The outputs of four CMIP6 Global Climate Models have been downscaled using the statistical downscaling method to the basin level. A comparative analysis for the accuracy achieved in the bias correction for the combination of GCM and downscaling method has been performed before utilising the downscaled weather parameters for hydrological study. The MIROC6 and ACCESS-CM2 were found best for the simulation of precipitation and temperature, respectively. The Distribution Mapping and Variance Scaling methods have shown better accuracy w.r.t other statistical methods. The impact of climate change has been found significant since the temperature has been observed to be increased by 3.16 °C by the end of 2060; meanwhile, there is an average decrease of 9.2% in the annual rainfall from the baseline. The peak runoff has increased while there is a significant decrease in t...

The study attempts to decipher the relative time sequencing of the morphotectonic events based on certain assumptions. Badlands are essentially erosive systems that result due to some critical combination of multiple factors such as a change in rainfall pattern, deterioration of soil properties, overgrazing history, changes in land use and land cover, changes in groundwater conditions, etc. and may or not have additional impetus due to tectonic events in their growth. The thin layer of sediments with variable thickness showing active badlands in the study area overlies the southernmost part of the Faizabad Ridge, which has a subsurface horst formation. With the assistance of remote sensing and GIS, numerous morphotectonic parameters have been determined. The result shows that the less elongated (Re = 0.7) shape of the Mandakini River watershed, Hypsometric integral (HI = 0.48), and basin shape index (Bs = 1.6), and the windy channel are indicative of moderately active tectonism in the watershed. Although the watershed is more or less symmetrical in some parts, the basin asymmetry factor (AF) is 55.24, which again indicates there is a partial impact of low active tectonics on the watershed under the study area. Sub-watersheds at the third order-level show significant variations of these morphotectonic indicator parameters observed through the sub-watersheds of the study area. In this regard, it is also of significant consideration that the spatial orientations of several sub-watershed show strong discords from the general orientations of the rest of the sub-watersheds at the third-order level, and as such, they occur as morphometric 'inliers' in the current scheme of the current drainage processes. Continuous, uninterrupted geomorphic processes cannot account for this discord, and in the absence of any significant anthropogenic interference, these could only be correlated to aggravating impacts of neotectonics interventions. On the basis of significant values of the morphometric parameters indicative of neotectonism and spatial discord of the sub-watershed, a division of zones has been attempted here, showing a degree of neotectonic interference during the sustained erosive phase of badlands formations. The values are found to be ranging from High Tectonic to Low tectonic signatures of different tectonic activity phases. The tectonic events have been classified in the GIS environment, and the spatial signatures of tectonic events, namely the High Tectonic Activity Phase (HTAP), Moderate Tectonic Activity Phase (MTAP), and Low Tectonic Activity Phase (LTAP), have been deciphered. Finally, the present work offers assumptions for sequencing the events.

Following investigations were made on the soil samples collected from the field: i) grain size distribution ii) various physicochemical properties and nutrient content of the soil. The clay minerals were detected and identified with the X-ray diffraction (XRD), Fourier transform infrared (FTIR), and High-Resolution Scanning Electron Microscopy (HRSEM). The spatial maps of all these parameters were prepared in a GIS environment, and overlay analysis was performed. The results

In this context, it leads to conceptualization that the cause of badland formation is not merely topographical but should be related to changes in the intrinsic properties of soils. There is a lack of understanding as to the formative role of physico‐chemical characteristics of soils in the formation of badlands. The objective of our study is to determine such critical physico‐chemical characteristics of soils that are responsible for the onset of a self‐aggravating erosive network of badlands by undertaking a case‐study of part of the Mandakini River watershed, Chitrakoot, India. Standard IS codes were followed in determining these properties. These soils have a silt‐loam texture with high bulk density. Depletion of clays lowered Atterberg limits which consequently r...

India. The striking features observed behind the high rising south facing ridge was the presence of linear valley dividing the ridge from the Damoh plateau. The setup itself presents an excellent site for tectono-morphic studies. Moreover, the valley is narrow and tight and its base is high up by more than 50 m. from the plain of Hiran. Thus the whole setup offers an opportunity for storage of water with an advantage of water head with respect to the Hiran plain. Topographic maps on 1:50000 scale were utilized to delineate the drainage system, thus to identify precisely water divides using Geographic Information System (GIS). Morphometric parameters were determined for Hiran basin and principal component analysis was carried out. The result...

