Abstract
The declining quality of surface water resources leads to groundwater exploitation as a source of fresh water. The developing urban environment also increases the need for groundwater resources as freshwater. Each rock in a geology formation has a different ability to transmit groundwater. There are various ways to obtain parameters of hydraulic conductivity and groundwater transmissivity. The commod method were time and cost consuming. The new method for estimation of geohydraulic parameter were needed. This paper aims to estimate geohydraulic parameters using different techniques and approaches and compares them. Geohydraulic parameter based on Heigold approach show the value of transmissivity at the study area in the range of 22.8 - 1307 m2/day. Geohydraulic parameter based on Niwas and Singhal approach indicate the value of transmissivity at the study area in the range of 32.55 - 30245 m2/day.. The highest hydraulic conductivity and transmissivity values were in the southern and northern parts of the study area. In general, the estimation approach was able to estimate the geohydraulic value at the study area.
