CHANNEL GRADIENT: Calculation process using GIS

This technical note on river restoration adresses the calculation of river channel gradients using Geographic Information Systems (GIS). The channel gradient is a fundamental parameter in the geomorphologic characterisation of river systems; it is a reflection of the changes in the longitudinal sequence of a river through the presence of waterfalls, step pools (fasts and pools), riffle pools (rapids and pools), etc., which makes it a discriminating factor of environmental dynamics of differentiated processes.

RIVER SINUOSITY INDEX: Geomorphological characterisation

This technoical notes on river restoration explores the concept of sinuosity. Sinuosity is used to define the degree of meandering of a riverbed, which is then used to establish geomorphological river types.

FLUVIAL TERRITORY: Restoration space

This technical note on river restoration explores the concept of Fluvial Territory as a space of sufficient width and continuity to retain or regain the hydro-­‐geomorphologic dynamic, obtain a continuous riverside passageway that would ensure ecological diversity (Habitats Directive 1992/43/CE) and the bioclimatic function of the river system, comply with a good ecological state (Water Directive 2000/60/CE), laminate the avenues naturally (Flood Directive 2007/60/CE), solve management problems of floodable areas, as well as improving and consolidating the landscape around the river.

Managing Mali’s Wetland Wealth for People and Nature

Wetlands International has been in Mali since 1998. As we near the end of a second decade in the country, we want to highlight and celebrate what’s been achieved and learnt within our growing network of partners. This document reflects on projects past while also looking to the future. More important still, it is a call for partners, old and new, to join us in writing the next chapters of the story – partners with the necessary funds, creativity, vision, ambition and energy to carry this exciting work forward.

Poster : Canal Blocking

Canal Blocking has many benefits :

  • Restoration of 'wet' peat characteristics and reduction of fire
  • Return of the carbon sequestering capacity of peatland
  • Re-establishment of the water buffer fucntion and a reduction of floads
  • Opportunity to plant economically viable species like Jelutung for rubber and Tengkawang (illevenut) for edible oil production; it opens also possibilities for different forms of aquaqulture
  • return of original biodiversity that is opten unique to peat swamp forest

Wetland management planning – a methodology manual for managers

The wetland management planning manual provides a stepwise approach to formulate an integrated management plan. Compiled based on existing guidelines and best practices, this manual caters to the need of Indian wetland managers. This document is essentially a work in progress, and will be updated with more information soon.   more..

A sustainable solution for massive coastal erosion in Central Java

We developed a new approach called ‘Hybrid Engineering’, which addresses delta and coastal vulnerability in an integrated manner. This approach accommodates economic and livelihood development needs, and combines technical and ecosystem-based solutions. The Hybrid Engineeringapproach is aimed to work with nature rather than against it.

Wetlands International Annual Report 2013

The “red thread” for our work in 2013 was our increasing connection, dialogue and influence with other civil society organisations, business and industry. As you glance through the Achievements section in the report, you will see many concrete examples of this, with on-ground and policy results evident from the local to global scale. Through our major programmes we have demonstrated how wetlands play a vital role in securing biodiversity, strengthening livelihoods, increasing community resilience natural hazards like floods and droughts and reducing greenhouse gas emissions.
