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 ...

The great success of the Tropical Rainfall Measuring Mission (TRMM) and its successor Global Precipitation Measurement (GPM) has accelerated the development of global high-resolution satellite-based precipitation products ...
Evaluation of gauge adjustment methods in improving radar precipitation estimation quality over Antalya radar in Turkey.
Yousufi, Kaveh Patakchi; Yılmaz, Mustafa Tuğrul; Ozturk, Kurtulus; Yücel, İsmail; Yılmaz, Koray Kamil (null; 2019-11-28)
Radar-based precipitation estimates rely on algorithms that utilize observations of backscattered waves sent from the radar. By utilizing these backscattered observations and different reflectivity-rainfall (Z-R) equations...
Twenty-three unsolved problems in hydrology (UPH) - a community perspective
Bloeschl, Gunter; et. al. (Informa UK Limited, 2019-07-01)
This paper is the outcome of a community initiative to identify major unsolved scientific problems in hydrology motivated by a need for stronger harmonisation of research efforts. The procedure involved a public consultati...
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...
Inter-comparison and Accuracy Assessment of Satellite and Model Precipitation Products
Amjad, Muhammad; Yılmaz, Mustafa Tuğrul; Yücel, İsmail; Yılmaz, Koray Kamil (null; 2018-04-08)
It is important to quantify the reliability of satellite and model precipitation products before utilizing them in water resources assessment. This study inter-compares TRMM-era and GPM-era satellite-based precipitation pr...
Evaluation of GRACE based groundwater storage change information at Konya Closed Basin Turkey using remote sensing and in situ measurements
Yılmaz, Koray Kamil; Saber, Mohamed; Yılmaz, Mustafa Tuğrul (null; 2016-12-12)
The Konya Closed Basin (KCB) located in Central Anatolia, Turkey, is the primary grain producer in Turkey and covers an area of approximately 50000km2. The lack of sufficient surface water resources and recently changing c...
Estimation of Radar Based High Resolution Precipitation Product over Turkey
Yılmaz, Mustafa Tuğrul; Öztürk, Kurtuluş; Yücel, İsmail; Yılmaz, Koray Kamil (2016-10-10)
Precipitation is one of the most critical variables in many hydrometeorological applications such as drought and flood monitoring, climate change impact studies and water resources management. Particularly flood analysis a...
