To assess the environmental factors controlling floods in Tajikistan, comparisons were made between the river flows in each river basin and the climate in different locations. The analysis identified those basins with the highest floods and produced indicative results of the main climatic controls. This enabled a further assessment to be made of the likely [...]
Tajikistan weather observation station Flooding is not a new phenomenon in Tajikistan, there is evidence from a range of sources that major floods have occurred in historical times. Landforms in the mountains and foothills supply ample evidence of extreme paleo-floods. Debris flows have occurred in most of the high mountain catchments with huge fans of [...]
Scotland has a new law on flood management. This replaces the old flooding law from 1961 and brings Scotland right up to date with a modern and sustainable approach to flood management.
Aerial view of typical Callander flooding The Callander NFM project aims to restore natural drainage and wet woodland on an extensive area of floodplain to reduce the downstream flood risk through Callander. This project is proposed in two phases: Detailed design of the restoration work Implement the work and monitor the effectiveness in terms of [...]
Final site tidying up around the upper logjam Here is the first update on the Meander Restoration project outlined in a previous post, including day-by-day diary extracts and linked slideshows showing the August 2009 completion of the groundworks phase of the project.
Landslip in the Langtang Valley – Nepal Sediment loads of Asian rivers are reported to be the highest in the world, delivering an estimated 80% of total sediment input to the oceans. These large sediment loads are due to the exposure of the geologically young rocks forming the Himalayan mountain chain, a range with some [...]
Research carried out by MNV groundwater hydrologist Sally Homoncik through Edinburgh University and the British Geological Survey, compiled a database of the distribution of manganese (Mn), a naturally occurring trace metal, in Scottish groundwater. This is linked to an investigation into the occurrence of the metal in drinking water supplies. Results showed that 28% of Scottish [...]
Normally part of natural flood management, this technique is designed to restore river channel features, to dissipate and absorb the energy of high flood flows. Natural river features include meanders, sediment features, rocks and large woody debris. The meanders are usually best developed from the piedmont zone and further downstream. In this part of a [...]
