Transfer function approach of solute transport in unsaturated homogeneous soil under unsteady flow condition;

Numerical method for unsteady flow in lock manifold;

Moreover, there are some unsteady factors occur in practical tub flowing, In article, the change of phase state and unsteady flow factor in flow process are considered, the mathematical model is established.

Transfer function model for simulating nitrate leaching in soil from applied and indigenous nitrate in transient flow Ⅰ.lysimeter test;

le frictional term in the computation of unstable flow,and unreasonable results are obtained for the shallow and wide river.

Even in the Lugeons packer permeability test,a test of non-stationary flow is still useful.

The mathematic model of non-stationary flow with constant discharge is introduced and used in the test.

Numerical analysis of 3-D unsteady seepage through fracture network in rock mass;

Analysis on simplified calculation conditions for unsteady seepage wetting front locations in earth dams based on finite element method;

Empirical formulas for important parameters of unsteady seepage of levees;

In this study,a digital image based(DIB) numerical method is proposed for the two-dimensional transient seepage analysis of the fractured rock masses by actually taking the spatial distribution of main fractures,minor fractures and intact rock into account.
