Item Open Access Anglian Region: River Yare, River Wensum, Woldgrift Drain(National Rivers Authority, 1996) Dunderdale, J. A. L.; Morris, J.This document describes methods, results and conclusions of a study to evaluate the impacts of alternative river maintenance strategies on the River Yare and Wensum and the Woldgrift Drain in the Anglian Region. Its main purpose are to provide supporting information for R&D Note 456 'River Maintenance Evaluation' and to provide data which supports routines for the prioritisation and programming of river maintenance.Item Open Access Drainage benefits and farmer uptake(Severn Trent Water Authority, 1984-07) Morris, J.; Hess, Tim M.; Ryan, A. M.; Leeds-Harrison, P. B.As part of the Severn Trent Water Authority's need to improve managerial decision on future projects, post appraisals of completed projects have been instigated. These can involve either a comprehensive review of all aspects or the project or, alternatively, can consider key parameters only. In the case of agricultural land drainage schemes key parameters have been identified as the benefits resulting from schemes and the rate of uptake of these benefits by farmers. The investment of public funds in improved agricultural land drainage is normally justified in terms of the resultant net increase in the value of agricultural production.Item Open Access Economic basis and practicalities of washland creation on the somerset levels and moors(Cranfield University, 2002-01) Morris, J.; Vivash, R. M.; Alsop, D.; Lawson, C. S.; Leeds-Harrison, P. B.; Bailey, A. P.In Somerset, the Wise use of Floodplains (WUF) Project has developed new ways of helping stakeholders in the River Parrett Catchment to find sustainable solutions for the management of water, both in flood events and throughout the year.Item Open Access The evaluation of river maintenance(Cranfield University, 1993-05) Morris, J.; Sutherland, D. C.Rivers serve a variety of interests including those of water supply, drainage, environmental quality, and recreation. One of the main functions of managed rivers is to dispose of surplus water from urban and rural areas. In the case of rural areas this drainage function relates to the control, within acceptable limits, of flooding and water table levels on riparian, mainly agricultural land.Item Open Access Evaluation of weed maintenance activities on the river Idle(Cranfield University, 1993-09) Sutherland, D. C.; Morris, J.Silsoe College was asked by the Lower Trent Area of the Severn Trent Region of the National Rivers Authority (NRA) to evaluate the current weed maintenance regime on the River Idle, north Nottinghamshire. The study required the assessment of the benefits of regular weed maintenance activities to users of the river and the disbenefits incurred if weed maintenance was not to be carried out.Item Open Access Farmer uptake of drainage benefits a regional study(Cranfield University, 1987-01) Morris, J.; Black, D. E.; Hess, Tim M.The commitment of public funds to land drainage improvement such as river flood alleviation and improved arterial systems, has been an important component of agricultural support in Britain. The economic performance of these investments depends on whether private farmers actually exploit the potential benefits afforded. Pre-investment appraisals of agricultural land drainage schemes have been criticised for their arbitrary and optimistic predictions of benefit uptake whilst the great variation in benefit uptake between schemes and farmers has hitherto remained unexplained. More recently, in the face of changes in agricultural policy, pressure on public funds, and competition from other land users, there has been a call for a more consistent and objective method for evaluating public sector land drainage investments (HMSO, 1995).Item Open Access North West region: River Wampool, Pilling Water(National Rivers Authority, 1996) Dunderdale, J. A. L.; Morris, J.Item Open Access River maintenance evaluation(National Rivers Authority, 1996) Dunderdale, J. A. L.; Morris, J.In January 1989, the National Rivers Authority (NRA) Severn Trent Region commissioned Silsoe College to undertake a three year study to monitor and evaluate the impact of maintenance on six of its main river sites. The study developed methods for the technical and economic appraisal or fiver maintenance. Subsequent to this, the study was extended to incorporate other NRA Regions, and further develop methods to help design, justify and prioritise maintenance activities. The study reported below involved the monitoring of 12 sites in five NRA Regions during the period March 1992 - October 1995, and further development of guidelines for the management of the maintenance function.Item Open Access Severn Trent Region: River Sence, Hinlton Brook(National Rivers Authority, 1996) Dunderdale, J. A. L.; Morris, J.This document describes methods, results and conclusions of a study to evaluate the impacts of alternative river maintenance strategies on the River Sence and Hilton Brook in the Severn Trent Region. Its main purpose are to provide supporting information for R&D Note 456 'River Maintenance Evaluation' and to provide data which supports routines for the prioritisation and programming of river maintenance.Item Open Access South West Region: River Yarty, Sir Arthur's Pill(National Rivers Authority, 1996) Dunderdale, J. A. L.; Morris, J.This document describes methods, results and conclusions of a study to evaluate the impacts of alternative river maintenance strategies on the River Yarty and Sir Arther's Pill in the South Western Region. Its main purpose are to provide supporting information for R&D Note 456 'River Maintenance Evaluation' and to provide data which supports routines for the prioritisation and programming of river maintenance.Item Open Access Welsh region: River Arrow, Dreneuydd/Broadway Reen, Dysynni Low Level Drain(National Rivers Authority, 1996) Dunderdale, J. A. L.; Morris, J.This document describes methods, results and conclusions of a study to evaluate the impacts of alternative river maintenance strategies on the River Arrow Dreneuydd Broadway Reen and the Dysynni Low Level Drain in the Welsh Region. Its main purposes are to provide supporting information for R&D Note 456 'River Maintenance Evaluation' and to provide data which support routines for the prioritisation and programming of river maintenance.
