Analysis of free groundwater vulnerability level to pollution using “DRASTIC METHOD” development in surakarta city
نویسندگان
چکیده
Increasing population density affects clean water reserves in Surakarta City. Free groundwater 2015 during the transition season Solo is merely 1.34 billion L, whereas amount of confined at same time up to 21 L. population's requirement, however, 51 million L/day or 18.62 L/year; therefore, it predicted that well crisis will occur 2020. Population growth rate and emergence other supporting facilities result a rapid change agricultural lands into housing industrial areas. The land utilization conversion becomes one pollution sources contributes entry pollutants groundwater. This research aims find out free vulnerability level distribution each DRASTIC parameter as for City territories. conducted using weighting method appraisal consists parameters main development parameter. According data obtained, overall territories indicates high pollution. Factors are estimated influencing include: soil texture dominated by loam, sand, gravel, utilization.

modification of drastic model to map groundwater vulnerability to pollution using nitrate measurements in agricultural areas
drastic model has been used to map groundwater vulnerability to pollution in many areas. since this method is used in different places without any changes, it cannot consider the effects of pollution type and characteristics. therefore, the method needs to be calibrated and corrected for a specific aquifer and pollution. in the present research, the rates of drastic parameters have been correct...

Aquifer Vulnerability Assessment for Sustainable Groundwater Management Using DRASTIC
Groundwater management and protection has been facilitated by computational modeling of aquifer vulnerability and monitoring aquifers using groundwater sampling. The DRASTIC (Depth to water, Recharge, Aquifer media, Soil media, Topography, Impact of vadose zone media, and hydraulic Conductivity) model, an overlay and index GIS model, has been used for groundwater quality assessment because it r...
