The method for constructing the stochastic model based on regression and spectral analysis

Autor: V. I. Shveikina, I. A. Kozhevnikova

Publikováno v: Water Resources. 42:594-606

The article gives a procedure for constructing a stochastic model, whose efficiency was verified on hydrological data. The procedure includes the construction of regression relationships between the examined variable and its increment, the removal of

Modeling level variations in Lake Kineret

Autor: V. I. Shveikina, I. A. Kozhevnikova

Publikováno v: Water Resources. 41:627-633

An autonomous differential equation with a random perturbing force is used as a model of level variations in Lake Kineret. The simulated trajectory, derived from this equation, qualitatively reflects the specific features of level variations in Lake

The Shewhart-Deming Control Charts for Water Use Management

Autor: V I Shveikina, O M Rozental

Publikováno v: Water sector of Russia: problems, technologies, management. :102-115

Proper management of water use is possible only provided that the processes occurring in water and determining variability of the indicators to be controlled are statistically stable. Therefore, observation of the processes’ stability/instability i

Nonlinear dynamics of level variations in the Caspian Sea

Autor: I. A. Kozhevnikova, V. I. Shveikina

Publikováno v: Water Resources. 35:297-304

Caspian Sea level variations, which have several equilibrium states, are studied by the methods of the theory of nonlinear dynamic systems. Normal monthly values of sea level according to data collected at Makhachkala gauge from 1900 to 2000 are cons

Estimating the probabilities of Caspian level transition from one state into another based on the solution of Kolmogorov’s inverse equation

Autor: I. A. Kozhevnikova, V. I. Shveikina

Publikováno v: Water Resources. 35:43-50

Variations in Caspian Sea level are examined by using its water balance equation. Two important problems of modern hydrology are solved. The first problem consists in determining the transition probabilities from a fixed sea level to its upper (lower

Autor: V. I. Shveikina, V. I. Naidenov

Publikováno v: Water Resources. 29:160-167

A new thermophysical mechanism of the Caspian Sea level variations is proposed. 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
