Trend analysis and variability of satellite-based soil moisture data for the Lower Bhavani basin, Tamil Nadu using Google Earth Engine
نویسندگان
چکیده
Soil moisture is a significant hydrological component that dynamic in nature. The variation soil the basin scale would affect vegetation, ecology and environment. trend analysis aids providing of over basin. present study aimed to analyse Lower Bhavani basin, Tamil Nadu from 2003-2022. Satellite-based Global Land Data Assimilation System (GLDAS) data was extracted Google Earth Engine (GEE) platform period time. highest lowest observed during monsoon summer months its percentage studied. Using Man-Kendall test Sen’s slope, calculated for two decades (2003-2012 2013-2022). In 2003-2012, an increasing winter (October February); 2013-2022, both February) seasons (June September). remaining season did not follow any trend, there no decreasing moisture. will help monitor manage environmental system across

Variability of Soil Moisture in the Walawe River Basin: A Case Study in Sri Lanka Using Low-Resolution Satellite Data
Limited availability of freshwater and increasing demand for food require careful management of available resources. However, information on water utilization within river basins is often inadequate for comprehensive water management. Therefore, researchers are developing new tools and methodologies to overcome these data problems. A major concern for land use planning is the identification of ...
متن کاملUse of Satellite Data for Soil Moisture Analysis at Ecmwf
Land surface processes and their initialization are of crucial importance to address the challenge of seamless (from weather to seasonal) Numerical Weather Prediction (NWP). In particular it has been found that soil moisture influences the landatmosphere exchange processes on all relevant time scales. It is therefore expected to be of high interest for NWP applications to assimilate new satelli...

A new approach to downscaling soil moisture forecasts from the seasonal ensemble prediction forecasting system of the ECMWF (European Centre for Medium-Range Weather Forecasts) is presented in this study. Soil moisture forecasts from this system are rarely used nowadays, although they could provide valuable information. Weaknesses of the model soil scheme in forecasting soil water content and t...

Wetlands are dynamic and complex aquatic ecosystems that play an important role in the survival of many plant and animal species. This study modeled the spatio-temporal changes of the Arak Meighan wetland during 1985–2020 using the multi-temporal Landsat images. In doing so, the applicability of different satellite-derived indexes including NDVI, NDWI, MNDWI, AWEIsh , AWEInsh , and WRI was inve...
