Bank erosion is an inevitable vestige of past to evident fluvial dynamics in relation to its discharge and velocities and work-load in view of its load washed or unwashed. The central idea is best suited to study the case of River Mahananda alias Mahanadi within the Upper Mahananda River basin area having similar kind of attestation of facts. The present study needed extraction of satellite imageries of Landsat from USGS sites associated with its processing and ultimately to frame out the temporal scenes through NDVI technique to visualize if the forest cover is at all influenced by bank erosion or not or for specific scales whatever is the reality. The inference registered heavy scouring along the hugging banks with temporal avulsions and bed aggradation. The rates of change of foothill forest areas and variation of cultivable areas for a period of 30 years initiating from 1990 is addressed to study here.

The paper deals with the distribution of the genus Glossopteris and its fructifications in different Lower Gondwana formations of Talcher Coalfield of Odisha State. We demonstrate how this taxon appeared in this basin in the earliest Permian Talchir Formation and evolved and diversified through the Karharbari, Barakar, Barren Measures and lower part of Kamthi formations and ultimately vanished in the early Triassic in the upper part of Kamthi Formation. Amongst fifty-one species of the genus Glossopteris recorded in all, one species each has been found in the Talchir and upper part of Kamthi formations and two, sixteen and forty-seven species respectively are represented in Karharbari, Barakar and the lower part of Kamthi formations. Barren Measures Formation is devoid of any megaplant fossil. Similarly, out of twenty-seven taxa of fertile organs belonging to the Glossopteris, two each are found in the Talchir and Barakar formations respectively, whereas twenty-four are recorded from the lower part of Kamthi Formation. It is observed that Glossopteris is less diversified in Early Permian Karharbari Formation. However, it diversified and proliferated during Barakar and Late Permian lower part of Kamthi formations. Further, it shows declination in the Early Triassic upper part of Kamthi Formation. The study shows that the lower part of Kamthi Formation of Talcher Coalfield has the maximum diversity of Glossopteris (forty-seven species) among all the known localities of this formation exposed in Indian Gondwana. The existence of meagre Glossopteris species against many Gangamopteris species in the needle shale confirms its association with the lower floral zone of Talchir Formation instead of the upper floral zone established by previous workers in this basin. Very low diversity of Glossopteris in the upper part of Kamthi Formation of Talcher Basin demonstrates that this palaeogeographic area would have experienced more arid conditions in early–middle Triassic period as compared to the mellowing climatic conditions prevailing during the same time period in the Panchet Formation (=Upper Kamthi Formation) of other areas of Son–Mahanadi Basin and the Damodar Basin.

Abstract Development is said to be sustainable in respect of drought if the effect has been absorbed by the existing system. Occurrence of drought depends on physiographical, climatic factors and optimum utilization of available resources of the river basin. This study aims to evaluate the vulnerability and resilience of river basin systems for the identification of priority areas under drought susceptibility for three different river basins, namely Arpa, Kharun and Upper Seonath of Mahanadi river in central India, as a pilot area for this study. The study represents an approach to evaluate the drought susceptibility of river basins based on physiographical factors and anthropogenic activities. A model proposed for vulnerability assessment based on variables of exposure, sensitivity and adaptive capacity, and a geospatial database of basin characteristics contributing to vulnerability, was generated using remote sensing and a geographic information system. Multi-criteria decision analysis was done to evaluate the influence of river basin characteristics, population load and land-use/cover on drought susceptibility for assessing the drought vulnerability of the river basin and suggest the solution for the optimum utilization of natural resources according to the river basin characteristics. The result of this study demarcates the area in four categories of Extremely vulnerable, Moderately vulnerable, Vulnerable and Not vulnerable. On the analysis, only 3.86% of Upper Seonath is Not vulnerable, followed by Kharun basin having 15.59% as Not vulnerable area and 48.23% of the area of Arpa river basin identified as Not vulnerable. Arpa river basin is least affected by drought due to its lower population density and high coverage of forest and agriculture area.

Megaspores have been recorded from the Athgarh Formation of Mahanadi Basin. The megaspore assemblage comprises species of Banksisporites, Bacurnleres, Erlansonisporites, Minerisporites, Saccarisporites, Paxillitriletes, and seed structures referable to Spermatites. The megaspore assemblage has a preponderance of the genera Paxillitriletes and Minerisporites in association with other Early Cretaceous forms, and thus supports the age arrived at on the basis of megafloral data. Spore/pollen investigations had earlier revealed an age ranging between Upper Jurassic to Lower Cretaceous.

