Using the devalpomi report (Loire - Bretagne) adapt scripts to integrate the size structured version of the EDA model. Adapt and check Mortalite_turbines.Rmd test report. Check that results are consistent with those found in the Adour by Antoine Martelet The current version of devalpomi uses distance to the sea to propose a size structure for downstream migrating silver eels, now this feature is available within devalpomi. We had best use it. This is also ticket#102 This is also ticket #106

DEPENDING ON THIS ticket #147 (Adapt parcours method to calculate mortality for only one class of dams or several) depending on the status dubious (ROE) or not (ICE) of the dam information. ticket #148 (Adapt plot method) ticket #149 (summary tables per dam)

Checks still to be done

source C:/workspace/p/devalpomi/R/tableau_mortalite.R

The current caculation is based on a average size structure per distance to the sea Mortality is calculated for class 100 to 900 and size structure in percentage is provided. This should be replaced by the calculation at the average size of each size class. A vector of results per size should be stored in the output table tableau_mortalite

There is a taux_min taux_max, what use ? Remove ? Document the scripts

Loire & brittany

Use data from the Vilaine, Oir, Loire, Sèvre Niortaise. Compile downstream migration and flow data. Relate to classified flows (cut according to flow quantiles) Percentage of annual migration ~ classified flows Calcul des moyennes par bootstrap

either a vgam either a bayesian model with proportions With pc proportion per flow catch pc<-cut (flow, percentiles station hydro)

data | perc migration | flow class 01/01 | 2% | pc1 02/01 | 1% | pc2

=> sum (perc migration) ~flow class

per year we get percentage migration on flow class

pc1 20% pc2 25% pc3 15%

Migration flow are curently a repartition 20 % between Q50 Q90 Q95 Q97 Q99 Add a coefficient for each flow, perhaps modidify the flow regime to allow more little flow.
