Results

Results for the Mahakam Cluster research will be posted as the project progresses. Some early results and data gathered from the completed field seasons are available below.

Simulating the Holocene development of the mixed tidal-fluvial Mahakam delta
Data Report WP1
All data gathering for this project has ceased, there are no further plans for extra data gathering in the near future. The first phase of the fieldwork consisted of a combined subsurface echosounder survey and a coring campaign. The ten mechanical corings (up to 25.5 m deep) were carried out in combination with WP 3. A second field campaign in the Mahakam delta was performed using a higher resolution echosounder;the detailed very high-resolution seismic/bathymetric survey resulted in a survey of unprecedented detail in the subsurface characterization of the Holocene Mahakam deposits.

Rainfall-runoff modelling in large tropical poorly gauged basin - The Mahakam River, Kalimantan
Data Report WP4
Surface water level, Groundwater level and rainfall were set along the Mahakam river. The data has been collected over an interval of more than one year.

Discharge regimes, morphometry and tides in the Mahakam delta channel network
Data Report WP5
Data analysis has been focused on water level variation along the river from the outer delta until the lakes area. water level sensors at selected locations along the river and in the delta, salinity sensors in the delta, a horizontal ADCP discharge station and a turbidity sensor near Samarinda city. After installing the permanent stations for long-term measurements, several surveys were conducted to collect bed samples, bathymetry and hydrography along the study area (from Samarinda until the delta apex). In total, eight hydrographic surveys were completed during spring and neap tides.

Stakeholder interests and the potential for sustainable coastal management through rights regulation practices in the context of decentralization in the Mahakam Delta
Data Report WP8
This research aims to examine and detail the evolvement of formal and informal arrangements for the use of natural resources in the Mahakam Delta. On the basis of socio-legal research at the level of the state and the people, the researches will propose improvements of the laws and regulations of the use rights, in particular with respect to shrimp aquaculture and fishery. Literature research and fieldwork has been done.
