India houses 5334 large dams in function (2329 numbers before 1980) and 411 dams are in pipeline. The Rengali dam, functioned from 1984, that traps 50% of the total sediment load of the Brahmani River continues to thwart the growth and buffering of the Brahmani delta. Remote sensing (RS) and Geographical Information System (GIS) have emerged as powerful tools to create spatial inventory on Hydro-Bio-geo resources and the state of the environment. The RS/GIS and process-based modelling employed in spatial and dynamic assessment of loss in live storage of the reservoir by developing contour, aspect and slope map by using data received from LANDSAT sources. The sedimentation of the Rengali reservoir (functional from 1984) studied for three decades 1990-20...

The inlets are maintained by discharges of inflowing streams during monsoon and by tides and ebb tides during non-monsoon. Imbalance in ingress and egress of sediment due to their continuous exchange between sea and the lagoon causes sedimentation of lagoon. Varying inflow, littoral drift and such other factors influence sedimentation. It results shifting mouths (inlets) continuously. Some mouths closed and some opened at various locations of the spits of the lagoon in course of time. This governs the inflow and the outflow characteristics and hence the salinity. A barrage at Naraj on Kathajodi, a major distributary of the river Mohanadi, and an artificial channel connecting the mouth of the Lagoon from Magarmunha to Bay of Bengal were provided to regulate the inflow. This phenomenon has been s...

The ascribing causes are fierce wind, torrential rain, and storm surge inundations. The sea surface temperature (>270C), relative humidity, wind shear, Coriolis force, cyclonic disturbances, warm oceanic current, easterly trade wind, Indian Ocean Dipole, and upper air cyclonic circulation. Odisha receives a lion's share of the slams of cyclones of the Bay of Bengal which is shattering its coastal inhabitants and the ecosystem. The cyclone data of the India Meteorological Department from 1891 to 2022are analyzed statistically. The categorization, naming, and cause of slam of cyclonic disturbances in the Bay of Bengal particularly along the Odisha coast are debated in the present study. The favorable geological stratification, meteorological players, and coastal features of the Odisha coast are discussed. The trends in landfall of various types of cyclones and the storms that shall brew and grow over BoB fabric from 1980 to 2020 have been using a machine-learning model. There is a decrease in cyclogenesis frequency but an increase in amplitude, intensity, and severity is the present trend along with a southerly shift of landfall along the east coast. The changes in the coastal corridor, the discrete Eastern Ghats belt, and its seaward retro gradation are the reason that the southwest monsoon brings with it high wind shear, which has allowed the cyclones to slam the Odisha coast instead of the Gangetic coast and Godavari region.

The present study investigates the systematic unveiling of the cachet of past Chilika by scientific searches, and historical sneezes. The palynological, radiocarbon dating, paleo sediment, and phenology records from various searches and ground realities are correlated. The existing proxies are available in past histories and archeological findings. The remains of vegetation are compared with past mangroves, inland taxa, strand lines, and the tidal Inlet (TIs). They are interrelated with existing Survey of India (SoI) maps of 1930, 1963, and 1983, with GIS maps of 2022 after mosaicking, and georeferencing. The warm and dry periods, weak ISMR, LIA, anthropogenic interventions in the adjoint hydraulic system, regional mean sea level (RMSL) changes, and the strand line shifts, have made the BoB retrogress or transgress and transformed the coastal landform/ vegetation pattern since 1000YBP. The loss of maritime activity, mangrove losses, lagoon characteristics changes, and tidal inlet positioning has affected the lagoon's salinity and ecosystem. The unbalanced sedimentary budget and extreme climates have deteriorated the Lagoon's eco-health leaving today the fishing and tourism uses only. Consequently, lagoon users, especially fisherfolks, are marginalized, socio-politically exploited, and economically retrograded. Sustainable Development Goals (SDGs) 1,2, 8, 13, to 15 must be well attended to augment the flora, fauna, environment, and socioeconomic status of the lagoon users.

The destruction depends upon the frequency, intensity, place of formation, life span in Bay, SST, ENSO, El Nino Modoki, Indian Ocean Dipole, boreal summer atmospheric phenomena, Madden–Julian oscillation and the climatology of India’s mainland. The effective management of these vulnerable storms can reduce fatalities, degradation to environment and socio-economic consequences. The investigation to decadal trend of pre-monsoon bay disturbances for last 129 years reveals that the decadal distributions of cyclonic disturbances in BOB were irregular. From last 30 years pre-monsoon landfall data (1990 to 2019) divulges that frequencies of CS in BOB are increasing during La-Nina Modoki years than normal La-Nina years. The frequencies of SCS increase during warm, strong La-Nina years than La-Nina Modoki year...

