This paper presents a functional formulation of the groundwater flow inverse problem that is sufficiently general to accommodate most commonly used algorithms. Unknown hydrogeological properties are assumed be spatial functions can represented in terms (possibly infinite) basis function expansion with random coefficients. The unknown parameter related measurements for estimation by “forward operator” which describes measurement process. In particular case considered here, interest...
Digital Twins (DTs) are on the rise as innovative, powerful technologies to harness power of digitalisation in WRRF sector. The lack consensus and understanding when it comes definition, perceived benefits technological needs DTs is hampering their widespread development application. Transitioning from traditional modelling practice into DT applications raises a number important questions: When model's predictive acceptable for DT? Which frameworks most suited applications? data structures...
Finite difference and finite element methods are frequently used to study aquifer flow; however, additional analysis is required when model parameters, hence predicted heads uncertain. Computational algorithms presented for steady transient models in which storage coefficients, transmissivities, distributed inputs, boundary values may all be simultaneously Innovative aspects of these include a new form generalized condition; concise discrete derivation the adjoint problem with variable time...
Steady flow regimes for three‐dimensional lake‐aquifer systems are studied via idealized mathematical models that extensions of earlier simplified vertical section interaction between shallow lakes and underlying aquifers. The present apply to a circular lake at the surface rectangular aquifer finite depth, yielding truly representation resulting system. Flux boundary conditions applied ends aquifer, with net recharge or evapotranspiration water table. is defined by region constant head. By...
A numerical model is used to examine groundwater flow in vertical section near surface water bodies, such as lakes, wetlands, ponds, rivers, canals, and drainage irrigation channels. Solutions are generated partly by superposition achieve computational efficiency. large number of regimes identified, with their characteristics controlled regional table gradients, recharge the aquifer, body length, aquifer anisotropy, hydraulic resistance bottom sediments. Different distinguished presence...
Interaction between surface water and groundwater depends on the position of a lake within regional flow system. The approach in this paper is to nest local‐scale two‐dimensional (2‐D) aquifer model 1‐D examine effect setting water–groundwater interaction. This extends previous steady state modeling, which presented earlier publications. results indicate that type impose constraints near field geometry. Only nine 39 previously identified regimes are possible system considered. Flow‐through...

Steady seepage through a levee or dam separating reservoirs with different levels and densities is shown to result in five possible flow configurations. If are equal, the problem reduces classical of dam. lower reservoir less dense, stationary wedge may not form inside near downgradient level. more forms toe levee, as saltwater intrusion. Another possibility that dense can connect two reservoirs, thus allowing bidirectional flow. Conditions derived which define when these configurations...
An existing algebraic solution to Laplace’s equation for the steady three-dimensional temperature distribution around an ellipsoid embedded in a uniform, isotropic medium is used study characteristics of porous/permeable media flow near variety objects. Symbolic-computation techniques are derive new closed-form expressions potentials general ellipsoids. These simple results various degenerate and limiting cases. Flow paths calculated using numerical particle-tracking techniques, defining...
