Summary
Subject Geohydrodynamics gives a basic overview of patterns of groundwater flow in the rock environment in both saturated and unsaturated zones. In addition to the problems of porous media flow, attention is paid to hard rock – fracture flow (Cubic Law). Students are acquainted with the hydraulic parameters of aquifer and the methods of their determination in the laboratory and with hydrodynamic field tests. Students are encouraged to practice using analytical calculation equations - calculation of fluxes through the dam, hydraulic systems for dewatering construction pits, etc.
Learning Outcomes of the Course Unit
The aim is to cover a wide range of topics (see annotation) so we approached the students with basic terminology, principles and methods in the given subject and their practical application.
Course Contents
Lectures:
1. Physical properties of fluids (density, specific gravity, compressibility, thermal expansion, viscosity, surface and contact tension, gas solubility - basic relationships and units).
2. Physical properties of aquifer (permeability, transmisivity, porosity, volumetric elasticity of aquifer, storativity, hydraulic conductivity - basic relations and units).
3. Systematics of the types of filtration fluxes - basic characteristics and overview of basic flow equations.
4. Law of continuity of flow - general continuity equation (steady and transient filtration of compressible and incompressible fluids).
5. Darcy's Linear Law (Problems of filtration rates, tortuosity). Nonlinear laws of filtration. Turbulent flow.
6. Basic equations of gravitational fluxes of incompressible fluids (Boussinesq equation) – unconfined conditions.
7. Basic equations of fluid filtration under confined conditions (incompressible, compressible under low and high-pressure).
8. Basic analytical equations for flows under steady flow conditions in confined and unconfined systems (Dupuit equations).
9. Depression cone (shape and characteristics). Basic computational relationships. Transient behavior of groundwater drawdown. Interference of wells (depression cones).
10. Basic analytical equations for flows under transient flow conditions in confined and unconfined systems (Theiss equations).
11. Methods of hydrodynamic testing – pumping tests, recovery tests, slug tests.
12. Hydrodynamic testing under steady state flow conditions (confined and unconfined aquifer). Dupuit method.
13. Hydrodynamic testing under transient flow conditions (confined and unconfined aquifer). Theiss type type curves, Jacob's method.
14. Hydraulic boundary conditions, their significance and manifestations in hydrodynamic tests.
