NATIONAL REPORT ONTHE PLATFORM ACTIVITY
 03 Plenary Sessions were conducted at Irrigation Department with allstakeholders and ICHARM

4NATIONAL REPORT ON
THE PLATFORM ACTIVITY
 South Asian Regional Hub of RIMES has been established in ID

premises.

 We anticipate ICHARM also establish their division in the ID and tobe linked with all stakeholder institutions in Sri Lanka

 IWMI want to collaborate with RIMES & ICHARM

5PROPOSAL OF
CAPACITY DEVELOPMENT Early Flood Warning Center has been established in ID

premises, and this center will be fully equipped with allnecessary resources with the assistance of World Bank underCResMP Need training especially for Young Engineers on,• Flood modelling and forecasting• Whether forecasting including Rainfall
 We propose all the stakeholders who own Weather Stations,Rainfall Stations and River Gauges to establish a common
system for the purpose of forecasting while keeping theirseparate systems.

 Gauges fixed by ICHARM also to be linked in to that system

ROADMAP/STRATEGIC WAY FOR
GLOBAL AGENDA• ID’s expectation is to provide flood early warning with sufficientlead time all over the Island in near future. This will contribute toreduce flood damages greatly.

• On the other hand ID is planning to implement structural flood

counter measures under CResMP. As the first step flood protection
works for Kelani River would be implemented with a large investment.

• We have studied 11 large river basins to prepare future Developmentof Basin Investment Plans to mitigate flood and drought.

• Water Resources Development by River Basin approach

Those steps are complying with Global Agenda (Sendai Framework,
SDGs and Paris Agreement)

ROADMAP/STRATEGIC WAY FOR
GLOBAL AGENDA• KnoWat (Knowing Water Better) Project will be launchedby the Irrigation Department with other stakeholders with
the Assistance of FAO (Remote Sensing Technologies toassess water in the basin, Water Accounting and Auditing &Water Tenure)• Adaptation Strategies to Climate shocks in the North Central

Province of Sri Lanka by IWMI to be launched

Those steps are complying with Global Agenda (SendaiFramework, SDGs and Paris Agreement)

Roadmap/Strategic way for Global Agenda
Important for better Public Weather Service (PWS) / Early Warnings for DRR
DEPARTMENT OF METEOROLOGY - SRI LANKA

Three important global agreements Sri
Lanka has recently committed to• Sendai Framework for Disaster Risk Reduction

At the 3rd UN World Conference on DRR in March 2015 countries
adopted the SFDRR, a 15-year, voluntary, non-binding agreementthat aims for the substantial reduction of disaster risk and losses inlives, livelihoods and health and in the economic, physical, social,
cultural and environmental assets of persons, businesses,communities and countries.

We are here

• Sustainable Development Goals

In September 2015, countries adopted a set of goals to end
poverty, protect the planet, and ensure prosperity for all as part ofa new sustainable development agenda.

• UNFCCC/Paris Agreement

Source : WMO

At the Paris climate conference (COP21) in December 2015, 195
countries adopted the first-ever universal, legally binding global
climate agreement. The agreement sets out a global action plan toput the world on track to avoid dangerous climate change bylimiting global warming to below 2°C.

Challenges and Gaps
Integrated Forecasting System
Output from different meteorological observation
systems, numerical weather products, satellite
imagery and forecast tools are analyzed separately inarriving at the weather forecast.
Accuracy of the forecast can be improved bydeveloping an integrated forecasting system

Data Collection, Quality Control andArchival system
Meteorological/climatological processing and archival
system based on personal computer environment isbased on WMO supported CLICOM and CLIMSOFT
database management systems.

Public Weather Service

User Services for Major sectors

Public Weather Service is to strengthen the capacity
and skill to meet the needs of the users throughdelivery of comprehensive weather services.

Quality of meteorological data and forecast is crucial toensure the safety of flights.

Necessary to establish a public weather service
system capable of delivering the user requiredservices.

To enhance the services provided to aviation sector apilot briefing system with direct web based access isrequired to be installed at Katunayake InternationalAirport

 Action has been taken to Implementation of Modernization Project of the Department ofMeteorology with the assistance of World Bank Need training of officials especially Young Meteorology to train on forecasting including: Numerical Weather Prediction
 Forecast verification theory & basics
 Radar Meteorology &satellite imagery and forecast tools are analyzed separately inarriving at the weather forecast.
 Public Weather and Early Warning Service training
