Please complete using Word document format.

Please complete a separate questionnaire for each aquifer

Please return by e-mail to: al-mooji@un.org and R.Stephan@unesco.org with copies to: iganouli@civil.auth.gr and a.aureli@unesco.org, by 31st August 2007.

1.         NAME OF THE TRANSBOUNDARY AQUIFER, LOCATION & COUNTRIES

Please give the name(s) or other identification property of the shared aquifer, its approximate location (province, department) and say which countries share it.

The Northeastern Aquifer, shared between Palestine and Israel

 

2.         AQUIFER CHARACTERISTICS

2. 1      Please look at the four simplified pictures below and indicate which of them most closely characterises your transboundary aquifer. If none, please provide a conceptual sketch of your transboundary aquifer in the blank box below.

Please tick: Example 1  2  3  4  5

 

 

 

West Bank

 

Israel

 

North West Bank Cross Section

General Characteristics

Aquifer hydrogeological type porous   karstic     fissured rock

other Predominant lithology  Limestone

Stratigraphic age Cretaceos-Teritiary and Quaternary

Areal extent (km2)1234 (1027 km2 inside the West Bank) and 207 km2... inside Israel..

Population resident in this area and main occupation……~ 560,000… Thickness: mean (m)....1500.........  maximum (m) 2000

Shared international boundary length (km)…50 Km………………………… Dominant groundwater flow direction: from.. ....Palestine.  to ..........Israel..................... (countries)

Link with surface water systems:

Strong            medium         weak

2.3 Map

Please provide a clear map of the transboundary aquifer, including aquifer boundaries and geographical coordinates. The map should preferably be supplied as a GIS-file

 

 

2.4 Hydrogeological Characteristics and Groundwater Use

Rainfall: average annual and seasonal distribution ………average annual rainfall is  500  mm, min 350 mm, Max 1000m………………………

Recharge / discharge area…

The aquifer outcrops areas had to be divided into three different rainfall zones.

The aforementioned total recharge zone in the Northeatern basin (1062 km2) thus is divided into a zone with low rainfall (52 km2), a large zone with medium rainfall amounts (907 km2) and a small wet zone In the mountains (103 km2).

The rain amonts that precipitate over the aquifer outcrops have to be separated to rainfall that occurs in the west Bank gives the following results:

Out of a total recharge sum of 164 MCM/a, 134 MCM/a take place within the West Bank and only 29 MCM/a of recharge are generated within Israel. This equals a ration of 82% recharge takig place in the Palestinian lands and only 18% of  it coming from Israel itself
