Jordan WEAP - strategic discussion at MWI, Amman, Nov 22nd, 2009

Idea of introducing WEAP to the MWI

The Ministry of Water and Irrigation needs to implement a water resource planning tool for water balances, allocation and transfer for whole Jordan, based on the (NWMP) and the current data of the Ministry’s Water Information System.

The ministry was looking for a software which:

• Is a scientifically improved tool for strategic water resource planning.

• Has a user-friendly and easy learnable interface.

• Is driven in responsibility of the ministries' stuff supported by a national consultant.

• Has a great user community, which is working in similar environment.


Implementation of WEAP

After carefully researching, WEAP was selected as an appropriate tool to fulfil all the requirements to enable the NWMP-directorate to enhance strategic water resource planning.

Organisational setup:

• A WEAP-team with ministries' staff was nominated from different entities (MWI, WAJ) with different scientific background (geologists, engineers).

• The section for “Water Information System”, within the NWMP directorate was establish staff with extra personal from MWI.

• The WEAP-team has been charged to develop and implement a WEAP-model for Jordan with the academically support of a local consultancy (Dr. Abbas Al-OmariUniversity of Jordan and Mr. Markus Huber).


WEAP – Approach - Scale

basin by basin

closed system

high level of detail

not all-in-one

nationwide

all-in-one

low level of detail

extensive maintenance


WEAP Approach - Level of detail

Regional(e.g. Glowa)

Operational(e.g. Corridor well field)

Management


WEAP approach - planning unit

Administration (= Governorates)

data management structure in authoritiesvisualize effects of governorate's decision on GW

Hydrology(= sub-surface water catchments

natural system

input and results need pre-/post processing

Catchment = major planning unit in WEAP


• WEAP-team is working now since 1 year together with the consultants.

• Additional supported by different institutions (ACSAD, SEI, BGR).

• Ongoing work session and on job training take place according to a

common time schedule.

• WEAP-models of Amman Zarqa Basin and Azraq-basin has been

prepared, Jordan Valley and Yarmuk are in process.

• The model includes the hydrological part as well as the supply and demand management.

Jordan Valley WEAP Model

Main source for irrigation is surface water distributed by KAC.

population about 200,000, domestic demand is satisfied from GW sources.


Yarmuk WEAP Model

Demands are mainly domestic and agricultural.

Sources are groundwater from in and outside the basin.

Next Steps• AZB and Azraq are ready and calibrated. Jordan Valley and Yarmuk

are in process.

• Handbook preparation which documents the whole development process as a hardcopy and digital version (WEB-page)

• Scenario formulation, (climate, socio-economic, water strategy are the base).

• On the job training for scenario management in WEAP,

implementation and evaluation, additional advanced user training.

• Economic model MYWAS – Evaluation of the model and the set up

• MODFLOW - model for Azraq, development, evaluation connection

to WEAP as a Pilot study with on the job-training
