UNESCO IHE Guide to the reporting structure of the Flood Management and Mitigation Programme - Component 2, Structural Measures and Flood Proofing Component 2 on Structural Measures and Flood Proofing of the Mekong River Commission's Flood Management and Mitigation Programme was implemented from September 2007 till January 2010 under a consultancy services contract between MRCS and Royal Haskoning in association with Deltares and Unesco-IHE. The Implementation was in three Stages, an Inception Phase, and two implementation Stages. During each stage a series of outputs were delivered and discussed with the MRC, the National Mekong Committees and line agencies of the four MRC member countries. A part of Component 2 - on 'Roads and Floods' - was implemented by the Delft Cluster under a separate contract with MRC. The consultancy services contract for Component 2 specifies in general terms that, in addition to a Final Report, four main products are to be delivered. Hence, the reports produced at the end of Component 2 are structured as follows: Volume 1 Final Report Volume 2 Characteristics of Flooding in the Lower Mekong Basin: Volume 2A Hydrological and Flood Hazard in the Lower Mekong Basin; Volume 2B Hydrological and Flood Hazard in Focal Areas; Volume 2C Flood Damages, Benefits and Flood Risk in Focal Areas, and Volume 2D Strategic Directions for Integrated Flood Risk management in Focal Areas.

Two survey conducted in Ulu Belayan river streams, Mahakam river drainage, District Kembang Janggut, Regency Kutai Timur, Province East Kalimantan. This third survey studied the freshwater fish diversity around Mesangat watershed, District Muara Ancalong, Regency Kutai Kartanegara, Province Kalimantan Timur. There is a quite big swampy area in the District Muara Ancalong, Mesangat swamp or in Bahasa Indonesia we call it Rawa Mesangat. This swamp area is the habitat of the protected species of long snout crocodile, Tomistoma schlegeli. The aim of this survey is to get the information of the fish diversity around Mesangat watershed, the distribution of each site and the status of the species. The results of this survey could be use as the basic data for REA KON to manage the area for the continuation and conservation of the species.

  • Passeriformes: Cisticolidae: Orthotomus) from the Mekong Floodplain of Cambodia
    FORKTAIL 29 (2013): 1–14 http://zoobank.org/urn:lsid:zoobank.org:pub:F1778491-B6EE-4225-95B2-2843B32CBA08 A new species of lowland tailorbird (Passeriformes: Cisticolidae: Orthotomus) from the Mekong floodplain of Cambodia S. P. MAHOOD, A. J. I. JOHN, J. C. EAMES, C. H. OLIVEROS, R. G. MOYLE, HONG CHAMNAN, C. M. POOLE, H. NIELSEN & F. H. SHELDON Based on distinctive morphological and vocal characters we describe a new species of lowland tailorbird Orthotomus from dense humid lowland scrub in the floodplain of the Mekong, Tonle Sap and Bassac rivers of Cambodia. Genetic data place it in the O. atrogularis–O. ruficeps–O. sepium clade. All data suggest that the new species is most closely related to O. atrogularis, from which genetic differences are apparently of a level usually associated with subspecies. However the two taxa behave as biological species, existing locally in sympatry and even exceptionally in syntopy, without apparent hybridisation. The species is known so far from a small area within which its habitat is declining in area and quality. However, although birds are found in a number of small habitat fragments (including within the city limits of Phnom Penh), most individuals probably occupy one large contiguous area of habitat in the Tonle Sap floodplain. We therefore recommend it is classified as Near Threatened on the IUCN Red List. The new species is abundant in suitable habitat within its small range. Further work is required to understand more clearly the distribution and ecology of this species and in particular its evolutionary relationship with O. atrogularis.

