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 ...

A Multi-Scale Approach for Improved Characterization of Surface Water-Groundwater Interactions: Integrating Thermal Remote Sensing and in-Stream Measurements
VARLI, Dilge; Yılmaz, Koray Kamil (2018-07-01)
The interaction between surface water and groundwater is recognized as a key process for effective management of water resources. However, scale dependency and spatial heterogeneity of the processes at the interface are li...
Evaluation and Bias Correction of Satellite-Based Rainfall Estimates for Modelling Flash Floods over the Mediterranean region: Application to Karpuz River Basin, Turkey
Saber, Mohamed; Yılmaz, Koray Kamil (MDPI AG, 2018-05-01)
This study investigates the utility of satellite-based rainfall estimates in simulating flash floods in Karpuz River Basin, Turkey, characterized by limited rain gauge network. Global Satellite Mapping of Precipitation (GS...
