This handbook systematically presents analytical solutions for groundwater flow during aquifer tests, integrating a comprehensive range of known solutions from well hydraulics and subsurface flow theory, spanning from early 20th-century work to recent scientific publications. It features approximately 300 transient solutions applicable to various aquifer test scenarios and hydrogeological conditions, all rigorously tested and implemented in the ANSDIMAT software. Divided into three parts with appendices, the first section addresses basic analytical relationships for pumping tests with constant discharge rates, covering conceptual models for confined, unconfined, and multi-layer aquifers, as well as factors like flow boundaries, aquifer anisotropy, and wellbore storage. The second part delves into complex pumping test settings and well configurations, presenting analytical solutions for horizontal or inclined wells, constant-head tests, and multi-well variable-discharge tests, along with detailed descriptions of slug and recovery tests. The final section includes algorithms for evaluating hydraulic characteristics through analytical and graphical methods, supplemented by the ANSDIMAT tool, which addresses practical engineering-hydrogeological problems. Appendices provide hydrogeologists with extensive mathematical descriptions, plots, and approximations of analytical functions. This resource is invaluable for hydrogeologist
