Consultant: Water Resources

International Water Management Institute (IWMI)

Amman, , JO


International Water Management Institute (IWMI) seeks the services of a Water Resources Engineer to undertake a short-term assignment in Jordan for the Water Innovations Technologies (WIT) project.

Project Background

IWMI is a sub-awardee of the Water Innovations Technologies (WIT) Program, Cooperative Agreement No. AID-278-A-17-00002 signed between USAID and Mercy Corps. The goal of this project is to “Increase water conserved in Jordan”. The set of indicators for this program includes volume of water used for agriculture through to domestic and community use and the target is a reduction of 18.6 Mm3 of water over the five-year period of WIT.

IWMI, as sub-recipient of WIT, contributes with various components and activities to WIT, such as Monitoring, Evaluation and Learning (ME&L), this includes the learning agenda. The objective of the learning agenda is to generate a learning and knowledge that will produce evidence to accompany the implementation of WIT.

Through this Learning Agenda, IWMI will lead in providing knowledge and learning to the project in order to identify, address, and reduce the challenges and risks for the project and the delivery of project outputs and outcomes.

WIT wishes to understand the amount/rate of non-beneficial evaporation from open water surfaces in the Northern and Middle governorates in Jordan and seeks the services of a consultant as described below.

Objective of the Assignment

The objective of the assignment is to estimate the evaporation of water from open water surfaces (ponds, lakes, reservoirs) in the northern and middle governorates. The consultant shall submit a method statement for IWMI’s review prior to applying the methodology to estimate net evaporation from open water surfaces. The methodology shall review all current practices, tools, techniques for estimating evaporation from water surfaces, critique these contemporary practices to make a case for the preferred method. The preferred method should be appropriate to the context i.e. Jordan and the method statement should clearly articulate how estimates might be verified with ground/in-situ data. After review of the methodology by IWMI and incorporating/responding to comments, the Consultant shall apply the methodology to estimate the 10 year average annual evaporation from open water surfaces in the northern and middle governorates of Jordan. This shall be disaggregated by month and shall be estimated as gross evaporation and net evaporation (i.e. adjusting for precipitation).

The consultant shall be responsible for all data collection required for this analysis and to produce the maps and s/he shall submit a final report that will include the maps and a discussion of the analysis results.

Scope of Work

This study is limited to Jordan and in particular the northern and middle governorates. The Consultant shall specify the governorates in the Method Statement. The estimation shall be limited to evaporation from open water surfaces, the consultant shall specify in the method statement the criteria for selecting open water surfaces. The estimates shall be based on time series data (spatial, in-situ) for the previous one decade i.e. 2009-2019 or as appropriate and shall specify this in the Method Statement.



  • MSc/MS Water Resources Engineering or Equivalent, BSc/BEng Civil Engineering.
  • Good knowledge of water resources challenges of Jordan, experience in analysis of remote sensing data to estimate water evaporation.
  • Analytical skill using remote sensing data, ground truth estimates with in-situ observations.

Duration: Fourteen (14) days over a period of one (01) month
