Investigation of drought that has heavy sociological and economical costs to countries is very important to alleviate its adverse impacts and to take the necessary precautions. Konya Closed Basin, which has critical role in terms of agricultural yield for our country, is one of the regions where the impact of the drought is felt the most due to its semi-arid climate. For this reason, in this study, severity, duration, and impact area of drought is analyzed over Konya Closed Basin between 1998 and 2015. In these analyses, precipitation maps derived using Tropical Rainfall Measuring Mission (TRMM) Multi-Satellite Precipitation Analysis ( TMPA) 3B42 v7 satellite-based raw precipitation product provided by National Aeronautics and Space Administration (NASA) are used. Results show seven long dry periods occurred during the past 18 years, while the December 2006 - October 2007 period had the most severe drought in terms of severity and impact area. The temporal propagation of drought results are consistent with the results of drought studies that have used station-based precipitation data. This study also presents the high potential of remote sensing-based precipitation datasets in drought analyses, particularly in drought impact area calculations.

Drought Forecasting with Time Series and Machine Learning Approaches Evkaya, Ömer Ozan; Yozgatlıgil, Ceylan; Kestel, Sevtap Ayşe (null; 2017-12-08) As a main reason of undesired agricultural, economic and environmental damages, drought is one of the most important stochastic natural hazard having certain features. In order to manage the impacts of drought, more than 100 drought indices have been proposed for both monitoring and forecasting purposes [1], [3]. For different types of droughts, these indices have been used to understand the effects of dry periods including meteorological, agricultural and hydrological droughts in many distinct locations. I...
Extreme precipitation and drought monitoring in northeastern China using general circulation models and pan evaporation-based drought indices Faiz, Muhammad Abrar; Liu, Dong; Fu, Qiang; Wrzesinski, Dariusz; Baig, Faisal; Nabi, Ghulam; Khan, Muhammad Imran; Li, Tianxiao; Cui, Song (2018-01-01) The evaluation of precipitation extremes and the usage of appropriate drought indices are very important for assessment of natural disasters (i.e. floods and drought). For this purpose, we calculated values of indices that reflect precipitation extremes and 3 drought indices, i.e. the composite index (CI), standardized precipitation evapotranspiration index (SPEI), and reconnaissance drought index (RDI), with reformulation of pan evaporation and Penman-Monteith equations (denoted as CI-Pan, RDI-Pan, RDI-PM,...
Drought analysis using CORDEX simulations over the mediterranean climate regions of Turkey Poyraz, Anıl Yıldırım; Yücel, İsmail; Department of Civil Engineering (2018) Drought has been a significant result of climate change that causes variance on precipitation regimes. Mediterranean region is one of the hotspots of the world in this respect. Dry summers and rainy winters -the characteristic of this climate type- makes this region more vulnerable to the effects of climate change. Hence, it is important to monitor drought considering the increasing population and economic facilities in the regions that are under Mediterranean climate conditions in Turkey. This study aims t...
Gene regulation network behind drought escape, avoidance and tolerance strategies in black poplar (Populus nigra L.) Yildirim, Kubilay; Kaya, Zeki (2017-06-01) Drought is the major environmental problem limiting the productivity and survival of plant species. Here, previously identified three black poplar genotypes having contrasting response to drought were subjected to gradual soil water depletion in a pot trial to identify their physiological, morphological and antioxidation related adaptations. We also performed a microarray based transcriptome analyses on the leaves of genotypes by using Affymetrix poplar Genome Array containing 56,000 transcripts. Phenotypic...
Disaster Losses in the Developing World: Evidence from the August 1999 Earthquake in Turkey Özdemir, Özlem (SerialSSolutions, 2004-06-01) The purpose of this study is to investigate the impacts of a natural disaster on a developing country’s economy. In that sense, we look at the impact of August 1999 earthquake in Turkey on two important macroeconomic indicators of the Turkish economy (Real Output and Employment) with recovery policies followed by the government and international donors. Our results indicate that the earthquake had a significant immediate negative impact on both output and employment growth in Turkey. While output growth re...
