BACKGROUND: Fertilizer management plays an important role for obtaining satisfactory yields and to increase crop productivity. Improve saving water in irrigated agriculture and thereby improving water use efficiency is of paramount importance in water-scarce regions. OBJECTIVES: This study was conducted to assessment effect of different levels of irrigation re...

We have observed the impingement of two cylindrical liquid jets of either the same liquid, water, or two mutually immiscible liquids, water and methylcyclohexane (MCH), in either air under normal pressure (0.101MPa) or nitrogen gas under elevated pressures up to 4.0MPa. The flow rates of the two jets were adjusted such that they had equal axial momentum. Irrespective of the system pressure, we ...

The book presents the data from a study of water-physical properties and moisture content red soils Kolchic forest, as well tea citrus plantations in Ajara, gives an assessment plants’ productive supply. It demonstrates significant loss of precipitations retained by forest crown mandarin plantations, high irrigation efficiency tangerine improving harvest yield fruit quality. This will be u...

Runoff and sediment loads have exhibited significant changes over the past six decades in the Yellow River Basin, China. The current study evaluates the changing trends and regime shifts in runoff and sediment loads at both the annual and monthly time scales. The associated spatial and temporal variations are analyzed by a sequential t-test analysis of the regime shifts (STARS) approach and the...

ion and impoundments. It is widely acknowledged that alterations to flow regime impact on riverine ecosystems. As a result, hydromorphology, which includes the hydrological regime, is embedded within the WFD as a supporting element to achieve good ecological status (GES). Environmental flow releases from impoundments such as reservoir dams will need to be implemented to mitigate impacts from th...
