ANALYZING THE COMBINED IMPACT OF CLIMATE AND LAND USE LAND COVER CHANGE ON THE HYDROLOGICAL RESPONSE OF JHELUM RIVER BASIN IN KASHMIR

2022-7
Hamid, Injila
In terms of efficient and sustainable management of water resources of a basin, land use land cover (LULC) and climate change impact studies hold utmost importance. Land use change dynamics along with the climate change owing to greenhouse gas emissions are altering the hydrological response of river basins. This study therefore focuses on quantifying the combined impact of LULC and climate change on the water balance components of the Jhelum river basin using Soil and Water Assessment Tool (SWAT) hydrological model. In the analysis, SWAT-CUP (SUFI-2 algorithm) was employed to calibrate and validate the model using Nash-Sutcliffe Efficiency (NSE) as the objective function. Model performance was evaluated using statistical parameters such as R2, NSE, PBIAS and KGE that demonstrated satisfactory results. Future projections of climate change using bias corrected NorESM1-M model have also been utilized in this study under medium emission RCP 4.5 and high emission RCP 8.5 radiative forcing to estimate the changes in mean annual temperature and precipitation during mid (2041 – 2070) and end of the 21st century (2071 – 2100) in the Jhelum river basin. Moreover, projected future hydrological response of the basin as a result of this climate change has been quantified in terms of the changes exhibited by the water balance components of the basin using SWAT model.

Rapid changes in land use land cover (LULC) adversely affect the environment. In order to provide information for policymakers to support sustainable development, detailed data about these regions is urgently needed. Use of remote sensing (RS) in combination with geographical information System (GIS) is one of the effective information technology tools to generate LULC change information. In this study, it is aimed to explore the temporal and spatial characteristics of urban expansion by using RS integrated...
Understanding Groundwater And Surface Waterexchange Processes Along A Controlled Stream Using Thermal Remote Sensing And in Situ Measurements
Varlı, Dilge; Yılmaz, Koray Kamil (2016-12-16)
Effective management of water resources requires understanding and quantification of interaction between groundwater and surface water bodies. Moreover, the exchange processes have recently received increasing attention due to important influences on biogeochemical and ecological status of watersheds. In this study we investigated the exchange processes between surface water and groundwater along Kirmir stream - a controlled stream nearby Kizilcahamam, Ankara, Turkey. At the first stage, potential stream re...
Hierarchical approach to hydrological model calibration
ÖZDEMİR, Ayfer; Leloğlu, Uğur Murat; ABBASPOUR, Karim C. (2017-04-01)
Hydrological models have been widely used for water resources management. Successful application of hydrological models depends on careful calibration and uncertainty analysis. Spatial unit of water balance calculations may differ widely in different models from grids to hydrological response units (HRU). The Soil and Water Assessment Tool (SWAT) software uses HRU as the spatial unit. SWAT simulates hydrological processes at sub-basin level by deriving HRUs by thresholding areas of soil type, land use, and ...
Evaluation of the best management practices in a semi-arid region with high agricultural activity
Özcan, Zeynep; Kentel Erdoğan, Elçin; Alp, Emre (Elsevier BV, 2017-12)
The arid and semi-arid regions with water scarcity are vulnerable to several stressors such as urbanization, high water demand created by agricultural and industrial activities, point and non-point pollution sources, and climate change. Hence, proactive policies and sustainable water management strategies that are based on decision support systems are crucial in arid and semi-arid regions. Because of large expenses and implementation difficulties associated with the diffuse pollution abatement plans, many a...
Quantifying the effects of climate change on hydrological regime and stream biota in a groundwater-dominated catchment: A modelling approach combining SWAT-MODFLOW with flow-biota empirical models
Liu, Wei; Bailey, Ryan T.; Andersen, Hans Estrup; Jeppesen, Erik; Nielsen, Anders; Peng, Kai; Molina-Navarro, Eugenio; Park, Seonggyu; Thodsen, Hans; Trolle, Dennis (Elsevier BV, 2020-11-01)
Climate change may affect stream ecosystems through flow regime alterations, which can be particularly complex in streams with a significant groundwater contribution. To quantify the impacts of climate change on hydrological regime and subsequently the stream biota, we linked SWAT-MODFLOW (A model coupling the Soil and Water Assessment Tool and the Modular Finite-difference Flow Model) with flow-biota empirical models that included indices for three key biological taxonomic identities (fish, macroinvertebra...
