HYDROGEOLOGY

با سلام. خیلی از دانشجویان از مراحل یادگیری مدل سازی آب زیرزمینی سوال کرده بودند. برای شروع مدل سازی ابتدا باید اطلاعاتی در مورد کد مادفلو داشته باشید. یکی از منابع فارسی موجود، کتاب "مدل‌سازی کاربردی جریان و انتقال آلاینده در آبخوان" و دیگری کتاب نون کرسیک است. همچنین می توانید از فصل نهم کتاب Todd استفاده کنید.

در مرحله بعدی باید کار کردن با نرم افزار GMS یاد بگیرید که بهترین روش استفاده از راهنمای خود نرم افزار است که بعد از نصب در این آدرس یافت می شود:

MyDocuments\GMS 7.1\Tutorials\

سپس راهنماها را به دقت و با ترتیب زیر مطالعه کنید:

ابتدا پوشه های Intro - GIS- Geostatistics.

بعد از آن از پوشه MODFLOW فایل های زیر را مطالعه کنید:

MODFLOW-GridApproach
MODFLOW-ConceptualModelApproach
MODFLOW-ModelCalibration
MODFLOW-AutomatedParameterEstimation
MODFLOW-ManagingTransientData

لازم به ذکر است در اینجا حداقل اطلاعات لازم برای مطالعه ذکر شده است و برای مدل سازی پیشرفه نیاز به اطلاعات خیلی بیشتری می باشد.

قیام مجدد اساتید دانشگاه‌های کشور علیه تقلب

وبلاگ «اساتید علیه تقلب» پس از ایجاد برخی تغییرات، با آدرسی جدید فعالیت خود را از سر گرفت.

«اساتید علیه تقلب» نام وبلاگی است که توسط جمعی از اساتید برجسته دانشگاه های کشور اداره می شود. این وبلاگ که قبلا از سرویس بلاگر گوگل استفاده می کرد، از این پس در آدرس pap.blog.ir قابل دسترس کاربران خواهد بود.

در بخش معرفی این وبلاگ می خوانیم: "هدف ما مبارزه با تخلف و تقلب علمی در دانشگاه‌ها چه از سوی دانش‌جویان و چه از سوی اعضای هیات علمی است. متاسفانه ما شاهد گسترش حرکت‌های غیر اخلاقی در فضای علمی کشور هستیم که با انگیزه‌هایی چون اخذ مدرک، پذیرش یا ارتقای مرتبه‌ی دانشگاهی صورت می‌گیرد. ما با هرگونه تقلب مخالفیم و سکوت در برابر آن‌را هم جایز نمی‌دانیم. در این بلاگ قصد داریم برخی موارد و روش‌های تقلب‌ را بیان و ضمن آموزش به دانش‌جویان و تلاش برای اشاعه‌ی اخلاق و آداب حرفه‌ای در جمع خودمان‌، مسولان را وادار کنیم تا به مشکل تقلب و ریشه‌های آن واکنش جدی نشان دهند."

مقاله مدل سازی آب زیرزمینی دشت فیض آباد توسط نرم افزار GMS

برنامه ریزی منابع آب زیرزمینی در شرایط groundwater mining

مطالعه موردی: دشت فیض آباد

عطاءاله جودوی¹- محمد زارع²

¹دانشجوی دکتری آبشناسی، بخش علوم زمین، دانشگاه شیراز

²دانشیار گروه آبشناسی، بخش علوم زمین، دانشگاه شیراز

چکیده

توسعه بدون برنامه کشاورزی و برداشت بیش از حد از منابع آب زیرزمینی دشت فیض آباد (واقع در شمال شرق ایران) باعث بوجود آمدن شرایط groundwater mining و پیامدهای این موضوع مانند افزایش شوری آب زیرزمینی شده است. به علت اقلیم خشک این منطقه، بیشتر آب مصرفی در بخش کشاورزی از منابع آب زیرزمینی تامین می شود. به منظور برنامه ریزی منابع آب زیرزمینی، مدل جریان آب زیرزمینی دشت فیض آباد بوسیله MODFLOW تهیه شد. واسنجی مدل بواسطه انطباق بین سطح آب محاسباتی و مشاهده ای انجام شد و نتایج قابل قبولی بدست آمد. برای ارزیابی تأثیر برنامه فعلی بهره برداری و پیشنهاد کردن راه حل مناسب، چهار سناریوی مدیریتی تنظیم گردید و سناریوها بوسیله مدل مورد آزمایش واقع شدند. بر پایه نتایج مدل، بیلان شبیه سازی شده نشان داد برای متوقف کردن افت سطح آب زیرزمینی لازم است میزان برداشت ماهانه 40% کاهش یابد و در فصل زمستان بهره برداری از آب زیرزمینی صورت نگیرد. آآ

Steady State vs. Transient Modeling

Steady State vs. Transient Modeling

Groundwater flow models describe their capabilities as either steady state and/or transient. It is important when deciding upon groundwater modeling software to know which options are necessary for your needs. This month's newsletter will describe the key differences between steady state and transient modeling.

