Adler, Robert; Gu, Guojun; Zhou, Naijun; Wu, Huan; Matgen, Patrick; Galantowicz, John; Schumann, Guy; Yılmaz, Koray Kamil (2022-08-01)
The application and value of the Global Flood Monitoring System (GFMS) andvarious remote-sensing-based flood products are examined in the context ofthe severe flood event in Mozambique associated with Cyclone Idai in March...
Production of a high-resolution improved radar precipitation estimation map using gauge adjustment bias correction methods
Yousefi, Kaveh Patakchi; Yılmaz, Mustafa Tuğrul; Ozturk, Kurtulus; Yücel, İsmail; Yılmaz, Koray Kamil (null; 2020-05-08)
This study evaluates relative performances of different statistical algorithms to enhance radar-based quantitative precipitation estimation (QPE) accuracy using rain gauge network data. Initial investigations are implement...
Performance evaluation of satellite- and model-based precipitation products over varying climate and complex topography
Amjad, Muhammad; Yılmaz, Mustafa Tuğrul; Yücel, İsmail; Yılmaz, Koray Kamil (Elsevier BV, 2020-05-01)
Accuracy assessment of precipitation retrievals is a pre-requisite for many hydrological studies as it helps to understand the source and the magnitude of the uncertainty in hydrological response variables, particularly ov...
A multi-technique approach to determine temporal and spatial variability of groundwater-stream water exchange
Koruk, Kasimcan; Yılmaz, Koray Kamil; Akyürek, Sevda Zuhal; Binley, Andrew (Wiley, 2020-04-03)
Characterizing the spatio-temporal distribution of groundwater-surface water (GW-SW) exchange fluxes is of paramount importance in understanding catchment behavior. A wide range of field-based techniques are available for ...
