Wetland dynamics research primarily concentrates on individual wetland’s loss or gain of area where landscape specific approach is majorly ignored. While the fate of floodplain wetlands depends largely on the actions of the parent rivers such as increased flow, channel migration path, flooding events, channel cut-offs and others that are rather episodic in nature, so the overall situation may not be defined by the loss or gain of any specific wetland. Therefore, instead of using individual wetland-specific strategies if landscape-specific approaches are adopted, it might be possible to better interpret the wetland scenario. From this perspective, the floodplain wetland dynamics of the Diara region which is an active floodplain region of River Ganga has been assessed in three key dimensions like spatial, hydrological, and landscape ecological. Centroid method, hydro-period analysis, water presence, threshold dependent NDWI-NDVI are the key methods used for spatial and hydrological dynamics. A new method of Mean NDWI-NDVI Depth (MNND) has been introduced to measure the hydrological change in the wetlands. Few major landscape ecological metrics have been calculated using FRAGSTATS and lastly, the forest fragmentation rules are adopted to divide the wetland landscape into patch, edge, perforated and core areas. The result shows that wetland dynamics are very much unpredictable and strongly influenced by the behaviour of River Ganga. The wetland area has significantly gone up to 12095.37 ha in 2011 from 6795.9 ha in 1991 due to massive flood of 2010 and again it has gone down to 5725.35 ha in 2019. In 2019 the wetland centroid location has moved 2.14 km away from 1991′s centroid location in the opposite direction where River Ganga exists. Most of the wetlands are here heavily fragmented into smaller patches that results into the presence of only 10% core wetlands. Thus the vast portion of the floodplain wetlands can be degraded at any time due to hydrological instability, severe fragmentation and over-dependence on episodic events like floods.

湿地动力学研究主要集中在单个湿地的面积减少或增加，而这些地区的景观特定方法被忽略了。漫滩平原湿地的命运在很大程度上取决于母河流域的活动，例如流量增加，河道迁移路径，洪水事件，河道截断以及其他本质上是比较偶发的事件，因此总体状况可能无法由上游河流来定义。任何特定湿地的损失或增加。因此，如果采用特定于景观的方法，而不是使用针对特定湿地的策略，则可能可以更好地解释湿地的情况。从这个角度来看，Diara地区是恒河的活跃洪泛区，而该地区的洪泛区湿地动态已从空间，水文和景观生态三个主要方面进行了评估。质心法，水文周期分析，水存在，与阈值有关的NDWI-NDVI是用于空间和水文动力学的关键方法。引入了一种新的平均NDWI-NDVI深度（MNND）方法来测量湿地的水文变化。很少使用FRAGSTATS计算主要景观生态指标，最后，采用森林破碎规则将湿地景观分为斑块，边缘，穿孔和核心区域。结果表明，湿地动态非常难以预测，并且受恒河的行为强烈影响。由于2010年发生大规模洪灾，2011年湿地面积从1991年的6795.9公顷显着增加到了12095.37公顷，并且在2010年再次下降到5725.35公顷。2019年，湿地重心位置已移动2。与1991年质心位置相距14公里，与恒河存在的方向相反。此处大多数湿地都严重分散成较小的斑块，导致仅10％的核心湿地存在。因此，由于水文不稳定，严重的支离破碎和对洪水等突发事件的过度依赖，洪泛区湿地的大部分地区随时可能退化。
