= Data required =

== Biological data ==
 - Density and null density
 - Date of the sampling, method used
 - Characteristic of the station : width of the river

 - Size of eel
 - Coordinate system for each station

== Dams data ==
 - Coordinates of each dams
 - Height, rugosity, passability of the dam, type of materials  see in ["Obstacles Score Spain"]

== To calculate Bcurrent, Bbest, Bpristine ==
 - Wglass, Wyellow, Wsilver : mean weigth of glass eel, yellow eel and silver eel
 - τ : lifespan of eel
 - λyellow : mean age of yellow eel
 - Yglass, Yyellow, Ysilver : anthropogenic impact of glass eel, yellow eel and silver eel

== Other data ==
 - River flow
 - Geology
 - Turbines (Hydroelectric dams) with diameter, speed...

== River network in Spain ==
 - topology of the river network : relationship between mainstream and tributaries, headwaters, drainage system and outlet. 
 - strahler order or shreve order
 - length of the river
 - river width
 - local hydrographic basin (catchment)
 

= Steps to apply EDA to the whole of Spain =
 == Integrating electrofishing data into the dbeel ==
   ["Spain electrofishing data"]

 == Dams ==
   - Import dam data into postgres
   - Build the table joining dam data
   - Run R program to calculate the cumulated number of dams from the sea. 
   - Run R program to calculate the cumulated score [[BR]]
   ["Spain dams"]

 == CLC Corine Land Cover ==
   - Run the program to calculate the clc numbers
   - Run sql script
   - Run R program  [[BR]]
   ["Spain clc"]

 == Caracteristics of river network ==
   - Run the program to calculate the distance to the source, distance to the sea, upstream catchment  [[BR]]
   ["Spain river network caracteristics"]
