| Abstract | The problems identified in Sukhothai Groundwater Development Project (Zonel) are the water distribution problems resulting in decreased irrigation efficiency and cropping intensity. Seeking to address these problems, this study demonstrates the use of raster-based Geographical Information Systems (GIS) for the planning and management of groundwater. Permeability, storage coefficient, water abstraction and initial depth to the water table which are affecting the groundwater fluctuation were selected for the preparation of input coverage. The spatial distributions of permeability and storage coefficient were determined for the entire study area from the collected scattered samples by using the kriging method. Maps of each permeability and storage coefficient input parameters were generated by integration of kriging with GIS. A linear combination model was used correlate the water level change with the permeability, storage coefficient, water abstraction and the initial depth to water table to find the internal class and percentage score of each input parameter. Analysis have been performed with the data from January 1993 to June 1995. The linear combination model was first calibrated using data for January 1993 to April 1994 by varying the percentage score of each input parameter so that the GIS output of water level agrees with field observation. The model is then verified for the period May 1994 to June 1995. Keeping the total abstraction same, four alternative were designed by changing the distribution of water abstraction patterns with additional pumping in the North, South-West, North-West and West, one area at a time and the monthly water level change was then the predicted for the period January 1995 to December 1997. It was found that, the wellfield expansion in the North-west area could be possible without having unacceptable waterlevel change in Zone 1 and around the Y om river during the prediction period. |
