Drought indices and indicators revisited
(Springer Heidelberg, 2019)
There are numerous drought indicators used by decision makers all around the globe which have been developed to fulfill specific needs. By far, risks associated with drought and related consequences have become a bold topic ...
Interaction of groundwater with Lake Urmia in Iran
(Wiley, 2018)
Being a large hyper-saline water body, Lake Urmia in north-western Iran deals with a gradual decline in its water level. Most of the studies on Lake Urmia have neglected the groundwater issue. In this study, as a direct ...
Temporal dynamics of monthly evaporation in Lake Urmia
(Springer Wien, 2019)
As a UNESCO biosphere, Lake Urmia is a shallow hypersaline lake which is facing a rapid water surface degradation. Evaporation from the surface of the Lake, as a physical process which accelerates the Lake's degradation, ...
A Spatiotemporal Classification of the Peruvian Precipitations Between 1990 and 2015
(Springer Basel Ag, 2020)
Precipitation and its variations have great importance in water resource management and sustainable development. In this study, the Peruvian precipitations between January 1990 to October 2015, were used. The precipitations ...
Identification of the trends associated with the SPI and SPEI indices across Ankara, Turkey
(Springer Wien, 2020)
This study investigates the main characteristics (duration, severity, and trend) of meteorological drought events over Ankara Province, Turkey. We used 46 years of observed monthly precipitation and temperature series from ...
Reconstruction of Hydrometeorological Data in Lake Urmia Basin by Frequency Domain Analysis Using Additive Decomposition
(Springer, 2019)
Frequency domain analysis using an additive decomposition method is proposed to reconstruct the missing hydrometeorological data of selected sites in Lake Urmia basin in Iran. Precipitation, evaporation, streamflow and ...
Application of hybrid ANN-whale optimization model in evaluation of the field capacity and the permanent wilting point of the soils
(Springer Heidelberg, 2020)
Field capacity (FC) and permanent wilting point (PWP) are two important properties of the soil when the soil moisture is concerned. Since the determination of these parameters is expensive and time-consuming, this study ...
A spatiotemporal teleconnection study between Peruvian precipitation and oceanic oscillations
(Pergamon-Elsevier Science Ltd, 2020)
Large-scale oceanic oscillations and their teleconnections with meteorological events are of great importance in macro-scale climatic studies. In this regard, this study investigates the spatiotemporal teleconnections ...
ENN-SA: A novel neuro-annealing model for multi-station drought prediction
(Pergamon-Elsevier Science Ltd, 2020)
This paper presents a new hybrid model, called ENN-SA, for spatiotemporal drought prediction. In ENN-SA, an Elman neural network (ENN) is conjugated with simulated annealing (SA) optimization and support vector machine ...
Parametric and nonparametric regression models in study of the length of hydraulic jump after a multi-segment sharp-crested V-notch weir
(Iwa Publishing, 2020)
A multi-segment sharp-crested V-notch weir (SCVW) was used both theoretically and experimentally in this study to evaluate the length of the hydraulic jump at the downstream of the weir. For this aim, a SCVW with three ...
