Remote Data for Mapping and Monitoring Coastal Phenomena and Parameters: A Systematic Review

Remote Sensing, Journal Year: 2024, Volume and Issue: 16(3), P. 446 - 446

Published: Jan. 23, 2024

Since 1971, remote sensing techniques have been used to map and monitor phenomena parameters of the coastal zone. However, updated reviews only considered one phenomenon, parameter, data source, platform, or geographic region. No review has offered an overview that can be accurately mapped monitored with data. This systematic was performed achieve this purpose. A total 15,141 papers published from January 2021 June 2023 were identified. The 1475 most cited screened, 502 eligible included. Web Science Scopus databases searched using all possible combinations between two groups keywords: geographical names in areas platforms. demonstrated that, date, many (103) (39) (e.g., coastline land use cover changes, climate change, urban sprawl). Moreover, authors validated 91% retrieved parameters, 39 1158 times (88% combined together other parameters), 75% over time, 69% several compared results each available products. They obtained 48% different methods, their 17% GIS model techniques. In conclusion, addressed requirements needed more effectively analyze employing integrated approaches: they data, merged

Temporal Changes in Water and Sediment Discharges: Impacts of Climate Change and Human Activities in the Red River Basin (1958–2021) with Projections up to 2100

Water, Journal Year: 2024, Volume and Issue: 16(8), P. 1155 - 1155

Published: April 19, 2024

The present study examined temporal variations in water and sediment discharges the Red River basin from 1958 to 2021 resulting climate change anthropogenic factors, with projections extended 2100. 64-year observational period was divided into five distinct stages: 1958–1971 (Stage I: natural conditions); 1972–1988 II: onset of human activities); 1989–2010 III: post Hoa Binh dam construction); 2011–2016 IV: series new constructions); 2017–2021 V: combined effects activities change). Attribution analysis revealed that accounted for 62% 92% dramatic declines loads Stages III IV, respectively. Projection results fluvial over an approximate 150-year timeframe (1958–2100) indicate overriding impact activities. Climate based on four scenarios (−5%, +5%, +10%, +15% per year) suggest associated decreases or increases river flows. This predicts projected 21st century flow attributable will offset up eight percent human-induced load deficit.

Decadal evolution of fluvial islands and its controlling factors along the lower Yangtze River

Frontiers in Environmental Science, Journal Year: 2024, Volume and Issue: 12

Published: March 20, 2024

Fluvial islands are vital from both morphological and ecological perspectives consequently have been hotspots of morphodynamic research in large rivers around the world. This study selected 14 representative fluvial lower reaches Yangtze River explored their spatial-temporal evolution, including shape area dynamics during 1945–2016, by interpreting remote sensing images analyzing hydrological data. Results indicated that total showed a growing trend at an average rate 0.30 km 2 yr −1 72 years. The island Fenghuangzhou experienced largest change area, while Xiaohuangzhou (XHZ) had smallest area. Sediment discharge flooding were assumed to be primary natural factors controlling dynamics. Furthermore, dam construction bank reinforcement also played critical role preventing shoreline collapse, improving channel conditions, promoting stability islands. From 1976 2016, maximum erosion occurred on left XHZ, accretion was found Qingjiezhou island. Almost entire river section process right bank, which caused control structures. Besides, along appears follow processes bank. Our findings can provide important reference for sustainable utilization management

Seasonal variations of sediment load related to all large damming in the Red River system: A 64‐year analysis

Earth Surface Processes and Landforms, Journal Year: 2023, Volume and Issue: 49(1), P. 482 - 496

Abstract Variations of water discharge and sediment load in the Red River basin have received considerable attention due to its drastic reduction during past several decades. This paper presents a more specifically investigating seasonal variations from 1958 2021, both before after impoundment all large dam‐reservoirs, using daily observations Son Tay hydrological gauging station, outlet system entry delta. Sediment loads decreased progressively since early 1990s yield dams upper basin, with about 91% (from 116 × 10 6 11 t/year) over 64‐year observation period. Prior Hoa Binh dam‐reservoir 1988, processes exhibited anomalies (clockwise mode on hysteresis rating curve), which implies that is highly proportional precipitation. The loops between mean monthly suspended concentration 1988 were altered by tributary dam‐reservoirs phenomenon known as ‘temporal monsoon moving’, shifted curve clockwise counterclockwise mode. Our long‐term analysis indicates approximately 57.5% 79% sediments trapped periods 1989–2008 (after impoundment) 2009–2021 (a series new went into operation), respectively, primarily high‐discharge months (June–October). Additionally, we concluded contribution climate components (e.g., rainfall) dramatic decline was less than human impact.
