台灣地區因現有蓄水設施(水庫)應變、備源能力不足，需進行可能水庫壩堰勘查及評估，以提出可能壩(堰)址優選方案或進行跨流域水源調度來預做準備。為此，水利規劃試驗所(以下簡稱本所)已於民國102年至103年間，辦理「台灣地區可能壩堰址勘查規劃作業平台建置」計畫，建置含地文、雨量、流量及水庫壽命等分析模組之系統平台，提供可能壩(堰)址初步勘查規劃時所需之分析，亦獲得相當成果。 為快速的獲得水資源設施於可行性規劃階段所需之相關資訊，以簡化並協助水資源規劃作業，本所擬辦理「規劃作業平台建置─集水區水源應用結合空間環域分析研究」計畫，在前期計畫建置之分析模組與平台基礎上，結合各取水點時間、空間分布特性及其用水資訊，分析河川網路任一位置點剩餘水量及供水能力，建置上、下游取水點空間自動化分析模組與剩餘水量空間自動化分析模組，並辦理1年三條河川流域數位圖資建置，以利水資源規劃作業之進行並加速水資源開發；計畫總期程預計分3年期執行，本年度(104年)為第1年度。

Water conservation work is comparatively difficult in Taiwan because this island suffers by the uneven distribution of rainfall and coupled with rapid current of the rivers. Moreover, severe floods and droughts seem more frequent than before and the water demand in urban areas continues to grow, which have resulted in an urgent need to explore more water resource facilities to solve the problem of water shortage. Since collecting the geomorphologic and hydrological information for a proposed dam site is a time consumption work, to develop an efficient way for collecting and analyzing the related information is considered important. Consequently, an information system has been developed in this project based on open source GIS technique. There are total 9 river basins will be included in the information system within 3 years. In the first year project, the information system for Fengshan River, Houlong River, and Bazhang River basins were developed. Information systems for Lanyang River, Zhonggang River, Jishui River basins will be developed in the second year project, and Hualien River, Zhuoshui River, and Linbian River basins will be finished in the third year project. All the river basin systems will be integrated on an open source GIS platform to meet the requirement of preliminary planning work for water resource projects. In this project, a platform for water resources information was developed on an open source geographic information system (open source GIS). The system has integrated geomorphologic and hydrological calculation functions for available water analysis. The operating functions of the platform contain Water Resources Database, Pre-set Menu, Rainfall Analysis Module, Runoff Analysis Module, Reservoir Analysis Module, Upstream and Downstream Spatial Analysis Module, Surplus Water Analysis Module, Result Demonstration Module, and Updating Function. The system can estimate dam-backwater flooding area and reservoir capacity curves at any location in the watershed, and it can also afford detail information for runoff analysis, probable maximum flood, exceedance probability analysis, and surplus water analysis in the watershed. This integrated platform can provide a convenient way for engineers to obtain most of the required information while performing water resources planning and design work.
