The use of computer models in planning upland land use

The British Ecological Society has suggested that computer‐based techniques could be used in the coordination of policies across different land uses in upland planning. This paper looks briefly at one such technique — a linear programming model — and describes its use at a regional scale for the Sedburgh area in north‐west England. The paper concludes with consideration of why such models are not in more common use.     

On designing streets: an interactive perspective

The following is a summary of work carried out in urban planning design at the University of Newcastle upon Tyne. The main objectives of the study were to identify those factors which condition the use of a street and to understand the physical and emotional impacts of the street and its different characteristics upon its users; eventually this led to establishing facts involving the criteria which contribute to making streets which would enrich peoples’ experience and would contribute to the urban life and excitement of all.     

APPLICATION OF CRITICAL PATH METHOD TO WATER RESOURCES PLANNING1

ABSTRACT. The task of resource management, in this case water resources, is rapidly becoming more complex, particularly because decision making is often contingent upon various prior activities and sets of data. Comprehensive planning is required in order to prevent misallocation of resources or mismanagement in resource development. Such planning involves five general phases which are applicable to any problem faced by society: (1) problem identification; (2) formulation of alternatives; (3) evaluation of alternatives; (4) implementation; (5) review. There have been many attempts to simplify the planning process and effectively carry out these five phases. The experience of the Alberta Water Resources Division has been that the Critical Path Method is one of the most useful tools available today for planning. It involves two basic steps: (1) preparation of a network diagram which (a) identifies all the activities necessary for the completion of a project, (b) correctly sequences these activities, (c) allocates resources; and (2) mathematical computations for scheduling the activities. In other words, this approach breaks a task down into smaller units or activities for easier organization, scheduling, and performance for eventual completion of the project. This paper will illustrate the effectiveness of the Critical Path Method by discussing its application to actual water resources projects.     

COOPERATIVE COMMUNITY-UNIVERSITY WATER RESOURCE PLANNING: AN INTERDISCIPLINARY APPROACH1

ABSTRACT. This paper outlines an approach to planning the management of a lake heavily used for recreation and of substantial importance to the tourist economy of Northeastern Wisconsin. A framework, utilizing a three dimensional matrix, is developed to analyze levels of public concern, management alternatives and action agencies. Structural and non-structural alternatives are examined and evaluated on the basis of social and economic criteria, long- and short-term environmental impact and legal-political feasibility. Data requirements which created the necessity for an interdisciplinary approach involving social, physical, and biological sciences are enumerated. The authors examine the role of universities in assisting communities with resource management planning and detail the attributes of academic institutions which desire to successfully attack resource planning problems.     

MULTI-CRITERION RANKING OF ALTERNATIVE LONG-RANGE WATER RESOURCE SYSTEMS1

ABSTRACT The definition and comparison of alternative water resource systems designed to meet long-range goals (say 60 years) is illustrated by a case study in Hungary. A comprehensive cost-effectiveness approach is adapted to define goals, specifications, criteria, alternatives and their capabilities. Specifications include demands given in probabilistic terms. The comparison of alternative systems is based on 12 criteria, one of which is the balance between total energy consumed and peak energy produced. Important factors involving social elements, such as flood protection and land and forest use, are described both as monetary quantities and as qualitative appreciations. Five alternative systems are defied involving flat land reservoirs, pumped storage reservoirs, interbasin transfer, and conjunctive use of surface and ground water. International cooperation is then used to rank systems and reduce the problem to a tradeoff between only two alternatives.     

DECISION PARAMETERS FOR COMBINED USE OF EFFLUENT DISCHARGES,SURFACE FLOWS,AND GROUND WATER1

ABSTRACT: Decision parameters affecting combined use of effluent discharges and surface flows and ground water available at Gillespie Dam on the Gila River in Arizona are identified and analyzed. Hydrologic, economic, legal, and institutional parameters are considered separately and in combination. The interrelationships of irrigation subsystems, water use functions, institutional involvement, economic and legal constraints are illustrated. Recent hydrologic studies indicate that the natural flow of the Gila River will increase with the discharge of Phoenix sewage effluent and then there will be a drastic decline when the Palo Verde Nuclear Generating Station commences in 1985. Competition for any increases in effluent discharges and surface flows could be ameliorated through the combined efforts of existing or reorganized entities resulting in sharing of costs and benefits. The analysis leads to recommendations concerning joint use of facilities, proration of fixed and variable costs, and creation of a mutual water company.     

WATER QUALITY MANAGEMENT: THE CASE FOR RIVER BASIN AUTHORITIES1

ABSTRACT: There is a lamentable absence of comprehensive planning in the current cursade to improve water quality. A serious shortcoming is the lack of evaluation of the effects of waste water treatment upon environmental quality. At some point in time the public may ask what they have obtained for their money. The nature of pollution in a river basin demands a coordinated attack against it. Engineering and economic criteria suggest that a properly empowered river basin authority would be the logical organization to plan and operate a water quality management system. Several forms of such authorities have operated effectively and efficiently for many years in the United States and other industrialized countries. Examples of successful river basin authorities and their advantages and methods of operation are discussed.     

ENVIRONMENTAL CONSIDERATIONS IN CORPS PLANNING1

ABSTRACT: Survey data from samples of two types of Corps of Engineers planning studies have been collected. The nature of significant environmental issues affecting the studies was ascertained. Information concerning District administrative practices and communication patterns and extraorganizational coordination procedures was also obtained. Statistical analysis examined the relationships between these practices and procedures and the consideration given environmental issues in plan formulation and modification decisions. Environmental issues receive greater consideration in plan formulation decisions where District policies encourage interdisciplinary planning and direct communication between planners and environmental interests. Plan modification decisions reflect environmental considerations to a greater degree where significant controversy exists and where reviewing agencies actively pursue environmental issues.     

A training consultancy for an Ethiopian I.D.A. urban programme evaluated

The author contributed to a short ‘in service’ course for staff engaged on a World Bank upgrading project for Ethiopian housing. The project includes both the building of new houses by self‐build co‐operatives on the periphery of Addis Ababa, and the upgrading of a dense inner city area in conditions of acute deprivation. The paper is a highly personal account of the author's impressions of the value of such initiatives.
