Hydrological modeling of spatial and temporal variations in streamflow due to multiple climate change scenarios in northwestern Morocco

Climate Services, Journal Year: 2023, Volume and Issue: 30, P. 100388 - 100388

Published: April 1, 2023

Climate change is one of the most important factors impacting hydrological regimes. In this paper, climate impact on streamflow Loukkos basin (northwestern Morocco) evaluated using SWAT model for three future periods: near (2021–2040), mid (2041–2070), and far (2071–2100), compared to baseline 1981–2020. A set bias-corrected models was used: five regional (EURO-CORDEX), four global (CMIP6) their ensemble mean, under two representative concentration pathways respectively (RCP 4.5; RCP 8.5) (SSP2-4.5; SSP5-8.5). Furthermore, SUFI-2 algorithm in SWAT-CUP performed calibrate (1981–1997), validate (1998–2015), analyze uncertainty each dataset at ten stations. stations, statistical performance indicated a good simulation, with Nash–Sutcliffe efficiency (NSE) greater than 0.77 percent bias (PBIAS) within ±10% monthly basis. Overall, 82% that could decline streamflow. The largest decrease would be 2071–2100 8.5/SSP5-8.5. Our findings help planners policymakers developing reasonable water management policies adaptation measures.

Projection of climate change impacts on extreme temperature and precipitation in Central Poland

Scientific Reports, Journal Year: 2023, Volume and Issue: 13(1)

Published: Oct. 31, 2023

Climate change is exacerbating the risk of occurrence extreme weather. This study has projected in mean and climate conditions Central Poland during near-future (2026-2050), mid-term (2051-2075), far-future (2076-2100) periods under two climate-change scenarios six General Circulation Models (GCMs) from Coupled Model Intercomparison Project Phase 6 (CMIP6). The results showed that, compared to historical reference period (1990-2014), will experience an increase temperature precipitation by end twenty-first century. It expected that annual totals 1-4.8 °C 2-7.5%, respectively. Furthermore, it average number hot, very hot days extremely (Tmax > 25 °C, 30 35 °C), tropical nights (Tmin 20 high daily (> 10 mm, mm mm) also increase, while slight frost < 0 severe Tmax - °C) decline on Therefore, essential for policymakers take some appropriate measurements strategies advance strengthen resilience events.

Assessing Future Precipitation Patterns, Extremes and Variability in Major Nile Basin Cities: An Ensemble Approach with CORDEX CORE Regional Climate Models

Climate, Journal Year: 2024, Volume and Issue: 12(1), P. 9 - 9

Published: Jan. 14, 2024

Understanding long-term variations in precipitation is crucial for identifying the effects of climate change and addressing hydrological water management issues. This study examined trends mean four extreme indices, which are max 1-day amount, 5-day consecutive wet days, dry historical observations (1971–2000) two future periods (2041–2060/2081–2100) under RCP2.6 RCP8.5 emission scenarios over Nile River Basin (NRB) at 11 major stations. Firstly, empirical quantile mapping procedure significantly improved performance all RCMs, particularly those with lower performance, decreasing inter-model variability enhanced seasonal variability. The Mann–Kendall test was used to detect indices. reveals that changes vary across stations, scenarios, time periods. Addis Ababa Kigali anticipated a significant increase ranging between 8–15% 13–27%, respectively, while Cairo Kinshasa exhibited decrease around 90% 38%, respectively. Wet (dry) spells were expected (increase) most parts NRB, especially during second period (2081–2100). Thereby, (decrease) (wet) could have direct impact on resource availability NRB. also highlights increased greenhouse gas emissions greater patterns. study’s findings might be useful decision makers as they create NRB-wide mitigation adaptation strategies deal change.
