Drainage of deposits and excavations 1300-OOZWBCW

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.

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).
