in this study, application ofweap model (soil moisture method) have been investigated for simulating hydrological behavior in ahar-chai basin. according to the development of pressurized irrigation systems in this basin, since 2005, two models were carried out for two periods, pre-pressurized period (1998-2006) and pressurized period (2006-2013). irrigation method in first model was surface irr...

Tracer gas studies and oxygen uptake measurements have shown that pressurized gas transport improves oxygen supply to roots in the wetland tree species Taxodium distichum L. Rich. (Taxodiaceae), Betula pubescens J.F. Ehrh. (Betulaceae), and Populus tremula L. (Salicaceae), but not in Acer pseudoplatanus L. and Ilex aquifolium L., which are found in drier habitats. In the deciduous tree species ...

In this study was examined the factors affecting the unwillingness to adopt pressurized irrigation methods among farmers' groups (with different levels of drought) in Ardabil province (Iran). Mixed method (Qualitative – Quantitative paradigm) was used for doing this research. First, by drought zoning of Ardabil province (by SPI method and GIS), three regions included the mild, moderate and seve...

SUMMARY The Sarria-Triacastela-Becerreá seismicity is located in an intraplate region considered seismically stable, but 1995 started unprecedented earthquake activity the area. Since then anomalous long-term continuous remains until now same location. Despite and large magnitudes for standards (5.1 Mw), origin mechanisms of this unclear. isolation background from main shock–aftershock contribu...

This study compared Ojeok-san (Wuji-san in Chinese) decoctions produced using different extraction methods for variable times. Decoctions were extracted in pressurized or non-pressurized conditions for 60, 120, and 180 mins. We investigated the Ojeok-san extract yield, the total soluble solid content, the hydrogen ion concentration (pH), and the reference compound content. The extract yield and...

Antarctic ice streams are associated with pressurized subglacial meltwater but the role this water plays in the dynamics of the streams is not known. To address this, we present a model of subglacial water flow below ice sheets, and particularly below ice streams. The base-level flow is fed by subglacial melting and is presumed to take the form of a rough-bedded film, in which the ice is suppor...
