Hello, good after noon, today | am going to explain the Revealing impacts of climate change on mountainous catchments through high-resolution modelling this information was taken from ScienceDirect Group member just me l'm going start with the introduction. As we all know, global warming is affecting all types of natural habitat, in this case it affects the hydrological processes which are dangerous both for humans and for flora and fauna, causing overflows, floods,droughts,which are linked to a hydrological cycle directly affected by global warming I'm to going to talk about the hydrological models that they used, as AWE-GEN-2 and Topkapi-ETH this hydrological models are used to modelling watersheds, and the watershed calculated in this experiment are the watershed of Thur and Kleine, are ubicate in Switzerland, thur ¡is located in northeaster and kleine ¡is located in central Switzerland. For calculate this kind of aftections we have to follow some steps, and the primary steps are 1. Study area and data 2. Weather generator 3. Hydrological model 4. Experimental design 1. areas and data + These watershed are outside the limits of glaciers or artificial watershed,the thur has an area of 1730 square km and an elevation range between 359 and 24 34 m and the average temperature is 87 degrees with a flow rate of 46.7 cubic meters , + The Kleine Emme catchment has a total drainage area of 477 km2 and an elevation range between 430 and 2330 m and the temperature is 90 degrees Fahrenheit and has a flow rate of 12.6 cubic meters 2. Weather generator Using the meteorological data of the basins, the AWE-GEN-2 model is projected to make multiple traces in series with high resolution of the climatic variables that are of great importance for the hydrological model That includes precipitation, cloud cover and the air temperature near the surface at 2 m above the ground 3. Hydrological model The Topkapi-ETH model was applied to quantify the hydrological response of river basins to climate change .topkapi-ETH was selected because it represents a reasonable compromise between a completely physics-based representation of hydrological processes and computational time for large domains allowing high resolution 4. Experimental design The experiment carried out in this study consisted of simulating large climate data sets which were used as inputs to Topkapi-ETH to obtain present and future hydrological variables simulated both models. 1. were independently calibrated to simulate climatic and hydrological variables for current climatic conditions. The meteorological model was Calibrated and validated using climatic observations obtained between 1982 and 2015. 2. FC data for temperature and precipitation were obtained using the results of the simulations of the climatic models corresponding present and future periods 3. hydrological ensembles were simulated to obtain squared data sets, evapotranspiration and soil moisture, and point simulations of flow at junctions of the river network of the river basins in Kleine Emme and Thur. the results expressed in this slide were summarized
