21. Urban Snowmelt Processes: Modelling and Observation
Sammanfattning : In northern Scandinavia and other cold regions, urban drainage systems are often unable to cope with the high volumes of melt water which can be sustained for several weeks. High waste water treatment plant inflows, combined system overflows and low water quality are a few problems associated with snowmelt. LÄS MER
22. Resistivity investigation and monitoring for detection of internal erosion and anomalous seepage in embankment dams
Sammanfattning : Methods for monitoring seepage and detecting internal erosion are essential for the safety evaluation of embankment dams. Internal erosion is one of the major reasons for embankment dam failures, and there are several tenths of thousands of large embankment dams in the world. LÄS MER
23. The Integrated Distributed Hydrological Model, ECOFLOW- a Tool for Catchment Management
Sammanfattning : In order to find effective measures that meet the requirements for proper groundwater quality and quantity management, there is a need to develop a Decision Support System (DSS) and a suitable modelling tool. Central components of a DSS for groundwater management are thought to be models for surface- and groundwater flow and solute transport. LÄS MER
24. Properties of heavy rainfall in an East Asian monsoon catchment - Analysis of daily rain gauge data
Sammanfattning : The East Asian monsoon has a strong seasonal effect on the rainfall regime of Eastern China. In order to mitigate floods and conserve the water for use throughout the year, dams and other hydro-structures are built. The design of the structures requires knowledge of the rainfall characteristics that influence the inflow to them. LÄS MER
25. Application of the SASW-technique in geotechnical in-situ testing
Sammanfattning : With the main aim to test the applicability of the surface wave seismic technique Spectral Analysis of Surface Waves (SASW), used for determination of the shear stiffness (shear modulus - Gmax), four areas of applications have been studied. The four areas have been sites with natural geological conditions, sites where non destructive testing is necessary, pavement testing and multichannel testing. LÄS MER
