spatial and temporal zoning of groundwater electrical conductivity and total dissolved solids in guilan plain
in recent years, the groundwater resources in guilan province have played an important role in irrigating paddy fields. the goal of this study was to evaluate temporal and spatial variations of groundwater quality in a 4-year period using ordinal kriging. water samples for this study were collected from 130 wells across guilan province, in september and march from 2003 to 2006. maps of ec and ...
متن کاملModeling of qualitative parameters (Electrical conductivity and total dissolved solids) of Karun river at Mollasani, Ahvaz and Farsiat stations using data mining methods
Background and Objective: In the present study, EC and TDS quality parameters of Karun River were modeled using data-mining algorithms including LSSVM, ANFIS, and ANN, at Mollasani, Ahvaz and Farsiat hydrometric stations. Material and Methods: Eight different inputs including the combination of Cl-1, Ca+2, Na+1, Mg+2, K+1, CO32-, HCO3, and SO42- with discharge flow (Q) were selected as non-ran...
متن کاملSpatial prediction of soil electrical conductivity using soil axillary data, soft data derived from general linear model and error measurement
Indirect measurement of soil electrical conductivity (EC) has become a major data source in spatial/temporal monitoring of soil salinity. However, in many cases, the weak correlation between direct and indirect measurement of EC has reduced the accuracy and performance of the predicted maps. The objective of this research was to estimate soil EC based on a general linear model via using se...
متن کاملA TDR-Based Soil Moisture Monitoring System with Simultaneous Measurement of Soil Temperature and Electrical Conductivity
Elements of design and a field application of a TDR-based soil moisture and electrical conductivity monitoring system are described with detailed presentation of the time delay units with a resolution of 10 ps. Other issues discussed include the temperature correction of the applied time delay units, battery supply characteristics and the measurement results from one of the installed ground mea...
متن کاملApparent soil electrical conductivity measurements in agriculture
The field-scale application of apparent soil electrical conductivity (ECa) to agriculture has its origin in the measurement of soil salinity, which is an arid-zone problem associated with irrigated agricultural land and with areas having shallow water tables. Apparent soil electrical conductivity is influenced by a combination of physico-chemical properties including soluble salts, clay content...
