6. Soil compaction: effects on soil hydraulic properties and preferential water flow
Sammanfattning : Soil compaction caused by passage of agricultural machinery over the surface is an issue in many agricultural soils with a high clay content. Compaction is known to modify soil pore structure and soil hydraulic properties, but can also affect the occurrence of preferential flow. LÄS MER
7. Conceptualization of solute transport using time domain reflectometry. A combined laboratory and field study
Sammanfattning : Solute transport in the unsaturated zone is a complex process. The first of the two objectives for this study was to examine how it could be conceptualized under different flow conditions. LÄS MER
8. The Lagrangian Stochastic Advective-Reactive Approach to Modeling Solute Transport in Hydrological Systems
Sammanfattning : The Lagrangian stochastic advective-reactive modelingapproach has been used for analyzing transport of bothnonreactive and reactive solutes in different hydrologicalsystems (structured soil, groundwater, mining waste rockdeposits and surface waters including single stream and networkof streams) and at different spatio-temporal scales (rangingfrom laboratory column-scale to catchment-scale). Further, afirst step has been taken to extending the Lagrangianstochastic advective-reactive modeling methodology to integratethe soil-groundwater-stream transport through a catchment. LÄS MER
9. Water and Heat Balances for Urban Surfaces
Sammanfattning : Water and heat flows for three different types of surfacefound within Stockholm, Sweden, were simulated with asoil-vegetation-atmosphere transfer (SVAT) model. Theinfiltration process of a till soil was investigated toestimate the importance of preferential water flow. LÄS MER
10. The importance of tree cover for water resources in semiarid West Africa
Sammanfattning : The current paradigm in forest hydrology implies that an increase in tree cover always leads to reduced water yields as a result of increased interception and transpiration (ET) losses. This trade-off theory, in which more trees mean less water, has led to concerns that the establishment of trees in drylands may jeopardize scarce water resources. LÄS MER
