 - the water fluxes that leave the soil are (i) the surface runoff, drainage, and bare soil evaporation (evapnu), which are produced over SUM(soiltile(ji,:))=vegtot+totfrac_nobio, (ii) the transpiration and interception loss, which are only produced from the PFT 2 to nvm, corresponding to soiltile(ji,2)+soiltile(ji,3). This sends back to my question regarding enerbil, although I don't imply this is wrongly done in the code.
 
+AD: a point that raises doubt on the use of frac_nobio and vegtot in hydrol is that it is different from its use in hydrolc (Choisnel), in which the "soil" fraction does not include frac_nobio. Despite this difference, the water budget calculations are very similar in hydrol_waterbal and hydrolc_waterbal:
+- hydrolc_waterbal: 
+{{{
+tot_water_end(ji) = (mean_bqsb(ji) + mean_gqsb(ji))*vegtot(ji) + &
+            & watveg(ji) + snow(ji) + sum_snow_nobio(ji)
+tot_flux(ji) =  precip_rain(ji) + precip_snow(ji) + returnflow(ji) + reinfiltration(ji) + irrigation(ji) - &
+             & sum_vevapwet(ji) - sum_transpir(ji) - vevapnu(ji) - vevapsno(ji) - vevapflo(ji) + &
+             & floodout(ji)- run_off_tot(ji) - drainage(ji)
+}}}
 
+- hydrol_waterbal:      
+{{{
+tot_water_end(ji) = humtot(ji)*vegtot(ji) + watveg + &
+            & snow(ji) + SUM(snow_nobio(ji,:))
+tot_flux(ji) =  precip_rain(ji) + precip_snow(ji) + irrigation (ji) - &
+            & SUM(vevapwet(ji,:)) - SUM(transpir(ji,:)) - vevapnu(ji) - vevapsno(ji) - vevapflo(ji) + &
+            & floodout(ji) - runoff(ji) - drainage(ji) + returnflow(ji) + reinfiltration(ji)
+}}}

+- which was the model for the new total water budget residu (twbr) diagnostic:
+{{{
+twbr(ji) = (vegtot(ji)*delsoilmoist(ji) + delintercept(ji) + delswe(ji)) &
+            - ( precip_rain(ji) + precip_snow(ji) + irrigation(ji) + floodout(ji) &
