In systems and control theory dynamical systems described by partial differential equations are known as distributed parameter systems. For modelling and dynamical analysis of distributed parameter systems wide possibilities are offered by virtual software environments as ANSYS, COMSOL Multiphysics, ProCAST, MODFLOW, based on numerical solution of sets of partial differential equations by finit...

A key aspect of estimating transmissivity distributions from pumping tests is the spatial resolution of the estimation. Some assumption of spatial structure is needed to make an inversion possible. Both the nature of groundwater flow and assumed structure cause a smeared estimate. This research is focused on the how information content of the data smears the estimate. The inversion procedure ne...

During tunnel construction in strongly developed karst terrain, water inrush hazards often occur due to the complex hydrogeological conditions, which require accurate prediction of inflow. In this study, a dynamic modeling approach for inflow tunnels using conduit flow process (CFP) is that considers both duality and changing boundary conditions tunnel. The CFP model has good agreement with fie...

Exercise 3.2d: Calculate weights on hydraulic-head and flow observations For the head observations, first calculate the total variance of measurement error for the head observations, by adding the variance for the elevation measurement and the variance for the water-level measurement. This total variance is 1.0025 m, as shown in Table 3.2. Then, calculate the weight as the inverse of this varia...
