• Case study:Belton Floodplain Reconnection and River Restoration  + (When planning a large-scale project of thi … When planning a large-scale project of this nature, the first consideration should be what is the lowest cost and least disruptive way of achieving the objectives. Previous habitat works have focussed on lowering the floodplain to meet the water surface. This is often costly with excess spoil to move and spread and has a high initial impact on site both ecologically and aesthetically. It can also be very effective to work up projects in several phases over several years to allow interventions to be in and establish e.g channel narrowing followed by gravel introduction.narrowing followed by gravel introduction.)
• Case study:Woughton on the Green bank stabilization  + (While the project was successful at stabil … While the project was successful at stabilizing the bank where it was most at risk (i.e. steep and close to public footpath), the bank poaching caused by dogs has just moved to another location. This should be considered in any similar project that seeks to restore bank that is deteriorating as a result of livestock or recreational activity. Consider where dogs or livestock will next enter the river, and consider whether the river at that point will be sensitive to the pressure. Are there any other unstable banks or important habitats such as spawning gravels that may be impacted? Consider whether fencing or formal drinking bathing points may be required.l drinking bathing points may be required.)
• Case study:Slow the Flow, Broadland Rivers, Norfolk  + (With close liaison with permitting and enforcement colleagues it is essential to apply the relevant legislation appropriately. This is used as a pilot scheme for other projects which are linked with WWF/Waterlife/Coca Cola over the next 3 years.)

• Case study:Houghton 'trout stream' enhancements  + (Wood for construction of deflectors was so … Wood for construction of deflectors was sourced locally and work was undertaken by hand. Therefore the size of deflectors were limited to what could be manoeuvred by hand. Despite their size, careful consideration of the prevailing flow and sediment conditions meant they could be placed to achieve optimum benefit.</br></br>In November 2014 some of the wooden posts, used to hold deflectors in place, had to be replaced. The posts were 75 mm diameter and it is thought that the staples and screws used to secure wire to these posts were too large, causing the post to be weakened and split under load. We have since replaced posts with 20 mm re-bar drilled through the deflectors. Post diameter and staple size should be considered when planning how to secure LWD.onsidered when planning how to secure LWD.)
• Case study:River Slea Rehabilitation  + (Work could not be carried out in section 3 … Work could not be carried out in section 3 due to the firmness of the riverbed. It is reccomended in the future that the firmness of the riverbed should be tested to ensure habitat improvement works can be carried out. </br>Install coir matting vegetation at the same time as installing brushwood, we had to rely on individual plug plants when planting.

• Case study:Cain weir removal  + (Working with a local contractor Seed and Spur, we were able to complete the works within the timescale and under budget of £750 in addition to SRT staff costs to prepare the consents, engage the business and monitor the work.)
• Case study:Lower River Roding Regeneration Project  + (You can set back flood defences even in highly constrained locations. In particular the A13 site is located next bridge supporting a major road into London. The steel sheet piling has been removed and intertidal banks have been restored.)

• Case study:Environmental design Mandalsvassdraget  + (expected soon...)
• Case study:Noard-Fryslân Bûtendyks Managed Realignment Scheme  + (implementation was delayed by one year due to difficulties with obtaining permits (due to objections from the local community).

Similarly, it is important to have good local networks & connections for project officers to contact and work with land managers</br></br>• Reliance on external funding (i.e. SRDP) for implementation was an issue: the project had no control over how this funding is allocated. As the farmers had to apply for and deliver the works, they had to take all the risks associated with delivery, which caused some reluctance to participate. </br></br>• Scoping of barriers long before implementation, such as conflicting land designations, pre-existing management restrictions , other biodiversity and archaeology interest is very important to limit snags during delivery.</br></br>• Where works were carried out using project funds, it would have been beneficial to provide contractors with templates of the information required during the procurement process, to allow them to meet the mandatory requirements more easily.o meet the mandatory requirements more easily.)
