“…This study emphasizes the use of these two satellite products on an ungauged catchment of the Chenab River in Pakistan. There are a large number of studies [3][4][5][6][7][8][9][10] have been done in sparsely or ungauged catchments using satellite-based products to estimate the river or stream discharges. This study focuses on the catchment of the Chenab River that is completely ungauged.…”

Water resources planning and management depend on the quality of climatic data, particularly rainfall data, for reliable hydrological modeling. This can be very problematic in transboundary rivers with limited disclosing of data among the riparian countries. Satellite precipitation products are recognized as a promising source to substitute the ground-based observations in these conditions. This research aims to assess the feasibility of using a satellite-based precipitation product for better hydrological modeling in an ungauged and riparian river in Pakistan, i.e., the Chenab River. A semidistributed hydrological model of The soil and water assessment tool (SWAT) was set up and two renowned satellite precipitation products, i.e., global precipitation mission (GPM) IMERG-F v6 and tropical rainfall measuring mission (TRMM) 3B42 v7, were selected to assess the runoff pattern in Chenab River. The calibration was done from 2001–2006 with two years of a warmup period. The validation (2007–2010) results exhibit higher correlation between observed and simulated discharges at monthly timescale simulations, IMERG-F (R2 = 0.89, NSE = 0.82), 3B42 (R2 = 0.85, NSE = 0.72), rather than daily timescale simulations, IMERG-F (R2 = 0.66, NSE = 0.61), 3B42 (R2 = 0.64, NSE = 0.54). Moreover, the comparison between IMERG-F and 3B42, shows that IMERG-F is superior to 3B42 by indicating higher R2, NSE and lower percent bias (PBIAS) at both monthly and daily timescale. The results are strengthened by Taylor diagram statistics, which represent a higher correlation (R) and less RMS error between observed and simulated values for IMERG-F. IMERG-F has great potential utility in the Chenab River catchment as it outperformed the 3B42 precipitation in this study. However, its poor skill of capturing peaks at daily timescale remains, leaving a room for IMERG-F to improve its algorithm in the upcoming release.

“…They also demonstrated that a strong correlation at the catchment scale may not necessarily extend to finer spatial scales and suggest that a globally accepted, high-resolution harmonized world land cover dataset could substantially enhance the correlation and confidence in high-resolution ET products. Parajuli et al (2018) and Dash (2018) This study has two main objectives: first, to assess the parameters uncertainty and suitability of discharge and remotely sensed ET to calibrate the SWAT model in the Ilam dam basin. Secondly, to explore the potential of direct calibration against remotely sensed ET data, which is particularly valuable in ungauged basins with limited flow measurements.…”

Complex hydrological processes can be modeled using the Soil and Water Assessment Tool (SWAT). However, poor quality inputs, lack of observation and high number of input parameters make the modeling challenging and complicate the calibration process. The main aim of this study is to assess the parameters uncertainty and suitability of discharge and remotely sensed ET data to calibrate the SWAT model and explore the possibility of using MODIS satellite imagery for direct calibration in ungauged study areas. Different techniques are adopted to acquire accurate land use map and remotely sensed evapotranspiration derived from Sentinel-2 and MODIS satellite imagery. Sobol’ sensitivity analysis is used to effectively identify the key parameters and provides crucial information on how they influence the model outputs. To address model equifinality and uncertainty, the model of the Ilam Dam Basin in Iran is calibrated and validated using a multi-criteria performance evaluation approach that considers all performance criteria concurrently. The discharge predictions at the Sarjoy station showed good discharge predictions during 12 years of calibration (NSE = 0.6, KGE = 0.79, PBIAS = 3.7 and \({R}^{2}\)= 0.64) and 5 years of validation (NSE = 0.5, KGE = 0.76, PBIAS = -0.3 and \({R}^{2}\) = 0.58). ET predictions at the selected HRU also demonstrated acceptable results for calibration (NSE = 0.37, KGE = 0.69, PBIAS = -0.9 and \({R}^{2}\) = 0.47) and validation periods (NSE = 0.47, KGE = 0.73, PBIAS = 0.4 and \({R}^{2}\) = 0.54). The sensitivity analysis shows that while key parameters in both the discharge and ET models exhibited similarity, their varying levels of influence are notable. Furthermore, the direct calibration of the SWAT model yields acceptable performance criteria (NSE = 0.43, KGE = 0.66, PBIAS = -18 and \({R}^{2}\) = 0.61), making it a valuable approach in data-scarce regions.