This study utilizes the morphometric methods with the help of remote sensing data in a GIS environment to determine the characteristics of the badlands of Mandakini River watershed and their interpretation to explore the factors responsible for the formation of the typical landforms. Objective interpretation of morphometric data of badlands with the help of statistical Pearson's correlation coefficient (PCC) and dendrogram cluster may be made to emphasize the controlling factors. The morphometric parameters like the total number of streams (Nu), bifurcation ratio (Rb), drainage density (Dd), drainage frequency (Fs), drainage texture (Dt), and infiltration number (If) and their correlation in the study area plays a significant role in the advancement of rills and gullies. In the present area, the total number of streams (Nu) is very significantly related with the lengths of the first-order (L1), the second-order (L2), and the third-order streams (L3) along with the total stream length of all orders (Lu) in the third-order and the fourth-order sub-watersheds. Bifurcation ratio (Rb) is strongly correlated with L1, L2, L3, L4, and drainage texture (Dt) in the fourth-order sub-watershed. These correlations insinuate a tectonic influence in the basin and show an ultrafine drainage texture that ultimately forms badland topography. The relation between Dd-Lg-C-If-Rn produces a self-enhancing system of badland development, which promotes erosion in the area under study. These correlations provide a well-figured observation of the sub-watershed that, due to the increase in infiltration number (If), the drainage density (Dd) also increases, which leads to enhancement of channel cutting and erosion rates (low Lg and C value). This correlation coefficient of Rn is moderately low, indicating a single storey type of badlands. The badlands seem to have formed owing to setting up of self-enhancing erosive system on paleo wetlands, as evidenced by the presence of calcretes. Calcretes have been related to the presence of wetlands' conditions. These have been related to fall in water levels, therefore, indicating much higher water levels nearly close to ground surfaces before setting up badlands conditions. Thus, the badlands which have shallow calcretes horizons can be said to have been wetlands in the past.

It is a growing problem especially in areas of agricultural activity where soil erosion not only leads to de-creased agricultural productivity but also reduces water availability. This leads to drastic degradation of the agricultural lands. So there is a need to take up conservation and management measures which can be applied to check further soil erosion. Universal Soil Loss Equation (USLE) is the most popular empirically based model used globally for erosion prediction and control. Remote sensing and GIS techniques have become valuable tools for the digitization of the input data and genereation of maps. In the present study, RUSLE model has been adopted to estimate the soil erosion in the Khajuri watershed of Uttar Pradesh, India. This model involves calculation of parameters including runoff-rainfall erosivity factor (R), soil erodability Factor (K), topographic factor (LS), cropping management factor (C), ...

This paper revisits the diminishing urban and suburban wetlands of Jabalpur (Madhya Pradesh, India), and elucidates their changing fate with the socio-dynamics through the past one thousand years. Considering geomorphology, lithology, structural geology and water table depth, this paper presents a useful technique which can be confidently applied in the reconstruction of the erstwhile wetlands which lie buried beneath the present day urban spread. It comprises hydro-geomorphic and hydro-geological facts with fragmented evidence of history in order to reconstruct a consistent script of events over the past millennium in the study area. This work should find wide applicability in recognizing other such townships where drainage network changed due to natural as well as anthropogenic conditions in the recent past. Such places have implicit risk of pollution vulnera...

Still there is no concerned plan to relocate people en mass that lose their lands and place on the onset of the mega projects, viz. dams, thermal power plants etc. This paper introduces the concept of Rehabilitation watersheds for such sufferers of development. This team has made surveys of people who were forced to leave their places to live a deprived life for the sake of development of the State. Concept of Rehabilitation watershed focuses on a systematic and sustainable development of fallow lands, deteriorated lands and ravine lands through social agencies. Such lands should be identified throughout the country and be developed by systems planning such that as and when required these watersheds, well developed and turned productive wit...

Samples of water were collected from various localities such as Narmada and Pariyat water supply system, various ghats of Narmada river, various tals and tanks, main drains of the city such as Omti nala and Moti nala and were analyzed for pH, electrical conductivity, temperature, dissolved oxygen, five days Biological oxygen demand , fecal coliform , turbidity, total solids, nitrates and phosphates.Water quality indices "WQI" developed in 1970 by the U.S. National sanitation foundation were calculated for these water samples. The results conclude that the water quality of water supply systems, various ghats of Narmada River is of medium quality and can be used for domestic use after suitable treatment. The water quality of various tanks and drains falls in the range of bad quality w...

It belongs to the northern part of the CITZ (Central Indian Tectonic Zones). The selected area has morphological features in strong physical association with Narmada North Fault and related tectonic association such as linearity of the valley in question and other lineaments. The present study has been made in GIS environment and layers of geological units , geomorphology, land use and CN values have been produced. Water balance approach can be resorted to for approximate estimation of surface run-off and groundwater discharge of the linear valley. The Rainfall-Run-off analysis reveals that there is adequate rainfall in this region and it can be...

The trio of remote sensing, GIS, and morphometric analysis gives the best possible results in investigating, supervising, and understanding the basin. The present study comprises a detailed study of morphometric parameters in a badland affected subwatershed of the Mandakini River. The sub-watershed is located in the northern foot slope of Vindhyan mountain range. The area consists of many structural and denudational hills, pediment, and pediplain complexes. Geologically soft sedimentary rocks are in the majority in this terrain and the area comprises a diverse range of gullies, in terms of shape and size. The intensity of the study is both macro and micro watershed level (up to the third and fourth sub-watershed level). The analysis is mostly based on derived parameters such as bifurcation ratio (Rb), drainage density (Dt), stream frequency (Fs), drainage texture (Dt), length of overland flow (Lg), and constant of channel maintenance (C), shape parameters such as circularity Ratio (Rc), elongation ratio (Re), form factor (Rf), and in relief parameter ruggedness number (Rn) and dissection index (Di). The analysis shows that low infiltration rate, i.e., a higher value of infiltration number (70.0), triggers high runoff and hence increases drainage density (4.5), drainage frequency (15.16), and drainage texture (25.23) and ultimately from an erosional setup in the sub-watershed and it is gradually deforming the land into a rugged terrain.
