ABSTRACT CALARANAN, GUEENIE ROSE P. GABRIEL JAYSON G. GALIZA SARAH JANE M.2828. Modeling the Hydrologie Response of Colt River Watershed to Rainfall Variability Using Soil and Water Assessment Tool Plus (WAT Undergraduats Thesis Mariano Marcos State University, City of Batac, Jilocos carte. 136 pp. Adres Du Nathaniel R. Alig Throughout the last few decades, climate change has led to changing weather Dette and modifying weather rate, exacerbating hydrological cycles, and leading to the cycles volatility and instability Water supplies have been decreasing due to increasing weather temperature (e global warming). The use of hydrological models such as SWAT today is beneficial in assessing the impact of climate change on wwerhed hydrology. These understandings are crucial for water assessment, anagement, and to put appropriate adaptation. This study was designed to simulate the hydroderie responses of Quest River Watershed (ORW) in the City of Batac. Il Norte, though the Soil and Water Assessment Tool (SWAT). Streamflow was then used to calibrate the model. The calibration exhibited a good match between nerves and simulated streamflow with a Nash and Sutcliffe coefficient (NSE) from 0 30 0 0.50. As such, the model can be proven to be useful in simulating the yogic water balance of the watershed as affected by various climatic scenarios. Results have shown that the changes in the climatic condition of the watershed are expected to happen in the next years. With the projection of medium and high range, there will be a decrease in the amount of rainfall by 0.11% and 0.08%, respectively. There will also be a significant decrease in the amount of surface runoff, baseflow, and water yield by 0.18%, 0.1%, and 0.15%, respectively for medium-range scenario. As per high-range, runoff will decrease by 0.11%, baseflow will decrease by 0.07%, and water yield for about 0.01% decrease. The increase in temperature however, makes the rate of evapotranspiration faster by 0.04% for medium-range and 0.05% for high-range. A deficit in the water reserve of the watershed in the next years is most likely to happen. Hydrologic behavior, therefore, changes as it responds to changes climate. While simulation results must undergo further validation, the study demonstrated that the Soil and Water Assessment Tool Plus (SWAT+) model could be a useful tool in assessing different problems regarding climate change scenarios. The results of the study can serve as a basis for developing appropriate interventions to attain water security and sustainability in the watersheds. |
