    The Metro Colombo Urban Development Project (MCUDP) implemented under the Megapolis and Western Development Ministry is a development project funded by the World Bank and the Sri Lankan government. The World Bank is providing a concessionary loan of US$ million to the MCUDP, while Sri Lankan government is investing US$ million. During the flood occur in , government initiated to reconstruct and modify the area as a wetland. The land was divided into several small islands and artificial canals were made. Currently, park premises serve as a flood detention area by absorbing flood water during heavy storms and reduce inundation of the parliament area.

Experts say Colombo’s long-neglected wetlands could help alleviate worsening floods – and are set to make a comeback as a key pillar of a major flood prevention program. Floods occurred in and during the monsoon, and smaller deluges have happened this year even before the onset of the monsoon, including in the past few days.

A catchment provides the connectivity between physical and hydrological landscape for characterising negative effects on water resources and flooding of the study area.

Climate change, combined with the lack of drainage caused by urbanization contributes greatly to flooding in urban areas. With the intensification of urban floods in recent years posing a. In Sri Lanka, Wetlands have been a lifeline of ancient civilization. Wetlands possess not only ecological significance but economic value as well.

Among the natural wetlands in Sri Lanka, the Bundala, Anaiwilundawa and Maduganga wetlands have been recognised as having international significance.

Similarly man-made wetlands, which are popularly known as “tanks”, play a vital role. The outskirts of Colombo and some patches within the city were once exotic wildlife habitats with unprecedented biodiversity. During the Kingdom of Sri Jayawardhanapura Kotte (), reservoirs, tanks, and wetlands, which provided water for paddy cultivation and acted as flood detention areas, held the biodiversity of Colombo intact.

In the final research paper of this issue, Hettiarachchi, Athukorale, Wijekoon and de Alwis present a long term research project to understand the nature and extent of degradation in a selected segment of the Colombo flood detention area (CFDA) wetlands in Sri Lanka. important flood detention wetland identified by the canal study carried out by NWSDB () and this marsh also forms the Colombo Flood Detention Area (CFDA) with Kolonnawa, Kotte and Bluemendhal.

In most cases you should be able to develop a flood affected property as long as you follow planning requirements to manage flood risk. Chapter E13 of our Development Control Plan PDF, KB explains the local flood-related planning controls. Our Development Control Plan refers to the 1 in year flood level, the Probable Maximum Flood (PMF) level, and the flood risk precincts.

The Metro Colombo Urban Development Project is investing in Colombo’s public spaces, wetlands, and infrastructure to improve its flood resilience, quality of life, and competitiveness.

When completed,residents will have greater protection from flooding and the entire city of over 6 million people will benefit from an improved quality. Seventeen flood detention areas and large lakes for controlling flood have been constructed, with a total storage capacity of billion m3 and a flood storage capacity of billion m3.

Figure 2 illustrates the major structures in the Huaihe river basin. The concept of decentralized flood protection measures is based on the idea of localization and usage of the capability of headwater areas of a flooded catchment to retard runoff as early as possible and at several places at the same time by means of flood detention basins with minimum environmental impact.sized bio- retention or bio- detention basins.
