DC-Dewatering

The DC-Dewatering program calculates groundwater lowering with multi-well installations. The calculation can be performed for the lowering of groundwater in several adjacent excavation pits of different depths with any number of wells and in a staggered arrangement.

• Any number of excavation pits can be defined with different shapes and depths
• Optional waterproof enclosure and waterproof invert
• Selection of various well systems: vertical or horizontal wells, vacuum or gravity wells, open dewatering
• Any number of wells with different diameters, depths and lowering aims
• A staggered arrangement of the wells is possible
• Optional automatic arrangement of wells with predefined diameters, depths and distances from the edge of the excavation pit (optimisation of the well location and depth)
• Horizontal soil stratification with different permeabilities
• Free, semi-confined or confined groundwater, optionally with a fixed water level from a nearby water body
• Lowering depth either predefined or adapted to the excavation depth
• Calculation and indication of the required pump water quantity, capacity, lowering and wetted filter height per well
• Calculation of the decisive point for the lowering
• Calculation of the required number of wells
• Calculation of the extent according to Sichardt, according to Weyrauch, according to Weber or time-dependent
• Consideration of the influence of the wells on each other depending on their spacing
• Calculation of the residual flows from the wall and the invert as well as the inflows from precipitation for the trough construction
• Representation of the lowering via contour lines or coloured areas
• Representation of the water level along any section line
• The lowering can be displayed at any point in the user interface
• For the accurate internal modelling of the excavation pit dimensions, it is possible to import DXF graphics as a background.
• Output options: printer, PDF
• Interfaces: RTF export to MS Word, graphic export in JPG format, DXF export
