--> Gives Fast Results

Theis Made Easy provides theory and application for new and improved methods that can be used to solve for transmissivity and the storage coefficient using pump test data and the Theis equation - without the Theis curve! Methods are provided that use pump test, recovery, and specific capacity data. Promising new methods that solve for the storage coefficient using observation well recovery data are also included. Full page illustrations and easy to read tables are utilized to greatly reduce the learning curve. The Theis Without Graphs computer program is also provided, along with many data sets that can be used to test these methods. The program also provides a step-drawdown solution and the ability to model a pump test. Theis Without Graphs is easy to use! It has been tested by hydrogeology students and engineers, and provides an extensive output.

--> The book and computer program are both user friendly.
--> Theis time-drawdown can be solved without the Theis curve, but this is "no black box". The Theis assumptions can be verified without curve matching.
--> Theis distance-drawdown can be easily solved using 3-sets of drawdowns.
--> Storativity can be solved with a recovery method that uses residual drawdown data from observation wells.
--> Specific capacity solutions can be adjusted for well efficiency, dewatering, and partial penetration.
--> The transient limit of the cone of depression is calculated.
--> A step-drawdown solution is provided.
--> A pump test can be modeled.
--> Many data sets are provided, including a pump test project.

An extensive, easy to read Z(µ), µ, W(µ), and µ W(µ) table is also included. ISBN - 0-918334-85-3. Publ. 1994 WRP.

Here's what professional ground-water scientists are saying about Dr. Kasenow's research:

"He possesses a wonderfully articulate yet pragmatic method of conveying his thoughts, intuitions and application of theory. His work stands the test of time." --- Walter J. Bolt, Senior Project Manager, PM Environmental, Inc.

"Dr. Kasenow has shown both his creativity and drive to build on, rather than simply follow techniques developed by others. His books present relatively complex concepts in easy to understand graphic form without oversimplification." --- Dana R. Unangst, Project Manager, Insight Environmental Services, Inc.

"It is refreshing to see someone looking at alternatives to complicated and sometimes subjective curve matching techniques." --- Scott R. Green, Senior Hydrogeologist, Conestoga-Rovers & Associates.

"As President of a consulting firm, I am always concerned with balancing costs and providing clients with complete and thorough data evaluations. Dr. Kasenow's practical application techniques have allowed my firm to complete thorough data evaluations at lower costs. Once one uses Dr. Kasenow's data evaluation programs, you are left with the feeling of 'why did I waste my time with other programs?" --- Mark. B. Sweatman, CPG, President, Insight Environmental Services, Inc.
