This research delves into the crucial role of groundwater in underpinning ecosystems and human resilience amidst drastic unpredictable climate change, particularly as water resources face increasing sustainability concerns due to population surges change. Utilizing a combined approach SWAT-MODFLOW models, we estimate streamflow discharge recharge Choushui River Alluvial Fan, Taiwan. These models allow evaluation distribution proportion areas well accuracy potential influence future change scenarios on recharge. The findings show strong correlation between simulation actual observations, evidenced by Nash–Sutcliffe model efficiency coefficients (NSE) 0.920 0.846 for calibration validation River, 0.549 0.548 Pei-Kang respectively. demonstrates reliable representation watershed response, supported robust statistical performance. analysis reveals variable impacts recharge, dependent chosen scenario period. Some indicate that maximum observed increase is 66.36% under RCP2.6 long-term period (2061–2080), while minimum 29.67% RCP4.5 initial time frame; however, all demonstrate decrease ranging from 23.05% 41.92% across different RCPs impact over time, suggesting study provides indispensable insights spatial hotspots top fan range rates underscoring importance continuous thorough multiple scenarios. Moreover, establish primary framework using top-ranked MIROC5 projection general circulation (GCMs) delineate an essential premise facilitates advanced exploration alternative augmentations, bolstering comprehensive investigation It proposed these serve guidepost sustainable resource management policy-making escalating demand.

Assessment of climate change impacts on hydrological processes in the Usangu catchment of Tanzania under CMIP6 scenarios

Journal of Water and Climate Change, Год журнала: 2023, Номер 14(11), С. 4162 - 4182

Abstract Climate change is anticipated to have long-term effects on hydrological processes and patterns, leading water stress in agroecological catchments. escalates scarcity the Usangu catchment, as evidenced by drying up of rivers during dry season. Therefore, this study was undertaken assess climate impacts hydrology utilizing Soil Water Assessment Tool (SWAT) model an ensemble mean five Global Circulation Models (GCMs) under two shared socio-economic pathway (SSP) emission scenarios. Downscaling GCMs performed LARS-WG statistical downscaling tool. In comparison baseline period, short rain intervals are expected occur between 2030 2060, with a annual precipitation increase 7 17% SSP 2–4.5 5–8.5, respectively. Maximum minimum temperatures rise 0.6–2 °C. Corresponding future temperature increases, evapotranspiration would about 30% decrease yield groundwater recharge 26% than 5–8.5. However, effect shown increased surface runoff streamflow wetter months. These findings provide watershed managers crucial information for planning managing catchment light changing climate.

Climate change impacts on hydrology and water resources in East Africa considering CMIP3, CMIP5, and CMIP6

Frontiers in Climate, Год журнала: 2024, Номер 6

Опубликована: Окт. 3, 2024

Climate change impacts on the hydrology and water resources in East Africa require proper planning of regional adaptation measures. Past studies subject matter tended to focus catchment instead scale. To support actionable policy regarding management, this paper reviewed conducted based CMIP3, CMIP5, CMIP6. Compared historical condition, temperature over mid- late 21 st century will increase by varying extents range 0.17–7°C with about 2.6°C average. Future precipitation 8.5% Changes discharge CMIP6 vary from −25.3 +60.5%, −42.5 129%, −23.4 69%, respectively. Ensemble means changes across study area be 25.2, 19.2, 19.1%, peak river 8% These results are important for climate Africa. local or adaptation, temperature, 50 catchments can found summarized review paper. It is recommended that both policies approaches should considered ensure a balanced, effective sustainable framework resilience measures tackling broad specific needs cohesively.
