rise, eroding and drowning coastal shorelines, the world’s river deltas face the continuing threat to their sustainability. However, these regions are ill-prepared to face the future challenges and satisfy the needs of their inhabitants. This Special Issue aims at bringing together the latest research on the world’s river deltas as a complex dynamic system between the natural and human environments. We encourage submissions based on field, modeling, and synthetic studies concerning deltaic geomorphology, sediment transport, hydrology, spatial organization, population dynamics, social, economics, and policy making in the vulnerable deltas. We especially encourage papers that address the world’s major river deltas and stimulate critical thinking pertinent to finding practical solutions.

The Mississippi River Delta has been continuously losing land since the 1930s due to several factors, chief of which is the reduced sediment supply. A few recent studies have estimated individual components of short-term sediment transport, i.e., bedload and suspended load, separately for some locations along the Lowermost Mississippi River (LmMR, commonly considered as the last 500-km reach of the Mississippi River before entering the Gulf of Mexico). However, the combined effects of both components on the long-term sediment supply along the river reach are still unclear. One of the major obstacles here hindering our understanding is that it is difficult and impractical to accurately measure bedloads in large alluvial rivers, such as the Mississippi. In this study, we estimated bedloads of three medium grain sizes (D50 = 0.125, 0.25 and 0.5 mm) for three locations along the uppermost 140-km reach of the LmMR: Tarbert Landing (TBL) at river kilometer (rk) 493, St Francisville (St F) at rk 419, and Baton Rouge (BTR) at rk 367.5 during 2004–2015. We also estimated suspended loads at St F during 1978–2015 and at BTR during 2004–2015 in order to discern the interactive relationship between bedloads and suspended loads. We found gradually increasing bedloads for all the three medium grain sizes from TBL (83, 41.5 and 20.75 million tons (MT), respectively) to BTR (96, 48 and 24 MT). We also found that suspended loads at TBL (reported previously) were significantly higher than those at St F and BTR during corresponding overlapping periods. Bedloads increased almost linearly with suspended loads, river discharge and river stage at the upstream locations (TBL and St F); however, such a relationship was not evident downstream at BTR. The total sediment load (bedload + suspended sediment load) was substantially higher at TBL (931 MT), while lower and nearly equal at other two downstream locations (550 MT at St F and 544 MT at BTR) during 2004–2010 (the matching period of availability of both loads). These findings indicate that the uppermost 20–25 km LmMR reach (covering TBL) has potentially entrapped substantial suspended load over the last three to four decades, while bedload transport prevails in the lower reach (covering St F and BTR). We suggest that future sediment management in the river should seek engineering solutions for moving trapped coarse sediments downstream towards the coast for the Mississippi River Delta restoration Full article
