fish biodiversity investigation in urmia basin which is a part of irano-anatolian hot spot aimed to determine the state of fish in this endorheic basin. based on the obtained results, freshwater fish species of the urmia basin comprise 29 species in 25 genera, 7 families, 5 orders and one class. the most diverse order is the cypriniformes with 23 species (79.31%) followed by salmoniformes and p...

In this study, the performance of three empirical methods for estimating reference evapotranspiration (ET0): Makkink (Mak) and PriestleyeTaylor (PT) (radiation-based) and HargreaveseSamani (HARG) (temperature-based) were assessed in semi-arid regions. The values of ET0 derived using these three methods were compared to those estimated using the reference FAO PenmaneMonteith (FAO-PM) method unde...

A new family of exact solutions is analysed, which models two-dimensional circulations of an ideal fluid in a uniformly rotating elliptical tank, under the semi-geostrophic approximation from meteorology and oceanography. The fluid pressure and stream function remain quadratic functions of space at each instant in time, and their fluctuations are described by a single degree of freedom Hamilton...

Irrigation is one of the main users water worldwide and its overuse may affect natural regimes systems. To avoid this, drainage irrigation management needs to be improved. This study aims determine amount lost in a semi-arid Mediterranean irrigated area. Water use, rainfall were monitored for 12 months (2019–2020) 425 ha sub-basin Algerri-Balaguer district (8000 ha, NE Spain). In addition, requ...

This paper investigates the internal tidal energy distribution in the southwestern Japan/East Sea using vertical round-trip travel time (τ) data from 23 pressure-sensor-equipped inverted echo sounders (PIESs). The τ records are analyzed by band-pass filtering to separate time-dependent variability of the semi-diurnal and diurnal bands. The semi-diurnal internal tides exhibit a horizontal beam p...
