Geographical features See documents: GO1, GO2, GO3, GO4 and GO5 LOCATION Mawlamyine is located at the mouth of Thanlwin (Salween) river, at 300 km south-east of Yangon and 45 km from the sea. Figure 1: Location of Mawlamyine city Source : librairie.immatérielle.fr REGIONAL/NATIONAL SIGNIFICANCE Mawlamyine is the capital city of the Mon State and its largest city. It is the main trading centre and seaport in south-eastern Myanmar. The city is located at the crossing of 2 trade corridors: 372 The East-West corridor linking Yangon to Thaïland, Laos and Vienam; The North-South corridor connecting the country's mainland and south-eastern region (in particular the Dawei deep-sea port and special economic zone which are being developed). KEY GEOGRAPHICAL FEATURES The geomorphic features of Mawlamyine city can be divided into 3 main regions: The Western plain which is a coastal plain gently sloping from the mountain ridge toward the Thalwin river. This part of the city is undulating at an altitude lower than 50 feet (~15 meters). The most populated areas of the city are located in this region (see below the distribution of population by ward); The Mountain ranges which include the Yankin ridge in the north and the Taungnyo range in the southeastern part of the city. The Yankin ridge previously constituted the eastern limit of the town but is now its central ridge. The current peak of the city is located in this range at an altitude of 320 feet (~98 meters). The Eastern plain is an almost flat alluvial low lying plain of the Atran river. Less populated that the western part of the city, this area is now developing fast.

Reports from the Geography Department of the University mention that laterite and lateritic soils with granite and sandstone outcrops are found in the Yanking ridge and foothills areas while surrounding plains are old alluvium deposited by the Thanlwin river and its tributaries. On the coastline, mud and sand cover the tidal areas. Engineers from the TDC described the geological conditions of the city as follows: Eastern part of the city (along the Atran river): 5 to 6 feet of clay and lateritic soil below; Western side of the city (along the Thanlwin river): 20 to 30 feet of lateritic soil and rock below. 8 No more detailed topographical map of the city has been found but it is likely that (more) detailed information is available in the part of the city where water projects are being studied. 373 Figure 3: Key geological features of Mawlamyine city Source: Geography Dpt of Mawlamyine University (from Geology Dpt of M. University) CLIMATE Unlike other places of the country where the climate is can be clearly divided into 3 main seasons (rainy season, cold season, hot season), the climate in Mawlamyine is characterized by 2 main periods: A dry season, from November to March with almost no rainfall and average temperatures below 28°C; A rainy season, from April to October with heavy rainfall and average temperatures ranging from 31°C to 26°C. The average annual rainfall is about 5,200 mm. The below table provide the average maximum, minimum and mean temperatures and rainfall measured in Mawlamyine city between 2001 and 2012 while the graph below illustrates the annual rainfall distribution (data from 2012 only).

In that case, area along the Atran river are the most exposed to flooding but it seems that the duration of these phenomenon is limited to a few hours only. The earthquake vulnerability of the area is limited as is the effects of storms or hurricane thanks to the presence of a mountainous range on the boundary with Thaïland. The city is not subject to draught with the 2 rivers (Thalwin and Atran rivers) ensuring a sustainable source of water all year long. 2. Demographic data See documents: DM1, DM2, DM3 and DM4 CURRENT POPULATION According to the national Census 2014, Mawlamyine city’ population is 253,734 inhabitants. It makes it the fifth largest city of Myanmar (after Yangon, Mandalay, Taunggyi and Bago). As shown in the table below, the Township authorities however estimated the population of the city at 217,746 inhabitants as of March 2016. Given the fact that the estimate of the 375 Township is regularly updated on the basis of information provided by each ward administrator, this second figure seems the more realistic. Figure 5: Population by ward as of March 2016 No Ward Population No Ward Population 1 Zay Yar Thiri Ward 8,807 16 Mu Pon Ward 8,668 2 Tharyar Aye Ward 4,776 17 Thiri Myine Ward 10,933 3 Shwe Myine Thiri Ward 19,306 18 Thiri Mingalar Ward 5,119 4 Hlaing Ward 19,760 19 Myay Ni Kone Ward 5,980 5 Kyaiuk Pha Ne Ward 6,317 20 Zay Kyo Ward 12,659 6 Auk Kyin Ward 8,405 21 Myine Thar Yar Ward 2,625 7 Mandalay Ward 4,344 22 Kyauk Tan Ward 8,849 8 Phet Tan Ward 11,306 23 Zay Yar Myine Ward 6,530 9 Shwe Taung Ward 8,382 24 Naung Kha Ye Ward 5,052 10 Sit Ke Kone Ward 6,555 25 Ngan Te Ward 4,350 11 Ma Yan Gone Ward 4,044 26 Chauk Mile Ward 3,642 12 Pabedan Ward 4,539 27 Sann Gyi Ward 1,134 13 Bokone Ward 6,316 28 Gway Gone Ward 4,492 14 Maung Ngan Ward 7,152 29 Nyaung Pin Seik Ward 7,830 15 Kwin Yat Ward 9,874 Total Mawlamyine city 217,746 Source: GAD The exact surface of the city is not known and the density of the population is therefore difficult to assess. The DUHD provides the following estimations: Average population density : 20 inh./acre Highest population density : 68 inh./acre Lowest population density : 1.5 inh./acre POPULATION DISTRIBUTION Till 2010, the city included 22 wards. 6 news wards were included in 2011 and a 29th has been included in 2015. The below map shows the density of population in each ward. One can see that the densest areas are located in the north-western part of the city. Figure 6: Density of the population in each ward of the city [inh./acre] (2013) 376 Source: DUHD GROWTH RATE A table with the city population growth from 1943 to 2014 has been found in a report of the Geography Department of Mawlamyine university (see document DM4). Figures are however highly questionable since the table indicates almost 450,000 inhabitants for the year 2011 while the current population of the city is estimated at 217,746 inhabitants (see above)9. Since the last official census at national level was conducted in 1983, the growth rates likely stem from estimation and should therefore be considered with caution. According to the last census (2014), the growth rate at national level is 0.89%. This figure seems quite low, especially considering the increasing urbanization process of the Myanmar society. The DUHD estimates that the realistic growth rate to be applied for projections in Mawlamyine is 2.2%. This means that the population of the city would evolve as follows: Figure 7: Projections of population for Mawlamyine city based on an annual growth rate of 2.2% 2016 2020 2025 2030 2040 9 The figure of the table for the year 2011 would not be consistent either with the population in the entire township which is estimated at 289,388 in the last census. 377 217,746 237,549 264,855 295,300 367,089 FLOATING POPULATION The city of Mawlamyine is not subject to a significant phenomenon of migration.
