Development of foliage biomass of young spruce and beech stands in the mountain water balance research area
Norway spruce European beech young stand
2015/3/16
The investigation of foliage biomass development including LAI and the growth of spruce and beech stands in the juvenile stage (age 1 to 21 years) represents a special complementary study to long-term...
Impact of Arable Land to Grassland Conversion on the Vegetation-period Water Balance of a Small Agricultural Catchment (Němčicky Stream)
hydrological extremes hydrological modelling land use change water balance
2015/3/2
This paper presents results of decadal (10-day) water balance simulations for the vegetation periods (April to October) of 2001 (normal year), 2002 (wet year) and 2003 (dry year) in the Němčicky ...
Quantitative Analysis of Groundwater Effluent and Reservoir-Water Influent in a Small Pond Using 222Rn- and Water-Balance Equations
stagnant film dispersion
2009/9/10
Percolation of water from a pond may cause a landslide in a hilled rural area. Before measures to prevent such landslides can be planned, it is essential to identify reservoir-water influent from the ...
Contemporary Role of Catchment Water Balance Data for Forest Evapotranspiration Research
catchment water balance evapotranspiration flux measurements sap flux measurements water cycle water yield
2009/8/27
Recently, catchment water balance measurements have not been used actively for examining forest evapotranspiration compared to process-based measurements based on meteorological and sap-flow methods. ...
Diurnal Change in Water Balance of Heat-Tolerant Snap Bean (Phaseolus vulgaris) Cultivar and Its Association with Growth under High Temperature
Heat tolerance Phaseolus vulgaris Sap flow Transpiration
2009/7/24
A snap bean (Phaseolus vulgaris L.) cultivar Haibushi shows high productivity under high-temperature conditions. Together with intensive radiation, high temperature enhances transpiration and causes w...
Effects of Soil Clay Content on Water Balance and Productivity in Rainfed Lowland Rice Ecosystem in Northeast Thailand
Oryza sativa Paddy Percolation Seepage Water table
2009/7/23
Water availability is one of the determinants of productivity of rainfed lowland rice (Oryza sativa L.). Quantifying water losses from a paddy field, such as deep percolation and lateral seepage, assi...
Comparison of daily evapotranspiration rates obtained from water balance model and modified Bowen`s ratio method
evapotranspiration modelling Bowen`s ratio method
2008/11/21
The processes of energy and water exchange between the earth surface and atmosphere have a very significant influence on the microclimatic conditions and consequently, on plant production. Evapotransp...
Effect of waxing on the water balance and keeping qualities of cut anthuriums
anthuriums waxing transpiration shelf-life
2008/11/19
Improving the shelf life of cut anthuriums through the application of a fruit wax was investigated. The transpiration rate of cut flowers held under ambient (28°C, rh 60�80%) and refrigerated c...
