Redifining infiltration drywell design: A study on design and functioning in theory as in practice

This research is aimed at creating a generic design method for infiltration drywells on sandy soils by acquiring knowledge on the functioning of these wells. Infiltration drywells are vertical infiltration pipes that are installed above the groundwater table and through which stormwater is drained to the subsurface. Infiltration drywells can...

Mixed in place permeability reductive layer through Al and OM precipitation

The control of infiltration and seepage of water is one ofthe most challenging tasks in water management and civil­-engineering and, inan attempt to control this, methods for forming a water­impermeable layer inthe soil have been widely practised in soil engineering (Laumann et al., 2018;Proto et al., 2016). The use of...

An Evaluation of the In-Situ Hydraulic Conductivity of Cement-Bentonite Walls

Cement-Bentonite (CB) walls are low permeability vertical cut-off barriers that are mainly used to prevent groundwater flow and isolate contaminated areas. The hydraulic performance of the CB walls depends on the flow rate (discharge) through the wall. Therefore, the walls must achieve very low hydraulic conductivity. Poor...

Aqua-purifier phyto-façade system: ‘Exploring the contribution of an active green façade in the purifying of MarineTerrein water’

‘Phytoremediation is the use of plants and their associated microbes for environmental clean-up’(Pilon-Smits, 2005). It is a natural, passive and efficient way of cleaning contaminated soil, water, and air. Every year, there are reports of contamination of swimmers due to the contaminated canal water round the Marineterrein in Amsterdam. The...
