In detail, Bolgoda (north) Lake and Bolgoda South Lake, which the Bolgoda river connects, are two vast freshwater bodies that cover an area of approximately 400 square kilometers. In addition to Bolgoda Lakes, the Bolgoda Basin consists of five other lakes: Boralesgamuwa, Gamanpila, Kes-bewa, Uyanwatta, and Walgama and the Lunawa Lagoon. This wetland complex has been listed in the “1001 Natural wonders of the world: you must see before you die”, published in 2017 by Michael Bright (Ed.), due to its ecological, social, and economic significance. Bolgoda wetland usually receives considerable rainfall throughout the year, with peaks during the monsoons. Weras river, which travels through a major garbage dumpsite and an industrial zone, delivers the primary water source to the Bolgoda Lakes and the rain and runoffs from two small streams named Panape Ela and Rambana Ela fed by Maha Oya [1]. Further connections of the Bolgoda hydrological system exist through Bolgoda Canal & Kirulapone Canal to Kelani Riv¬er, through Keppu Ela to Kalu Ganga, and through Thalpitiya Ela to the ocean south of Panadura Estuary.","PeriodicalId":246166,"journal":{"name":"Bolgoda Plains","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116896514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There was only one university those days. My career at the University of Moratuwa started when the newly established Ceylon College of Technology (CCT) was started with virtually the university status, and they wanted to hire academic staff members. I was at the University of British Columbia, Canada at that time. Prof. Kuruppu sent me a letter telling that he joined CCT, and asking to join as well. I applied from Canada. Since CCT was a government institution, the Sri Lankan High Commissioner came in person from Ottawa to UBC to interview me. I completed my PhD in Electrical Engineering in 1969, and was selected for the job. Later, the institution became a campus of the University of Sri Lanka. In 1972, I was the first Dean of Engineering and Architecture. Architecture at that time was a mature department operating under the University of Colombo, and they were shifted to Katubedda, and joined with the engineering programme. Later, after my time, the faculties were separated due to growth in different directions.","PeriodicalId":246166,"journal":{"name":"Bolgoda Plains","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126086808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

That has created a significant traffic congestion on roads which is one of the critical issues in urban roads in Sri Lanka. Improving PT service quality and promoting PT among people would be one solution. The existing service quality of PT should be identified first and expected improvements should be captured. Many researchers have identified “Level of Service (LOS)” as an efficient tool to measure PT service quality [1]. Transit Capacity and Quality of Service Manual highlights the importance of user’s perception for determining level of service [2]. This research attempt to quantify the existing LOS of PT based on bus passengers’ opinion gathered through a questionnaire survey from route between Galle to Colombo. From the literature review, the study identified around 15 factors which affect the LOS of PT and incorporated them into the survey.","PeriodicalId":246166,"journal":{"name":"Bolgoda Plains","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123815333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
