Lancashire lad working on Yorkshire’s rivers || Geomorphology || Using natural processes to reduce flooding and benefit wildlife

[Jonathan Grey @ProfJGrey]

This reach of Flasby Beck was straightened & dredged this century! @_Chris_Nash_ & I dreamt up a scheme. @wildlifetoursuk intro'd the landowner. Today, @WildTroutTrust for #UpperAireProject broke ground, lowering banks & raising bed + reconnecting paleochannels

@ProfJGrey @RichardTong3 @YorksWildlife @WildTroutTrust @Theo_Pike @PaulNGaskell @PeteTurnerEA @aireriverstrust @AireCatchment @SandTCUKYorks @fishmigration @OpenRiversProg @leedscitycounc1 Worth a peek when you’re next around.

Agree re. fines. Though hopefully the floodplain connectivity & roughness here is promoting out of bank deposition / acting as a sediment store.

Last one, I promise.

@RichardTong3 @ProfJGrey @YorksWildlife @WildTroutTrust @Theo_Pike @PaulNGaskell @PeteTurnerEA @aireriverstrust @AireCatchment @SandTCUKYorks @fishmigration @OpenRiversProg @leedscitycounc1 Yep, despite the historic modification (associated with the former Scotland Mill) the reach immediately upstream of the ring road is relatively nice 👍

[Chris Nash @_Chris_Nash_]

Thoughts from yesterday's lunchtime walk up #MeanwoodBeck: Plenty of new, naturally recruited, in-channel wood (thanks #StormArwen). Wood plays an important role in our rivers – increasing aquatic habitat availability & diversity, whilst also slowing flows & providing #NFM

[Chris Nash @_Chris_Nash_]

@ProfJGrey @YorksWildlife @WildTroutTrust @Theo_Pike @PaulNGaskell @PeteTurnerEA @aireriverstrust @AireCatchment @SandTCUKYorks @fishmigration @OpenRiversProg Look forward to seeing the plans!

Our predecessors have a lot to answer for… then & now images of the straight, re-sectioned & concrete lined section of channel immediately upstream of Grove Lane.

[Jonathan Grey @ProfJGrey]

5y ago, @FreestoneFF told me of #trout by @MeanwoodFarm. Last year @YorksWildlife @_Chris_Nash_ & I walked & talked the beck. Today, #FFS & I were sizing up solutions for #fishpassage @ 15 weirs + habitat potential

@ProfJGrey @fishmigration @WildTroutTrust @Theo_Pike @PaulNGaskell @PeteTurnerEA @SandTCUKYorks @FreestoneFF @StuBamforth @aireriverstrust @YorksWildlife @EAGeomorphology @ProfJGrey Looks like the mighty Meanwood Beck? My local river! Would be to catch up, hear your thoughts and share ideas.

An article on the importance of the hyporheic zone and its vital role in the health of rivers

Every culvert, weir & hard bed protection potentially serves to disrupt/degrade this vital part of the ecosystem

#RiverMonster?
There's been a mill & weir @ Scotton >250y. Redundant, it serves only to fragment & degrade our natural heritage.
@WildTroutTrust funded by @OpenRiversProg will remove it this month, reinstating #fishpassage & #geomorphology

Incredible footage from an helicopter of the mountain rescue of the basal detachment in Marmolada.

Water lubrication at the base (or interstrata) and increased pressure in water-filled crevasses are probably the main causes for this catastrophic event

[Chris Nash @_Chris_Nash_]

@ProfJGrey @BradfordsBecks @WildTroutTrust @aireriverstrust @EAGeomorphology @KirstyBreaks @BradfordNature @ProfJGrey Wow… some sorry sights here. Though, the presence of in-channel woody material and its interaction / impact on morphology in the last two photos is interesting to see!

[Jonathan Grey @ProfJGrey]

The signs were there... Just like downstream

#NFM in action on #MeanwoodBeck during #StormFranklin. In-channel & #riparian woody material creating roughness, promoting #FloodplainConnectivity & slowing flows. Protecting (& restoring) naturally functioning systems like this helps provide resilience to #ClimateChange.

[Chris Nash @_Chris_Nash_]

A couple of snaps of a swollen #MeanwoodBeck this afternoon.

[Chris Nash @_Chris_Nash_]

Unfortunately also plenty of #pollution entering the beck. From surface water runoff laden with fine #sediment to point source pollution - including these repeat offender manhole covers, one of which was spilling #sewage & leaving a trail of wet wipes to prove it 💩🤢
