Modelling the Al Ghadit and Al Assi catchments

The HAWKAMAA-EU project aimed to build the capacities of water governance actors – public institutions and civil society – to deliver sustainable services to local host and refugee communities in Lebanon.
The project was implemented by a consortium of non-governmental organisations that included ACTED, We World-GVC, Solidarités International, Action against Hunger, and Lebrelief, with the support of Lewap.
The purpose of the study was to support effective multi-stakeholder decision-making and action through water balance modelling to improve water resource conservation and management in two basins to maximise economic, environmental and social benefits (Al Ghadir and Al Assi). Additionally, previous ongoing work was continued for a third basin (Al Ostuan River basin).
The “Water Evaluation and Planning” (WEAP) modelling software was used. This is a tool that takes an integrated approach to water resources planning and enables both hydraulic and socio-economic conditions to be taken into account. The outputs of these water balance models were assessed and translated into policy-relevant targets, and used to further support the design of measuring programmes to achieve these targets.

Type of service provided :

The activities included in this project involved:

  • Conducting a desk review and collecting data;
  • Carrying out water quality testing through two campaigns to acquire samples for physio-chemical analysis (turbidity, BOD5, COD), metal analysis and Organophosphorus Pesticides Analysis (OPPs);
  • Developing MODFLOW and WEAP related models for baseline water balances including climate change projections to 2035;
  • Defining policy-relevant targets for the measuring the programme action plan. The measures assessed include: Water saving fixtures / Domestic greywater reuse / On-site rainwater harvesting / Increasing irrigation efficiency (both field application and conveyance efficiency) / Precision agriculture / Natural water retention measures (e.g. detention and retention ponds);
  • Facilitating 2 on-site workshops to ensure stakeholder engagement in the catchments;
  • Holding a final workshop to present and discuss the results.
