Abstract

River flow characteristics and computational methods for converting sequences of monthly flows between natural and regulated conditions are explored based on experience in assessing water availability throughout the state of Texas in the United States. Diverse climate, hydrology, economic development, and water management practices across the state combined with continual population growth and implementation of a statewide water availability modeling system makes Texas an excellent case study of stream flow characteristics and modeling and analysis methods that are relevant worldwide. Stream flow is extremely variable, subject to severe multiple-year droughts, intense floods, seasonality, and continuous fluctuation. The effects of population and economic growth, water resources development and management, and climatic variability on river flows vary with different conditions found across the state. The modeling system provides capabilities for adjusting observed river flows to represent natural conditions, simulating regulated flows representing specified conditions of development, and performing statistical frequency and reliability analyses.

德克萨斯州自然和发达条件下的月度河流流量

河流的流量特征和计算方法转换自然和调节条件之间的月流量序列的基础上，在评估整个得克萨斯州的水可用性的经验，在美国进行了探索。不同的气候、水文、经济发展和整个州的水管理实践，加上持续的人口增长和全州范围内水资源可用性建模系统的实施，使德克萨斯州成为溪流流动特征、建模和分析方法的优秀案例研究，与全球相关。河流的流量变化很大，受到多年严重干旱、强烈洪水、季节性和持续波动的影响。人口和经济增长、水资源开发和管理以及气候变化对河流流量的影响因州内不同条件而异。建模系统提供了调整观察到的河流流量以表示自然条件的能力，模拟代表特定发展条件的调节流量，并执行统计频率和可靠性分析。
