Sustainable groundwater management requires an accurate characterization of aquifer-storage change over time. This process begins with analysis historical water levels at observation wells. However, water-level records can be sparse, particularly in developing areas. To address this problem, we developed imputation method to approximate missing monthly averaged groundwater-level observations in...

Severe meteorological drought is generally considered to lead crop damage and loss. In this study, we created a new standard value by averaging the values distributed in middle 30–70% instead of traditional mean value, proposed index calculation method named Normalized Indices (NI) for monitoring after normalized processing. The TRMM-derived precipitation data, GLDAS-derived soil moisture MODIS...

This study investigates the performance of TU Wien soil moisture retrieval (TUW-SMR) algorithm by adapting strength vegetation correction. The semiempirical change detection method TUW-SMR exploits multiangle backscatter observations from spaceborne fan-beam scatterometer systems in order to derive surface information expressed degree saturation. parameterization is controlled dry and wet cross...

Drought affects a region’s economy intensively and its severity is based on the level of infrastructure present in affected region. Therefore, it important not only to reflect conventional environmental properties drought, but also target region for adequate assessment mitigation. Various drought indices are available interpret distinctive meteorological, agricultural, hydrological characterist...

GRACE spherical harmonics are well-adapted for representation of hydrological signals in river drainage basins large size such as the Amazon or Mississippi basins. However, when one needs to study smaller basins, comes up against low spatial resolution solutions harmonics. To overcome this limitation, we propose a new approach based on Slepian functions which can reduce energy loss by integrati...

Mango is widely known as a popular fruit in South Asia, including Bangladesh. The country significant producer of different local and exotic varieties mangoes geographic locations. Therefore, study maturity at diverse locations climatic conditions becomes critical for sustainable mango production. In responding to this need, evaluates the variability few selected commercial (Mangifera indica L....

Clarifying the evolution pattern of groundwater storage (GWS) is crucial for exploring amount available water resources at a regional or basin scale. Currently, Northeast China have been extensively exploited, but only limited studies assessed extent GWS depletion and its driving mechanisms. In this study, anomaly (GWSA) in black soil region was explored based on Gravity Recovery Climate Experi...

The Limpopo River basin (LRB) is known for its vulnerability to floods, high rates of evapotranspiration, and droughts that cause significant losses the local community. present study aimed perform simulations flood events occurring in two Mozambican sub-basins LRB, namely Chókwè Xai-Xai from 2000 2015 with TOPography-based hydrological MODEL (TOPMODEL) satellite remote sensing data. As input T...

Groundwater is a primary freshwater resource for human consumption and an essential source industry agriculture. Therefore, understanding its spatial temporal trends drivers crucial governments to take appropriate measures manage water resources. This paper uses Gravity Recovery Climate Experiment (GRACE) satellite data the Global Land Data Assimilation System (GLDAS) derive groundwater storage...

This paper deals with the variability of Normalized Difference Vegetation Index (NDVI) and its association with rain rate and total evapotranspiration over Bangladesh during the period of 2003-2011 using MODerate-resolution Imaging Spectroradiometer (MODIS), Tropical Rainfall Measuring Mission (TRMM) and Global Land Assimilation System (GLDAS) data. NDVI shows higher concentration in eastern pa...
