AN ANALYTICAL FRAMEWORK FOR EVALUATING CHANNEL MAINTENANCE FLOWS IN COLORADO1

ABSTRACT: An accounting procedure is developed which determines a flow regime that is capable of transporting an amount of bedload sediment necessary to ensure channel stability downstream. The method allows for sediment buildup in the channel within geomorphic threshold limits during low flow periods. During periods of high runoff, enough water is bypassed to transport the stored sediment. The procedure utilizes only those flows of sufficient magnitude to maintain channel stability over the long run (25–50+ years). An example is presented which determines the volume of water and frequency of release for channel maintenance purposes downstream from a hypothetical water diversion project. Of some 1,200,000 acre feet generated during a 59-year period, 86,500 acre feet was required for channel maintenance flows. Bypass flows were not required each year, but only during those years when average daily flow reached bankfull or greater. Such releases were made on 202 of the 411 days when average flows either equalled or exceeded bankfull discharge.     

Comparing theoretical and actual feasibility of transferring management of river lift irrigation systems in Sudan

This article focuses on agricultural production in lift irrigation schemes along the White Nile in the Sudan. A comparison is drawn between the theoretical forecast and actual practical experience regarding the feasibility of transferring management from government-run parastatal organizations to private farmer organizations. Although the theoretical model indicates that farmers should be able to cover the cost of managing the river lift irrigation systems, field data show, however, that farmers growing wheat are barely able to break even. Even assuming a doubling of the present wheat yields, the cash surplus earned would only suffice for fuel to operate the pumps. Under these circumstances, it is not surprising that, contrary to government expectations, the private sector has been unenthusiastic about taking over management of White Nile river lift schemes. The lessons that emerge from this study indicate that unplanned and rapid withdrawal of state management can lead to negative results. The transfer of management responsibility for the river pumps does not appear to influence economic performance considerably, which depends on the wider context of the country's economic, political and institutional environment, within which the agricultural sector functions.     

试论火警等级设定与调度指挥

为了规范接处警调度指挥程序,确保灭火救援力量调度准确及时,笔者就火警等级设定在国家尚未定论的情况下,依据接处警的经验,以及按火警发生的类型、规模、时间给予了等级定义,将火警分为1～5级,一级为最低级,五级为最高等级,等级设定旨在便于灭火救援的调度指挥。同时,结合苏州市多种形式消防队力量较强的状况,对1～5级火警的消防调度、组织指挥、等级汇报提出了符合较发达地区消防特点的调度指挥方案,使之在处警时有计划地调动就近的公安、专职等多种形式消防队,真正使多元化的消防力量能够共同参与、上下联动、形成合力,在最短的时间内控制灾情。
