Application of the reliability assessment results for pumping stations’s modernization [PDF]
E3S Web of Conferences, 2023 Work on the modernization of irrigation pumping stations in our Republic has a great relevance. Technical modernization and reconstruction of pumping stations require a reliable scientifically based methodological approach. Each pumping station regularly

Software for Evaluating Pumping Tests on Real Wells
Applied Sciences, 2021 As the climate is changing, greater exploitation of groundwater reserves is becoming evident; however, this would have been apparent even without climate change. Therefore, increasing emphasis is given to maintaining well functionality.

Technical note: Analytical drawdown solution for steady-state pumping tests in two-dimensional isotropic heterogeneous aquifers [PDF]
Hydrology and Earth System Sciences, 2016 A new method is presented which allows interpreting steady-state pumping tests in heterogeneous isotropic transmissivity fields. In contrast to mean uniform flow, pumping test drawdowns in heterogeneous media cannot be described by a single effective or ...

Geophysical Journal International, 2006 SUMMARY We performed pumping tests with a periodic succession of injection and production intervals in a field of three shallow boreholes penetrating a jointed sandstone formation. Tests were conducted at periods ranging from 10 to 5400 s and pumping rates between 5 and 20 l min−1.

Toward coupling of groundwater drawdown and pumping time in a constant discharge
Applied Water Science, 2022 Groundwater is considered an essential water resource in arid and semi-arid regions such as Iran. This study used a copula-based approach to analyze the joint frequency of groundwater level and the duration of groundwater pumping with a constant ...
