TLDR
In this paper, the benefits achieved due to implementation of IWRM in parts of Khulna and Jessore districts, and investigate some technical aspects evolving TRM have been investigated.Abstract:
The south west coastal zone of Bangladesh have been affected by rampant water logging due to vulnerable climate, silted rivers and stumpy terrain; and introduction of IWRM and TRM at some places of the zone has substantially safeguarded the circumstance. This study aims to assess the benefits achieved due to implementation of IWRM in parts of Khulna and Jessore districts, and investigate some technical aspects evolving TRM. Analyses have been carried out using satellite images, RS and GIS technology, Digital Elevation Model (DEM) and field investigations. A mathematical formulation has been made to assess rate of tidal sedimentation due to TRM and selection strategies of tidal basins. The study comes up with evidences of considerable advancements in regional livelihood i.e. flood resistance, cultivated lands, cultivable area, cropping intensities and food security due to IWRM. Moreover, the technical facts established on TRM would help planners to have vivid perception regarding the process.read more

Tidal river management in the south west Ganges-Brahmaputra delta in Bangladesh: Moving towards a transdisciplinary approach?
TL;DR: In this paper, a transdisciplinary approach is examined for its potential to inform the re-shaping of Tidal River Management (TRM) governing values and actions, supported by the active involvement of key agencies and local stakeholders.

TL;DR: In this paper, the authors reveal that >600 km of these major waterways have infilled in recent decades, converting to land through enhanced sedimentation and the direct blocking of waterways by embankments and sluice gates.

Social learning for adaptive delta management: Tidal River Management in the Bangladesh Delta
TL;DR: In this paper, the authors analyzed Tidal River Management in Bangladesh from a social learning perspective and found that social learning occurred more prominently at individual stakeholder level and less at the collective level.

Robust-yet-fragile nature of partly engineered social-ecological systems: a case study of coastal Bangladesh
TL;DR: In this paper, a case study analysis of the long-term changes in the SES shows that although the modifications helped with stability in short time scales, the resulting changes also induced unforeseen problems such as infrastructure maintenance issues, land degradation and sinking, and exposure to market volatility.

Observations and scaling of tidal mass transport across the lower Ganges–Brahmaputra delta plain: implications for delta management and sustainability
TL;DR: In this article, the authors studied the sediment transport in the Sundarbans National Forest and found that sediment transport is flood-oriented, likely as a result of flood-inducing pumping by the main-stem rivers.

Effect of Flow Depth, Ions, and Salinity on Suspended Sediment Concentration
TL;DR: In this paper, the effects of flow depth, ions, and salinity on the evolution of suspended sediment concentration (SSC) are presented, and experiments are conducted in an annular flume using three different sediments (Rhine mud, alumina, and silica) in ionic and saline water.
