Then, every subentry of water balance is modeled in this region by SWAT from the year 1988 to 2001, the model is well calibrated and the results fit the reguest of water budget.
For a tenyear period ended 1980, the averaged relative error between the model estimates and the water budget estimates is 4.1% and the standard error of the relative errors for the 51 watersheds or regions is 3.0%.
The law of water requirement of some crops and different planting mode in Linze's oasis on the Heihe River middle valley was studied by water equilibrium method through preventing seepage sump, that was built with soil engineering plastic film, and its volume was 2 m×2 m×2 m.
They are of practical significance to the studyof water movements in soil and of consumption in evapouration, to the calculation of water equilibrium of soil, and analysis of intake supply.
The water consumption of cotton on Linze County in the Hexi Corridor Region was studied by water equilibrium method. The water consumption is 675. 5mm. 5 or 6 times of irrigation should be applied for promoting water use efficiency.
Equation of water quantity balance which is taken as basis for water level control model has feature of good imitative and interactive as well asfast calculation therefore, it is suitable for real time control and for experts to apply his experience.
For reasonable determination of the sequence, method, and optimum scheme for closure works, a study is performed on the regularity of variation of hydraulic factors at the entrance of sea reclamation works based on the water quantity balance equation.
LUCC changes the surface evaporation, soil moisture and intercept of land cover, affects the original term of the surface runoff, to influence the hydrological process of the basin directly, the accumulative changes influence water quantity balance.
The main calculating methods are composed of the exchanging water cyclemethod,minimum water level method,water quantity balance method and ecological functionsmethod, especially the last one is the most popular.
These evidences suggested that both Hg2+-sensitive aquaporins and ion channels existing in the protoplasm and vacuole membranes could regulate root water uptake, transport, and integral plant water balance.
In addition, both marten and sable featured much higher rate of evaporation loss in the overall water balance and, consequently, a higher quantity of heat dissipated with evaporation as compared to polecat.
The mechanism incorporates the effect exerted on the dynamics of the water budget of the Caspian Sea by the nonlinear dependence of the evaporation rate on the moistening of the basin.
The stochastic differential equations describing the water budget of the sea basin and the sea proper and the respective solutions of the Fokker-Planck-Kolmogorov equation are shown to have stationary bimodal density of the level probability.
The critical equilibrium humidity of the mites marks the relative humidity of the ambient air at which sorption and transpiration counterbalance each other and at which the mites are capable of maintaining body water equilibrium.
These findings indicate that the turgor pressure primarily determines the corresponding pressure in the vessels (and vice versa) due to the tight hydraulic connection and thus due to the water equilibrium between both compartments.
Calibrating on the basis of the Northern hemisphere bomb test data yields a model which has approximately twice the CO2 ocean uptake of the one-dimension box diffusion models calibrated on the basis of deep water equilibrium carbon 14.
