Thus, Thiem's equilibrium equation can be rewritten as
We then have Thiem's equilibrium equation rewritten as:
Thus, Thiem's equilibrium equation is
That is to say, when the draw- down curve does not expand any more, the pumping time coming to t and the influence range extending totf , Jacob's modified nonequilibrium equation will be identical to Thiem's equilibrium equation.
Thiem's equilibrium equation),the coefficientofpermeability (k) is the only required hydraulic parameter.
