Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -AEM is an important addition to ground water modeling technique based on superposition of analytic elements. This method employs superposition of analytic functions to create an approximate solution to the ground-water flow problem. In AEM each of analytic element represents different flow feature of the aquifer. AEM model is applied to calculate groundwater head for homogeneous and heterogeneous steady flow condition for synthetic problems. Results are validated with available analytical solution and finite element method. Sensitivity analysis is carried out by varying parameter of aquifer and amount of discretisation of element. Later AEM model is also applied for unsteady well drawdown problem. The radial collector well comprises of horizontally placed screen pipes or laterals in riverbed aquifer. The complete structure behaves like a well with large effective radius. Radial collector wells offer a feasible and sustainable pumping arrangement to augment induced recharge. The use of radial collector well structures has been growing in various parts of the world. Simulation of a synthetic RC well by FEM is covered in the book. 184 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Utilisation of groundwater is steadily growing in many parts of the world to cope up with the increasing demand in various water user sectors. However scientific use of the precious groundwater calls for proper planning which involve modeling of the system. Recently for groundwater system planning and management use of soft computing tools is growing since these are found better than conventional numerical optimisation technique. Since groundwater problems involve non-linear objective function, their gradient with respect to parameters cause numerical instability. Simulated annealing, artificial neural network and genetic algorithms help in assessment of near global optimal solutions which are meaningful for real system simulation. Synthetic aquifer problems considered in the presented book are particularly useful to demonstrate the application of SA, ANN and GA to assess the aquifer system parameters. However when properly understood from the given applications these can be meaningfully applied to real problems. 372 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Particle swarm optimization is an upcoming evolutionary algorithm used extensively in water resources engineering. In groundwater hydrology in this book it is used to optimize cost of installing pumping wells to meet the groundwater demand in agriculture, municipal and industrial sectors. Its variants are also applied for optimal cost comparisons. Differential evolution is relatively more recent evolutionary meta-heuristic which is suitable for non-linear, non-differential discrete objective functions. Constraints are incorporated by penalty function. Inverse modeling is essential for aquifer system parameter estimation. Transmissivity, aquifer recharge and storage coefficient are assessed for a confined aquifer by DE. Problems in both sections require simulation-optimization modeling where aquifer system simulation engages finite element technique which is covered in the book apart from details of PSO and DE optimizers. 300 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A simulation-optimization model which incorporates the flow and contaminant transport simulation model within an optimization program helps in designing the best satisfactory bioremediation system. For the effective bioremediation system design, the groundwater flow and contaminant transport should be simulated at various time steps. For optimal design, groundwater flow and transport modelling is coupled with optimization techniques of Particle swarm optimization. Biodegradation process is simulated by incorporating an instantaneous reaction model. Decision-makers require adequate information on these interactions in order to formulate sustainable water resources development strategies. A successful groundwater management requires precise information on groundwater quantity and quality, its renewability and the hydrogeological structure of the subsurface formation. Differential evolution (DE) is a method that optimizes a problem by iteratively trying to improve a candidate solution with regard to a given measure of quality. In this book in 2nd section transmissivity (T) values are estimated by coupling the differential evolution optimization technique with FEM simulation model. 344 pp. Englisch.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Agricultural, industrial, municipal, navigational, and recreational demand of water is met by two major sources surface water and groundwater. Compared to surface water sources which depend upon the annual rainfall and the melting of ice and snow, ground water supply is more reliable because it does not directly depend on the annual rainfall. Therefore utilization of groundwater resources is growing over the years. However unplanned use of groundwater has caused several problems in many places. Groundwater modeling is used as a major tool to understand the complex dynamic behaviour of aquifer system. This required aquifer system parameters which are very difficult to evaluate by field methods alone. Inverse modeling helps in adequate assessment of these parameters. These aspects for certain specific cases are dealt in the book involving modeling and inverse modeling in groundwater hydrology.…
