松陰溪是松古盆地最重要的水系資源。松陰溪水利歷史悠久，水利工程消除農田旱災及水患，保證當地的農業灌溉水運、漁業、 糧食增產、居民日常用水等需求。

位于松陽縣城外橫山區塊白沙湖堤壩及發電站西南側的水利博物館，功能原為松陽縣河道堤防和水庫安全監測中心，包括監測大廳，水利部門辦公，食堂，檔案資料，防汛物資倉庫等。2016年結合松陰溪景區創建，將此項目擴大成松陰溪綠道上的水文公園，成為提供文化及休閑服務設施的關鍵節點。

水利博物館的建筑功能在原有基礎上重新調整， 將監測，檔案資料，食堂三部分原內部使用功能對外開放，檔案資料擴大作為水文歷史展廳，監測中心可以提供參觀和教學， 食堂對外營業作為休閑餐飲以及青少年活動區。

建筑體量以不同的形體區分表達功能屬性。公共功能以類似水利設施的弧形體量展開面向主要公共景觀，辦公服務設施則以長形建筑體量位于西側服務入口和南面后勤廣場。

不同弧段的公共體塊，強調體量感，如同水利設施的構筑物， 進一步將建筑表皮轉化為圓形劇場，增加戶外活動層次，通過步行路徑到達屋頂花園遠眺周邊景觀。由此產生的室內，在空間形態，序列，圍合，以及自然采光，都形成特定標識。建筑的內外進一步拓展重疊成兼具室內功能空間和室外活動場所的構筑物。

地面景觀則延續水文公園的水環境，與水利博物館的不同功能體量交匯，形成一系列的水庭院。線性或弧形步道在水面上交錯，以微型堰壩或廊橋的形態結合地形高差，重現松陽水利各種構成元素的空間體驗。

依托白沙湖水電設施的水利博物館和水文公園，通過功能定位以及空間體驗的多元性，展現松陽地方水利文化及生活形態，也成為縣城和鄉村交匯、城鄉共聯發展的一個重要節點。

Songyin River is the most important water resource in Songyang County. It has a long history of water conservancy, with water facilities spreading in the region to eliminate farmland drought and flood, and ensure the demand for agricultural irrigation, water transport, fishery, grain production and daily water consumption of local residents.

The Water Conservancy Center, located in the southwest of Baisha lake dam and power station out of county urban center, was originally planned as county water facilities management center, including monitoring hall, water conservancy department office, canteen, archives, flood control materials warehouse, etc. In 2016, to facilitate with the development of Songyin River Scenic District, the project was reprogrammed into a hydrological park to provide cultural and leisure services for Songyin River Green Belt.

The building programs was then readjusted by opening up the original internal functions of monitoring hall, archive and canteen to public. The archive can enlarge into an exhibition hall of local conservancy history. The monitoring center will be open by appointment to visitors and local schools as part of education program. The canteen will provide food & beverage and also function as multi-media space for teenagers.

Building volumes are differentiated by program. The public programs are unfolded into arc volumes similar to conservancy facilities, and service blocks are linear shapes.

The arc building envelop of public programs are further transformed into amphitheaters to provide surfaces for outdoor activities, and walkways to the roof gardens and viewing terraces. This brings a spatial identity to the interior, in terms of spatial form, sequence, enclosure, and natural lighting, etc. The interior and exterior of the volume are further interacted into a structure to accommodate both indoor programmatic space and outdoor activity surfaces.

The cluster of building volumes intersects with the water park on ground level to create a series of water courtyards. Passages on water surface adjusting to the topography as either micro dams or covered bridges will reproduce the spatial experience of various elements of Songyang water conservancy.

As one of the many infrastructure projects in Songyang County that are spreading along the outskirt of its urban center and mountain area, the Water Conservancy Center and Water Park could provide a connecting and interacting platform between urban center & rural villages.
