The underlying processes of evaporative changes: within the transition period in the Miombo Woodlands, Mpika, Zambia in 2018

The Miombo woodlands are characterized by a transition period which is defined as the dry period in which grasses wither, trees shed and flush their leaves a few weeks before the rainy season. It is difficult to measure evaporation, due to the influence of the plant water storage on the water availability during the dry season. The seasonal...

Injectivity reduction in geothermal wells: Investigating the causes

This study investigated the three possible main causes of injectivity reduction in geothermal wells (suspended solids, scaling, biological activity). That has been done by obtaining water samples at three operating geothermal doublet locations in the Netherlands. This paper contains new geothermal data and the interpretation of them. At the...

Measuring and modelling to optimise a salinity monitoring network for use in the optimal control of flushing: Case study: Lissertocht catchment

In deep polders in the Netherlands the dominant mechanism of salinization is via intense seepage through boils. These are local connections between the surface water and a deep saline aquifer. The study area of this research is the Lissertocht. This catchment, which is located inside the Haarlemmermeerpolder, contains a lot of boils that can...

Engineering a horizontal layer of reduced permeability using Al-DOM precipitation

Leakage of contaminants to the subsurface is a potential threat to groundwater and is a major problem with storage tanks. When the contaminant reaches the groundwater, it can be subjected to subsurface flow due to which a contaminant plume may form and the contaminant can spread. In this research, it was investigated if a horizontal layer of...
