The Ministry of Mahaweli Development and Environment (MMDE) with the assistance of the United Nations Development Programme in collaboration with the Department of National Planning (NPD), Ministry Irrigation and Water Management (MIWM) Ministry of Agriculture (MA), Ministry of City Planning and Water Supply and Ministry of Disaster Management, secured financing from the Green Climate Fund (GCF) to implement a USD 38.1 million project aimed at strengthening the resilience of Smallholder farmers in the dry Zone to climate variability and extreme events.

This Project will support the Government to implement integrated solutions to water management in three river basins in the Dry Zone of Sri Lanka. The Project aims to achieve higher levels of food, livelihoods and water security for flood and drought affected poor communities. GCF resources will be invested in improving access to irrigation and eco-system based agricultural practices, improved community managed drinking water infrastructure, scaling up decentralized drinking water systems and strengthening early warning, forecasting and climate advisories to protect farmers, particularly women from climate related impacts.

The Project will benefit 750,000 people living in the three river basins directly through investments in irrigation, drinking water and disaster risk management. Moreover, around 770,000 people living in these districts will indirectly benefit from the project interventions in capacities and early warning systems. Under this Project, which will be implemented from 2017 to 2024 UNDP will work with a number of government institutions to deliver the Project outputs and activities and measures its impacts.

The Project covers three key components:

  1. Component 1: Climate resilient investment to rehabilitate small tank-based cascading systems and related infrastructure and facilitate sustainable, climate-proof agricultural practices in targeted areas  
  2. Component 2: Investments to increase access to and quality of drinking water in remote and rural areas through a multi-pronged partnership approach that seeks to replenish sources, build storage, purify contaminated water and address root causes of water quality issues
  3. Component 3: Improve community access to timely early warning for flood and drought to avoid losses and impacts on key livelihood assets. This includes the generation, coding, modelling, dissemination and access to weather related data/knowledge including advise and early warning.

The Project implementation modality includes a Project Management Unit established under the Ministry of Mahaweli Development and Environment with the Project Director, Deputy Project Director, Project Accountant and other project staff. UNDP as the responsible party for Project assurance will provide technical assistance to implement the Project. Under this, the service of a team of technical specialists will be provided by UNDP to facilitate the implementation of the Project. Further, a national level technical advisory committee will be established to obtain specialist advice to ensure integrated approach for climate resilient water management.

An important outcome expected from the Project’s interventions is an empowered farmer community who will manage their water and other natural resources using the cascade as the management unit. For this purpose, the Project plans to develop cascade water user organizations, whose responsibilities include, inter-alia, the management and allocation of water within a cascade in an equitable manner. Given the increased uncertainty of weather patterns, this is extremely important to mitigate both the droughts and the floods.

The National Consultant for Water Balance Study will be a part of the UNDP’s technical team for Project implementation and is responsible to develop a water balance study, conduct training needs assessment of the relevant officials of the Department of Irrigation, Provincial Irrigation Departments and Department of Agrarian Development on water management taking climate risks into account, and assist the Training consultants to develop modules based on the outcome of the training needs assessment.


Scope and Objectives

The objectives of this Consultancy are as follows:

  1. To develop a cost effective, user-friendly computer model that will facilitate management decisions related to irrigation scheduling and water allocation among the Tanks within a cascade;
  2. To field test the model in three cascades, representing three river basins (i.e. Mi Oya, Malwathu Oya and Yan Oya);
  3. To assess the training needs of technical staff engaged in water management in village irrigation systems (i.e. Department of Irrigation, Provincial Departments of Irrigation, Department of Agrarian Development) and recommend training programmes;
  4. To provide technical inputs to the Training Consultants to develop and deliver training programmes to address the identified training needs of the technical staff.

The envisaged time frame of the Consultancy is 24 months from 3rd October 2018 to 2nd October 2020.



Part 1. Water balance model development:

The study scope will include the cascades selected for development under the CRIWMP (16 no.s) in Puttalama, Vavniya, Anuradapura and Kurunagala districts.  

In the project, a cascade tank system is proposed to be modelled based on the principles of System Dynamics (SD), a well-known mathematical modeling approach that could be used to study the behavior of dynamic systems. The proposed model will incorporate the dynamic interaction among different sectors that comprise water resources systems, viz., physical components such as tanks, canals, etc., economical aspects, agricultural sector, etc., and hence will support making unique decisions for efficient management of cascade tank systems. Application of SD modeling for global, regional and basin-level water resources system has proven to yield remarkable results, though not many applications is found in literature.

The SD is a rigorous method of system description, which facilitates feedback analysis, usually via a simulation model, of the effects of alternative system structure and control policies on system behavior. Understanding of the system and its boundaries, identifying the key variables, representation of the physical processes or variables through mathematical relationships, mapping the structure of the model and simulating the model for understanding its behavior are the major steps that are carried out in the development of a system dynamics model. SD applications for water management decision making are rarely found. However, the SD model that incorporates the complexities and interaction among different activities in a cascade tank system will prove the usefulness of the modeling approach in terms of strategic decisions on water sharing to help all water-use sectors of the area.

The system model will be developed using the Vensim simulation environment, which facilitates use of the system dynamics modeling objects such as reservoirs, flows, feedback mechanisms and delays. The model will have the flexibility to input data using Excel spreadsheets, ability to adjust the configuration to different cascade geometries and will require minimum modeling skills to operate.

The Consultant shall select one cascade for model development and another one or two for validation as required. These cascades will be selected from the cascades with completed designs.

The Project will provide;

  1. Depth-area-capacity curves;
  2. Tank bed contours;
  3. Water depth measuring gauges in the Tanks;
  4. Approximate estimate of catchment area command area;
  5. Hydrologic linkages among the Tanks.


Part 2. Capacity assessment:

This study will identify the skills and knowledge required among technical personnel to manage village irrigation systems in an integrated manner to enhance climate resilience.

The Consultant shall conduct one to one meetings with the selected representative sample of technical staff (Minimum 15), engaged in the water management of Village Irrigation Systems from the Provincial Departments of Irrigation, Department of Irrigation and Department of Agrarian Development and assess their capacity gaps and training needs using an appropriately designed Training Needs Assessment Tool. Consultant shall identify the suitable sample, while the Project Management Unit will assist the Consultant to fix the meetings at their respective Departments or offices.

Once the training needs of the sample group is obtained and recommended programmes are identified, the consultant shall conduct an interactive workshop to introduce the climate resilience aspects to design and water management in village irrigation systems. The participants will be; irrigation engineers engaged in water management from Northern, NC, NW and Eastern Provinces, DAD engineers and staff of the Irrigation Department from 7 Districts in which CRIWMP is active. The consultant will explain the climate resilience objectives and the skill required, and explain the findings of the training needs assessment conducted with the representative group and validate the findings. The Consultant shall also explain the recommended programmes and verify and validate the programmes that should be offered for the technical staff. The consultant may engage other resource persons’ subject to the concurrence of the UNDP. The output will be a report describing the training programs required to ensure climate resilience.

The Project Management Unit will organize the logistics of the Workshop, including inviting the participants in consultation with the Consultant.
