“…Also the reduced local water area due to land reclamation along Shing Mun River is obvious and this in turn modifies the tidal range and currents. Park and Park (1998) documented that a reduction in the area of an enclosed water body due to land reclamation may increase wave amplitude and current velocities. According to Zhao et al (2006) when the tidal current is increased, the sediments will be resuspended.…”

This study provided a picture of the spatial and temporal distributions of Cr, Co, Ni Cu, Zn, As, Cd and Pb in bottom sediments of Tolo Harbour. The concentrations of the eight heavy metals differed significantly between sites due to the poor tidal flushing in Tolo Harbour. The levels of Cu, Zn, Cd and Pb were generally enriched in sediments from inner Tolo Harbour, while sediments from outer Tolo Harbour (Tolo Channel) had higher levels of Cr, Co and Ni. The redox sensitive element arsenic showed no distinct spatial pattern in Tolo Harbour. The decreasing levels of Cu, Zn, Pb and Cd in sediments with increasing distance from land demonstrated a typical diffusion pattern from land to the direction of sea. Two hot spots of Cu, Zn, Pb and Cd in sediments were located near Tai Po and Sha Tin new town, indicating that Cu, Zn, Pb and Zn were from land-derived sources. The sites with relatively high levels of Cr, Co and Ni in sediments were located in areas close to waste spoil in sea floor. The natural and anthropogenic inputs from Sha Tin and Tai Po to Tolo Harbour were mostly responsible for Cu, Zn, Cd and Pb enrichment in sediments from inner Tolo Harbour. The waste spoil in sea floor was believed to contribute to the Cr, Co and Ni in outer Tolo Harbour. The results of correlation coefficient between the eight heavy metals showed that Cu, Zn, Cd and Pb were strongly positively correlated, and Cr, Co and Ni were also significantly correlated with each other. The best explanation of strong correlation was their similar source. As, however, is not well correlated with the other seven heavy metals. The average concentrations of Cu and Zn displayed general increasing trends from 1978 to 2006 in Tolo Harbour, while the mean levels of Cr and Pb displayed a substantial decrease from 1978 to 1987, then a slight increase after 1987. No distinct temporal trends of the concentrations of Ni and As were observed from 1978 due to the inconsecutive data. On the other hand, the increasing trends of Cr, Cu, Zn, Cd and Pb were observed since 1996.

“…It also changes the dynamic geomorphology pattern of estuaries and increases the potential risks of the coastal zone. Estuarine engineering projects have been widely reported to exert instant impacts on hydrodynamics, and morphodynamics, consequently attracting intensive research attention (Park and Park 1998;Li 2010;Shin et al 2019;Guo et al 2021).…”

The estuary is highly dynamic and sensitive to external and internal forcing. We examine a chain reaction of hydrodynamic and morphodynamic responses to a series of land reclamation projects during the period 1997 to 2017 in the North Branch of the Changjiang Estuary through the Digital Elevation Model (DEM) comparison and the numerical simulation by the Finite Volume Community Ocean Model (FVCOM). The results show that tidal amplification was further strengthened by the artificially reduced channel volume in the middle and upper segments of the North Branch due to the implementation of several large-scale land-reclamation projects in the first stage (1997–2007), and the channel siltation in the middle and upper segments was in turn further promoted by the increased tidal flows with flood dominance. In the second stage (2007–2017), tidal amplification was relaxed by the channel narrowing project at the lower segment and the waterway improvement project through channel dredging works at the middle and upper segments. Contemporary erosion volume was almost balanced by the accretion volume in the North Branch because of the weakening dominance of flood over ebb flows. Spatiotemporal variation in channel accretion and erosion patterns in response to estuarine engineering projects was vividly mirrored by the change of simulated bed shear stress in that the areas with increased (decreased) bed shear stress underwent severe erosion (accretion). These findings highlight again the dynamic feature of tide-dominated estuaries and the importance of simulation tools to the estuarine management.

“…H. Dalkmann, et al (2004) [3] analyzed superimposed effectiveness and long-term cumulative effects in the Gulf reclamation. Park JW et al (1998) [4] used the hydrodynamic model, RMA-2 which was a part of TABS-MD model, applied to the open-ended Pusan harbor in order to evaluate the change of tidal currents due to the proposed land-reclamation inside the harbor. Owen RB et al (2004) [5] found that, due to population growth and urbanization, development and implementation of the large-scale reclamation project resulted in the increase in the rate of seafloor sediments.…”

Although reclamation can increase land area, it decreases natural shoreline, coastal wetland and fishery resources. It remains a contradiction between the utilization of reclamation and protection of marine resources. The effective method to judge reclamation impact on marine resources is of great importance. Based on results of three rounds expert investigation, this paper established a system to make the judgement. Two steps were taken: using Delphi method to obtain the weight of qualitative and quantitive evaluation indicators, using SPSS statistical software to get reliability test results, which show that expert opinions are in well agreement. The indicator weights were finally gived.
