The general aim
of this research effort is to evaluate - on the basis of a diverse but highly co-ordinated
network of measurements and techniques - the impact of urbanisation on integrated drainage
basin hydrology and water resources in and around the rapidly expanding city of Ramallah.
Extensive field campaigns provide the basis for a detailed
understanding of the complex hydrological system and enable the sound parameterization of
hydrological models. All information is gathered in a commonly accessible GIS-based
database.
The project aims to contribute to following problem areas:
- How much flooding increase will be caused to the densely populated
downstream (Israeli) reaches of the streams by various scenarios of upstream (Palestinian)
urbanization increase?
- What is the impact of urbanization on the quality of storm water in
urban drainage systems and natural wadis?
- How sensitive are local springs and the mountain aquifer to
infiltration of sewage or polluted floods in the wadis and on the karst surfaces?
- Where are the most vulnerable zones (in terms of intrinsic and
specific vulnerability) where urban development should be strictly controlled or even
banned and what type of water resource do they mostly endanger?
- What is the real, on-terrain hydrologic balance in the intake areas
of the local springs and of the mountain aquifer? This question, with emphasis on the
processes at and close to the surface, has been answered up to now only in very general
terms based on total aquifer water balance drawn from distant well data.