    FLOODPLAIN RIVER FOOD WEBS IN THE LOWER MEKONG BASIN A Dissertation by CHOULY OU Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY Chair of Committee, Kirk O. Winemiller Committee Members, Masami Fujiwara Thomas D. Olszewski Daniel L. Roelke Head of Department, Michael Masser December 2013 Major Subject: Wildlife and Fisheries Sciences Copyright 2013 Chouly Ou ABSTRACT The Mekong River is one of the world’s most important rivers in terms of its size, economic importance, cultural significance, productivity, and biodiversity. The Mekong River’s fisheries and biodiversity are threatened by major hydropower development and over-exploitation. Knowledge of river food web ecology is essential for management of the impacts created by anthropogenic activities on plant and animal populations and ecosystems. In the present study, I surveyed four tropical rivers in Cambodia within the Mekong River Basin. I examined the basal production sources supporting fish biomass in the four rivers during the dry and wet seasons and explored the relationship between trophic position and body size of fish at various taxonomic levels, among local species assemblages, and across trophic guilds. I used stable isotopes of carbon and nitrogen to estimate fish trophic levels and the principal primary production sources supporting fishes. My study provides evidence that food web dynamics in tropical rivers undergo significant seasonal shifts and emphasizes that river food webs are altered by dams and flow regulation. Seston and benthic algae were the most important production sources supporting fish biomass during the dry season, and riparian macrophytes appeared to be the most important production source supporting fishes during the wet season.

  • Freshwater Snail Diversity in Mae Lao Agricultural Basin (Chiang Rai, Thailand) with a Focus on Larval Trematode Infections
    ISSN (Print) 0023-4001 ISSN (Online) 1738-0006 Korean J Parasitol Vol. 56, No. 3: 247-257, June 2018 ▣ ORIGINAL ARTICLE https://doi.org/10.3347/kjp.2018.56.3.247 Freshwater Snail Diversity in Mae Lao Agricultural Basin (Chiang Rai, Thailand) with a Focus on Larval Trematode Infections Kittichai Chantima*, Krittawit Suk-ueng, Mintra Kampan Energy and Environment Program, Faculty of Science and Technology, Chiang Rai Rajabhat University, Chiang Rai 57100, Thailand Abstract: The aim of this study was to conduct a freshwater snail survey in Mae Lao agricultural basin to assess the di- versity with a focus on habitat types and their larval trematode infections. Snails were collected and examined in 14 sites of Mae Lao agricultural basin from August 2016 to October 2017. A total of 1,688 snail individuals were collected and classified into 7 families, 8 genera, and 12 species. Snail diversity and habitat types were higher in rice paddies than irri- gation canals and streams. The most abundant species was Bithynia siamensis siamensis, representing 54.6% of the sample. Three species of snails act as first intermediate host were found with cercarial infections. They were Filopaludina sumatrensis polygramma, B. s. siamensis, and Melanoides tuberculata. The cercariae were categorized into 7 types; echi- nostome, monostome, gymnocephalous, virgulate, parapleurolophocercous, pleurolophocercous and megalurous cer- cariae. Parapleurolophocercous cercariae constituted the most common type of cercariae recovered, contributing 41.2% of all infections in snails. Echinostome metacercariae infections were found in 6 snail species with 7.6% prevalence. In addition, the metacercaria of avian trematode, Thapariella sp. were found in Filopaludina spp.

We explored all of these and more during our 25-day adventure across the country. Highlights were many and included Orange River Francolin, thousands of Cape Gannets, multiple Secretarybirds, stunning Knysna Turaco, Ground Woodpecker, Botha’s Lark, Bush Blackcap, Cape Parrot, Aardvark, Aardwolf, Caracal, Oribi and Giant Bullfrog, along with spectacular scenery, great food and excellent accommodation throughout. ___________________________________________________________________________________ Despite havoc-wreaking weather that delayed flights on the other side of the world, everyone managed to arrive (just!) in South Africa for the start of our keenly-awaited tour. We began our 25-day cross-country exploration with a drive along Zaagkuildrift Road. This unassuming stretch of dirt road is well-known in local birding circles and can offer up a wide range of species thanks to its variety of habitats – which include open grassland, acacia woodland, wetlands and a seasonal floodplain.
