Boating on Sussex Rivers
K1&A - Soo U n <zj r \ I A t 1" BOATING ON SUSSEX RIVERS NRA National Rivers Authority Southern Region Guardians of the Water Environment BOATING ON SUSSEX RIVERS Intro duction NRA The Sussex Rivers have a unique appeal, with their wide valleys giving spectacular views of Chalk Downs within sight and smell of the sea. There is no better way to enjoy their natural beauty and charm than by boat. A short voyage inland can reveal some of the most attractive and unspoilt scenery in the Country. The long tidal sections, created over the centuries by flashy Wealden Rivers carving through the soft coastal chalk, give public rights of navigation well into the heartland of Sussex. From Rye in the Eastern part of the County, small boats can navigate up the River Rother to Bodiam with its magnificent castle just 16 miles from the sea. On the River Arun, in an even shorter distance from Littlehampton Harbour, lies the historic city of Arundel in the heart of the Duke of Norfolk’s estate. But for those with more energetic tastes, Sussex rivers also have plenty to offer. Increased activity by canoeists, especially by Scouting and other youth organisations has led to the setting up of regular canoe races on the County’s rivers in recent years. CARING FOR OUR WATERWAYS The National Rivers Authority welcomes all river users and seeks their support in preserving the tranquillity and charm of the Sussex rivers. This booklet aims to help everyone to enjoy their leisure activities in safety and to foster good relations and a spirit of understanding between river users. -

Dear Consultee PUBLIC CONSULTATION on THE
Dear Consultee PUBLIC CONSULTATION ON THE PROPOSED CHANGES TO THE DOMESTIC SAFETY MANAGEMENT REGIME Introduction In 2001 Domestic Safety Management (DSM) was introduced by the Merchant Shipping (Domestic Passenger Ships) (Safety Management Code) Regulations 2001 (Statutory Instrument, SI 2001/3209). The DSM Code requires operators of domestic passenger ships to have a safety management system tailored to their specific operations. This safety management system should include: A health and safety policy Procedures to ensure the safe operation of ships with relevant duties Lines of communication between personnel ashore and afloat Procedures for reporting accidents Procedures for responding to emergency situations The DSM Code was developed to establish a common standard for the safe operation of passenger ships engaged on domestic (operating only in UK waters) trade and it applies to ships of Classes III, IV, V, VI and VI(A)1 and those certified under the Merchant Shipping (Passenger Ships) (Safety Code for UK Categorised Waters) Regulations 20102 (SI 2010/680). The objectives of safety management require the shipping company to apply simple and cost effect means of ensuring safety on board ships; preventing human injury and loss of life; and complying with applicable regulations and rules. No two ship operations are the same, and ships vary significantly in size and are employed under a wide range of different locations and conditions. The general principles to the safe operation of ships are consistent however, and can be expressed in such terms that they can be applied to a wide variety of ships. The proposed changes and rationale Existing legislation requires each UK domestic passenger ship to be audited for compliance with the DSM Code twice each year, whereas UK internationally operating passenger ships are only audited for compliance with the International Safety Management (ISM) Code twice in every five year period. -

