Fig.1 Sketch map of Dongting Lake Water System
For 50 years, conditioned by natural factors as river channel sedimentation and less precipitation, as well influences from engineering constructions as channel straightening of Jingjiang River and Gezhouba Hydro Project, and in particular, water storage and operation of Three Gorges Project, flow and sediment diversion at Four Inlets of Dongting Lake are decreasing and the zero flow period at Four Inlets river course is constantly prolonged.
Since the 1950s, engineering constructions as channel straightening of Jingjiang River, Gezhouba Hydro Project, and Three Gorges Project have vital influence to variations of flow and sediment diversion at Three Inlets of Jingjiang River.
Conclusions Conditioned by natural factors and influenced by engineering construction, flow and sediment diversion at Four Inlets of Dongting Lake continues to decrease, zero-flow period continues to prolong, the Four Inlets river courses and Dongting Lake continues to shrink, and water resources problems in the Dongting Lake area continues to deteriorate.

Introduction
A wide class of material science problems and engineering applications rely on enhancing surface properties of various engineering components.
To illustrate the progress and advance in this area, some recent examples of stress measurements, made using KOWARI stress diffractometer with high spatial resolution of ~0.2 mm, are reported.

The choice made is also not
unique and highly dependent on engineering experience and existing pre- knowledge.
However, due to the variety of the modelling assumptions, the test data uncertainties, the parameter sets and the control parameters of the numerical procedures a robust black box procedure to be applied without engineering experience can presently not be expected.

Introduction
The status of composite material in engineering applications is in continually increasing these years.
Fiber matrix combinations are employed in the automotive and aircraft industries, for the construction of space structures, in civil engineering structures like footbridges….
Christensen [2] and Gibson [3] for examples present the constitutive relations for different types of anisotropy based on engineering constants.
