In addition to the three so far known species of Prosopistoma Latreille, 1833 from West Palaearctic region, P. pennigerum (Müller, 1785), P. oronti Alouf, 1977 and P. orhanelicum Dalkıran, 2009, two new species are described based on larvae. Prosopistoma helenae sp. n. has been found in Iraq (Tigris River in Mosul) and Prosopistoma alaini sp. n. in Algeria (Oued Isser, Sidi Abdelli). Critical d...

Tigris, are widespread in west of Iran and lives mostly in river and lake. They are omnivorous fish. This study aims to investigate population structure of C. reginus using Principal component Analysis. The study was conducted in three rivers that is the most remote headstream of the Gamasiab River in west part of Iran. Seven quantitative traits were measured for each specimen. After logarithmi...

This paper examines the ramifications of late twentieth century water management schemes–especially those initiated by the Republic of Turkey–for the riparians of the Tigris and Euphrates rivers. The Turks’ geographical position, and their ability to construct large water storage systems, has essentially given them command of the headwaters of the Euphrates and, to a lesser degree, the Tigris. ...

Baghdad Metro is a vital project to fulfill the rapidly increased traffic volume requirements. The proposed metro will connect both sides of City, passing under Tigris River. This study employed finite elements software (PLAXIS 3D) evaluate seepage force developed around sub-river segment during different construction stages and for other water levels Tigris. found that when level changes from ...

Tigris River is an environment of shallow waters because its low depth and it has been identified as a multi-path channel. The underwater propagation leads to reverberation well fading, which causes large transmission loss. present paper conducts 3 acoustic simulation outcomes in the district Abu Dali - Kazem Al Ali village beaches Baghdad Iraq. distance from sender receiver are (100m, 1000 m, ...
