孟加拉国西南沿海地区由于气候脆弱、河流淤塞和地形不平坦而遭受了严重的水涝;在该地区的一些地方实行水资源综合管理和热带雨林管理大大保护了这一环境。本研究旨在评估库尔纳和杰索尔县部分地区实施水资源综合管理所取得的效益，并调查一些技术方面的问题，以推动TRM的发展。利用卫星图像、RS和GIS技术、数字高程模型（DEM）和实地调查进行了分析。提出了一种估算TRM引起的潮汐沉积速率的数学公式和潮汐盆地的选择策略。研究结果表明，水资源综合管理在区域生计方面取得了重大进展，如防洪能力、耕地面积、可耕地面积、种植密度和粮食安全。此外，在TRM上建立的技术事实将有助于规划者对该过程有生动的看法。
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.
