However, a major challenge in hydrological modelling is accurately integrating both LU&LC and climate projections to address uncertainties in future water availability. This study evaluates how LU&LC and climate change together affect hydrology of the basin for future climate change scenarios. The future LU&LCs are projected using the Dyna-CLUE model for three user-defined scenarios such as past trend, drastic change in built-up and barren land, and restricted agricultural land. CMIP6 climate data was used under three scenarios SSP245, SSP370 and SSP585 which was then ensemble using the Reliable Ensemble Averaging (REA) method at each grid for both precipitation and temperature. The SUFI2 algorithm in SWAT-CUP tool is used to calibrate and validate the SWAT model for the years 1983-2017. The average monthly streamflow is projected for both LU&LC and SSP climate change scenarios during the baseline period (1983-2014), as well as for three future periods.: the near-future (2025-2040), mid-future (2041-2070) and far-future (2071-2100). Streamflow, total aquifer recharge and evapotranspiration increase in the three selected future periods when compared to baseline period in all three SSP scenarios. When combining both LU&LC and climate change scenarios, the LU&LC scenario 2 exhibits more change in streamflow, surface runoff, total aquifer recharge compared to the climate change scenario alone. In the near-future the streamflow was increased the most in the months of July by 56.13 % for climate change scenario SSP370 with LU&LC scenario 2 in the near-future period compared to the baseline period. Similarly, in the mid-future, the maximum increase was observed in June by 67.52 % for the combined impact of SSP585 and LU&LC scenario 2. In the far-future period, the maximum increase is in the month of July by 133.4 % for the combined impact of SSP585 and LU&LC2. Increasing precipitation under future climate scenarios is expected to significantly enhance streamflows, particularly from August to November, with October consistently experiencing peak flows, highlighting the need for improved flood management strategies in response to intensifying hydrological extremes. This study addresses key methodological challenges by integrating dynamic LU&LC projections, ensemble climate model data processing, and advanced calibration techniques to improve hydrological predictions. In light of projected LU&LC under climate change scenarios, the findings can be used to plan and develop short-term and long-term integrated water management strategies for the basin. Other basins in comparable physiographic regions all over the globe can use this methodology.</p>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"380 ","pages":"125096"},"PeriodicalIF":8.0,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143741713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present work aims to develop an improved sulfur-iodine cycle, here called the five-step sulfur-iodine cycle, that replaces direct sulfur oxidation with a reaction between metallic oxygen carrier (OC) and elemental S to produce hydrogen. This new cycle does not only produce more H₂, but also produces extra H₂SO₄. The process is followed by a hydrolysis reaction to regenerate OC and produce additional hydrogen. Hydrogen sulfide from the flue gas is considered the major feedstock for the developed system. The stoichiometry of the cycle is also studied to ensure that all the reactants follow the cyclic pathways. The cycle is then modeled in the Aspen Plus process simulation software under steady-state conditions, and a comprehensive thermodynamic analysis of the entire system is conducted using energy and exergy methods, evaluating energy and exergy efficiencies, as well as the exergy destruction rates of major components. Furthermore, several parameters are thoroughly examined to better investigate the system peformance. The proposed cycle demonstrates a significant improvement in hydrogen yield, and produces 4 moles of H₂ per mole of H₂S. This represents a 100 % increase in hydrogen production efficiency compared to the conventional S-I cycle, which either produces 1 mole of H₂ or 2 moles of H₂ per mole of H₂S. The hydrolysis and Claus reactors exhibit the highest exergy destruction rates accounting for 33.19 % and 16.69 % of the total exergy destruction rates, respectively. The energy and exergy efficiencies of the CBD section are found to be 72.89 % and 48.54 % respectively.

Wind energy is an attractive option due to its low cost and sustainability, but it poses significant risks to birds and bats through collisions and barotrauma with wind turbines. We examined the main ecological traits linked to wind turbine mortality in 214 bird and 19 bat species in peninsular Spain. We assessed the vulnerability of bird and bat assemblages to help understand the potential impact of wind energy development on the most vulnerable assemblages. Our findings indicate that bird and bat casualties were driven by morphological and ecological traits. For birds, scavenger species, those with partial migratory patterns, and aerial lifestyles were most affected by turbine collisions. We also found that vulnerability was positively correlated with observed mortality rates at the province level, but the effect was weaker for birds. Sensitive areas for birds and bats are located in southern, south-eastern, and central Spain, with birds showing additional vulnerability in western and northern regions, while future wind energy development affects bats more in eastern Spain. Our research highlights the importance of mitigating impacts on vulnerable bird and bat species, as well as abundant species.
