“…The approach used is similar to the one described in [27][28][29]. This approach depends on a stream power formulation in which the hydraulic radius at each grid cell is related to the upstream catchment area (i.e., the GIS flow accumulation value at the grid cell).…”

“…However, the above routing approaches can depart from reality in large basins with different sub-catchments that contribute at the basin outlet at significantly different times. For such large basins, a time-area unit hydrograph (developed on a short-term basis) can better represent the transforming behavior [27][28][29]. This can blend the powerful accuracy of short-term modeling into the required simplicity of the long-term analysis.…”

“…Part of evapotranspiration in the model is assumed to be implicitly accounted for in the SCS-CN initial abstraction, while the other part is taken as a continuous component from the root zone. Finally, the separated excess and groundwater depths are convoluted at the basin outlet (routed to the basin outlet) using a time-area unit-response approach that is developed on a short-term basis [27][28][29], which can better simulate the real responses of large basins.…”

This study develops a response-based hydrologic model for long-term (continuous) rainfall-runoff simulations over the catchment areas of big rivers. The model overcomes the typical difficulties in estimating infiltration and evapotranspiration parameters using a modified version of the Soil Conservation Service curve number SCS-CN method. In addition, the model simulates the surface and groundwater hydrograph components using the response unit-hydrograph approach instead of using a linear reservoir routing approach for routing surface and groundwater to the basin outlet. The unit-responses are Geographic Information Systems (GIS)-pre-calculated on a semi-distributed short-term basis and applied in the simulation in every time step. The unit responses are based on the time-area technique that can better simulate the real routing behavior of the basin. The model is less sensitive to groundwater infiltration parameters since groundwater is actually controlled by the surface component and not the opposite. For that reason, the model is called the SCHydro model (Surface Controlled Hydrologic model). The model is tested on the upper Blue Nile catchment area using 28 years daily river flow data set for calibration and validation. The results show that SCHydro model can simulate the long-term transforming behavior of the upper Blue Nile basin. Our initial assessment of the model indicates that the model is a promising tool for long-term river flow simulations, especially for long-term forecasting purposes due to its stability in performing the water balance.

“…The average precipitation over the mid-latitude land areas of the Northern Hemisphere has increased since 1901 (IPCC, 2013). In arid and semi-arid regions, runoff which generally originates in mountainous regions and dissipate in piedmont oases is the lifeline for the artificial oases (Zhou, 1999;Foda et al, 2017;Oduor and Mabanga, 2018). Further, the population in catchments is usually sparse, and the influence of human activities on runoff generation is fairly little (Li et al, 2007;Chen et al, 2013;Xu et al, 2013;Chen et al, 2015).…”

The cultivated area in artificial oases is deeply influenced by global climate change and human activities. Thus, forecasting cultivated area in artificial oases under climate change and human activities is of great significance. In this study, an approach named GD-HM-PSWROAM, consisting of general circulation model downscaling (GD), hydrological model (HM), and planting structure and water resource optimal allocation model (PSWROAM), was developed and applied in the irrigation district of the Manas River Basin in Xinjiang Uygur Autonomous Region of China to forecast the cultivated area tendency. Furthermore, the catchment export of the MIKE11 HD/NAM model was set to the Kensiwate hydrological station. The results show that the downscaling effects of temperature can be fairly satisfying, while those of precipitation may be not satisfying but acceptable. Simulation capacity of the MIKE11 HD/NAM model on the discharge in the Kensiwate hydrological station can meet the requirements of running the PSWROAM. The accuracy of the PSWROAM indicated that this model can perform well in predicting the change of cultivated area at the decadal scale. The cultivated area in the Manas River Basin under current human activities may be generally decreasing due to the climate change. But the adverse effects of climate change can be weakened or even eliminated through positive human activities. The cultivated area in the Manas River Basin may even be increasing under assumed human activities and future climate scenarios. The effects of human activities in the future can be generally predicted and quantified according to the cultivated area trends under current human activities and the situations in the study area. Overall, it is rational and acceptable to forecast the cultivated area tendency in artificial oases under future climate change and human activities through the GD-HM-PSWROAM approach.
