Most cities in Denmark are situated on low permeable clay rich deposits. These sediments are of glacial origin and range among the most heterogeneous, with hydraulic conductivities spanning several orders of magnitude. This heterogeneity has obvious consequences for the sizing of sustainable urban drainage systems (SuDS). We have tested methods to reveal geological heterogeneity at field scale ...

GD-20 is a brand new multichannel geo-electrical system, designed with 5 or 12 channels and up to maximum 10 survey points can be measured concurrently for ERT survey, highly enhancing field survey efficiency. GD-20 can be used in SP, ERT and IP surveys. Comparing to single channel instruments, GD-20 boosts ERT survey efficiency up to 2-3 times in average and lowering working duration of field ...
