Abstract: 

The research presented is based on the detection of groundwater flow system in Lagharak polje area, Kuhrang karstic environment. In this regard, Sinkholes, Linear features and Drainage pattern data are recognized to groundwater flow system indicators, which could be detection recharge, intermediate and discharge areas in karstic system, identified and extracted through the use of field checking, digital elevation modeling and digital image processing of data acquired by Landsat Satellite's TM & ETM+ sensors. The development of these features in study area, trinity zones of ground water flow system limited to the recharge and discharge areas.
Landsat 5 & 7 Satellite's TM & ETM+ sensors spectral bands fusion and ETM+ sensor panchromatic bands can be used as an complementary step to spectral and spatial resolution of this sensors in visual and digital interpretation techniques which enables us to study and analyse groundwater flow system indicators in a shorter period of time.
