Abstract Estuaries have great ecological and economic value sustain both population growth. Global‐scale analyses suggest that human activities drive estuarine area change but these projections neglect direct human‐estuary interactions socio‐economic feedbacks. Here, we quantified changes of 2,396 estuaries in response to recent impacts (e.g., land reclamation, dam construction) development between 1984 2019, find shrank by 5,372 km 2 whereas upland submergence created 5,015 elsewhere....
Abstract Estuarine dams are constructed for securing freshwater resources, flood control, and improving upstream navigability. However, their impact on estuarine currents, stratification, sediment fluxes is not well understood. To develop a general understanding, an idealized modeling study was carried out using the COAWST system. Idealized geometry based 10 estuaries with located near mouth. Tide river forcing were varied to produce strongly stratified, partially mixed, periodically...
The rapid advance of remote sensing technology during the last few decades provides a new opportunity for measuring detectable estuarine spatial change. Although surface area and convergence are important hydraulic parameters often used to predict long-term evolution, majority automated analyses channel plan view dynamics have been specifically written riverine systems limited applicability most estuaries in world. This study presents MorphEst, MATLAB-based collection analysis tools that...
The Nakdong Estuary of Korea is a dramatic example an urban estuary that has been heavily developed with the installation two estuarine dams and approximately 17 km 2 tidal flat reclamation. This study aims to understand relative contribution different physical alterations by implementing four model simulations COAWST modeling system: (1) present condition, (2) pre-estuarine dam construction, (3) pre-tidal reclamation, (4) both construction pre-reclamation. In Cases 4, grid was modified...
Tidal salt marshes offer crucial ecosystem services in the form of carbon sequestration, fisheries, property and recreational values, protection from storm surges, are therefore considered one most valuable fragile ecosystems worldwide, where sea-level rise direct human modifications resulted loss vast regions today’s marshland. The extent relies heavily on interplay between upland migration edge erosion. We measured changes marsh size based historical topographic sheets 1850s 2019 satellite...
Coastal embayments provide vital benefits to both nature and humans alike in the form of ecosystem services, access waterways, general aesthetic appeal. These coastal interfaces are therefore often subject human development modifications, with estuarine especially likely have been anthropogenically altered. Frequent alterations include damming eliminate tidal influx, backfilling create new land, for sake economic gain, which may cause profound damage local habitats. By providing a record...
