ECTS credit allocation (and other scores): 4.00 Basic information on ECTS credits allocation principles:
  • the annual hourly workload of the student’s work required to achieve the expected learning outcomes for a given stage is 1500-1800h, corresponding to 60 ECTS;
  • the student’s weekly hourly workload is 45 h;
  • 1 ECTS point corresponds to 25-30 hours of student work needed to achieve the assumed learning outcomes;
  • weekly student workload necessary to achieve the assumed learning outcomes allows to obtain 1.5 ECTS;
  • work required to pass the course, which has been assigned 3 ECTS, constitutes 10% of the semester student load.
Language: Polish
Type of course:

obligatory courses
Prerequisites (description):

Students should have basic knowledge related to:

- methods of hydrological research used in hydrogeology

- elements of hydraulics

- types of water flow and the rules that govern them, flow of water under pressure in pipes

- hydraulic losses, siphon systems and types of pumps

- water outflow from holes and overflows

- basics of the water management in Poland

- systematic of hydrogeology

- chemical composition and physical properties of groundwater and interpretation of hydrogeochemical analyses

- groundwater flow and the rules that govern it

- groundwater resources

- methodology of hydrogeological field research

- methodology of geological drilling

- basics of hydrogeological projections


The knowledge on these subjects a student can earn during the following obligatory subjects conducted at UW:

- "Hydrology and hydraulics" (lecture and exercises of at least one semester),

- Hydrogeology (lecture and exercises of at least two semesters);

- Drilling (lecture and exercises of at least one semester).
Short description:

Hydrogeological and hydrological conditions of events course resulting in changes of water in urban areas. Origin of water, intensity of rainfall, water receivers. Hydrogeological conditions of excavations drainage. Division and extent of surface and underground drainage systems in the built-up areas. Drainage of construction areas. Computational models of drainage and factors determining sizing of dewatering. Differences in the vertical, horizontal and mixed drainage.Methods of direct dewatering of foundation trenches. One and two stage drainage trenches. Application of wellpoints and draining wells. Design and exploitation of wellpoints. Ground filters. Geotextiles and geofabrics. Principles of making filters and arrangement of drainage. Drainage of pathways. Drainage ditches - storm water drainage and its components. Mine drainage systems, water hazards, prognosis of water hazards associated with the liquidations of mines.
Full description:

The lecture is designed to acquaint a student with:

- security capabilities of an excavation by leakproof or fissural walls and assessing volume of percolation on connectors,

- classification and distribution of drainage of construction areas, the need and occurrence of their application

- computational models of drainage and hydrogeological conditions of their use,

- types of groundwater drainage,

- methods of dewatering of foundation trenches

• wellpoints and draining wells

• horizontal drains,

• drainage urfa,

• urfach drainage,

- usage of geotextiles and geofabrics,

- methods of pathways drainage

• wellpoints

• drainage ditches,

• other types of dewaterings

- projection of rainwater drainage

- mine drainage systems,

- prognosis of water hazards associated with liquidations of mines.

The classes are concentrated on:

- assessment of manner of securing an excavation or dewatering, depending on type of an excavation and hydrogeological conditions,

- calculation of volume of percolation on connectors of leakproof or fissural walls

- calculation of volume of surface recharge to an excavation through fissural walls

- calculation of inflow volume into wellpoints and drainage wells system around an excavation of foundation in aquifer of weak parameters of filtration,

- calculation of inflow volume into dewatering wells system around an excavation of foundation in aquifer of good parameters of filtration,

- calculation of inflow volume into segmentation line of an excavation

- calculation of inflow volume into a ditch,

- estimating volume of inflow to mines,

- projection of rainwater drainage.
