Add Tag | Summary: | The Alao and Cebadas micro-basins are located within the Chambo River sub- basin, in the Chimborazo province, Riobamba city and Guamote city respectively, and due to their location, they are on the border between the Chimborazo and Morona Santiago provinces, which is why they are located in high areas, This benefits the fact that a large part of their territorial extension has the characteristics of moorland and that they provide large quantities of water for the Chambo River sub-basin, which can be used in projects to improve the quality of life of the people in the province. For this reason, the present research aims to determine the hydraulic parameters in the Alao and Cebadas micro-watersheds in the Chimborazo province, identifying the use of soil and vegetation cover, the number of bends and the relationship between precipitation and runoff, This will provide information on the water supply in the two micro-watersheds and will allow the use of this resource in projects that help agricultural production, projects for drinking water consumption, irrigation projects and that are carried out in a controlled manner, without exploiting this natural resource. Therefore, satellite images were used which helped us to establish the types of land use and vegetation cover, as well as the sampling points where the in-situ and ex-situ analyses were carried out to determine the hydraulic parameters such as organic matter, porosity, infiltration capacity and infiltration coefficient, The results showed that the Alao river micro-watershed has better hydraulic conditions compared to the Cebadas river, due to the location of both micro- watersheds and the anthropogenic activities that occur in the area. For the modeling using the HEC-HMS software, the parameters described above were used as the SCS curve number method based on daily precipitation data, monthly average evapotranspiration and daily temperature range from 1981-2000 and 2001 to 2021, including the lag time, runoff threshold and CN and other geomorphic data that allow obtaining the daily flow during a certain period of time. In accordance with the above, the results obtained from the hydrological modeling indicate that the average flow of the Alao River microbasin is 0.6590 m3/s, and the average flow of the Cebadas River microbasin is 1.8497 m3/s. On the other hand, the ecological flow refers to the water necessary to preserve ecological conditions in a riverbed, On the other hand, the ecological flow refers to the water necessary to preserve. the ecological conditions in a riverbed; in this sense, the ecological flow of the Alao River is 0.0659 m3/s, and that of the Cebadas River is 0.1849 m3/s. The water concessions of the Alao river are 0.00025 m3/s and those of the Cebadas river are 0.00222 m3/s and the resolution of this research work projects that the water supply for the Alao river is 0.5929 m3/s and for the Cebadas river is 1.66252 m3/s, which indicates that the water supply of both rivers will allow the extraction of water for various activities in the basin as long as this resource is under the proper conditions of controlled use. |
