AQUIFER TESTS – Estimation of T, K and S for an aquifer CONFINED AQUIFER Graphical solutions to flow equations: Theis type curve method, (Cooper) Jacob time drawdown and distance drawdown methods Introduction: - Previous emphasis: Predicting drawdown based on known aquifer parameters. Examples: - You get a call from a client, they want to know why their well went dry - You need to design a de-watering project - You need to predict drawdown from multiple wells or aquifers with hydraulic boundaries - Now: We will look at another aspect of flow to wells: making estimates of aquifer parameters (T, K, S) based