Steady state flow occurs when the magnitude and direction of flow is constant with time throughout the entire domain. Conversely, transient flow occurs when the magnitude and direction of the flow changes with time. In other words, the hydraulic head doesn't change with time in a steady state flow system, but does change during transient flow. This does not mean that in a steady state system there is no movement of groundwater, it simply means that the amount of water within the domain remains the same, and that the amount of water that flows into the system, is the same amount as flows out.

The steady state flow conditions simplify the groundwater flow equation significantly. When steady state flow occurs, time is no longer an independent variable and thus the storage term in the groundwater flow equation disappears; since there is no change in the amount of water within the domain (no change in hydraulic head) there is obviously no change in the amount of water stored in the domain.

MODFLOW

MODFLOW is the U.S. Geological Survey modular finite-difference flow model, which is a computer code that solves the groundwater flow equation. The program is used by hydrogeologists to simulate the flow of groundwater through aquifers. The code is free software, written primarily in Fortran, and can compile and run on DOS, Windows or Unix-like operating systems.

3-dimensional grid

Since its original development in the early 1980s,the USGS have released four major releases, and is now considered to be the de facto standard code for aquifer simulation. Currently, there are at least five actively developed commercial and non-commercial graphical user interfaces for MODFLOW.

Groundwater flow equation

The governing partial differential equation used in MODFLOW is:

$\frac{\partial}{\partial x} \left[ K_{xx} \frac{\partial h}{\partial x} \right] + \frac{\partial}{\partial y} \left[ K_{yy} \frac{\partial h}{\partial y} \right] + \frac{\partial}{\partial z} \left[ K_{zz} \frac{\partial h}{\partial z} \right] + W = S_{S} \frac{\partial h}{\partial t}$

where

$K x x$ , $K y y$ and $K z z$ are the values of hydraulic conductivity along the x, y, and z coordinate axes (L/T)
$h$ is the potentiometric head (L)
$W$ is a volumetric flux per unit volume representing sources and/or sinks of water, where negative values are extractions, and positive values are injections (T⁻¹)
$S S$ is the specific storage of the porous material (L⁻¹); and
$t\,$ is time (T)

Finite difference

The finite difference form of the partial differential in a discretized aquifer domain (represented using rows, columns and layers) is:

$\begin{align} & CR_{i,j-\tfrac{1}{2},k}\left(h^m_{i,j-1,k}-h^m_{i,j,k}\right) + CR_{i,j+\tfrac{1}{2},k}\left(h^m_{i,j+1,k}-h^m_{i,j,k}\right) + \\ & CC_{i-\tfrac{1}{2},j,k}\left(h^m_{i-1,j,k}-h^m_{i,j,k}\right) + CC_{i+\tfrac{1}{2},j,k}\left(h^m_{i+1,j,k}-h^m_{i,j,k}\right) + \\ & CV_{i,j,k-\tfrac{1}{2}}\left(h^m_{i,j,k-1}-h^m_{i,j,k}\right) + CV_{i,j,k+\tfrac{1}{2}}\left(h^m_{i,j,k+1}-h^m_{i,j,k}\right) + \\ & P_{i,j,k}\,h^m_{i,j,k} + Q_{i,j,k} = SS_{i,j,k}\left(DELR_j \cdot DELC_i \cdot THICK_{i,j,k}\right) \frac{h^m_{i,j,k}-h^{m-1}_{i,j,k}}{t^m-t^{m-1}} \end{align}$

where

$h^m_{i,j,k}\,$ is the hydraulic head at cell i,j,k at time step m
CV, CR and CC are the hydraulic conductances, or branch conductances between node i,j,k and a neighboring node
$P_{i,j,k}\,$ is the sum of coefficients of head from source and sink terms
$Q_{i,j,k}\,$ is the sum of constants from source and sink terms, where $Q_{i,j,k}<0.0\,$ is flow out of the groundwater system (such as pumping) and $Q_{i,j,k}>0.0\,$ is flow in (such as injection)
$SS_{i,j,k}\,$ is the specific storage
$DELR_j\,$ , $DELC_i\,$ and $THICK_{i,j,k}\,$ are the dimensions of cell i,j,k, which, when multiplied, represent the volume of the cell
$t^m\,$ is the time at time step m

Limitations

The water must have a constant density, dynamic viscosity (and consequently temperature) throughout the modelling domain (SEAWAT is a modified version of MODFLOW which is designed for density-dependent groundwater flow and transport)

$\mathbf{K} = \begin{bmatrix} K_{xx} & 0 & 0 \\ 0 & K_{yy} & 0 \\ 0 & 0 & K_{zz}\end{bmatrix} \$

The principle components of anisotropy of the hydraulic conductivity used in MODFLOW is displayed on the right. This tensor does not allow non-orthogonal anisotropies, as could be expected from flow in fractures. Horizontal anisotropy for an entire layer can be represented by the coefficient "TRPY" (Data Item 3 Page 153 ^[2].