Project Title: East Worthing FAS – Teville Stream Hydraulic Study Project Number: IMSO001181 Project Stage: Initial Assessment Environment Agency Project Manager: Contact Details for EAPM: Address: Telephone: E-mail: BRIEF DESCRIPTION OF PROBLEM: The Teville Stream lies within the town of Worthing, West Sussex. The River Adur Catchment Flood Management Plan (Capita Symonds, 2008) identified possible areas of flood risk, but did not carry out broadscale modelling of the catchment and instead based it’s assessment of risk on the Flood Zone maps. The CFMP states that the current baseline is insufficient to appropriately determine fluvial flood risk within the system. This project seeks to accurately determine the level of fluvial flood risk within the Teville Stream catchment area. The catchment is densely populated with much of the upper area being culverted and integrated with the surface water of the town. The semi-natural part of the upper watercourse is not very well defined, having several tributary streams and agricultural drainage channels. The main channel is a mixture of culverts and open sections, running under and alongside a pharmaceutical works, an industrial estate, historic landfill sites, a public amenity tip and a sewage works, finally emerging in an open channel which enters Brooklands Lake, a public leisure facility/boating lake occupying the area of the former tidal basin. This freshwater lake is maintained artificially by a terminal control structure at the seaward end, which drains into the sea after passing under the A259 seafront road. Flow from the north is augmented by runoff from the A27 highway and is discharged from a retention structure constructed on one of the tributaries. -
TARRING FLOOD ACTION GROUP Rain Garden Proposals
Active Community Fund GRANT APPLICATION FORM Section D: Your funding application Community Group Tarring Flood Action Group SuDs retro solutions to surface water flooding Project Title recommendations from earlier Feasibility study. Description of issues, needs and/or initiatives Within the West Tarring Conservation Area (See attached supplementary paper -map Appendix 1) there are a number of areas that large amounts of water collects on a regular basis, and more importantly, there have been a number of occasions in the recent past (2000, 2012) when flash floods have badly affected the area, resulting in flooding of, and damage to, a number of residential and commercial properties. Tarring High Street, in the conservation area, has had several floods in recent years and old buildings at the south end of the street and at the north end of South Street / Priory Close have suffered in particular. Following discussions at a TFAG Multi-Agency Meeting, the general consensus is that the floods were caused by a number of contributing factors:- • Climate Change impacting on localised intensity of rainfall • An inability of the network of drains and gullies to cope with heavy downpour events • Blocked drains and gullies • An aging, predominantly combined, surface water and sewage system • Discharge of roof water directly on to pavements/roads • Bow-wave surges caused by uncontrolled through-traffic • The influence of the Teville Stream and its confluence with Broadwater Brook, although this factor is subject to debate. • The lack of empirical data on problem areas of pooling and flooding in the Worthing area. • The dominance of a hard landscape and the lack of any ‘natural’ means of absorbing excessive rainwater before it can develop into flooding. -
Beach Recharge in Sussex & East Kent
BEACH RECHARGE IN SUSSEX & EAST KENT: A PRELIMINARY INVENTORY & OVERVIEW Compiled by R. Williams, edited by C. Moses. Not to be quoted without permission 1 Introduction .......................................................................................................................1 2 Inventory of beach recharge schemes ..............................................................................5 3 Notes and sources ............................................................................................................9 4 Conclusion ......................................................................................................................17 5 References......................................................................................................................21 1 Introduction Sand and shingle are being lost from many beaches in Sussex and Kent as a result of natural coastal processes as well as ill-designed sea defence and coastal protection schemes. To counteract falling beach levels, the Environment Agency and local authorities are increasingly resorting to “topping-up” the beaches with additional sand and shingle. Several terms are currently employed to refer to the artificial provision of extra beach material, but there is disagreement about their precise definition. For the purpose of this report, beach nourishment (or beach replenishment) is defined as the supply of material that has been dredged from the seabed or extracted from inland sand and gravel pits. Beach recycling is defined as the removal -

Worthing Core Strategy?
Core Strategy April 2011 Foreword Foreword This Core Strategy was adopted by Worthing Borough Council on 12th April 2011. The document, part of the Local Development Framework (LDF), will help guide planning and development in the Borough for the next 15 years and will be used to inform decision making on all planning applications. Regeneration is the key focus of the document with the strategic development at West Durrington and 12 areas of change identified as major regeneration opportunities. The Core Strategy also outlines how development needs will be met with a series of policies on key issues such as housing, employment, retail and environmental protection. An independent examination of the plan was carried out and the Inspector concluded that, ‘There is a clear vision at the heart of the Core Strategy of a thriving, prosperous and healthy town that plays a central role in the wider sub region.’ The document is the result of a number of years of preparation and consultation and we are really pleased that all the hard work has paid off and the Inspector has approved our plan and has confirmed it is deliverable. The Core Strategy is incredibly important, as it helps us work towards delivering a thriving and stronger Borough.

ANGLO-SAXON BURY Anglo-Saxon Bury an Early Medieval Port?
Research ANGLO-SAXON BURY Anglo-Saxon Bury An Early Medieval Port? ocated in the picturesque Arun LValley, the small village of Bury may have a hidden past as an Anglo- Saxon port. Initially, this seems rather far-fetched considering Bury’s current inland position in Sussex (Fig.1.), but one must consider that the coastline and river courses were signi cantly different in the 10th and 11th centuries. Not only were the coastal estuaries far more accessible, but river channels were wider and more liable to ooding (Robinson, An Historical Atlas of Sussex). River access to Bury via the River Arun was far from impossible in Anglo-Saxon Sussex. Indeed, this argument follows on A photograph of the old ferry at Bury taken c.1902, which illustrates the proximity of the village to the from what Ann Best maintained river.

Indeed, apart from Bury and the South Saxons). However, its status as a Hundred meeting place must surely be of some in uence to its royal proprietorship. A Hundred was a measure of land and an area served by the Hundred Court. This assembled on a monthly basis from the tenth century onwards, according to the Hundred Ordinance. James Campbell has argued that there was a deliberate tenth-century policy of ‘extending the weight of royal government to the countryside’ through this Hundred system (Campbell, The Fig.1. -
