Identifying crop vulnerability to groundwater abstraction: Modelling and expert knowledge in a GIS

Identifying crop vulnerability to groundwater abstraction: modelling and expert knowledge in a GIS.

Water use is expected to increase and climate change scenarios indicate the need for more frequent water abstraction. Abstracting groundwater may have a detrimental effect on soil moisture availability for crop growth and yields. This work presents an elegant and robust method for identifying zones of crop vulnerability to abstraction. Archive groundwater level datasets were used to generate a ...

GIS and Statistical Groundwater Vulnerability Modeling

ArcGIS Desktop* and ArcGIS Workstation* were used to extract statistically significant information from various geospatial data sets for input into a statistical model of groundwater vulnerability. The product of this effort was a probability map that identified areas of vulnerability to groundwater-quality degradation. This information is of interest to a variety of water professionals because...

Groundwater vulnerability to pollution mapping of Ranchi district using GIS

Groundwater pollution due to anthropogenic activities is one of the major environmental problems in urban and industrial areas. The present study demonstrates the integrated approach with GIS and DRASTIC model to derive a groundwater vulnerability to pollution map. The model considers the seven hydrogeological factors [Depth to water table (D), net recharge (R), aquifer media (A), soil media (S...

GIS-based DRASTIC method for groundwater vulnerability assessment: a review

identifying the strategies persian efl learners use in reading an expository text in english and examining its relation to reading-proficiency and motivation: a think-aloud study

هدف اصلی از این مطالعه بررسی نوع و میزان استراتژی هایی بود که دانشجویان فارسی زبان رشته ی زبان انگلیسی در حین خواندن یک متن انگلیسی به کار گرفتند. این مطالعه همچنین به بررسی تفاوت های استراتژی های مورد استفاده بین دارندگان سطح بالا و پایین درک مطلب پرداخت. نوع همبستگی بین استراتژی به کار گرفته و درک مطلب از یک سو و استراتژی به کار گرفته و انگیزه از سوی دیگر نیز در این تحقیق مورد آزمایش قرار گرف...
