Drastic: A Standardized System to Evaluate Groundwater Pollution Potential using Hydrogeologic Setting
TLDR
The DRASTIC methodology as mentioned in this paper is a methodology which allows the pollution potential of any area to be systematically evaluated, and it optimizes the use of existing data and has two major portions: the designation of mappable units, termed hydrogeologic settings, and the superposition of a relative ranking system.Abstract:
DRASTIC is a methodology which allows the pollution potential of any area to be systematically evaluated. The system optimizes the use of existing data and has two major portions: the designation of mappable units, termed hydrogeologic settings, and the superposition of a relative ranking system called DRASTIC. Hydrogeologic settings incorporate the major hydrogeologic factors which are used to infer the potential for to enter groundwater. These factors form the acronym DRASTIC and include depth to water, net recharge, aquifer media, soil media, topography, impact of the vadose zone and hydraulic conductivity of the aquifer. The relative ranking scheme uses a combination of weights and ratings to produce a numerical value, called the DRASTIC Index which helps prioritize areas with respect to pollution potential.read more

A GIS based DRASTIC model for assessing groundwater vulnerability in shallow aquifer in Aligarh, India
TL;DR: In this article, the authors used the DRASTIC model in a Geographical Information System (GIS) environment to find out the groundwater vulnerable zones in shallow aquifers in Aligarh and its surrounding areas, which is one of the fastest growing big cities of north India.

Water vulnerability assessment in karst environments : a new method of defining protection areas using a multi-attribute approach and GIS tools (EPIK method)
TL;DR: In this paper, the authors proposed a multi-attribute method for vulnerability mapping which takes into consideration the specific hydrogeological behaviour of karst aquifers, such as Epikarst, Protective cover, Infiltration conditions and Karst network development.
A Framework for Dealing With Uncertainty due to Model Structure Error
TL;DR: In this article, a framework is presented for assessing the predictive uncertainties of environmental models used for extrapolation, which involves the use of multiple conceptual models, assessment of their pedigree and reflection on the extent to which the sampled models adequately represent the space of plausible models.

Assessment of flood hazard areas at a regional scale using an index-based approach and Analytical Hierarchy Process: Application in Rhodope–Evros region, Greece
TL;DR: A comparison of the outcome with records of historical flood events confirmed that the proposed methodology provides valid results, and the sensitivity analysis concluded to a revised index FHIS (methodology named FIGusED-S) and flood mapping, supporting the robustness of FIGUSED methodology.
