The Role of Groundwater Vulnerability in Urban Development Planning

Abstract

Groundwater resources in most places of Iran are considered to be one of the important
 drinking water supplies for civilians. In city of Tehran, 25% of drinking water is being supplied from
 groundwater. This fact would enforce the requirement to protect and conserve groundwater resources
 in the city for its further development plan. Municipality of Tehran, District-22 has been designed for
 the latest and the ultimate development boundary of the city, which is being constructed in the north-west
 part of the city. The groundwater resources of the District are considered as main drinking water
 supplier for its future short term population. Hence due to the importance of groundwater of the
 District, the vulnerability to nitrate contaminant is being examined by means of Drastic Model. The
 results obtained, indicate that due to regional environmental characteristics, vulnerability index varies
 in different parts of studied area. so the eastern and south eastern parts of the District have experienced
 the highest vulnerability. Besides comparing the results with nitrate concentration reveals that
 correlation has been approximately 61% and among the drastic layers, precipitation layer has been
 determined as the most effective parameters for final drastic index layer of studied area. In this regard,
 concerning the vulnerability map, urban land application, including residential and commercial in
 mentioned parts should be prohibited

Evaluation of the Groundwater Global Pollution Risk: Relationships with Territorial Planning

“…In order to implement the aforementioned approaches (Nouri and Malmasi, 2005), it appears indispensable to adopt the Environmental and Social Evaluation procedures related to anthropic impacts on the GWR system, in order to guarantee a balance between the quantity of the urbanized territory and the quality of the urbanization. "Best practices" for the areas marked for urban expansion:…”

Groundwater Resources Pollution Risk: Application of the Holman Method

“…From this work appears, with increasing importance, an integrated approach to the planning and management of the territory which consider all the components associated, both natural and human induced [4,7,11] . Consequently the "territorial planner" represents the person who has the capacity of drawing the right considerations from the results of the technical analyses so that strength and weakness points analyzed about the territory can be found.…”

Groundwater vulnerability to pollution mapping of Ranchi district using GIS

“…Among all the approaches mentioned above, the overlay and index method has been the most widely adopted approach for wide-scale groundwater vulnerability assessments. Scientist started giving predictions of groundwater pollution potential based on hydrogeological settings ( Polemio et al 2009 ; Almasri Mohammad 2008 ; Berkhoff 2008 ; Rahman 2008 ; Massone et al 2010 ; Kwansiririkul et al 2004 ; Kim and Hamm 1999 ; Secunda et al 1998 ; Vias et al 2005 ; Brosig Karolin et al 2008 ; Ferreira Lobo and Oliveira Manuel 2004 ; Nouri and Malmasi 2005 ; Herlinger and Viero 2007 ; Shirazi et al 2012 , 2013 ; Neshat Aminreza et al 2014 ). This paper aims to demonstrate a GIS-based DRASTIC model for groundwater vulnerability assessment of Ranchi district.…”
