Abstract Intensive irrigation in northwest India has led to growing concerns over the sustainability of current and future groundwater abstraction. Environmental tracers measurements residence times can help quantify renewal processes. Results from 16 paired locations show interquartile ranges for shallow alluvial (8–50 m deep) be 1–50 years significantly less than those deeper (76–160 at 40–170 years. The widespread occurrence modern deep (>60% sites had >10% recharge) suggests that...
The fluoride contamination in drinking water is already gone to the alarming level and it needs immediate involvement attention of all people solve this problem. Fluoride problem higher hard rock terrains worldwide Madurai such type region. Totally 54 samples were collected from district Tamilnadu with respect lithology. analysed for major cations anions using standard procedures. concentration noted Charnockite types northern part study area. 20 % are below 0.5 ppm 6 above 1.5 exceeding...
In recent decades, due to rapid increases in water demand and greater usage of for irrigation from surface canals, waterlogging problems have been created the southwest zone Punjab, coupled with a stagnation saline formation salinity ingression. To understand these issues, present study has conducted three districts (Muktsar, Fazilka, Faridkot) Punjab root cause. this end, groundwater samples were collected 142 piezometers developed at 40 sites. Electrical conductivity (EC) observations...
Partitioning of evapotranspiration (ET) is a fundamental challenge in ecohydrological research, critical for advancing our understanding the soil-plant-atmosphere continuum. This study investigates ET partitioning spring wheat crops grown at an experimental plot IIT Kanpur using stable isotopes oxygen and hydrogen. By exploiting distinct isotopic signatures evaporation (E) transpiration (T), contributions these processes to total were quantified. The compositions E determined Keeling...
Bist-Doab, Punjab, northwest India. Water isotopes and specific electrical conductivity (SEC) are used in this paper to investigate groundwater recharge sources processes a catchment with history of high abstraction for irrigation canal irrigation. High frequency (every 10 days) samples water stable isotope analysis (δ18O δ2H) were sampled from dense network shallow (<50 m) deep (>100 hand pumps tube wells northern Punjab between 2009 2014. The study indicates that is dominated by meteoric...
