Dynamics of CO2 Density‐Driven Flow in Carbonate Aquifers: Effects of Dispersion and Geochemistry Water Resour. Res. (IF 4.309) Pub Date : 2021-02-24 Hamidreza Erfani; Masoud Babaei; Vahid Niasar
The dissolution of carbon‐dioxide (CO2) in deep saline aquifers is an important trapping mechanism in carbon storage. This process is triggered by unstable high‐density CO2 front, which later promotes density‐driven mixing, hydrodynamic dispersion of CO2 and favours the long‐term sequestration. In many former studies, effects of hydrodynamic dispersion and multispecies geochemical reactions have been

Does the Hook Structure Constrain Future Flood Intensification Under Anthropogenic Climate Warming? Water Resour. Res. (IF 4.309) Pub Date : 2021-02-01 Jiabo Yin; Shenglian Guo; Pierre Gentine; Sylvia C. Sullivan; Lei Gu; Shaokun He; Jie Chen; Pan Liu
Atmospheric moisture holding capacity increases with temperature by about 7% per °C according to the Clausius‐Clapeyron relationship. Thermodynamically then, precipitation intensity should exponentially intensify and thus worsen flood conditions as the climate warms. However, regional and global analyses often report a nonmonotonic (hook) scaling of precipitation and runoff, in which extremes strengthen

The estimation of evaporation in the field as well as the regional level is required for the efficient planning and management of water resources. In the present study, artificial neural network (ANN) and multiple linear regression (MLR)-based models were developed to estimate the pan evaporation on the basis of one day-lagged rainfall (Pt−1), one day-lagged relative humidity (RHt−1), current day maximum

Cost-benefit of promising adaptations for resilient development in climate hotspots: evidence from lower Teesta basin in Bangladesh J. Water Clim. Chang. (IF 1.254) Pub Date : 2021-02-01 Md. Arfanuzzaman; S. M. Tanvir Hassan; Md. Abu Syed
It is very likely that climate change will increase the frequency and intensity of extreme events such as floods, flash floods, storms, heat and cold waves, riverbank erosion, and drought in the river basin of Hindu Kush Himalayan (HKH) region. This could mean detrimental impacts to the poor and marginal people in the lower Teesta basin (LTB) in Bangladesh. Though adaptation involves financial costs

Impact of projected 21st century climate change on basin hydrology and runoff in the Delaware River Basin, USA J. Water Clim. Chang. (IF 1.254) Pub Date : 2021-02-01 Timothy W. Hawkins; Christopher J. Woltemade
A gridded hydrologic model was developed to assess the impact of projected climate change on future Delaware River Basin (DRB) hydrology. The DRB serves as a water supply resource to over 15 million people. Model evaluation statistics for both water year and monthly runoff projections indicate that the model is able to capture well the hydrologic conditions of the DRB. Basinwide, annual temperature
