A complete methodology for long-term water supply planning is presented. Based upon the characteristics of the water resources development planning problem (nonlinearity of cost functions, and hydrologic variables), the author rejects the seeking of "optimal" solutions and supports the seeking of "good enough" solutions. To answer the questions that are involved in long-term water supply planning, it is proposed to break down the problem into two simpler ones to be solved in a sequential fashion. Although mathematical guarantee of optimality cannot be assured, the introduction of physical and engineering constraints greatly increases the confidence in the final results. The proposed methodology allows deep analysis of the hydrologic aspects involved in water resources planning. The depth of hydrologic analysis is only restricted by available data and technology. In this respect, a method for synthetic generation of monthly runoff records in ungaged streams is proposed. An application of the methodology to the development of a Mexico City water supply plan is presented in full detail to appreciate its usefulness. Mexico City population forecast for the year 2000 is 28 million people. The estimated water demand in that year is 105 m³/sec, more than twice the present water supply of 50 m³/sec. To satisfy this demand, water has to be brought from four basins more than 150 km distant, and located at elevations more than 1,000 m below Mexico City's elevation (2,300 m above mean sea level). The water supply plan which resulted from this study indicates the most recommendable sequence for the development of the four basins, and the amount of water to be obtained from each one.

The most serious problems of urban transport in developing countries involve traffic congestion, insufficient space for pedestrians and other non-motorised modes, poor public transit service, the increasing attractiveness of the automobile due to rising incomes, and the chronic lack of financial resources required to make a concerted problem-solving effort. Many of the solutions suggested by planners and consultants from developed countries are both expensive and require a substantial time investment before the benefits can be realised. Others are politically unfeasible or not well-suited to the needs of the city in less developed countries. An indigenous response to the inadequate provision of urban transport in developing countries is the establishment of intermediate forms of public transport, such as jitneys or fixed-route shared taxis. These are able to provide levels of speed, comfort and convenience comparable to those of travel by private car, at considerably lower cost. Jitneys are relatively energy-efficient and consume much less road space per passenger than do private automobiles. The jitney originally developed in North America during the First World War, largely as a response to inadequate public transit service, but virtually disappeared again within a few years since the street railway operators were able to have legislation passed that made jitney operation uneconomic. In Third World cities, jitneys developed independently, and have enjoyed great success, in part due to a much greater demand for public transport and to fewer restrictive regulations. Mexico City is one of the largest urban areas in the developing countries and has a public transport system that includes a very extensive network of jitney services, several different classes of motor buses, trolley coaches, trams, four separate types of taxi services as well as a fast and efficient Metro system. These various elements of public transport are very interdependent and complementary, making remarkably good use of the available road space. A detailed examination of the jitney system in Mexico City, its regulation, organisation and economics was undertaken through personal observation and discussions as well as using an intensive survey of both jitney drivers and passengers. This has revealed that the jitneys are of great value, providing fast, frequent, comfortable and convenient public transportation which serves as a genuine alternative to private cars. The flexible nature of the jitneys makes them very demand-responsive and thereby efficient providers of urban transport. The jitneys employ a large number of people and are a profitable enterprise, contributing positively to the urban economy of Mexico City. / Arts, Faculty of / Geography, Department of / Graduate
