30^th October, 2021

• Introductory lecture on storm water drainage
• Introduction to SWMM  modelling approach for catchment runoff generation following a storm, routing of flow along storm drainage network. Introducing  SWMM Reference Manual Vol. I and Vol. II Hydrology and Hydraulics
• Installation of the SWMM modelling software and introducing the use of SWMM Reference Manual
• Demonstration of SWMM application potential using a Case study already carried out for an urban storm water drainage development project in an urban are of Sri Lanka

1^st November, 2021

• Hands on guidance to set up the model for an area using the Tutorial activity demonstration. Setting up of catchment hydrologic parameters, drainage network and its hydraulic parameters properties using the interactive tools provide by the SWMM software (Ref, EPA SWMM User’s Manual Version 5.1)
• Participants were guided to gain experience in model setting up and confidence in running the model, and familiarizing  presentation and interpretation of model generated results using display and reporting tools provided by the SWMM software.
• Running of SWMM Model together with participants for an already set up Case study of SWMM application for Sainthamaruthu area in Sri Lanka to demonstrate the selection of design storm, design of runoff collection /junctions, canal/pipe networks, outfall etc.
• Participants were given an assignments to carry out analysis and design of a storm water drainage system for a design storms of a selected area using SWMM

5^th November, 2021

• Presentations by the participants on the developed design in their selected  area. Discussion class  to clarify the questions and issues cropped up during the  model application for analysis runoff and sizing of conveyance elements of the network

• Introduction to SWMM  modelling approach for pollutant generation following a storm, routing pollutants with of flow along storm drainage network. Introducing  SWMM Reference Manual Vol.III  Water Quality and representative concentrations of pollutants
• Tutorial activity demonstration based on Chapter 2 in EPA SWMM User’s Reference Manual Version 5.1

10^th November, 2021

• Introduction of LIDs and explanations on LIDs introduction in SWMM   for the runoff regulation and water quality improvement (SWMM Reference Manual Vol. III) 
• Running of SWMM Model for water quality parameters together with participants for an already set up Case study of SWMM application for Sainthamaruthu area in Sri Lanka to demonstrate t introduction  of control parameters for water quality modeling and model applications together with interpretation of results using SWMM tools
• Case study of deployment of  LIDs  and impact of LIDs
• Participants were given an assignments to carry out analysis of water quality for a design storms of their  selected area using SWMM. Also, to introduce LIDs in their area and investigate the impact LIDs on runoff regulation and water quality improvement

12^th November, 2021

• Presentations by the participants on the water quality modelling applied to selected pollutant concentrations in their selected area. Discussion class to clarify the questions and issues cropped up during the  model application for analysis concentrations and introduction of LIDs.
