本研究的目的是评估水文模拟程序- FORTRAN（HSPF），以更深入地了解亚拉巴马和密西西比（1，856平方公里的Luxapallila溪），沿海亚拉巴马（140平方公里的鱼河）的湿润亚热带流域，以及波多黎各（99平方公里的Rio Caonillas）的陡坡热带流域的高地流域水文过程的根本原因和机制。对于每个流域模型，降雨量，潜在蒸散量，径流时间序列从1999年1月至2000年12月被用来校准模型参数和2001年的时间序列被应用于验证模型结果。在各研究区，实际蒸散是水分流失的主要机制，其次是河流流量。年基流值的范围从58%的总排放量在Luxapallila河流域的84%，鱼河流域的总排放量。在Luxapallila溪和鱼河，间流是直接径流的主要机制，但在里约Caonillas直接径流的主要过程，地表径流。HSPF模型成功地适应了每日径流过程的模型在Luxapallila河流域和里约Caonillas流域的决定系数和纳什和Sutcliffe系数值在0.61和0.71之间的整个期间，但是，鱼河流域模型的性能较差。表现不佳可能是由于缺乏降雨时间序列内流域边界。总的来说，这项研究显示了HSPF模型在极端环境中的鲁棒性（小流域与大流域，平坦与丘陵地区，低与中/高径流潜力，热带海洋与潮湿的亚热带气候）。
The goal of this study was to evaluate the Hydrological Simulation Program – FORTRAN (HSPF) to gain more insight in the underlying causes and mechanisms of hydrological processes in an upland basin in Alabama and Mississippi (1,856-km2 Luxapallila Creek), a humid subtropical watershed in coastal Alabama (140-km2 Fish River), and a steep-slope tropical catchment in Puerto Rico (99-km2 Rio Caonillas). For each watershed model, rainfall, potential evapotranspiration, and streamflow time series from January 1999 to December 2000 were used to calibrate model parameters and 2001 time series were applied to verify model results. In each study area, actual evapotranspiration was the main mechanism of water loss followed by river discharge. Annual baseflow values ranged from 58% of total discharge in Luxapallila Creek basin to 84% of total discharge in Fish River watershed. In Luxapallila Creek and Fish River, interflow was the primary mechanism of direct runoff; however, surface runoff was the main process of direct runoff in Rio Caonillas. The HSPF model was successfully adapted to model daily streamflow processes in Luxapallila Creek basin and Rio Caonillas catchment with coefficient of determination and Nash and Sutcliffe coefficient values between 0.61 and 0.71 for the entire period; however, the Fish River watershed model performance was poor. The poor performance is likely due to the lack of rainfall time series available within the watershed boundaries. In general, this study showed the robustness of the HSPF model in extreme environments (small catchments vs. large basins, flat vs. hilly areas, low vs. moderate/high runoff potential, tropical marine vs. humid subtropical climates).
