ASSESSMENT OF SMALL-SCALE HYDROPOWER RESOURCES - HydrA
1. Purpose and objectives
To enable rapid assessment of run-of-river hydropower generation
HydrA is software for PCs that facilitates systematic estimation of
small-scale hydropower potential at any site in specified regions, i.e. at
gauged or ungauged sites in regions where preparatory regionalisation
analysis using catchment characteristics and available hydrometric data has
been undertaken previously. The site is defined by a catchment boundary,
the co-ordinates of which are input to HydrA by the operator. The flow
regime at the point in question, expressed as a flow duration curve, is a
key step. At gauged sites with sufficiently long flow records the flow
duration curve can be specified and input to HydrA by the user. For
ungauged sites, HydrA prepares a synthetic flow duration curve on the basis
of a regional normalised flow duration curve and an overlay of gridded
runoff onto the specified catchment area. To be operational for a given
region, HydrA must already contain (hard-coded) regional, normalised, flow
duration curves and gridded runoff data for the region of application,
Versions of the HydrA software are available for the United Kingdom and Spain (HydrA), Nepal (HydrA-Nepal) and Himachal Pradesh, India (HydrA- HP). A version of HydrA covering Italy, Belgium, Ireland and Portugal has also been prepared. A comprehensive User Guide is available for each version of HydrA.
A demonstration version of HydrA (restricted to an example catchment)
is available free of charge on request.
