Publication: Groundwater Level Dynamics in Bengaluru City, India

Posted on Posted in Consultancy, GIS solutions, Mathematical Modelling, News, Urban planning

Groundwater accounts for half of Indian urban water use. However, little is known about its sustainability, because of inadequate monitoring and evaluation. We deployed a dense monitoring network in 154 locations in Bengaluru, India between 2015 and 2017. Groundwater levels collected at these locations were analyzed to understand the behavior of the city’s groundwater system. […]

Publication: A Framework for Assessment of Climate Change Impacts on Groundwater System Formations

Posted on Posted in GIS solutions, Mathematical Modelling, Uncategorized

In order to understand the impact of climate change on vegetation and soil on the groundwater system comprehensively, complex coupled models that require a series of estimated parameters were run in a distributed framework for a catchment. The simple and general approach used to investigate the potential impact of climate change on groundwater fluxes forces […]

Publication: A Spatio-Temporal Algorithm for Merging Soil Moisture from Active and Passive Microwave Remote Sensing

Posted on Posted in Agriculture, Algorithm Development, Disaster Management, Environment, Geospatial Modelling, GIS solutions, Mathematical Modelling, News, Satellite Remote Sensing, Validation of satellite retrieved variables, Water Resources

Currently the soil moisture is available either at coarse spatial scale from passive microwave remote sensing or at infrequent repeat time from active microwave remote sensing. A novel MAPSM algorithm is developed which merges Active and Passive microwave Soil Moisture to obtain a higher spatio-temporal soil moisture which is a prerequisite for various hydrological, agricultural and […]

Publication: Estimation of available water capacity components of two-layered soils

Posted on Posted in Agriculture, Algorithm Development, Mathematical Modelling, News, Water Resources

Characterization of the soil water reservoir is essential for modelling the interactions between crops and their environment. Current study utilizes the inversion of a crop model for estimating root zone properties. The approach has been evaluated over four crops (sunflower, sorghum, turmeric, maize) grown on different soils and several years in South India. The components of AWC […]

Publication: High Resolution Land Surface Geophysical Parameters Estimation from ALOS PALSAR data

Posted on Posted in Algorithm Development, Geospatial Modelling, GIS solutions, News, Satellite Remote Sensing, Validation of satellite retrieved variables

A satellite-only algorithm (which does not need ancillary data on soil surface roughness and vegetation) to retrieve soil moisture is tested over ambhas site (www.ambhas.com) in India. The satellite data used is L-band ALOS PALSAR which has all weather capability. The estimated soil moisture had a spatial resolution of 25 m capable of estimating crop […]
