Work Package 3
River ecology and river basin management

Within work package 3 the ecological status of the water bodies in the model region will be assessed and river management plans will be developed. For the ecological assessment physicochemical as well as biological components will be used (benthic invertebrates, fish and diatoms). Moreover, the hygienic status will be assessed by studying the development of faecal bacteria in the rivers. Data will be collected during expeditions in the model region in Mongolia what normally takes several weeks. The results of the field study will be used to assess the ecological status and to identify significant pressures. Particularly, the physico-chemical, hydromorphological and hydraulic pressures will be taken into consideration in combination with land use data. On the basis of the pressures that have been identified a monitoring programme will be developed to assess water quality and ecological status in the long term. Furthermore, we will use numeric simulations in order to predict changes in the ecological status using different management scenarios. The results of the study will be merged with the results of the other work packages of the MoMo project in order to create a scientific basis for river management plans. Work package 3 is conducted by University of Kassel, Centre for Environmental Systems Research, Department INTEGER.


Participants and trainees during the May 2007 Kharaa expedition
Activities of working package 3

September 2006
  • first expedition in the project region and selection of 20 sampling sites in the main river and its tributaries
  • water quality measurements, hydromorphological mapping and sampling for ecological assessment. We decided to use benthic invertebrates, fish and diatoms as biological indicators of the ecological status.
  • conceptual design of PhD thesis of Saulegul Avlush;Topic: life cycle strategies of selected benthic invertebrate species in the Kharaa river basin.
  • Installation of a weather station in the subcatchment Shivertin Gol.
  • Installation of a water gauge and water temperature loggers near the mouth of the River Kharaa.
  • Teaching activities: 2 day seminar at the National Univeristy of Mongolia: "Introduction to Biostatistics". 10 participants



Kharaa river basin and sampling sites for ecological monitoring 7


May 2007
  • expedition in the project region, about 20 researches participated from University of Kassel, National University of Mongolia and Mongolian University of Science and Technology.
  • we conducted a standard measuring program at 20 sampling sites in the Kharaa river basin and in the Eroo river basin. The Eroo river basin serves as a reference. Two additional sampling sites (compared to September 2006) were included.
  • Water level and temperature data were taken from the loggers.
  • Installation of a second weather station in the southern part of the river basin.
  • a four-day field course was organized in co-operation with MOLARE Research Center. 12 students participated in the field course entitled "Methods in Stream Ecology".
  • Lecture and seminar was held by Prof. Dr. D. Borchardt at the co-operating universities in UB. Title of the lecture: "Intruduction to Limnology" and "Water Resources Management".
  • a documentation of the research activities was made by the TV channel ARTE.
  • morphological and hydrological study, resulting in the master thesis of Senta Berner, University of Stuttgart. The master thesis was finalized in October 2007.
  • MSc. Purevdorj Surenkhorloo starts a PhD thesis within the framework of working package 3: " Food-Web interactions of macrozoobenthos and fish in river catchments in northern Mongolia: Impacts of anthropogenic influences."


August/September 2007
  • Expedition in the project region, river Kharaa and river Eroo.
  • Standard measuring program was repeated at 20 sampling sites.
  • BSc. Chantoo starts a bachelor thesis within the framework of the MoMo project: "Habitat preferences of Cobitis melanoleuca in relation to substrate composition and near bottom flow velocities".
  • Data of temperature loggers, water level loggers and two weather stations were read.


February 2008
  • Organization of a project meeting of German project partners in Kassel.
  • We summarized project results from different MoMo working packages in a MoMo Newsletter, which was distributed to all German and Mongolian project partners as well as to Mongolian administration. The newsletter can be downloaded from MoMo internet pages.


March 2008
  • Meetings with Mongolian authorities and ministries, amongst others with Mongolian Ministry of Education and Research, Mongolian Ministry of Urban Construction and Development, Mongolian Ministry of Environment, Water Authority, National Water Commettee and German Embassy in Mongolia. Most important topics during the talks were the development of IWRM strategies and building of scenarios.


April/May 2008
  • expedition in the Kharaa river basin where the standard measuring program was repeated
  • Additionally, fish samples for the analysis of heavy metals were taken from the subcatchment of the Boroo river.
  • Student Zoloo started a bachelor work within the framework of the MoMo project: "Seasonal differences in the availability of autochthonous and allochthonous food resources for drift feeding fish species".
  • Field course and seminar at the river Tuul in Ulan Bator in co-operation with WP1. Topics of hydrology, land use and applied limnology were taught.


20 - 22 May 2008
  • Organization of a MoMo status conference in Ulan Bator by WP3 and project office in Ulan Bator. During the conference we presented latest results from different working packages. About 80 experts from different Mongolian authorities, Mongolian ministries and project partners participated in the conference.


June 2008
  • Finalization of conference proceedings. Latest project results were summarized and all presentations given during the status conference in May were included in the proceedings. The document can be downloaded from MoMo internet pages.
  • 10 day expedition in the project region by Mongolian project partners and PhD students. Samples for ecological monitoring were taken.


July 2008
  • 10 day expedition in the project region by Mongolian project partners and PhD students. Samples for ecological monitoring were taken.


August 2008
  • Expedition in the Kharaa river basin and Eroo river basin. The standard measuring program was repeated for the assessment of hydromorphology, water quality and biology.
