  hydrological system
A synthesis of the hydrogeological investigations carried out in an important karst region of the Jura Mountains led to the recognition of a major hydrological system: the Aubonne-Toleure-Malagne system.
      
The main directions in global warming and its possible impact on the hydrological system are determined.
      
Each basin cell is characterized by its geological, pedological and morphological status, and may be considered a unitary hydrological system, linked to the others by geomorphological and hydraulic relationships.
      
The results indicated that the hydrological system has been altered since the 1970s, increasing flood peaks by 1.5-2.5 times and shortening peak appearance by 7?hours.
      
Variation in the hydrological system was expressed as a basis of delineating the three components and estimating their functions.

This paper studies the identifiability problem of hydrological system modeling, taking the implicit rainfall-runoff model as a target for study. Because most implicit models and object functions are very difficult to obtain analytical solution or to solve high-order derivatives, a numerical analysis method is developed, which not only can assess the identifiability but also can provide useful information for dealing with the parameter optimization. It has been verified by a number of experiments and practical...

In estuarine area, not only the input, but also the output of a hydrological system is often more than one, so the system is often a multiinput and multioutput system. In the same time, the hydrological phenomena are affected both runoff and tidal current. Considering the characteristics, this paper gave a mathematical model and an identification method——the correlative identification method. Using the observed data from the Pearl River Delta for verification, the verifying results are...

In estuarine area, not only the input, but also the output of a hydrological system is often more than one, so the system is often a multiinput and multioutput system. In the same time, the hydrological phenomena are affected both runoff and tidal current. Considering the characteristics, this paper gave a mathematical model and an identification method——the correlative identification method. Using the observed data from the Pearl River Delta for verification, the verifying results are good.
