İklim değişikliği, kuraklık gidişinin alansal ve zamansal yayılımının izlenmesinde farklı yaklaşımları ortaya konarak analitik çözümlemeleri ihtiyaç haline getirmiştir. Güneydoğu Anadolu Projesi (GAP) kapsamında; 19 242 km²’lik büyüklüğü ile sulama alanlarının %50’sine sahip Şanlıurfa’da yürütülen bu çalışmada, yöntemler kullanılarak meteorolojik kuraklığın alansal-zamansal eğiliminin büyüklüğü...
a study of changes in groundwater resources of najafabad plain is an important issue asregards water resources management, especially after dry becoming of zayandehroodriver. in the present study trend analysis was conducted on groundwater level of 33piezometeric stations, located in najafabad plain during 1374-1391 while using mann-kendall non-parametric test. the slope of trend line was estim...
Environments with a climatic characteristic of semi-aridity exhibit high rainfall variability, increasing significantly as the climate changes. In this study, concentration and Spatio-temporal trends in annual seasonal (November to March) Botswana were analyzed. The satellite data (1958-2019) is obtained from Southern African Science Service Centre for Climate Change Adaptive Land Management To...
This study performs trend analysis of hydroclimatic varibles and their possible effects on the water resources variability. Nonparametric Mann-Kendall and spearman tests were used to investigate trend analysis of mean annual and 24-hr maximum rainfall, flood and low flow parameters of 23 hydrometery and 18 synoptic stations in Sefid-Roud basin. The results showed that mean annual and 24-hr rain...
In arid and semi-arid ecosystems shortage of surface water has led to a greater use of groundwater resources. Water table in groundwater due to climate and human intervention is always fluctuating. Assessing change groundwater resource in planning and sustainable management of water resources in each region has of great importance. In this study were investigated changes of water table in the p...
Abstract The identification of hydro-meteorological trends is essential for analyzing climate change and river discharge at the watershed level. Ajora-Woybo in Ethiopia was studied long-term rainfall, temperature, annual, monthly, seasonal time scales. rainfall temperature data extend 1990 to 2020, whereas span from1990 2015. Pettitt Standard Normal Homogeneity Test (SNHT) tests were used deter...
As a Semi-arid country, Burkina Faso is highly vulnerable to climate-related disasters such as drought and flood. Analyzing signature therefore key factor in advocating climate change adaptation at the local scale. In this study, Spatiotemporal trends of were conducted for period 1960–2021 within Massili Basin using standardized precipitation evapotranspiration index (SPEI) package R. The non-p...
