Abstract

The groundwater vulnerability map is an important theme used in the preparation of a groundwater resource planning map. Using intrinsic vulnerability principles (NRC, 1993, Vrba & Zaporozec, 1994) a parameter rating system (termed overlay and index system by some authors) was devised for each city to make the best use of available data. In each case, a simple relative vulnerability index was applied to each component (High/Moderate/Low/Negligible scored 3, 2, 1, 0 respectively) then a vulnerability classification based on the sum of component theme scores. The system for Narayanganj is described. Groundwater vulnerability maps for Bishkek and Narayanganj are given.
