Abstract This study investigates changes in temporal trends and spatial patterns of precipitation Beijing over the last six decades. These are discussed context rapid urbanization growing imbalance between water supply demand Beijing. We observed significant decreases amounts from 1950 to 2012, with annual decreasing by 32% at a decadal rate 28.5 mm. In particular, decrease is more pronounced summer warm seasons when use its seasonal peak. further analyzed hourly data 43 rain gauges 1980...
The hydrological model is the primary tool for regional water resources management, allocation, and prediction. However, these models always suffer from large uncertainties multiple sources. Therefore, it necessary to conduct an uncertainty analysis before performing simulation. Sequential Uncertainty Fitting (SUFI-2), Parameter Solution (ParaSol), Generalized Likelihood Estimation (GLUE), Particle Swarm Optimization (PSO) integrated with SWAT-CUP software were used calibrate Soil Water...
In this study, 6 widely used precipitation products APHRODITE, CPC_UNI_PRCP, CN05.1, PERSIANN-CDR, Princeton Global Forcing (PGF), and TRMM 3B42 V7 (TMPA), were evaluated against gauge observations (CMA data) from 1998 to 2014, applied streamflow simulation over the Upper Yellow River basin (UYRB), using 4 hydrological models (DWBM, RCCC-WBM, GR4J, VIC). The relative membership degree (u), as comprehensive evaluation index in evaluation, was calculated by optimum fuzzy model. results showed...
Global climate change has affected vegetation cover in alpine areas. In this paper, we analyzed the correlation between Leaf Area Index (LAI) and factors of Yarlung Tsangpo River basin, identified their contributions using quantitative analysis method. The results show that study area generally exhibited an increasing trend. Grassland middle- high-altitude areas was main contributing area. Temperature is dominant climatic factor affecting change, effect which increases with rise elevation....
Abstract Variations of precipitation, temperature, and runoff in the Yellow River source region were analyzed with Mann–Kendall Spearman rank correlation tests over past 60 years. Based on seven climate scenarios from CMIP5 models under RCP2.6, RCP4.5, RCP8.5, responses hydrological process to change simulated using Variable Infiltration Capacity (VIC) model. Variation analysis results indicated that recorded temperature presented significant increasing trend. Daily minimum higher trend than...
Global reanalysis precipitation products could provide valuable meteorological information for flow forecasting in poorly gauged areas, helping to overcome a long-standing challenge the field. But not all data sources are suitable regions or perform same way hydrological modeling, so it is essential test suitability of before applying them. In this study, five widely used global high-resolution products—Asian Precipitation Highly Resolved Observational Data Integration Towards Evaluation...
Evaluating the impact of multi-source uncertainties in complex forecasting systems is essential to understanding and improving systems. Previous studies have paid little attention influence meteorological hydrological In this study, we developed a general ensemble framework based on Bayesian model averaging (BMA) for evaluating forecast Based framework, used eight numerical weather prediction products from International Grand Global Ensemble (TIGGE) dataset, four models with different...
Microbial decomposition plays a crucial role in the incorporation of straw and biochar (SSB) into soil. Lime concretion black soil (LCBS) is typical low-medium crop yield soil, it also one main types for grain production China. However, link between SSB additions bacterial communities LCBS remains unclear. This study explored effects on community composition, structure co-occurrence network patterns at different depths maize growth stages. The results showed that PH, organic matter total...
Surface water is a key natural resources and restrictive element to maintain regional ecological balance support development of social economy. River runoff the main form surface resources. Variation both river will directly influence management basin. Based on annual report series recorded 10 representative hydrometric stations major rivers in China, variations ten zones China during 1956—2018 were investigated. The results show that:① gauged shows downward trend with exception Datong...
Choosing an appropriate GCM (Global Climate Model, GCM) is of great significance for the simulation hydrological cycle over a basin under future climate scenarios. In this study, Rank Score Method (RS) with eight indicators were applied to comprehensively evaluate suitability 19 GCMs issued in Sixth Global Atmosphere and Coupled Model Intercomparison Project (CMIP6) Yellow River Basin (YRB). The results indicated that: 1) perform differently simulating precipitation YRB top six ranking from...
Conducting water resource assessment and forecasting at a basin scale requires effective accurate simulation of the hydrological process. However, intensive, complex human activities environmental changes are constraining challenging modeling development application by complicating cycle within its local contexts. Six sub-catchments Yellow River basin, second-largest river in China, situated semi-arid climate zone, have been selected for this study, considering processes under natural period...
The influence of climate change on the regional hydrological cycle has been an international scientific issue that attracted more attention in recent decades due to its huge effects drought and flood. It is essential investigate characteristics context global warming for developing flood mitigation water utilization strategies future. purpose this study carry out a comprehensive analysis changes future runoff upper Huai River basin by combining scenarios, model, frequency analysis. daily...
