“…Indeed, evaluation of the effect of climate change on the flow field through the short, medium and long term is a requirement for a wide range of practical applications [1][2][3][4][5]. This study proves the applicability of the developed models in [6][7][8][9] for evaluation of flow hydrodynamics under changing climate. To this end, we consider the Gulf as an area of interest.…”

“…In order to consider the impact of climate change on the flow hydrodynamics, we consider the changes of wind speed, as one of the most important variables in deriving the flows and waves on estuaries. To this end, the Quantile-Quantile downscaling method, described in [6], is used to project the wind speed over the Qatar coastal areas. A multi-model multi-scenario approach has been employed to take into account the uncertainties associated with the GCM outputs.…”

“…As one of the most important climate variables which affects the flow field, we consider the wind speed to be projected within the future time spans. In line with this goal, we use the developed Quantile-Quantile downscaling method [6] to predict the wind speed over the coastal areas of Qatar. We use the historical data at the Doha International Airport together with the various GCM outputs under different RCP emission scenarios to develop the downscaling method.…”

The main objective of this paper is to model the flow hydrodynamics over the Gulf for the next decades with consideration of the climate change. The large scale triangular finite volume C-grid scheme was implemented in a large scale hydrodynamic model of the Gulf. The large scale model is validated using the observed water levels at WAKRAH and UMMSAID. Then, by employing the developed positivity preserving well-balanced central-upwind scheme the flow over a local coastal area along the Qatar coast is simulated. The outputs of the large-scale model are used as the boundary conditions for the local hydrodynamic model. Downscaled wind speed under different RCP scenarios are also used as an input into the local flow model. The results of flow field under the climate change can be implemented for a wide range of practical applications, from mixing of industrial outfalls to designing and maintaining coastal structures.

“…This adjustment (correction) is applied to the future data. The downscaling code was previously developed by Seidou, Ramsay, and Nistor () and Shirkhani, Seidou, Mohammadian, and Qiblawey (). That code was modified to read in CanRCM4 RCP format precipitation and to implement linear interpolation between quantiles for data that do not map directly to a quantile value.…”

The response of the semi-alluvial clay-bed Watts Creek is assessed subject to climate change.Climate impacts are expected to have regional variability, and few studies have assessed the impacts of future climate in a small urban watershed. The 21-km 2 watershed located in Ottawa, Ontario, Canada, is highly urbanized (68%) and agricultural (20%) with limited forest cover (12%).Continuous simulations were performed using the SWMHYMO lumped hydrologic modelling platform for the open water year, excluding spring freshet (April 1 to October 31). A shear stress exceedance and stream power erosion routine was added to the platform to calculate erosion potential. To account for uncertainty in the collected data, 9 different field datasets were used to calibrate the model, each leading to a distinct set of calibrated parameter values. The difference between the datasets lies in the choice of the rating curves and calibration period.The 2041-2080 precipitation outputs of the 4th version of the Canadian Regional Climate Model (CanRCM4) ran under representative concentration pathways (RCPs) 4.5 and 8.5 at the MacDonald Cartier International Airport were downscaled using quantile matching and then used as input to the continuous hydrologic model. For each set of calibrated parameters, a cumulative effective work index based on the reach-averaged shear stress was calculated for Watts Creek using both the historic and projected future (2041-2080) flows, using a bed material critical shear stress for entrainment of 3.7 Pa. These results suggest an increase of 75% (respectively 139%) under RCP4.5 (respectively RCP8.5) in cumulative effective work index compared with historic conditions for the average measured bed strength. The work index increase is driven by an increased occurrence of above-threshold events and, more importantly, by the increased frequency of large events. The predicted flow regime under climate change would significantly alter the erosion potential and stability of Watts Creek.
