Kumar et al 2018 explored this analysis using open-access earth observation datasets in the drought-affected part of Bundelkhand, India. Mahmoud and Alazba (2015) and Kumar et al 2014 respectively demonstrated the morphometric and geophysical analyses of major rainwater harvesting basins in Saudi Arabia and six sub-watersheds in the central zone of Narmada river in India.…”

Drainages are pulses which in turn help us to understand the ongoing process in the hill ecosystem. The Kalrayan hill is known for its dissected terrain condition, rich biological diversity and depletion of natural resources. Therefore, a study on quantitative geomorphometry was carried out in the Kalrayan Hills, Eastern Ghats, Tamil Nadu, using Indian remote sensing 1D LISSIII satellite data. The study area was divided into 36 watersheds and total area is 1158.4 km 2 . It covers the upper part of Vellar basin. The linear, aerial and relief aspects and different morphometric parameters such as stream length, bifurcation ratio, drainage density, stream frequency, drainage texture, relief ratio, basin shape, form factor, circularity ratio, elongation ratio and length of overland flow were computed using standard methods, formulae and geo-spatial technologies. Based on the present drainage morphometric study, it is inferred that the watersheds 3, 4, 6, 9, 11, 12, 15, 17, 18, 19, 20, 22, 24, 27, 32, 33, 34 and 36 are active with reference to geological processes, mean denudational rate, peak discharge, mean annual run off, dominant watershed process and sediment yield per unit area. Multi-criteria analysis is performed to determine the drainage architecture and hydrogeological processes occurring in the present hill area.

“…However, it is still unclear how the anthropogenic and natural factors drive the change in the fluxes and storages of water, and associated groundwater quality. Consequently, a linked understanding of surface water and groundwater quality over space and time is critical for the assessment and management of such vital resources and ecosystems services, particularly in arid and semi-arid regions [4,15,16]. Since domestic, industrial, agricultural, and other uses can affect the chemical and physical characteristics of groundwater [10,12].…”

Groundwater is a vital resource for human welfare. However, due to various factors, groundwater pollution is one of the main environmental concerns facing. Yet, it is challenging to simulate groundwater quality dynamics due to the insufficient representation of nutrient percolation processes in the soil and Water Assessment Tool model. The objectives of this study were extending the SWAT module to predict groundwater quality. The results proved a linear relationship between observed and calculated groundwater quality considering No3 and TDS with R2, NSE and PBIAS values in the satisfied ranges, albeit underestimation and overestimation were observed due to limited data availability. These results highlight that nitrate and TDS concentrations and variability in groundwater may used as a tool in surface water quality that have to be assumed for designing adaptive management scenarios. Hence, extended SWAT model could be a powerful tool for future regional to global scale modelling of nutrient loads supporting effective surface and groundwater management.
