Agricultural land drainage is an instrument for growing production and a tool the conservation of resources. The performance systems thus critical achieving sustainable agricultural Recently, many types software have been developed in this field modeling simulating these systems. SISDRENA simulation model underground main objectives paper are to simulate different combination depths spaces betw...

Forest tree canopies have a critical influence on water cycles through the interception of precipitation. Nevertheless, radial patterns canopy may vary interspecifically. We analyzed using catchments along transects underneath four common forest species (Acer macrophyllum, Alnus rubra, Pseudotsuga menziesii, and Thuja plicata) in Pacific Northwest over two years. Near center leaf-off season, wa...

Dryland plant ecosystems tend to exhibit bistable dynamics with two preferential configurations of bare and vegetated soils. Climate fluctuations are usually believed to act as a source of disturbance on these ecosystems and to reduce their stability and resilience. In contrast, this work shows that random interannual fluctuations of precipitation may lead to the emergence of an intermediate st...

To evaluate the effect of water-deficit stress on the yield, antioxidant activity, and physiological traits of four Iranian melon genotypes (“Khatooni,” “Suski-Sabz,” “Zarde-Tabriz,” and “Shiari”), an experiment was conducted. The irrigation levels were: (1) control (100%ETc); (2) deficit irrigation 66% (66%ETc); and (3) deficit irrigation 33% (33%ETc). The results showed that the yield and rel...

Excessive water and deficit are two important factors that limit agricultural development worldwide. However, the impact of waterlogging on winter wheat yield a large scale, compared with drought caused by deficit, remains unclear. In this study, we assessed damage to using downscaled fused TRMM 3B42 from 1998 2014. First, area-to-point kriging (APK) it rain gauge measurements geographically we...

The presented study concerns the delayed response of photosynthetic performance to summer drought. Increasing drought events are thought be one most detrimental and expensive natural disasters. For that reason, we studied condition urban trees, which especially susceptible water deficit. Three species linden trees (T. tomentosa, T. × europaea cordata) growing in city area Krakow, Poland, were i...

Global warming intensifies the hydrological cycle by altering rate of water fluxes to and from terrestrial surface, resulting in an increase extreme precipitation events longer dry spells. Prior intensification work has largely focused on without joint consideration evaporative demand changes how plants respond these changes. Informed state-of-the-art climate models, we examine projected its ro...

Water shortage is one bottleneck that limits economic and social developments in arid semi-arid areas. As the impacts of climate change human disturbance intensify across time, uncertainties both water resource supplies demands increase Taking a typical region China, Xinjiang Uygur Autonomous Region, as an example, yield depth (WYD) utilization (WUD) from 2002 to 2018 were simulated using Integ...

Abstract Most socio-economic activities in Africa depend on the continent’s river basins, but effectively managing drought risks over basins response to climate change remains a big challenge. While studies have shown that stratospheric aerosol injection (SAI) intervention could mitigate temperature-related impacts Africa, there is dearth of information how SAI influence characteristics and ris...

Abstract. Since the beginning of this century, Europe has been experiencing severe drought events (2003, 2007, 2010, 2018 and 2019) which have had adverse impacts on various sectors, such as agriculture, forestry, water management, health ecosystems. During last few decades, projections impact climate change hydroclimatic extremes often used for quantification changes in characteristics these e...
