Issued without a dust jacket. -- This technical volume presents a specialised numerical framework for identifying hydraulic parameters in layered aquifer systems. Deviating from traditional analytical "type-curve" methods, Lebbe introduces a generalised interpretation method based on the MLU (Multi-Layer Unsteady state) computer program. The methodology treats the subsurface as a complex sandwich of aquifers and aquitards, allowing for the simultaneous processing of drawdown data from multiple pumping and observation wells located in different stratigraphic horizons. The core of the work is the application of the Levenberg-Marquardt nonlinear regression algorithm to minimise the residuals between observed and calculated drawdowns. A distinguishing feature of Lebbe's approach is the rigorous use of sensitivity analysis and correlation matrices to address the non-uniqueness of parameters. By analysing the "identifiability" of hydraulic constants, the text demonstrates how to distinguish between different hydrogeological models and quantify the reliability of estimated values for transmissivity, vertical flow resistance (leakage), and storage coefficients. The book provides practical guidance on interpreting constant-rate, step-drawdown, and recovery tests within leaky, confined, or unconfined systems. It remains a foundational text for hydrogeologists specialising in inverse modelling and is essential for those using numerical codes to characterise heterogeneous, multi-layered groundwater reservoirs.

Taschenbuch. Condición: Neu. Druck auf Anfrage Neuware - Printed after ordering - Hydraulic parameter identification is a crucial step in hydrogeological investigations. The book proposes a unique and generalized interpretation method for single and multiple pumping tests made in groundwater reservoirs with layered heterogeneity and with or without lateral anisotropy. This method eliminates the drawbacks of the numerous and frequently applied interpretation methods. The book also presents an introduction to inverse modeling, resulting in optimal parameter values with their joint confidence region and the corresponding residuals. Cross sections through this multidimensional region elucidate the relation between the shape of this region and some statistical parameters describing the reliability of the identified parameters. This method is demonstrated by means of five pumping or recharge tests.
