[ 1 ] - A New GIS based Application of Sequential Technique to Prospect Karstic Groundwater using Remotely Sensed and Geoelectrical Methods in Karstified Tepal Area, Shahrood, Iran
In this research, recognition of karstic water-bearing zones using the management of exploration data in Kal-Qorno valley, situated in the Tepal area of Shahrood, has been considered. For this purpose, the sequential exploration method was conducted using geological evidences and applying remote sensing and geoelectrical resistivity methods in two major phases including the regional and local s...
[ 2 ] - Karstic water exploration using the Schlumberger VES and dipole–dipole resistivity profiling surveys in the Tepal area, west of Shahrood, Iran
The need for clean groundwater resources to have sustainable development in a country is undoubted. Due to the importance and high quality of karstic waters in supplying water in Iran especially in Shahrood city, it is attempted in this research work to recognize and explore karstic waters in southwest of Tepal area, Shahrood. For this purpose, integration of the results obtained from the metho...
[ 3 ] - شبیه سازی عددی داده های رادار نفوذی به زمین (GPR) برای آشکارسازی مین های فلزی
پاک‌سازی میادین مین و مناطق آلوده به مواد منفجره عملنکرده یکی از مسائلی است که در کشورهای جنگزده و از جمله کشور ما، با وجود گذشت دهها سال از زمان جنگ، نیازمند توجه جدی است. روشهای مختلف ژئوفیزیکی از جمله روش GPR نقش بسیار مهمی در آشکارسازی محل این آثار مخرب باقیمانده از جنگ دارند. روش GPR هوابرد به دلیل قابلیتها و برتریهای خاصی که نسبت به روش برداشت زمینی دارد، توجه ویژه متخصصان امر را به...
[ 4 ] - One-Dimensional Modeling of Helicopter-Borne Electromagnetic Data Using Marquardt-Levenberg Including Backtracking-Armijo Line Search Strategy
In the last decades, helicopter-borne electromagnetic (HEM) method became a focus of interest in the fields of mineral exploration, geological mapping, groundwater resource investigation and environmental monitoring. As a standard approach, researchers use 1-D inversion of the acquired HEM data to recover the conductivity/resistivity-depth models. Since the relation between HEM data and model ...
[ 5 ] - Using a combination of genetic algorithm and particle swarm optimization algorithm for GEMTIP modeling of spectral-induced polarization data
The generalized effective-medium theory of induced polarization (GEMTIP) is a newly developed relaxation model that incorporates the petro-physical and structural characteristics of polarizable rocks in the grain/porous scale to model their complex resistivity/conductivity spectra. The inversion of the GEMTIP relaxation model parameter from spectral-induced polarization data is a challenging is...