Palynological investigation of 483.00 m deep subsurface Permian sediments of borehole MSK–1, in Sithra–Kurekela Block of Mand Coalfield, revealed four distinct palynoassemblage zones. These palynoassemblages belong to Lower and Upper Barakar (Early Permian), Barren Measures and Raniganj (Late Permian) palynofloras of Indian Gondwana. The oldest Palynoassemblage–I, (Scheuringipollenites barakarensis) recorded between 483.60–309.00 m depths, shows dominance of non–striate bisaccate pollen grains chiefly ― Scheuringipollenites followed by Faunipollenites in association with Indotriradites, Dentatispora, Verrucosispora and Microbaculispora related to Lower Barakar palynoflora. Palynoassemblage–II, (Faunipollenites varius) recorded between 303.40–139.40 m depths, showing the dominance of Faunipollenitesin association with Scheuringipollenites, Striatopodocarpites, Brevitriletes, Horriditriletes and Striamonosaccites, indicates Upper Barakar palynoflora. Palynoassemblage–III, (Densipollenites indicus) recorded between 135.55 to 92.50 m depths, showing the prominence of enveloping monosaccate pollen (Densipollenites) in association with Faunipollenites, Microfoveolatispora, Striatopodocarpites and Verticipollenites, indicates Barren Measures palynoflora. Palynoassemblage–IV, (Densipollenites magnicorpus) recorded between 90.90–27.00 m depths, is characterized by the dominance of striate bisaccate pollen taxa chiefly Striatopodocarpites and Faunipollenites along with Densipollenites, Navalesporites, Distriatites, Hamiapollenites, Crescentipollenites and Guttulapollenites indicating late Permian (Raniganj) age. Raniganj palynoflora has been demarcated in lithologically designated Barren Measures Formation. This is the first report of Late Permian (Raniganj) palynoflora from Sithra–Kurekela area of this coalfield. The age correlation also gets support from comparative studies with similar palynoassemblages known from Indian Gondwana. Palynofloral evidences indicate the prevalence of warm and humid conditions. Dominance of gymnosperms represented by glossopterids, conifers and cordaites along with low percentage of trilete spores (filicopsids and sphenopsids) suggests that the sediments were deposited under fresh to brackish water environment.

Annotation:
Onset of monsoon for each year of the period from 1961 to 1986 over the Upper Mahanadi basin has been studied taking into consideration the sharp increase in water levels of the Hirakud reservoir. This study has shown that .there are positive and negative time-lags in the arrival of monsoon run off into the reservoir. It has been seen that positive time lags are due to antecedent condition of the basin before the onset of monsoon while negative time-lag appears to be due to pre-monsoon thunderstorm activity which causes reservoir levels to increase before the onset of monsoon. Attempt has been made to discuss all these cases briefly. It has been seen that on a majority of occasions monsoon runoff has reached the reservoir with a time-lag of 1 to 4 days.

The Korba Coalfield occupies the south-central part of Son-Mahanadi Master basin and is situated in the Korba and Bilaspur districts of Chhattisgarh State. With five open cast mines (Gevra, Dipika, Manikpur, Kusmunda and Laxman) spreading over 530 sq. kms, this coalfield is the biggest coal producing unit in India, however it was never explored for megafloral studies. Extensive investigations were recently conducted in this coalfield to discover the fossiliferous beds in the Lower Gondwana deposits and as a result a large number of plant fossils were recovered from these collieries and their extension sites belonging to the Barakar Formation. The complete flora includes 38 taxa, representing 13 genera of the orders Equisetales, Cordaitales and Glossopteridales. The order Glossopteridales is highly diversified with 34 taxa and the genus Glossopteris with 22 species dominates the flora followed by the genera Vertebraria, Sakoarota (equisetalean stems), Cordaites, Dictyopteridium, scale leaves of fertile organs, Gangamopteris, Noeggerathiopsis, Euryphyllum and Rubidgea. This is the first ever collection and record of any mega plant fossil from this coalfield. The groups Lycopodiales, Sphenophyllales, Filicales, Ginkgoales, Cycadales and Coniferales are completely absent in this area which shows that the area might not be adequately cool and humid to facilitate the growth of these shade loving under-story plants. The genus Cordaites, which is a northern hemisphere taxon has been reported along with Glossopteris floral elements. An equisetalean genus Sakoarota, described from Madagascar has been reported for the first time from the Indian Gondwana. The genus Gangamopteris comprising six species, viz. G. cyclopteroides, G. cyclopteroides var. subauriculata, G. angustifolia, G. rajaensis, G. clarkeana and Gangamopteris sp. has been systematically described and discussed in this paper. The occurrence of Rubidgea, Euryphyllum, Noeggerathiopsis, Cordaites and Gangamopteris along with Glossopteris is indicative of the presence of Karharbari sediments (Early Permian=Lower Artinskian) in the lower part of the Barakar Formation exposed in the Gevra and Dipika collieries. The recovered plant assemblage indicates an Early Permian age, Lower Artinskian (Early Barakar) in the case of the Gevra and Dipika collieries and Upper Artinskian (Late Barakar) for the Manikpur, Kusmunda and Laxman collieries.
