The interaction of feeding by a grass bug, Ir"bisia pacifica (Uhler), and drought stress on growth of Great Basin wildrye, Leymus cinereus (Scrih. & Merr.) Love, and intermediate wheatgrass, Thinopyrum intermedium (Host) Barkw. & D. R. Dewey, was studied in the greenhouse. At peak production, control plants of Great Basin wildrye had more than twice as much green leaf area per tiller than bug-i...

Meteorological droughts like those in summer 2003 or spring 2011 in Europe are expected to become more frequent in the future. Although the spatial extent of these drought events was large, not all regions were affected in the same way. Many catchments reacted strongly to the meteorological droughts showing low levels of streamflow and groundwater, while others hardly reacted. Also, the extent ...

Drought is a phenomenon caused by environmental and climatic changes. This phenomenon is affected by shortage of rainfall and temperature. Dust is one of important environmental problems caused by climate change and drought. With recent multi-year drought, many environmental crises caused by dust in Iran and Middle East. Dust in the vast areas of the provinces occurs with high frequency. By dus...

Inter-annual variability of hydro-meteorological variables indirectly influence soil moisture conditions in winter and early spring seasons. The interactions between temperature changes drought are studied by an application statistical analyses minimum (Tmin), consecutive days with exceeding the 0 °C threshold value, number melting pulses season Standardized Evaporation Precipitation Index (SPE...

The issue of mitigating the expected effects drought has become quite prominent within scope planning, development, and management water resources affected negatively by climate change. An integrated approach must be planned primarily for sustainable management. To conduct risk analyses, a sufficient amount data available. historical process basin known, there plan that is assessed with several...

The variations in summer precipitation according to different grades and their effects on drought/flooding the Haihe River basin were analyzed using daily data from 161 meteorological stations 1972 2021. results showed that number of rainy days (NRD) significantly declined past 50 years, mainly due reduction light-rain days. amount (PA) exhibited prominent interdecadal characteristics, showing ...

Abstract. Monitoring drought and mastering the laws of propagation are basis for regional prevention resistance. Multivariate indicators considering meteorological, agricultural hydrological information may fully describe conditions. However, series variables in cold arid regions that too short or missing make it difficult to monitor drought. This paper proposed a method combining Soil Water As...
