River Francolí is a small river in Catalonia (northeastern Spain) with an average annual low flow (~2 m(3)/s). The purpose of the River Francolí watershed assessments is to support and inform region-wide planning efforts from the perspective of water protection, climate change and water allocation. In this study, a hydrological model of the Francolí River watershed was developed for use as a tool for watershed planning, water resource assessment, and ultimately, water allocation purposes using hydrological data from 2002 to 2006 inclusive. The modeling package selected for this application is DHI's MIKE BASIN. This model is a strategic scale water resource management simulation model, which includes modeling of both land surface and subsurface hydrological processes. Topographic, land use, hydrological, rainfall, and meteorological data were used to develop the model segmentation and input. Due to the unavailability of required catchment runoff data, the NAM rainfall-runoff model was used to calculate runoff of all the sub-watersheds. The results reveal a potential pressure on the availability of groundwater and surface water in the lower part of River Francolí as was expected by the IPCC for Mediterranean river basins. The study also revealed that due to the complex hydrological regime existing in the study area and data scarcity, a comprehensive physically based method was required to better represent the interaction between groundwater and surface water. The combined ArcGIS/MIKE BASIN models appear as a useful tool to assess the hydrological cycle and to better understand water allocation to different sectors in the Francolí River watershed.
弗朗科利河是西班牙东北部加泰罗尼亚的一条小河，平均年径流量较小（约 2 立方米/秒）。对弗朗科利河流域的评估旨在从水保护、气候变化和水资源分配的角度支持和告知全流域的规划工作。在这项研究中，开发了弗朗科利河流域的水文模型，用作流域规划、水资源评估以及最终水资源分配的工具，使用了 2002 年至 2006 年的水文数据。为此应用选择的建模软件包是 DHI 的 MIKE BASIN。该模型是一种战略规模的水资源管理仿真模型，包括陆地表面和地下水文过程的建模。地形、土地利用、水文、降雨和气象数据用于开发模型分割和输入。由于缺少所需的流域径流量数据，因此使用 NAM 降雨径流模型来计算所有子流域的径流量。结果表明，如 IPCC 对地中海河流流域所预期的那样，弗朗科利河下游的地下水和地表水的供应可能面临压力。研究还表明，由于研究区域存在复杂的水文状况和数据稀缺，需要一种全面的基于物理的方法来更好地表示地下水和地表水之间的相互作用。ArcGIS/MIKE BASIN 组合模型似乎是评估水文循环和更好地了解弗朗科利河流域不同部门水资源分配的有用工具。
