“…Knowing the interrelationships among different historical changes, human interventions, climate variability and corresponding trends of hydrology helps in addressing future water management approaches (Johns et al ; Black ). Moreover, we need to keep in mind the increasing influence of climate change, population growth, and urbanization taking place in the region (Choudhury et al ; Islam et al ).…”

The Ganges Delta in Bangladesh is an example of water‐related catastrophes in a major rural river basin where limitations in quantity, quality, and timing of available water are producing disastrous conditions. Water availability limitations are modifying the hydrologic characteristics especially when water allocation is controlled from the upstream Farakka Barrage. This study presents the changes and consequences in the hydrologic regime due to climate‐ and human‐induced stresses. Flow duration curves (FDCs), rainfall elasticity, and temperature sensitivity were used to assess the pre‐ and post‐barrage water flow patterns. Hydrologic and climate indices were computed to provide insight on hydro‐climatic variability and trend. Significant increases in temperature, evapotranspiration, hot days, heating, and cooling degree days indicate the region is heading toward a warmer climate. Moreover, increase in high‐intensity rainfall of short duration is making the region prone to extreme floods. FDCs depict a large reduction in river flows between pre‐ and post‐barrage periods, resulting in lower water storage capacity. The reduction in freshwater flow increased the extent and intensity of salinity intrusion. This freshwater scarcity is reducing livelihood options considerably and indirectly forcing population migration from the delta region. Understanding the causes and directions of hydrologic changes is essential to formulate improve water resources management in the region.

Coastal wetlands are a vital resource for the sustainable development of coastal areas. This paper presents a comprehensive monitoring of coastal wetland resources and their evolution in the northern region of Rizhao using multi-period remote sensing data and field investigations. The results show that as of the 2020s, wetland resources in northern Rizhao include subtidal wetlands, artificial wetlands, and intertidal wetlands, accounting for 38.5%, 34.2%, and 26.7% of the total wetland resources, respectively. Over the past 35 years, the evolution of wetlands has been divided into two stages according to the impact of human activities. Before 2000, the wetland area expanded rapidly due to beach aquaculture development. Subsequently, after 2000, the beach wetland area experienced a decline, whereas the landscape wetland area increased. The reason for the change in the wetland area in the later stage was the artificial change in wetland type and beach erosion. By 2020, coastal erosion gradually became the main factor driving the change in wetlands. Therefore, strategies and measures aimed at promoting natural beach growth should be implemented by regulating coastal engineering activities.
