Lower Mekong Basin (LMB) experiences a recurrent drought phenomenon. However, few studies have focused on monitoring in this region due to lack of ground observations. The newly released Climate Hazards Group Infrared Precipitation with Station data (CHIRPS) long-term record and high resolution has great potential for monitoring. Based the assessment CHIRPS capturing precipitation drought, study aims evaluate condition LMB by using satellite-based from January 1981 July 2016. Standardized...
ABSTRACT This study investigated spatial and temporal variations of extreme precipitation over Yunnan Province during 1960–2012. On the basis a dataset from 120 meteorological stations covering region, ten indices derived daily were computed analysed. Our results indicate showed spatially complex trends. Most present increasing trends in western decreasing eastern Yunnan. The western, southern central regions experienced an increase consecutive dry days (CDDs) decrease wet (CWDs). In...
Gridded precipitation products have the advantages of wide spatial coverage and high spatiotemporal resolution compared to conventional rain-gauge data, been extensively applied in hydrology-related research. As one most representative gridded products, APHRODITE performs well regions over Asia except around Tibetan Plateau. This study implemented four bias correction methods including both mean-based (LS, LOCI) distribution-based approaches (CDF, LS_CDF) for data Yarluzangbu-Brahmaputra...
Satellite-based products with high spatial and temporal resolution provide useful precipitation information for data-sparse or ungauged large-scale watersheds. In the Lower Lancang-Mekong River Basin, rainfall stations are sparse unevenly distributed, transboundary characteristic makes collection of data more difficult, which has restricted hydrological processes simulation. this study, daily from four datasets (gauge observations, inverse distance weighted (IDW) data, Tropical Rainfall...
Abstract Construction of river infrastructure, such as dams and weirs, is a global issue for ecosystem protection due to the fragmentation habitat hydrological alteration it causes. Accurate barrier databases, increasingly used determine ecologically sensitive management, are challenging generate. This especially so in large, poorly mapped basins where only large tend be recorded. The Mekong one world's most biodiverse but, like many rivers, impacts on from infrastructure documented. To...
Constrained by the sparsity of observational streamflow data, large-scale catchments face pressing challenges in prediction and flood management amid climate change. Deep learning excels simulation performance while flow lag information data-driven approaches is barely highlighted. In this study, we introduce a time-lag informed deep framework for catchments. Central to utilization between upstream downstream subbasins, enabling precise forecasting at outlet driven data. Taking...
Abstract Freshwater fishes worldwide face an array of threats from dam construction, river fragmentation, pollution, over‐exploitation and interactions with introduced species. Such impacts are especially prevalent in densely populated countries undergoing rapid development, their effects felt most strongly where regional fish diversity is high. We reviewed studies the distribution freshwater species throughout China to map a biogeographical pattern ascertain environmental factors...
Abstract Hydrological regimes of alpine rivers are highly sensitive to climate variability/change. Temperature and precipitation variability its effects on streamflow in the upstream regions Lancang–Mekong River (LMR) Nu–Salween (NSR) examined this study based long-term observational data from 16 meteorological stations 2 hydrological between 1950s 2010. This employs Mann–Kendall nonparametric test, together with trend-free prewhitening (TFPW) approach test trends Breaks For Additive Season...
Abstract Dams have fragmented rivers and threatened aquatic biodiversity globally. However, the findings regarding dam impacts on riverine macroinvertebrates vary across regions taxa. We conducted a global meta-analysis to quantify effects of dams macroinvertebrate assemblages (i.e. species richness abundance) based 3849 data points extracted from 54 publications. Responses varied among climatic zones, altitudes, sizes height), downstream distances dams, taxonomic groups. The overall effect...
<title>Abstract</title> The Mekong River, a global freshwater biodiversity hotspot, has suffered from intensive barrier construction, resulting in major challenges safeguarding its fauna. Here, we provide comprehensive evaluation of the impacts river barriers on distribution 1,032 fish species Basin. Our analysis revealed that 93% suffer habitat fragmentation, and with larger range requirements experienced higher fragmentation impacts. Sub-basins along main channel Lower had high values...
Ecological carrying capacity (ECC) is a crucial indicator for assessing sustainable development capabilities. However, mountain ecosystems possess unique complexities due to their diverse topography, high biodiversity, and fragile ecological environments. Addressing the current shortcomings in ECC assessments, this paper proposes novel hybrid evaluation framework that integrates improved footprint (EF) ecosystem service value (ESV) approaches with spatial econometric models. This allows more...
Tonle Sap Lake is the largest freshwater lake in Southeast Asia. Water development infrastructures are increasingly being constructed Lancang–Mekong River Basin, which a major concern considering its potential impact on Lake. This study aimed to investigate variations area of and discuss their possible linkage runoff alterations Lancang (Upper Mekong) by comparing at Yunjinghong hydrological station before after significant changes trends that occurred 2008. First, four commonly used water...
The Lancang-Mekong River has attracted much attention from researchers, but the cooperation on water issues in this river basin been limited, even after establishment of Mekong Commission (MRC). Cooperation resources determined as one key priority areas Mechanism, there are no details targets. In order to establish priorities under mechanism, we adopted nine categories classify objectives 87 events based 'Lancang-Mekong Water Cooperative Events Database' 1995 2015. Based occurrence...
