“…The effect of the parameters on the simulated streamflow was evaluated with p-value which determines the significance of the sensitivity and t-stat which provide a measure of sensitivity. The ranking of most sensitive parameters observed in this study (Table 5) was also supported by the findings of Raposo et al, (2013) [55] in the LRB and Senent-Aparicio et al, (2017) [26] in the HSRB. Some of the most sensitive parameters are common for both basins with a similar order of sensitivity, as for example ALPHA_BF, CH_N1, CH_N2, SOL_K, CN2 and GWQMN.…”

“…When the ESCO value decreases, the ability of the model to extract the evaporative demand from lower soil layers increases [58]. Lateral flow travel time (LAT_TTIME) in the LRB was very similar to that used by Raposo et al, (2013) [55] in nearby basins where a significant portion of groundwater flows laterally as interflow [59]. The value of GWQMN was calibrated as 82.5 in LRB similar to that obtained in a nearby study [55].…”

“…After performing a global sensitivity analysis, the most sensitive parameters were selected for each studied basin, which are shown and defined in Table 6. All the selected parameters were also selected as the most relevant in other research [23,26,41,55]. The fitted values of these parameters reflect the contrasting climatic characteristics of the two basins.…”

Besides, an automated digital filter programme (Base Flow Filter Program) [60] was applied to determine the groundwater ratio.…”

Streamflow data are of prime importance to water-resources planning and management, and the accuracy of their estimation is very important for decision making. The Soil and Water Assessment Tool (SWAT) and Artificial Neural Network (ANN) models have been evaluated and compared to find a method to improve streamflow estimation. For a more complete evaluation, the accuracy and ability of these streamflow estimation models was also established separately based on their performance during different periods of flows using regional flow duration curves (FDCs). Specifically, the FDCs were divided into five sectors: very low, low, medium, high and very high flow. This segmentation of flow allows analysis of the model performance for every important discharge event precisely. In this study, the models were applied in two catchments in Peninsular Spain with contrasting climatic conditions: Atlantic and Mediterranean climates. The results indicate that SWAT and ANNs were generally good tools in daily streamflow modelling. However, SWAT was found to be more successful in relation to better simulation of lower flows, while ANNs were superior at estimating higher flows in all cases.

“…Several researches have evaluated the effects of climate change on river regimes in the Iberian Peninsula [10][11][12], but few studies have been conducted in North-Western Spain [13]. In this area, especially in Galicia, most rivers have little or no flow data available for such analyses.…”

Assessment of the diverse responses of water resources to climate change and high concentrations of CO2 is crucial for the appropriate management of natural ecosystems. Despite numerous studies on the impact of climate change on different regions, it is still necessary to evaluate the impact of these changes at the local scale. In this study, the Soil and Water Assessment Tool (SWAT) model was used to evaluate the potential impact of changes in temperature, rainfall and CO2 concentration on water resources in a rural catchment in NW Spain for the periods 2031-2060 and 2069-2098, using 1981-2010 as a reference period. For the simulations we used compiled regional climate models of the ENSEMBLES project for future climate input data and two CO2 concentration scenarios (550 and 660 ppm). The results showed that changes in the concentration of CO2 and climate had a significant effect on water resources. Overall, the results suggest a decrease in streamflow of 16% for the period 2031-2060 (intermediate future) and 35% by the end of the 21st century as a consequence of decreasing rainfall (2031-2060: −6%; 2069-2098: −15%) and increasing temperature

Assessing the impacts of climate change on water quantity and quality modelling in small Slovenian Mediterranean catchment - lesson for policy and decision makers

The study aims to address the long‐term impacts of six different downscaled Regional Climate Models (RCM) climate models on the quantity (river flow) and quality (sediment load, total nitrogen load and total phosphorus load) state of surface waters in the river Reka catchment, in the northern Mediterranean. Mediterranean areas are – due to high population density, favourable natural conditions for agriculture, limited water resources, diverse ecosystems biodiversity and expected climate change impacts – a global hotspot in climate research. Additionally, the study area lies on the border with the alpine climate zone, with a strong orographic effect on weather patterns. The location, and a wide range of studied parameters, provides an interesting insight into how various emerging climate change models may impact the status of surface waters and procedures for the governance of water resources. The study contributes to the knowledge and understanding of the climate change impact on the local catchment level, using the ensemble of the RCMs. It opens discussion about the impact of RCM selection on modelling climate changes with catchment models like Soil and Water Assessment Tool. This article also questions the usability of the results for the policy and decision makers in relation to the implementation of the results into short or long‐term water strategies or water/river management plans.
