This wiki is under development, there might be omissions and errors. The data in many of the tables is only for demonstration purposes, not based on reality (yet).

Developing new and existing solutions, methods, tools and devices (SMTDs) to improve the environmental performance of hydropower is central in FIThydro, and they are frequently applied on formal documents from the project. FIThydro's understanding of these terms is:

Solutions – these are the overall concept for how to solve or mitigate a problem

Methods – these are typically descriptions in how to do something

Tools - these are methods embedded in for instance a computer program / a model

Devices – these are typically physical instruments or similar used to measure/control, something


The project stages of a mitigation project

The first step before implementing a mitigation measure, is to investigate whether there is a reduction or impact on the fish population. If so, what is the pressure and problem that cause harm to the fish population. Further, suitable mitigation measures must be selected, planned, implemented and maintained. Methods, tools and devices (MTD) for each mitigation measure (solution) are described for three stages:

  1. Planning the measure
  2. Implementing the measure
  3. Maintaining and monitoring the measure

The roles of the MTDs might be different in the three stages of a mitigation project, but sometimes they are also similar. Some MTDs are used for several mitigation measures. Figure 1-1 shows different phases of a hydropower project.

Figure 1 1. The main stages of a hydropower project. The first stage (early project planning) relates to the phase when different sites and designs are investigated. The first stage (early project phase) is a screening phase of various technologies and sites and reduction of impacts and SMDTs deemed irrelevant for the purpose of this report.
