Step-drawdown tests and the Forchheimer equation [PDF]
Water Resources Research, 2010 Step‐drawdown tests (SDTs) typically involve pumping a well at a constant rate until a quasi‐steady state (QSS) is observed in the drawdown response. The well is then pumped at a higher constant rate until a new QSS is achieved. The process is repeated for additional flow rates.

FABM-NflexPD 1.0: assessing an instantaneous acclimation approach for modeling phytoplankton growth [PDF]
Geoscientific Model Development, 2021 Coupled physical–biogeochemical models can generally reproduce large-scale patterns of primary production and biogeochemistry, but they often underestimate observed variability and gradients.

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 ...

Freshwater-salt water interface dynamics during pumping tests
Acque Sotterranee, 2019 Freshwater-salt water interface (FSI) location is very important information for decision maker in managing coastal aquifer system, however, its temporal change have been hard to get using conventional method such as EC monitoring at one or several fixed

Step-drawdown tests: linear and nonlinear head loss components
Hydrogeology Journal, 2022 AbstractCoefficients B and C of the Jacob (1947) equation, usually derived from step-drawdown tests, are commonly attributed to “aquifer losses” and “well losses”, respectively. This paper analyzes and separates the linear laminar, nonlinear laminar and turbulent losses occurring during flow from an aquifer to a screened well. From this, one can derive