It is a product of naturally available materials with the some chemical processes that generates solid waste, and GHG gases from the factory that pollutes soil, air and water. The demand for cement is gradually rising due to urbanization, industrialization and modernizations, and augmented it is short supply. The sustainable partial or fully replaced products used for replacement of cement is to be invented to obtain from recycled wastes and must be non-pollutant of atmosphere and ecofriendly. Researches must be made with the low cost waste materials like red mud, GGBS, fly ash and many others. The present research is the ousting element sugarcane bagasse ash (SCBA) as a partial replacement of cement. To improve the tensile properties of concrete, attempts are made to add small closely space out and evenly discrete natural organic Siyalifibre with the SCBA concrete which can provide better properties t...

The uplands between the distributaries constitute the West of Daya, Daya-Bhargovi, Bhargovi-Kushabhadra and the coastal watersheds. The major water shed is the upland bounded by the rivers Daya and Bhargovi which decant to the Chilika lagoon which has unique ecosystem and hotspot biodiversity. The lagoon receives 70-80% of its inland flow from the Mahanadi system. About 6-8% of total sediment of the total Mahanadi system debouches into the lagoon threating the lagoon to be a depleted wetland in future. The sediment due to reel and the gully erosion of the local catchments plays important role in soil management. To study the average annual loss of soil of the watersheds, the rainfall erodent factor (R), soil erosion factor (K), basin length (L), gradient (S), crop type coefficient (Cc), tilling practice coefficient (Cp) and support practice factor (P) have been derived using rainfall data, satellite imageries and agriculture statistics of the area. The West of Daya watershed shows higher soil erosion rate than others. The average erosion rate of the south Mahanadi delta is estimated as 8.347 MT/ha/yr. and the coastal sandy area as 0.393 MT/ha/yr. Management strategies for reducing erosion rate are check dams, stone terraces, contour ploughing and cultivating salinity tolerant crops by proper catchment treatment plan for the area.

The coastal state has immense rich biodiversity and possesses a rich ecosystem. The congregated bionetworks (marine, brackish, estuarine, inland and hilly) have different uniqueness in flora, fauna, aqua-fauna. Odisha, along the east coast of India is running parallel for 480Km to the Bay of Bengal including the largest brackish water lagoon Chilika and vast dry rainforests of the Eastern Ghats. The state has an area of about 155707 Km 2 , forest area recorded 51345Km 2 (31.38%) and home to about 7,000 plant species including 120 Orchids, 63 varieties of Mangrove trees constituting the state as second largest mangrove ecosystem in India. Many of the ethnic medicinal plants of the state which are not prioritized in the National Ayush Mission list have been investigated. The enumeration and preservation planning of endemic and threatened species of flora, fauna, avifauna of Odisha reveals that the coastal ecosystem is richer than inland ecosystem of Odisha.

Asia’s largest shallow brackish water lagoon, the Chilika housed over about 1000km, behind 64.3km barrier spit with multiple tidal inlets to Bay of Bengal. It is sinking and shrinking due to rapid dimensional diminution, environmental degradation, sedimentation, salinity depletion, phytoplankton invasion. Present study envisages the elementary morphology, formation mechanism, sediment transport, and dynamic performance of tidal inlets and the lagoon by applying GIS methodology between the year 1930 and 2017 including its local catchment land use changes within the lagoon and associated south Mahanadi delta. Under vulnerability, the Original Research Article Mishra et al.; ARRB, 36(2): ...

South Mahanadi deltaic branches i.e. Daya and Bhargavi terminate at the southwest swamps of the Lagoon. The annual average salinity of the lake was depleted from 22.31ppt (1957-58) to 8.5 ppt. (1999-2000) as the mixing process of saline and fresh water was influenced from 1995. Trepidation of conversion of Chilika to a atrophied fresh water lake due to blooming population and their hydrologic interventions like Kolleru lake in (India), Aral Lake (Uzbekistan) was apprehended by 1950’s and was alarming by 1999 when the shallow inlet(s) shifted extreme north. The shallow mud flats of lean salinity were reclaimed further for agriculture. The ecology and biodiversity degraded with substantial pecuniary loss to the lagoon dependents. Anthropogenic interventions like, Hirakud dam (1956), dredging of Sipakuda Inlet (2000), Naraj barrage at delta head (2004), Gobardhanpur barrages (1998) and Gabkund cut with...

The 2853km long east coast has huge continental self of 22411sqkm. Major east flowing rivers the Mahanadi, the Godavari, the Krishna and the Cauvery have huge sedimentary deposits in the offshore which are either subaqueous or sub aerial and developing estuaries or sand bars along the coastal interface. Geospatially cyclones, Tsunami, meteorological and geological extremes are conducive for change of the coast line. Continuous formations of bars and spits along the shore front have changed the configuration of river outlets. Sediment deficit from inland rivers, formation of lateral parallel channels along offshore have been observed in the in the river mouth for last 10 to 12 years. In the present study, the satellite imageries are used to establish the reformation in the river outlets. The changes initiated by bar formation bendingof river mouths to north are prominent from the Subarnarekha to Godavari mouth. Corioli...
