水文博物馆

Location: Baisha Lake Power Station, Hengshan Mountain, Songyang

Completion: 2018

松阴溪是松古盆地最重要的水系资源。松阴溪水利历史悠久，水利工程消除农田旱灾及水患，保证当地的农业灌溉水运、渔业、 粮食增产、居民日常用水等需求。

位于松阳县城外横山区块白沙湖堤坝及发电站西南侧的水利博物馆，功能原为松阳县河道堤防和水库安全监测中心，包括监测大厅，水利部门办公，食堂，档案资料，防汛物资仓库等。2016年结合松阴溪景区创建，将此项目扩大成松阴溪绿道上的水文公园，成为提供文化及休闲服务设施的关键节点。

水利博物馆的建筑功能在原有基础上重新调整， 将监测，档案资料，食堂三部分原内部使用功能对外开放，档案资料扩大作为水文历史展厅，监测中心可以提供参观和教学， 食堂对外营业作为休闲餐饮以及青少年活动区。

建筑体量以不同的形体区分表达功能属性。公共功能以类似水利设施的弧形体量展开面向主要公共景观，办公服务设施则以长形建筑体量位于西侧服务入口和南面后勤广场。

不同弧段的公共体块，强调体量感，如同水利设施的构筑物， 进一步将建筑表皮转化为圆形剧场，增加户外活动层次，通过步行路径到达屋顶花园远眺周边景观。由此产生的室内，在空间形态，序列，围合，以及自然采光，都形成特定标识。建筑的内外进一步拓展重叠成兼具室内功能空间和室外活动场所的构筑物。

地面景观则延续水文公园的水环境，与水利博物馆的不同功能体量交汇，形成一系列的水庭院。线性或弧形步道在水面上交错，以微型堰坝或廊桥的形态结合地形高差，重现松阳水利各种构成元素的空间体验。

依托白沙湖水电设施的水利博物馆和水文公园，通过功能定位以及空间体验的多元性，展现松阳地方水利文化及生活形态，也成为县城和乡村交汇、城乡共联发展的一个重要节点。

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.
