Analysing Effects on Ground Water Levels Due to Conversion of Rural to Urban Landscapes
Journal of Landscape Ecology, 2022 Greater NOIDA evolved from 1991 with 101 villages to 2020 with 293 villages. This is an ideal case of rural to urban transformation in the immediate past. This transformation led to a decrease in recharging natural surfaces and an increase in impermeable

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.

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

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

Hydrology, 2017 We assess the errors produced by considering temperature as a conservative tracer in fluviokarst studies. Heat transfer that occurs between karstic Conduit System (CS) and Porous Fractured Matrix (PFM) is the reason why one should be careful in making ...

Determination of Turbulence Coefficient using Genetic Algorithms [PDF]
Mehran University Research Journal of Engineering and Technology, 2012 An effort has been made to optimally determine the status of turbulence loss coefficient in the present study. The parameter is identified in the framework of GA (Genetic Algorithm), which consequently resulted in the development of a computer model ...
