ABSTRACT Exploring the regional precipitation concentration index (PCI) provides profound insights into distribution patterns of rainfall within a specific area. This study utilised daily data from Sichuan Province to investigate spatiotemporal variations PCI on annual and seasonal scales, as well its potential relationships with Pacific Decadal Oscillation (PDO) El Niño‐Southern (ENSO). A modified Mann‐Kendall test was employed identify significant trends in PCI. Furthermore, this examined...
Climate change impacts on food supply and water use efficiency have become an urgent issue for the agricultural researchers governments. With climate change, resources will be a restricting factor agriculture, especially in arid semi-arid areas. This paper mainly discusses changing tendency of balance components, maize yield indices under rainfed irrigated conditions subareas Loess Plateau A2 B2 scenarios with SWAGMAN® Destiny model. The results show that evapotranspiration increase future...
Abstract The analysis of the hydrological response to meteorological drought events can lead a deeper understanding alterations in processes that be used help maintain environmental flow (e‐flow) aquatic ecosystems. In this study, we first identified an extreme event and then assessed its response. Monthly precipitation anomalies were identify drought, while Lyne–Hollick method (LH filter) was alongside baseflow recession constant (calculated using Automatic Baseflow Identification Technique...
Abstract Climate change impacts on food production and water use efficiency are becoming more important. This paper mainly discusses the climate effects indices maize yield under rainfed irrigated conditions projected by three models in Murray Darling Basin, Australia 2020, 2050 2080 A2 B2 scenarios. The prediction results show that it is similar to future precipitation temperature for same time slices. For maize, crop yield, potential actual evapotranspiration will increase 3–32, 3–12,...
ABSTRACT Water, energy, and carbon are important factors that determine crop production efficiency. This paper applies the footprint theory to calculate water, of food crops in Sichuan Province from 2011 2020, evaluates water–energy–carbon interactions closeness, employs path analysis analyse influencing coupling degree coordination degree. The results indicate (1) annual average green water (WF) exceeds combined contribution blue grey WFs, accounting for 54.69% total. Energy inputs...
In this paper, the Soil-Water-Atmosphere-Plant (SWAP) model was used in conjunction with ROSETTA, a soil hydraulic properties simulation program, to evaluate water balance for irrigated maize crop Finley, NSW, Australia. The authors moisture content data calibrate SWAP model. result shows that simulated agrees well observed excluding some very low measured value. Through analyzing components it appears there are opportunities save through better irrigation scheduling and recycling of...
Abstract In this paper, the long-term dynamics of water balance components in two different contrasting ecosystems Australia were simulated with an ecohydrological model (WAter Vegetation Energy and Solute modelling (WAVES)) over period 1950–2015. The selected are woodland savanna Daly River eucalyptus forest Tumbarumba. WAVES was first manually calibrated validated against soil content measured by cosmic-ray probe evapotranspiration eddy flux techniques. then used to simulate observed...
Climate change impacts on food production have become an interesting topic to most agricultural researchers. This paper mainly discusses the rainfed maize water use indices in subareas of Loess Plateau under A2 and B2 future climate scenarios with SWAGMAN <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">®</sup> Destiny model. The result shows that evapotranspiration will increase both while decrease for whole Plateau. Although study mentioned...
Abstract Aiming to analyse the variation of seasonal reference crop evapotranspiration (ET 0 ) and show impact meteorological factors on ET across Sichuan Province, this study mainly discussed during periods 1967–2016 in three subregions Province with Mann–Kendall test (MK), Morlet wavelet analysis path analysis. Meanwhile, future trend characteristics at different timescales were evaluated by Hurst exponents based rescaled range (R/S) method. The results indicated that over past 50 years,...
The Chapman-Maxwell method (the CM filter) with recession constant calculated from Automatic Baseflow Identification Technique (ABIT) was used to separate baseflow daily runoff at the Taonan hydrological station in Taoer River basin．Time series-based rainfall-runoff events were separated explore event response precipitation． Annual precipitation, and found show decreasing trends, abrupt decreases detected all three．Baseflow maintain continued process, a total number of 72 being identified...
